Joyetech eGo AIO 2 Review | Battery Life and the 7–Color Display ARE Exceptional!

Richard WinterMods 8 Comments

Welcome to another review from Vaping Hardware. This time we’re looking at the all new Joyetech eGo AIO 2. It’s an All-In-One (AIO) vape kit that’s undergone a redesign and face-lift from the original eGo AIO, a device that’s been hugely successful for several years now.

Joyetech eGo AIO 2 in front of its packaging

This is a first for us here on two fronts; this being the first Joyetech product we’ve reviewed and the first AIO device we’ve had the pleasure of using.

For those of you who are unaware what an AIO device is, in its simplest term; an AIO is a device that has its tank (e-liquid storage) built into the battery/body. Unlike traditional 510 threaded tanks where the tank and mod body are separate, the coil on the eGo AIO 2 is screwed into the top cap section which then directly connects into the tank section of the eGo AIO 2 body/battery.

There are pros and cons to these types of devices and the term AIO at times can be a bit misleading as it’s often associated with pod devices too. This is a bit of a grey area and as such we do plan to cover this in a separate guide in the near future.

As we’ve not used or reviewed the original Joyetech eGo AIO, we won’t discuss any design updates or changes from the original but instead focus on the eGo AIO 2.

Overview of the Joyetech eGo AIO 2

The Joyetech eGo AIO 2 is a variable top airflow all-in-one device producing a vape style between an airy Mouth-To-Lung (MTL) and Restricted-Direct-To-Lung (RDL) draw.

Joyetech eGo AIO 2with the two included BFC 0.8 ohm coils and the top cap removed

It incorporates a child resistant top cap with a removable 510 mouthpiece and comes with 2 brand new BFC 0.8 ohm replaceable Mesh coils. The internal tank capacity is 2ml and the output power, although not specified, is derived from the constant voltage output of the 1700mAh internal rechargeable battery.

Firing the eGo AIO 2 is via push button control which also turns the device on/off. Filling the eGo AIO 2 is carried out by removing the top cap and adding e-liquid directly into the top opening of the internal tank. A Type-C USB charging port, specified as 5V/1A will charge the eGo AIO 2 using the supplied charging cable in 1.5 hours. See How do I Charge the eGo AIO 2 Battery section for a more measured charge time.

Its design is a pen style device with two oval e-liquid viewing windows and it’s constructed out of aluminum alloy, measuring 123 mm tall by 19mm in diameter. There are 4 different colors available; Shiny Silver, Mysterious Black, Rich Blue and Rose Gold.

There are no control or adjustment buttons other than the on/off/fire button with the only display being a 7-color LED indicator inside the tank window which illuminates when the fire button is pressed. These LEDs also correspond with the remaining charge left in the battery. They also illuminate while the battery is being charged and display any safety/fault conditions.

Considering its small size, the eGo AIO 2’s 1700mAh capacity battery is pretty hefty! But that’s not all…The 7-color remaining battery charge status tank light is the best I’ve come across. As for battery life, it’s not that often I’m left speechless but it really is exceptional. I’ve covered this in more detail in the Battery Performance section of this review.

I would like to thank Yvonne at MyVapor for sending me the Joyetech eGo AIO 2 kit for the purpose of this review. As always this review is completely unbiased and my honest opinion based during my time using and reviewing the supplied eGo AIO 2.

What’s in the Box?

Joyetech eGo AIO 2 Whats In The Box
  • Joyetech eGo AIO 2 Device
  • 2x BFC 0.8 ohm Mesh Coil
  • Type-C USB Cable
  • User Manual
  • Warranty Card

Note: There are 2 different kits available. The one we received is called the “Advanced Kit” which includes the above contents. The “Simple Kit” is a smaller option and I’m guessing a cheaper one which doesn’t include a Type-C USB cable and only includes 1 BFC 0.8 ohm coil.

The Joyetech eGo AIO 2 packaging consists of a standard cardboard box with an outer slide off sleeve. The overall dimensions of the packaging measure 141.2mm tall by 78.5mm wide by 27mm deep.

Once the slide off sleeve is removed, the eGo AIO 2 sits in an open tray with a separate compartment that sits next to the tray with a lift to open lid. This compartment houses the remaining kit contents such as the 2 coils, USB charging cable, user manual and warranty card.

Preparing to Use the Joyetech eGo AIO 2

When you first unbox the eGo AIO 2 you’ll need to unscrew the top cap and screw one of the included coils into the base of the top cap.

0.8ohm BFC coil screwed into the underside of the top cap

I would suggest turning on the eGo AIO 2 at this stage by pressing the on/off/fire button 5 times. The colored light in the tank area will flash 3 times.

Max e-liquid level line on the eGo AIO 2

Fill the tank with your e-liquid up to the “Max” e-liquid line that’s etched next to the e-liquid viewing window. Drip a few drops of e-liquid into the coil’s wicking ports and then screw the top cap with the coil attached to the eGo AIO 2 body. Do NOT fire the device at this stage.

As you tighten the top cap, when the coil makes contact with the base plate in the bottom of the tank section, the 7-color light will illuminate once indicating the eGo AIO 2 is functioning correctly.

Note: The top cap has a child lock “push down and twist” action to open/close. Tightening the top cap down too tightly stops the eGo AIO 2 from working, as pressing the fire button made the colored light flash. I found the ideal was to screw the top cap in until the top cap keeps spinning around and then lightly push down the top cap and just tweak it a further sixteenth of a turn.

Make sure you leave the Joyetech eGo AIO 2 filled with e-liquid to stand for approximately 10-15 minutes before you first fire the device so the e-liquid has fully saturated the wicking material.

The eGo AIO 2 comes with a nominal charge so it can be used straightaway but we do recommend fully charging the device before you first use it.

Joyetech eGo AIO 2 Kit Design and Appearance

Joyetech eGo AIO 2 with no coil fitted and view of the square button

The Joyetech eGo AIO 2 is a slim pen style All-In-One (AIO) device with a fixed wattage output derived from the constant voltage output of the internal 1700mAh capacity battery. It’s constructed out of aluminum alloy which gives it a quality robust feel and it measures 123mm tall by 19mm in diameter with a weight of 72 grams including the coil.

A single square matte black 8mm by 8mm button on the side of the battery/body turns the eGo AIO 2 on/off by pressing 5 times in quick succession. This button also serves as the fire button providing a fast firing speed. It’s good to see the button has a positive “click” feel to it and doesn’t suffer from any button rattle.

Joyetech eGo AIO 2 with the 5V/1A Type-C USB charging port

Because the eGo AIO 2 incorporates an internal battery, charging is carried out using the supplied charging cable connected to the Type-C USB port placed on the reverse side to the fire button. This port is specified as 5V/1A with a charging time of 1.5 hours to fully charge the battery.

It’s not the quickest of charges by any means and unfortunately the specified 1.5 hours is incorrect, in fact it’s way off! I monitored the charging time on 3 separate occasions and each time it took in excess of 2.5 hours. While I prefer to slow charge any battery, this is a long time. Fortunately because the eGo AIO 2 has pass-through, you can still vape while it’s being charged.

Joyetech eGo AIO 2showing e-liquid window, Max e-liquid line, fire button

Above the Type-C USB port and on/off/fire button are two large 17mm by 11mm clear oval shaped e-liquid windows giving total visibility of the remaining e-liquid level in the internal tank. There is also a screen printed “Max” e-liquid level line next to the window.

It’s important when filling the tank that you don’t overfill with e-liquid and exceed the “Max” line. Even though there appears to be more room left in the tank, once you place the top cap on with the attached coil, the e-liquid level will increase.

Flat base of the Joyetech eGo AIO 2

Moving down to the base of the eGo AIO 2, it’s flat so stands upright when placed on a surface. There is a battery venting hole in the center of the base as a safety precaution in case the battery needs to vent. The standard “CE” and “Do Not Dispose” markings are printed on this base.

Back up to the top of the eGo AIO 2 is where things get really interesting…

Top cap removed from the eGo AIO 2 body
Underside of top cap on the eGo AIO 2

We have a threaded removable child proof top cap that incorporates a rotating variable airflow control and a removable 510 drip tip (mouthpiece). The underside of the top cap provides the threaded mounting where the BFC coil is screwed into.

This top cap, once unscrewed and taken off, allows access to the internal glass tank that forms part of the eGo AIO 2 body (it’s not removable). Filling is carried out with this top cap removed and your e-liquid added directly into the glass tank. For once we don’t have to squeeze our e-liquid bottle tips into a small opening!

Airflow control indents on the outer ring and drip tip shroud

Airflow is different from the usual control ring or slider found on the majority of mods where you can see the change in the air inlet opening. Instead the outer ring of the top cap rotates and relies on aligning a small indent on the outer ring with a similar indent on the inner mouthpiece section.

Indents aligned restricting the airflow on the eGo AIO 2
Indents 90 degrees apart opening the airflow on the eGo AIO 2

When the two indents align, the airflow is opened producing a fairly unrestricted draw. Rotating the outer ring either left or right so the two indents are 900 apart will restrict the airflow and tighten the draw. Obviously the airflow can be tweaked between these two points to fine tune your draw. The strange thing here though is there is no visible difference in the outer ring other than the alignment of the two indents.

In summary:

  • Indents aligned: – Unrestricted draw
  • Indents 900 apart: – Restricted draw

Before we move away from the top cap, the other interesting point is the placement of the coil. Unlike standard tanks or pods where the coil is secured into the bottom of the tank, the eGo AIO 2 BFC coil is screwed into the underside of the top cap which is then lowered into the liquid reservoir (internal tank) section of eGo AIO 2 body.

The coil that comes with the eGo AIO 2 is a new BFC 0.8 ohm Stainless Steel Mesh coil and fortunately the kit includes 2 of these. The unique feature of this coil is the side and bottom e-liquid inlets which ensure a smoother e-liquid delivery to the coil. The original eGo AIO utilized the BF range of coils which are also compatible with the eGo AIO 2 and equally the new BFC coil works with the original eGo AIO!

  • BF SS316 0.5 ohm Coil
  • BF SS316 0.6 ohm Coil
  • BF SS316 1.0 ohm Coil
  • BF Clapton 1.5 ohm Coil

Now I’ve left the best bit till last… and I really am IMPRESSED with this function. The eGo AIO 2 has a 7-color LED indicator that illuminates when the device is switched on/off, when the fire button is pressed and when it’s being charged. It will also display any of the safety features.

Joyetech eGo AIO 2 7-color LED illuminated through the e-liquid viewing window

The position of this 7-color LED is placed inside the internal tank and when illuminated shines through the 2 e-liquid viewing windows. It’s fairly bright and really does look very effective against the e-liquid in the tank. Not only this, it’s a great way of seeing the remaining e-liquid left in the tank.

LED color change of the battery charge on the eGo AIO 2

This 7-color LED provides a perfect indication of the remaining battery status, showing different colors at each stage of battery discharge as follows:

  • Red:                0% – 10% of charge
  • Purple:             10% – 25% of charge
  • Yellow:            25% – 40% of charge
  • White:              40% – 55% of charge
  • Blue:                50% – 70% of charge
  • Cyan:               70% – 85% of charge
  • Green:             85% – 100% of charge

Safety features are also displayed, such as:

  • Overtime Protection
  • Low Battery Protection
  • Over Discharge Protection
  • Over Charge Protection
  • Atomizer Short-Circuit Protection
EGO AIO 2 and Joyetech Branding

Branding on the Joyetech eGo AIO 2 is very discreet and limited to “EGO AIO2” screen printed in small lettering just below the square on/off/fire button and “Joyetech” screen printed within the multiple vertical lines around the device that cover just under half of the body length.

There are 4 colors available in the Joyetech eGo AIO 2 range with each color surface a satin finish. The color we received for this review is ‘Shiny Silver’ which can be seen in the photos throughout this review:

  • Shiny Silver
  • Mysterious Black
  • Rich Blue
  • Rose Gold
4 different colours of the Joyetech eGo AIO 2

Joyetech eGo AIO 2 Kit Functionality

The Joyetech eGo AIO 2 kit is straightforward to use and very easy to operate. Despite its simplicity it IS a very good vape device and performs really well. Its functionality stops at an on/off/fire button and variable airflow control. It doesn’t have variable wattage control, instead the power is fixed and derived from the constant output voltage and the resistance of the coil.

Joyetech RED led thru e-liquid window while its being charged

A 7-color LED inside the glass internal tank provides the user interface (UI) highlighting the current status of the internal battery when the fire button is pressed and when it’s being charged. It will also indicate if any safety features are exceeded.

I’ve used and reviewed many pods and mods over my time and while it doesn’t have an OLED display showing the fancy things such as wattage, coil resistance and puff counter etc, this 7-color LED really is one of the best displays I’ve come across.

Variable airflow is controlled by rotating the top cap; indents aligned increases the airflow while the indents 900 apar will restrict the airflow and tighten the draw. It’s simple but effective.

Turning the eGo AIO 2 on/off is carried out by pressing the fire button 5 times in quick succession.

The on-board electronics that control the Joyetech eGo AIO 2 maintain a constant output power throughout the discharge cycle of the battery, providing a responsive fire button activated vape. This chip set also controls the included safety features/operations and provides the visual indication via the 7-color LED:

  • Turning On/Off: – LED flashes 3 times
  • Fire button pressed: – LED illuminates in one of 7 colors
  • Charging: – Red LED remains illuminated
  • Full charge: – LED extinguishes
  • Coil inserted: – LED illuminates once
  • Low battery: – LED flashes red 5 times
  • Overtime protection: – LED flashes 2 times

Remaining Battery Charge Status

When the fire button is pressed, the 7-color LED will illuminate through the 2 e-liquid windows in the color corresponding to the remaining charge left in the battery:

  • Red:                0% – 10%
  • Purple:             10% – 25%
  • Yellow:            25% – 40%
  • White:              40% – 55%
  • Blue:                50% – 70%
  • Cyan:               70% – 85%
  • Green:             85% – 100%

I did try to take photos of the different colors but after many hours I gave up as I just couldn’t get them good enough. Note to myself…..must try harder! I ended up taking a screen shot of 5 of the colors from the Joyetech website just so you get the idea:

Blue LED display on the eGo AIO 2
Green LED display on the eGo AIO 2
Purple LED display on the eGo AIO 2
Red LED display on the eGo AIO 2
Yellow LED display on the eGo AIO 2

An observation I found was the threshold point at each color change would sometimes revert back to the previous color. For example; if the 7-color LED was showing “Green” and then the next fire button press it changed to “Cyan”, if you didn’t press the fire button again for a few minutes the color would revert back to “Green”.

Once the battery percentage changes from the cut-over threshold, the color will remain as per that percentage range (see threshold chart above) until the next threshold is reached when it will then change again.

Once the battery becomes discharged, the 7-color LED will flash red 5 times and you will no longer be able to vape. At this point, the eGo AIO 2 will require recharging.

Battery Charging Status

When the eGo AIO 2 is placed on charge, the 7-color LED will illuminate “Red” and remain illuminated throughout the charging cycle. Once full charge is reached, the “Red” LED will extinguish.

The eGo AIO 2 does have Pass-through so you can vape while it’s being charged.

Overtime Protection

When your draw on the eGo AIO 2 for longer than 10 seconds, the LED will flash 2 times and the vape will cut off.

Joyetech eGo AIO 2 Performance

Once I worked out how the coil fitted and why when I screwed the top cap in too tight it wouldn’t work, I was finally up and running. I only used the new BFC 0.8 ohm coil(s) during the testing as these are the only coils supplied with the kit.

I won’t bore you with the different flavors I cycled through the tank or their PG/VG ratio, other than to say that with each flavor I tried the coil worked really well. Flavor and vapor are very good and the throat hit I got from the 6mg freebase juice was spot on. Nic salts worked equally well too.

Airflow was good and found that I could go from a RDL to a DTL vape style depending on the position of the airflow setting. Being used to the normal ‘Cyclops’ style airflow openings or the lever type where you can see what opening you have, the little indent markings on the eGo AIO 2 did take a bit of getting used to.

The fire button worked every time giving an instant responsive draw. While drawing on the mouthpiece, it is a little noisy. I couldn’t find out what the wattage is set to when using the 0.8 ohm coil but it did feel like a reasonably high wattage so it’s understandable why it’s a little noisy.

At the time of writing this review, I’ve used the same coil for over 2 weeks and it’s showing no signs of faltering with no loss of flavor or vapor. To date I’ve filled the reservoir (tank) approximately 40 times and am still really enjoying the results.

My only issue was the gurgling after the majority of refills. This was easily rectified by turning the eGo AIO 2 upside down and tapping the mouthpiece on a tissue to expel the excess e-liquid in the chimney.

The transparent e-liquid windows are perfect for viewing the remaining e-liquid level and the color change visible through these windows gave an accurate account of the remaining battery charge. I did find the light shining through the e-liquid gave some very nice effects.

Joyetech eGo AIO 2 Battery Performance

The Joyetech eGo AIO 2 is powered by an internal 1700mAh rechargeable battery. The specified charging time is pretty slow, taking approximately 1.5 hours to fully charge via the on board 5V/1A Type-C USB charge port. See How do I Charge the eGo AIO 2 for actual charge time.

Unable to find the output power of the eGo AIO 2 and because when it’s firing it appears to be reasonably high, I was expecting the battery to drain pretty quickly. However, I was VERY surprised, in fact I was SHOCKED at just how long the battery lasted.

On the few times I monitored the length of time the battery operated for from full charge to discharge, I achieved an impressive 18 hours of vaping. This was by no means light vaping, I was hitting the eGo AIO 2 pretty hard.

eGo AIO 2 turning red when the battery level is below 10%

Another VERY pleasant surprise was the level of detail the 7-color LED provided in terms of its ongoing remaining battery charge. Even when the eGo AIO 2 display turns red indicating 0%-10% of its remaining charge, I still achieved around 1.5hrs before it reached the low battery cut off and stopped working.

This 7-color LED, that shines through the e-liquid windows, provide a perfect indication of the remaining battery status. It illuminates during your draw and slowly fades after the fire button is released. It will also illuminate each time the top cap is fitted after filling. The different colors that correspond to the remaining battery level are as follows:

  • Red:                0% – 10% of charge
  • Purple:             10% – 25% of charge
  • Yellow:            25% – 40% of charge
  • White:              40% – 55% of charge
  • Blue:                50% – 70% of charge
  • Cyan:               70% – 85% of charge
  • Green:             85% – 100% of charge

Out of interest, I monitored the approximate vaping time between each stage of color change and have also included against these times the puff count I achieved as follows:

  • Green:             3hrs 40 minutes.  Puff count = 146
  • Cyan:               2hrs 10 minutes.  Puff count = 105
  • Blue:                2hrs 30 minutes.  Puff count = 117
  • White:              4hrs 30 minutes.  Puff count = 268
  • Yellow:            2hrs 15 minutes.  Puff count = 112
  • Purple:             1hr 15 minutes    Puff count = 49
  • Red:                1hr 40 minutes.  Puff count = 98
  • Total vape time between charges is 18 hours

Once the battery is depleted of its charge as depicted by the low voltage cut-off value, the eGo AIO 2 LED will flash red 5 times and you will no longer be able to vape.

At this stage you will need to charge the device. We’ve covered charging the eGo AIO 2 in detail in the How do I Charge the eGo AIO 2 section. The eGo AIO 2 does have pass-through so you will be able to vape while it’s being charged.

Note: Please be aware that the vaping times together with the puff count I recorded above are only a guide as my vaping style may be different from others.

Credit where credits due, the battery performance and level of detail the 7-color LED depicts is nothing short of inspiring.

How Do I Fill The eGo AIO 2?

Removing the top cap and coil from the eGo AIO 2 body

Because it’s an AIO device, its tank is inside the main body/battery section of the eGo AIO 2. To access the entry point to the tank the top cap will need to be unscrewed. The top cap has a child proof lock so press the top cap down into the eGo AIO 2 body and unscrew anti-clockwise (counter-clockwise).

Remove the top cap but note the coil will still be attached. Because the coil will have e-liquid on it, I found it easier to not remove the top cap completely so the bottom of the coil still remained in the top of the e-liquid reservoir (tank). You can if you wish place the top cap and coil on a paper towel while you’re filling the tank if you find it easier.

Max e-liquid line next to the e-liquid viewing window

There is a “Max” e-liquid level printed on the casing next to the e-liquid viewing windows so do make sure you don’t fill above this line. If you can’t see this line for any reason, only fill with e-liquid half way up the oval e-liquid window.

Fill the e-liquid no more than half way up the e-liquid viewing window

Over filling will mean when the coil/top cap are secured back into the reservoir, the mass of the coil will force the e-liquid to overflow out of the top of the tank.

Top cap fitted showing the e-liquid level inside the viewing window

Reinsert the coil/top cap into the e-liquid reservoir and screw the top cap back into position. The top cap will continue turning because it’s also the airflow ring.

Once the LED illuminates you’ll know the coil has made contact with the coil plate in the bottom of the tank. Lightly push down on the top cap and just turn an extra sixteenth of a turn to ensure it’s secure.

Note 1: Turning the top cap too tightly will stop the eGo AIO 2 from firing. The LED will flash when the fire button is pressed if it’s too tight. Unscrew slightly and try again. It really does only need a very small pinch once the LED illuminates.

Note 2: After you’ve filled the tank I found on most occasions the first few draws caused gurgling in the mouthpiece. In order to stop this, turn the eGo AIO 2 upside down and lightly tap the mouthpiece onto some tissue (paper towel) to expel the excess e-liquid from the mouthpiece.

Quick Tip: If you’re filling the tank and using a new coil for the first time, once filled, leave to stand for approx. 10-15 minutes before you start to vape. This will help saturate the wick fully in e-liquid and help prolong the life of the coil.

When and How Do I Change The eGo AIO 2 Coil?

The eGo AIO 2 uses the new BFC 0.8 ohm stainless steel Mesh coil. Unlike traditional coils where the coil is either screwed or a push fit into the base section of the tank or pod, the BFC coil is screwed into the underside of the eGo AIO 2 top cap. The coil and the top cap are then lowered down into the e-liquid reservoir in the battery/body of the eGo AIO 2.

When the coil starts to degrade after a couple of weeks use, the coil is simply discarded and a new coil fitted.

An indication of the coil degrading will show by either a loss of flavor and/or a lack of vapor. Continuing beyond this loss of flavor/vapor will finally result in a nasty burnt taste. Equally the coil could break going open or short circuit. Either way, when this happens replace the coil for a new one.

Coil unscrewed from the underside of the top cap
Coil crewed into the underside of the top cap

Unscrew the top cap using the rotating airflow control ring. Unscrew the old coil from the underside of the top cap and fit a new coil. Always make sure you prime your new coil before using it. We’ve written a guide on How to Prime a Coil so do take a look as it will help prolong the useful life of your coil.

The e-liquid in the reservoir may or may not need replacing, it depends if the e-liquid became tainted with the old coil. If in doubt, pour the e-liquid out of the reservoir and wipe the inside clean with a tissue and refill with new e-liquid.

When fitting a new coil, follow the procedure for How do I Fill the eGo AIO 2?. As you insert and screw the top cap and coil into the eGo AIO 2 body, the LED will illuminate in the color relating to the remaining charge left in the battery.

How Do I Charge The Joyetech eGo AIO 2?

When the eGo AIO 2 LED flashes red 5 times, it will require charging. The advanced kit we received includes a Type-C charging cable but if you purchase the simple kit it doesn’t come with one, so you’ll need to use a cable that you have to hand.

Type-C USB cable plugged into the charging port on the eGo AIO 2

The eGo AIO 2 has an internal 1700mAh capacity battery and charging is carried out using a USB to Type-C charging cable. Simply connect this cable into the Type-C port on the side of the eGo AIO 2 body and the other end into a suitable USB power source. The specified charging circuit of the eGo AIO 2 is 5V/1A.

Type-C USB cable plugged into the charging port on the eGo AIO 2 and the LED glowing red

When the eGo AIO 2 is placed on charge, the 7-color LED will illuminate “Red” and remain illuminated throughout the charging cycle. Once the battery becomes fully charged, the “Red” LED will extinguish.

The eGo AIO 2 does have pass-through so you can vape while it’s being charged, but bear in mind this will increase the overall charge time.

Joyetech specify that the charge time from full discharge to fully charged will take 1.5 hours. I timed the charging cycle using a 2.0A source to verify the length of time it took and was disappointed to find it took 2.5 hours. Even though the battery capacity is pretty big at 1700mAh, this is a very slow charging time.

While the eGo AIO 2 is on charge, it does remain reasonably cool to the touch but I would still recommend to ONLY charge the device on a non-flammable surface.

As with any vape device, NEVER leave it unattended whilst charging.

Joyetech eGo AIO 2 Kit Summary

The Joyetech eGo AIO 2 kit really took me by surprise. If I’m honest when I first unboxed it, I felt I’d gone back in time 6 years. It reminded me of some of the mechanical tube mods I bought at that time.

It’s not typically pretty and comes across as being very functional. However, once you start using it and appreciating all the great things about it, this little pocket rocket really comes into its own.

I did find that because I’ve been using Mechanicals, Pods, Mods and Tanks of all descriptions for nearly 10 years now, the concept of an AIO was a little strange at first. Once I took it apart to find out what it was all about, and certainly after I’d been using it for a day or two, I was hooked!

I’m very impressed with the AIO design and can see why some people swear by them. It’s very well built, very robust, feels comfortable and tactile in the hand, has an amazing display that shines through the two e-liquid windows and performs really well.

The 1700mAh internal battery is a very good sized capacity and will last you an entire day of vaping, if not more, on a single charge. The remaining battery charge level display is one of the best I’ve seen.

The two minor points I picked up on were the slow charging time and gurgling issues after refilling. But in comparison to the many, many positives these are minor, and didn’t spoil the enjoyment I had when using the eGo AIO 2.

I would definitely recommend this kit to anyone!

  1. Richard, I’ve had mine a week now and would like to help add to your review. I’ve used the original EGO AIO nearly exclusively for around 5 years, probably went through around 8-10 of them throughout that time period. I live a very active lifestyle so despite me doing my best to take care of them, life happens even though they were honestly quite rugged. So on to the changes for this one. It’s definitely a lot quieter. The original was a lot more “sputtery”. It popped and crackled a lot more and even the background hiss was louder. This is possibly due to the different coil in addition to a different drip tip that is used in this one (longer and thicker). Another difference is this one is a bit quicker to “fire”. From the time I press the button to the production of vapor is probably twice as fast or more; nearly instant on this newer model. The last noticeable change on this model is the battery life. It’s probably 30%, maybe even 40% longer on this version. That is obviously just a guess as I did not measure like you did but I know from using the others for years that this one lasts significantly longer. One thing I do slightly miss from the older model is the ability to choose the color that it is all the time but, I also can appreciate the change to the battery level being indicated by the light color instead. Overall I would definitely recommend the newer version and think the updates are worth it.

    1. Hi Chris,
      Thank you so much for taking the time and effort to share your views on the Joyetech eGo AIO 2 and how it compares against the earlier version. Sadly we didn’t own or experience the original version so didn’t have any benchmark to compare it against. I really appreciate your input and am very pleased to hear that the eGo AIO 2 is a worthy update from the original.
      Despite owning hundreds of different mods and pods, the Joyetech eGo AIO 2 was the first true AIO device I’ve used and can say I was really impressed with it and still really enjoy using it.
      Your comments are very helpful Chris and I thank you again.

  2. Wow. That’s what I call a review, my friend. I’ve sat through many lectures during several years of “higher learning” that would have come up short. I came here looking for any reason my AIO 2 was burnt right out of the blister. I was tightening too much.

    I’ve used AIOs since I began vaping and had no intentions of giving up, but I’ll admit I was growing discouraged. I bought the 10th Anniversary Edition and had no luck with it, perhaps for the same reason. I knew all the tips and tricks for my standard AIO, or so I thought, but this is a bigger issue with this new model.

    Thanks for the helpful information and the time and effort it took to write this (rare things).

    1. Thanks so much for responding to my review and for your kind words, it’s really appreciated. I’m pleased to hear it was helpful. Comments like yours makes the time and effort in doing these reviews worth while.
      Over-tightening the top section did stump me for a while as it seemed the natural thing to do to stop it from leaking. Once I tightened it till the AIO 2 detected the coil everything worked really well.
      Thank you again friend.

        1. Hi Chris,
          MyVapor are still in business and have stores in various countries. I was talking with them only a week ago. A company we’ve been using for a while now, have the Joyetech AIO 2 in stock for £16.99. Hope this helps.

          1. Thank you for the suggestion! MyVaporUS’s online store that you have linked is OOB though. Try adding something to cart or navigating the site. The link works but as soon as you change pages they have their “Goodbye” message.

          2. Hi Chris,
            Thanks for verifying this, I’m getting the same message. I’m not sure which of their USA stores are closing as it’s difficult to find out from their website. I will try and find out anymore information and let you know. Thanks again.
