Okino C100 Pod Kit Review | A DTL/RDL Little Gem With Massive Performance

Richard WinterPod Vapes Leave a Comment

Today we’re taking a look at and reviewing the Okino C100 Pod Kit, a tube style DTL dual activated open pod system (refillable) with replaceable coils and an 800mAh internal rechargeable battery.

Okino C100 Pod Kit in Blue

If you’ve not heard of Okino before it’s because this is a new brand and the Okino C100 Pod is their first device under this name. Don’t panic; Okino is a sub-brand of Innokin and shares their R&D team and supply chain so you have the assurance of the usual Innokin quality.

Life is never straightforward and I’m in two minds whether to call this an Innokin Okino C100 or just plain Okino C100. For the sake of clarity I will omit Innokin as their branding is not on the device although the packaging states “Powered by Innokin” and “Manufactured by Innokin”.

Well, that’s that out of the way so let’s get on with the review of the Okino C100 Pod Kit.


Front View Of Blue Okino C100 Pod Kit and Reverse View of Red Okino C100 Pod Kit

The Okino C100 Pod Kit is a Direct-To-Lung (DTL) or arguably a Restricted Direct To Lung (RDL) tube style pod device and powered by an internal 800mAh rechargeable battery. There is no adjustable wattage control but the Okino C100 auto detects the coil resistance in the pod, sets the wattage accordingly and the power is then derived directly from the battery.

Dual activation is a feature on this kit so you have the option of auto draw or fire button control. It doesn’t have any variable airflow control although the fixed airflow does provide a very good unrestrictive DTL vape draw.

Included in the kit are either a 2ml or 4ml pod (depending upon your location) and one RDL 0.4 ohm coil. An additional 0.6 ohm RDL coil is available but you’ll have to purchase this separately. There is no charging cable included but the Type-C charging port is specified as 5V/1A so any standard Type-C to USB cable will suffice.

Multi-Colored LED Ring around the Base of the Okino C100 Pod Kit

The User Interface (UI) consists of a multi-colored ring around the base of the Okino C100 that provides the battery status during usage and while charging. It also provides a visual indication of the included safety features. In addition, you can select this colored ring to flash and cycle in the color spectrum or alternatively it can be turned off.

The top fitted pod has a concealed side fill port and a duck bill style integrated mouthpiece. It’s made out of semi-opaque tinted PCTG material and is magnetically secured to the Okino C100 body.

Okino C100 Pod Kit Size comparison against a 21700 Battery

Its design and shape is a reasonably stubby tube style device, not much bigger than a 21700 battery. The overall height of the Okino C100 is 99mm (including the pod) by 25mm in diameter with a combined weight of 48.2 grams, making this very lightweight and portable.

There are 6 different colors in the Okino C100 range; Black, Blue, Green, Grey, Purple and Red with the colored surface finish a semi-matte. We received two colors; Blue and Red which you will see in the photos throughout this review.

Strangely enough, on the Okinolabs website they show a photo of 11 different color devices but looking at Innokin’s website they only show 6 colors. A quick search on other websites again shows 6 colors.

That gives you an overview of the Okino C100 but do carry on reading where we explore the finer detail and look into the workings and performance of the Okino C100 Pod kit.

I would like to thank Alisa at Innokin for sending me two Okino C100 Pod kits together with a pack each of the 0.4 ohm and 0.6 ohm coils to review. As always this review is completely unbiased and is my honest opinion of my findings while using and reviewing the supplied kit.

Okino C100 Pod Kit Design and Appearance

Okino C100 Body/Battery

Front View of the Okino C100 showing the Fire Button

The Okino C100 is a minimalistic yet solid performer, delivering an output power derived from the direct output voltage of the internal battery. It auto detects the resistance of the fitted coil in the pod which sets the wattage accordingly.

Because of its simplicity, there is no variable wattage adjustment and no variable airflow control.

Don’t let this put you off though, the intensity of the draw throughout the discharge cycle of the battery is very good and it produces plenty of flavor and immense vapor from the included coil. The vaping style is also a very good RDL/DTL draw, one of the best I’ve experienced, especially from a small pod device.

Reverse View of the Okino C100 showing the Type-C 5V/1A charging Port

An 800mAh capacity internal rechargeable battery is the power source of the Okino C100 and is charged via the Type-C USB port, located on the reverse side to the fire button and is specified as 5V/1A. Full charge takes approximately 90 minutes and it also has pass-through so you can vape while it’s being charged.

The Okino C100 is a dual activation device; being both auto draw and fire button activated. You cannot lock the fire button to only auto draw, therefore both functions are always active. The circular fire button measures 8mm in diameter and sits within an outer shroud. This button has a positive click feel with no button rattle. Auto draw is also very responsive.

A large multi-color changing LED ring, positioned around the base of the Okino C100 provides the visual indication of the remaining battery charge during each draw, the status of the battery while it’s being charged and shows the multiple levels of protection (more on this in the Functionality section).

Base View of the Okino C100 Battery/Body

This color changing LED ring can be selected to strobe on and off providing a continuous multi-color light sequence by pressing the fire button twice. Surprisingly if you select this function the lighting effect remains illuminated, it doesn’t have a time out.

I did notice that once the battery reaches approximately 30% of its remaining charge the lighting effect cannot be switched on.

The Okino C100 is constructed out of lightweight material, which I assume is plastic and measures 80mm tall (99mm including the pod) by 25mm in diameter. This is a compact and very lightweight device, weighing in at only 48 grams, but despite this it does feel very robust.

It’s a tube shape design with a flat base so there is no problem with it falling over when stood upright. The whole surface area is smooth with the exception of the very slightly raised fire button and the Type-C charging port which is slightly recessed into the Okino C100 body.

Front View of the Okino C100 showing the Fire Button and the U Shaped Cut-outs around the Pod Recess

At the top of the Okino C100 is the 12.5mm deep pod recess. The perimeter of this recess is circular but has two “U” shaped cut-out channels which locate with the two similar tags on the pod so it can be fitted one of two ways.

Pod Recess of the Okino C100 showing the magnets, coil contacts, auto draw sensor and the absorbent pad

In this recess are 2 small circular magnets that are located within a circular black plastic shroud around its perimeter which locate to the matching magnets on the bottom of the pod. Positioned slightly lower than these magnets are 2 gold plated spring loaded coil contact pins and the black auto draw control sensor.

As we all know, the majority of pods do suffer from condensation or slight e-liquid leakage from the base of the pod. To combat this and help prevent e-liquid seeping into the internal workings of the device, Okino have included 5 absorbent cotton pads in the kit that sit (one at a time of course) within the pod recess to soak up any excess e-liquid.

This is a very simple but very effective solution to this common problem.

Okino branding on the device includes their name “OKINO” screen printed on the lower section of the body below the Type-C charging port and “OK” screen printed on the other side below the fire button. The usual CE markings and the “800mAh” battery capacity are printed on the flat base of the Okino C100 body.

With regards to safety features, the on-board chip provides the following levels of protection:

  • Overtime:- 10 seconds cut-off
  • No Load (o/c):- No coil detected (>3.5 ohms)
  • Overcharge:- Cuts off at 100% charge
  • Over Discharge:- Device will shut down
  • Over Temperature
  • Short-Circuit: S/C or Low resistance detected (<0.3 ohms)

The entire hard plastic frame is colored with a semi-matte finish and there are 6 different body colors available in the Okino C100 range:

  • Black
  • Blue
  • Green
  • Grey
  • Purple
  • Red

As I mentioned in the Overview, the number of colors available is a little confusing so I’ve stuck with the color range that is being sold in the shops.

Okino C100 Pod

The Okino C100 pod accepts the OK series of push fit coils and has a 2ml (TPD) or 4ml (standard) e-liquid capacity. It’s constructed out of semi-opaque black tinted PCTG material and has a concealed side filling e-liquid port.

Okino C100 Pod View 1

Despite the pod being semi-opaque, the black tint is quite dark so checking the level of e-liquid in the pod does require viewing in light conditions.

Its dimensions are 32mm tall (18.5mm when fitted) by 25mm in diameter. The mouthpiece is a duck bill shape design and integrated into the pod casing.

At its tip, the mouthpiece is 16mm wide by 7mm deep with an 8mm oval opening that leads down to an internal circular chimney and onto the top of the coil.

To gain access to the fill port you have to remove the pod from the Okino C100 body. Once removed, the fill port is concealed by a flush fitting black silicone rubber flap. This silicone rubber flap has an arrow indented into it showing which end has to be lifted away to release the rubber bung that seals the filling port.

The other end of the rubber flap remains attached to the pod by a small rubber spike so won’t get misplaced. This flap can be swivelled around giving greater access to the fill port.

Once the rubber filling port flap is opened, the e-liquid fill port is a pretty decent sized semi-oval opening measuring 5mm so is big enough to accept short stubby e-liquid tip bottles.

On the bottom of the pod are 2 circular magnets that secure the pod into the Okino C100 pod recess and the opening for the OK coil to be inserted. The OK coils are a push fit type and have a single O-ring around the top of the coil housing and another single O-ring around its base to ensure an airtight seal when fitted.

Important: The base plate of the coil has two small cut-outs which must align with the two circular magnets so when fitted, the base of the coil sits flush with the level of the magnets and the base of the pod. Failure to align means the coil won’t sit flush and won’t operate correctly.

Inserting the pod is straightforward enough, simply offer the bottom of the pod into the top recess of the Okino C100 and align the “U” shaped cut-outs in the C100 with the corresponding tags on the pod. It will then slide into the recess and be locked into place by the two circular magnets.

When the pod is inserted the multi-color LED ring around the base of the Okino C100 will flash once in the color corresponding to the remaining battery charge to indicate the pod has made contact. Removing the pod is carried out by grasping the pod body and lifting away from the Okino C100 body.

Close Up View of the Max E-liquid level marker on the C100 pod

Branding on the pod is non-existent with the exception of a “Max” e-liquid level marker on the opposite side to the fill port opening and the “CE” marking. There is no company logo or name.

Strangely enough, the “Max” marking is only half way up the pod which I did find a little confusing. When the coil is fitted, this “Max” level line sits level with the center of the coil wicking ports which really is only about 1/3rd full.

I would have expected the e-liquid level to sit above the top of the wicking ports of the coil! I do wonder if they mean “Min” level?

Okino C100 Functionality

The Okino C100, despite having limited functionality really does produce a great vape. There is no variable wattage or pre-set power levels and no airflow control but to be honest, it doesn’t need them.

Power control is derived from the automatic coil recognition of the fitted coil in the pod and the voltage applied to the coil is taken from the direct battery voltage output. The Okino C100 is dual activated meaning it’s both auto draw and fire button controlled.

A user interface display (UI) comes in the form of a multi-colored transparent LED ring around the base of the Okino C100 which indicators the status of the battery during use and while charging and also display each of the safety prompts.

This LED ring can be controlled to cycle and flash in a full spectrum of colors, which although providing a fun visual display, doesn’t have a time out period so will continue to flash until such time the battery depletes or you turn it off.

Operation of the Okino C100 is carried out using a sequence of clicks of the firing button as follows:

  • Fire button pressed 3 times turns the device on or off
  • Fire button pressed 2 times will switch the LED ring on or off

When switching on the device, the LED ring will flash from Red to Green then Blue and extinguish. Switching off the device will cause the LED to flash twice in the color corresponding to the remaining battery charge:

  • Red LED:        <10%
  • Blue LED:        10% – 30% (see Note 2)
  • Green LED:     >30% (see Note 2)

Note 2: The actual color sequence when using the Okino C100 is different from the information in the user manual that I’ve detailed above. In reality, the remaining battery status indications of the Blue and Green are reversed. Also the percentages against each color don’t stack up with the times I recorded during use. See the Battery Performance section for addition information on the recorded times.

The Okino C100 LED will display different colors and sequences to highlight individual functions and the safety parameters as follows:

  • While Charging:                      Red LED illuminated at <90% of charge
  •                                                 Blue LED illuminated at >90% of charge
  •                                                 LED extinguished indicating Full Charge
  • While Vaping:                          LED will illuminate (color determined by battery level)
  •                                                 Red = <10% (see Note 2 above)
  •                                                 Blue = 10% – 30% (see Note 2 above)
  •                                                 Green = >30%
  • Low Voltage Protection:          Red LED flashes 8 times
  • Short Circuit Protection:          Red LED illuminates for 5 seconds
  • Over-Time Protection:             LED flashes 10 times in the color of the battery level
  • Low Coil Resistance:              Red LED Illuminates for 5 seconds
  • High Coil Resistance:              Blue LED flashes 5 times
  • PCB High Temp:                     Red LED flashes 3 times + 3 times
  • Pod Inserted:                           LED flashes once
  • Pod Removed:                        No indication

Lastly, the fire button cannot be locked so is always operational unless the device is switched off. While not a game changer, be aware that if this is placed in your pocket or in a handbag there is always the chance of it firing inadvertently.

Okino C100 Performance

Okino OK RDL 0.4ohm R2 Coils and packaging
Okino OK RDL 0.6ohm R1 Coils and packaging

Only 1 coil is supplied in the Okino C100 pod kit; an RDL OK 0.4 ohm R2 mesh coil. Innokin kindly sent us a pack of these 3coils together with a pack of the RDL OK 0.6 ohm R1 coils so we will included the description and performance of these in this section.

Okino OK RDL 0.4ohm R2 Coil and OK RDL 0.6ohm R1 coil

From looking at the Okinolabs website, they specify that the OK coils will last up to 3x longer than other conventional coils. Their literature suggests that each coil is good for between 15-20 refills, which equates to approx. 60ml – 80ml of e-liquid.

As always, when filling the pod for the first time, prime your coils before using them which will help prolong their life. Drip a few drops of e-liquid into the wicking ports of the coil and then fill the pod and leave to stand for 10-15 minutes.

RDL OK 0.4 ohm Mesh Coil (R2 with Red O-rings)

Okino OK RDL 0.4ohm coil with Red O-rings

Okino specify the operating wattage of this coil is 22.5W.

Straight from the first puff, the flavor of my e-liquid was instantly recognized and gave me a pure clean taste. After a few draws, the flavor increased as the coil began to bed in.

What really surprised me was the immense amount of vapor that the coil produced. For me it was definitely a DTL draw and from experience this matched some of my high powered RTA tanks.

I’ve cycled different flavors with different PG/VG ratios through the pod/coil all with really nice results.

RDL OK 0.6 ohm Mesh Coil (R1 with Blue O-rings)

Okino OK RDL 0.6ohm coil with Blue O-rings

Okino specify the operating wattage of this coil is 18W.

Performance wise, the 0.6 ohm R1 coil was equally as impressive as the 0.4 ohm R2 coil.

The intensity of the vape was not as strong from this coil but then that’s expected as the operating wattage is approx. 5 watts lower than the 0.4 ohm coil.

Flavor was good and picked out each flavor that was cycled through the pod/coil. Vapor was still really impressive. Draw wise I felt it was very slightly restricted so mimicked a RDL vape style.

Any Leaks?

In my experience there are very few pods (if any) that don’t suffer from the occasional e-liquid seepage. Unfortunately this seems to be inherent with pods but in a lot of cases it’s just condensation from the heating and cooling process.

Okino C100 showing the pod recess with New and Used absorbent cotton pad

Okinolabs have come up with a solution to this problem and incorporated these little absorbent cotton pads that fit in the pod recess and interface between the base of the recess and the bottom of the pod/coil.

While it doesn’t stop the buildup of e-liquid around the pod base, the pad will absorb any excess e-liquid and stop it from seeping down through the coil contact pins into the mod body and damaging the device.

Throughout the 2-3 weeks I’ve been using the Okino C100, the pad has absorbed the e-liquid but has definitely stopped the e-liquid progressing into the mod.


Because there is no airflow adjustment on the Okino C100, you’re reliant on the fixed airflow that the device has been designed to work at.

The airflow in my opinion produces a really good DTL draw on the 0.4 ohm R2 coil and an ever so slightly restrictive draw (RDL) when using the 0.6 ohm R1 coil.

With non-adjustable airflow pods, small pins holes usually provide the air intake but with this one these are not present. While it’s not apparent, the air intake appears to come from the slight gaps from between the pod and the top of the Okino C100 pod recess.

Auto Draw

Auto draw was faultless. It’s very responsive and worked really well, so much so I vaped using this method 95% of the time. Because it’s a DTL draw, you do have to vape it like this (no tiny draws) otherwise the auto draw won’t activate.

Performance Summary

Side View of the Okino OK Series R1 and R2 coils

Both the included 0.4 ohm R2 coil and the separately purchased 0.6 ohm R1 coil were very impressive. Flavor was good but where these coils really shine was the incredible vapor. Even a quick 1-2 second draw produces very dense clouds.

There didn’t appear to be any difference with the draw or the performance when comparing auto draw and fire button activation. Equally, the intensity of the vape remained constant throughout the discharge cycle of the battery.

Overall, I couldn’t fault the performance. Taking into account the simplicity on the Okino C100, it has to be one of the best DTL pods I’ve come across.

Okino C100 Battery Performance

The Okino C100 is powered by an internal 800mAh rechargeable battery. Although this is only an average sized capacity battery and considering the output power when using the 0.4 ohm coil is 22.5W, I was achieving around 6 hours vaping from a fully charged battery.

Front and Back views of the Okino C100 Pod Kit

This time will vary depending on the resistance of the coil you’re using and your vaping style i.e. duration and frequency of your draw.

Charging time will take approximately 90 minutes to fully charge via the on board Type-C USB port with the added benefit it has “pass-thru” so you can vape while it’s on charge.

During vaping (when you draw on the device), the multi-color changing LED will illuminate in the color corresponding to the level of charge left in the battery as follows:

  • Green              – >30%- – Full charge (see Note 3)
  • Blue                 – 10% – 30% of charge (see Note 3)
  • Red                 – <10% of remaining charge
  • Flashing Red   – Low voltage cut-off

Note 3. The battery level indications on the multi-color LED ring are in fact different from the description in the user manual that I’ve detailed above. While using the Okino C100, full charge starts off with the “Blue” color. After vaping on it for a few hours, the LED ring changes color to “Green”.

Continuing to vape for another hour or so the multi-color LED will then change to “Red”. Once the LED is showing red when you vape, I found that I was getting around another 1 hour of usage before the battery cut out and started flashing red 8 times.

Once the LED flashes red 8 times, you will no longer be able to vape and will have to re-charge the battery.

I did an experiment to gauge the length of time the multi-colored LED took to change to each color level during normal vaping. The times before switching to each color were fairly repeatable and I have listed these approximate times below:

  • Blue – Green                                      – 3 hours 15 minutes
  • Green – Red                                       – 1 hours 40 minutes
  • Red – Flashing (discharged)                        – 50 minutes

These times were monitored using the 0.4 ohm coil. I didn’t repeat this test for the other resistance coil but because of the lower power levels, these times should increase.

You can see from the above recorded times for each color change that the actual times don’t equate to the percentage (%) values in the user manual. A more realistic time would be approximately:

  • Blue                 – >45%- – Full charge
  • Green              – 15% – 45% of charge)
  • Red                 – <15% of remaining charge
  • Flashing Red   – Low voltage cut-off

How do I Fill the Okino C100 Pod?

The design of the pod, being a concealed side fill, means you will have to remove it from the Okino C100 body to fill with e-liquid.

Okino C100 Pod with the silicone rubber stopper turned round showing the fill port opening

Once the pod is removed, the black silicone rubber flap will be visible on the curved round edge of the pod. This rubber flap sits flush against the pod casing and has a small arrow indented into the rubber to indicate which end of the flap needs to be lifted up and away.

Gently pull this end of the flap upwards so the bung comes away to reveal the semi-oval fill port. The other end of the rubber seal is secured to the pod so it won’t get misplaced. If needed, you can swivel this flap out the way of the oval opening.

Tilt the pod on its side, fill the pod up with your e-liquid and replace the black silicone rubber seal ensuring the bung is securely fitted in the fill port opening. The semi-oval fill port is a reasonable size (5mm) so will accept short stubby tip e-liquid bottles.

How do i fill the Okino C100 pod

There is a “Max” fill line on the opposite side to the fill port but I’m still unsure why this line is as low as it is. To me it would make sense if the line was a “Min” level.

Re-insert the pod into the Okino C100 body pod recess, making sure the extended lugs on the pod line up with the “U” cut-outs in the C100 body and ensure it’s held securely by the magnets.

Quick Tip: If you are filling the pod for the first time after fitting a new coil, do ensure you prime the coil first by dripping a few drops of e-liquid into the wicking ports. 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 in the pod.

How do I Change the Coil in the Okino C100 Pod?

If the coil in your pod is showing signs of failing with a loss of flavor or vapor, or worst case the e-liquid tastes burnt then it’s time to change your coil. Equally if the Okino C100 indicates a short or open circuit coil via the LED prompt, the coil will have to be discarded and replaced.

Coil being removed from the base of the Okino C100 pod

The pod will have to be removed from the Okino C100 body first to gain access to the bottom of the pod.

Once the pod has been detached, simply pull the coil out from the bottom of the pod. If you have e-liquid in the pod, turn the pod upside down and place your thumb or finger over the mouthpiece opening before you remove the coil. This will help keep e-liquid spillages to a minimum.

Coil fitted in the base of the Okino C100 pod

Important: The bottom flat plate on the coil has two “U” shaped cut-outs. These two cut-outs need to align with the position of the two circular magnets. When the coil is fitted, the bottom plate of the coil MUST sit flat and flush against the bottom of the pod casing.

As above, slowly push your new coil into the opening in the base of the pod and press it fully home. Make sure the “U” shaped cut-outs in the base of the coil aligns with the magnet sides and sits flush with the base of the pod. If the base of the coil is sitting proud of the pod base, turn the coil round so the cut-outs align.

Do ensure that your new coil is primed by dripping a few drops of e-liquid in the wicking ports. Fill the pod with your e-liquid and leave to stand for 15 minutes so the e-liquid fully saturates the wick. See our guide on Prolonging the Life of your Coil.

Before you refit the pod into the pod recess, check that the absorbent cotton pad is still in good condition.

How do I Charge the Okino C100?

When you first receive your Okino C100 Pod Kit it does come with a nominal charge. We do recommend to fully charging the device before you first use it.

During use, once the multi-colored LED ring on the bottom of the C100 starts flashing red 8 times, highlighting that the battery has reached its low battery cut-off, you will need to place the Okino C100 on charge.

As we’ve mentioned, the kit doesn’t come with a charging cable. Most Type-C cables that you use for your phones or tablet will work fine. Plug the cable into the Type-C USB port on the reverse side of the Okino C100. Connect the other end into a suitable power source (typically 5V/1A).

When the Okino C100 is first placed on charge the LED will flash red, blue then green after which it will remain illuminated in red. It will stay showing red until the charge reaches 90% of its full charge at which point the LED will turn blue.

Once full charge is completed, the LED will extinguish. At this point, remove the power source and you’re ready to vape again.

For reference, we timed the length of time it took for the LED to change color at each stage of charging:

  • Red for 48 minutes
  • Blue for 42 minutes
  • Full charge in 90 minutes (1hr 30 minutes)

Charging time takes approximately 90 minutes to fully charge the battery. Do note the Okino C100 does have a “pass-through” facility therefore you will be able to charge and vape at the same time.

I did observe that while the Okino C100 was being charged, the case was slightly warm to the touch. However, I strongly advise to always charge this, and any other device for that matter, on a non-flammable surface.

As always, NEVER leave your vape device unattended while on charge.

Okino C100 Pod Kit Price

The Okino C100 is a simple no fuss pod kit with the benefits of having replaceable coils and being refillable. What makes this pod different from the majority of others is the DTL/RDL draw. Performance from the included 0.4 ohm coil plus the 0.6 ohm coil we additionally received really did produce immense vapor.

It’s currently retailing around the $17 – $20 figure so if DTL/RDL vaping is your style then really is a good one.

Okino C100 A1 Pod Kit Summary

Red and blue Okino C100 kits

The Okino C100 won’t win any medals for its looks but where this pod comes into its own is the performance in terms of the draw and vapor. Flavor from the coils was good but the vapor was insane.

I always get excited to see a pod that takes replaceable coils and both the 0.4 ohm and 0.6 ohm coils worked really well. Yes the pod does leave a slight e-liquid seepage in the recess but the absorbent cotton pads do a good job stopping the e-liquid causing any problems.

Blue Okino C100 kit

The Okino C100 is simple in terms of no variable wattage or variable airflow control BUT it really didn’t matter. Being able to just pick this up and straight away have a really good vape meant a lot. Coil longevity so far looks very good too.

My only two very minor points that I feel would enhance the experience of the Okino C100 would be to make the tint on the pod lighter so you can see the e-liquid level easier. Secondly, the strobe effect LED ring would be more effective if it came on when you draw on the pod and went off automatically after a few seconds.

Apart from this, it’s well built, very lightweight, has a decent sized battery AND gives a really excellent vape. It charges pretty quickly, has pass-thru and gives many hours of vaping on a single charge.
