Geekvape Aegis X 200W Kit With Cerberus Sub Ohm Tank Review

The Geekvape Aegis X 200W mod kit, paired with the Cerberus sub ohm tank, is a much improved upgrade from the ever popular Aegis Legend. Following in Geekvape’s usual vein of styling, the Aegis X is rubberized and IP67 rated meaning it’s dust-proof, shock-proof and water-proof.

It’s powered by dual external 18650 batteries incorporating the advanced AS 2.0 chip which provides the control, functionality and a host of safety features. The Aegis X fires up to 200W, providing modes for Power (W), Temperature Control (TC), Variable Power Curve (VPC) and Bypass.

The display really is something else, a massive 2.4 inch color screen, something we’ve not seen in the Aegis series of mods before. There’s also a function we’ve not come across before; ‘ABB’ (Advanced Battery Balancing). Geekvape claim this improves the draw on the individual batteries, maintaining a more balanced drain on each battery.

There are 8 different colors in the Aegis X 200W range; black, silver, red, gold, orange, green, gunmetal and rainbow. The main body of the Aegis X is black silicone rubber with the zinc alloy band matching the colors specified above.

The Cerberus sub ohm tank also comes color matched to the Aegis X mod. The e-liquid capacity of the Cerberus is 2ml (EU version), 4ml standard, or a 5.5ml bubble glass addition.

Overall, this really is a solid, powerful and robust piece of kit, something we’ve come to expect from the quality and name of Geekvape. Read on and find out just what we thought.

I would like to thank the guys at NewVaping for sending us the Aegis X 200W Kit with the Cerberus sub ohm tank. As always this review is completely unbiased and is my honest opinion on the supplied kit. We may receive a small commission through any affiliate links but at no extra cost to you.

Geekvape Aegis X 200W | Design and Appearance


The Aegis X 200W is a variable wattage (5W-200W) and temperature control (100-315oC/200-600oF) mod. As a bonus it also includes variable power curve mode and a bypass mode.

As we’ve come to expect from Geekvape, the Aegis X is IP67 rated, ensuring dust-proof, shock-proof and water-proof compliance. Its power source is provided by dual external 18650 batteries and the control is achieved by the updated AS 2.0 chip set.

Aegis X Big Screen View

Made out of zinc alloy, the majority of the external surfaces are covered in a thick black silicone rubber coating. Around one side of the Aegis X mod is the now famous Geekvape colored banding with the faux leather inlay.

The other side houses the massive 2.4 inch colored OLED display. This screen is a beauty! Very clear and very crisp, it shows coil resistance, volts, amps, a puff counter, wattage or temperature and the battery status of each individual battery.

The screen can also be adjusted to display 3 different styles in 5 different colors and the brightness of the screen is adjustable between 0 and 100%.

Firing the Aegis X is carried out by a fairly large bevelled button on the front above the two smaller +/- bevelled buttons. The response and feel of the buttons is very positive with no button rattle at all.

On the top of the mod is the centralized gold plated spring loaded 510 threaded connector and the black silicone rubber plug that covers the micro USB charging port. Firmware is upgradeable via this micro USB port too.

On the bottom of the Aegis X mod is the recessed spring loaded battery cover. To open, slide the cover back releasing its catch to reveal the dual battery compartment. Polarity indicators are included inside the body and on the battery door.

Aegis X Battery Door View

To close the battery door, press the battery cover back down and push the battery latch plate to lock the cover. Not the easiest of operations, but once you’ve done it a couple of times it does become second nature. A single row of 5 small holes are located on the bottom of the battery cover to allow for any possible battery venting issues.

Geekvape’s branding is kept to a minimum. Their name is printed into the top of the OLED display and the words ‘AEGIS’ are printed in white underneath the +/- buttons.

Accessing the menu structure is achieved using the fire button and the +/- buttons (more on this later in the functionality section).

With regards to safety features it has the following:

  • 10s timeout
  • Low battery and weak battery cut-off
  • No coil detected
  • High temperature “Overheat” cut-off
  • Short circuit and high/low resistance cut-off

Overall, the Aegis X feels very solid and extremely well built. It oozes quality and despite its size, feels comfortable to hold. The ruggedness of the design certainly means it’ll withstand the toughest of challenges.

Geekvape Cerberus Sub Ohm Tank | Design and Appearance


The Cerberus sub ohm tank has been around for a couple of years now but is still a worthy contender. It’s 25mm wide with a 2ml e-liquid capacity (EU version). There is a 4ml and a 5.5ml bubble glass version which I would opt for to negate the need for filling so frequently.

This tank is a top fill design with a difference. It’s not threaded but uses a quarter turn operation. Two notches on the underside of the top cap fit into two flat indents on the main body. When connected, the notches slot into a channel and lock into place once it’s turned. The large O-ring on the underside of the top cap provides an airtight seal.

Cerberus Tank Fill View

Once the top cap is removed, there are two decent sized slots to allow for a large tip e-liquid bottle to be used. Filling can be carried out using either slot.

Airflow is achieved by a variable dual slot air flow control ring at the bottom of the tank. Again this is a quarter turn from fully open to fully closed.

Each tank is color matched to the color of the mod, with a black, low profile delrin 810 drip tip.

Cerberus Tank Breakdown

The word “Cerberus” is discreetly printed on the top cap of the tank. 

The overall height of the tank, including the low profile 810 drip tip and excluding the 510 threaded connector is 35mm. One point worth mentioning, the 510 threaded connector does have a pretty decent protruding center pin (always handy for those hybrid mods).

Two coils are supplied with the Aegis X 200W kit but unfortunately both are the same type, the Mesh X1 KA1 0.2 ohm coil. Geekvape specify the wattage for this coil is between 30W–90W, but best at 60W-80W. Interestingly, the Vaporesso GT CCELL, GT mesh and the Smok Baby coils will also fit this tank.

Geekvape Aegis X 200W Mod | Functionality


The Aegis X is fully loaded with features. Power (wattage) mode with the option of soft, normal and powerful pre-heat options. Temperature control mode which includes SS, NI200, TI and TCR. When in TCR mode you can adjust the temperature coefficient for any value you wish. There are also modes for Variable Power Curve (VPC) and Bypass. 

A really good feature I found very useful are the 4 memory modes. These can be programmed with different modes and once you’ve set them up, you simply switch between them with your pre-set options being recalled.

Gaining access to the menu functions of the Aegis X is carried out by the fire button and the +/- buttons. It’s worth having a play around with the menu options to familiarize yourself with the structure of them.

Although the manual touches on the menu settings, it’s a bit vague to say the least and it didn’t come all that easy to me. I would recommend before first use having a good play with the different menus before you fit the tank.

Turning the Aegis X on or off is carried out by pressing the fire button 5 times in quick succession. This will bring up the main screen display that shows the mode you are in, the coil resistance, volts, amps, puff counter, wattage or temperature and battery status of each individual battery.

Locking and unlocking the device is carried out by pressing the +/- buttons simultaneously for 3 seconds.

Selecting the screen brightness is carried out by pressing the fire button and the + or – button. The screen brightness is adjustable between 0 and 100%.

Stealth mode is available by holding down the fire button plus both +/- buttons for 3 seconds. The screen will go blank and you can still vape with the settings you had. Pressing all 3 buttons for 3 seconds again will bring you back out of stealth mode.

Menu 1

To get into the first menu, press the fire button 3 times in quick succession. Straight away, press either the +/- buttons to scroll through the 4 different memory modes, M1, M2, M3 and M4. These different modes can be programmed for any of the functions available and recalled at the press of a button.

To leave this menu, simply wait 5 seconds and it will return to the main screen.

Menu 1A

While in the first menu (3 fire button clicks), instead of pressing the +/- buttons like we did above, press the fire button. This will scroll through all the available options for configuring your mod for whatever memory mode you are in.

By pressing the fire button, this will scroll through the top level menus highlighting the following parameters. When you’re in the highlighted parameter, you can then use the +/- buttons to alter the individual settings.

  • Memory mode: M1, M2, M3 and M4
  • Vape Mode: Power, VPC, Bypass,  SS/TCR 0105, NI/TCR 0690, TI/TCR 0420 and TCR/TCR

While scrolling through the menus, depending on what function you have selected, a sub menu will be highlighted.

  • Power mode: Standard, Powerful, Soft
  • VPC: Time 0.5 seconds to 1.2 seconds
  • TCR: TCR 0010 to TCR 5000

Also, again depending on your vape mode setting, while scrolling through the settings, you have access to the following:

  • Coil: Select Lock or Unlock
  • Watts: Adjustable in Temperature mode
  • Puff: Resets the puff counter
  • Volts: Displays the voltage
  • Amps: Displays the current
Variable Power Curve

The only other fiddly setting is VPC mode. After selecting VPC, press the fire button to highlight the “Time” heading. Set the time you want the first power level to run for. Press the fire button again and it will scroll to the wattage heading. Use the +/- buttons to select the wattage you want to set.

Press the fire button again and it will take you to the next power level. Adjust as appropriate till all the power curves have been completed.

Menu 2

This menu gets you into the fancy options, namely the ‘Theme’ and ‘Color’ options along with a few other settings as well.

Aegis X Menu 2
  • Auto: On/Off. Detects the coil you’re using and automatically sets the wattage
  • Theme: Selects between 3 different screens
  • Color: Selects 5 different screen colors
  • Version: Current firmware version and date
  • ABB: On/Off. Automatic Battery Balancing
  • Reset: Resets to factory settings

To get to this menu, press the fire button 3 times, then straight after, press and hold down the +/- buttons for 3 seconds. Use the +/- buttons to scroll through the different options. Once an option is highlighted, press the fire button to get you into that screen menu.

From that menu, use the + or – buttons to select the options in that menu, i.e. different themes or different colors etc.

Unfortunately, the user manual doesn’t really tell you much about the different settings and what they do. To give a little insight to what the different options mean, we’ve included a brief description below.

Power Mode

Selectable as either standard, powerful or soft. Standard will fire at whatever wattage you’ve selected. Soft will give a slow ramp-up to your set wattage. Powerful will act like a pre-heat function, initially firing at a higher wattage then dropping down to your selected wattage.

Variable Temperature Control (TC)

Select either Stainless Steel 316L (SS), Titanium (Ti), Nickel 200 (Ni) or Temperature Coefficient Resistance (TCR). The 3 pre-set wires have fixed pre-programmed values, whereas TCR allows you to set the TCR value when using other temperature heating wires. The variable range for TCR is 0010 to 5000.

Variable Power Curve (VPC)

This function will allow you to specify different wattages that can be applied to your coil over a vape cycle to fully customize your vaping experience. There are 6 variable wattage settings, each adjustable from 5W to 200W with each setting being adjustable over a time range of 0.5 seconds to 1.2 seconds.

If you would like to further understand how VPC works, take a look at our VPC Explained guide.

Bypass Mode (BP)

Provides a direct output voltage from the battery, simulating the feel and style of a Mech mod.

Automatic Battery Balancing (ABB)

Selecting this option will automatically balance the levels of each of the batteries. It will draw more charge from the more powerful battery to self-level the two batteries together.

Geekvape Cerberus Sub Ohm Tank | Performance


0.2 Ohm Mesh Coil (X1 KA1)

Geekvape specify the wattage range is between 30-90W. Best at 60-80W.

Cerberus X1 Coil

After filling and priming the coil with my favorite juice (Thug Juice – 50/50 at 3mg), I set the wattage to a pretty low 20W to allow the coil to slowly bed in. After a few draws with very minimal vapor and flavor, I increased the wattage to 25W.

The flavor and vapor began to kick in but the coil definitely still needed more power. Increasing the wattage to 30W, the vapor kicked in giving a slow draw with plenty of vapor.

The flavor sadly was not very pronounced and I was getting that new coil taste. It took a good tankful of e-liquid before that taste went and the flavor came through really crisp.

Increasing the wattage to 40W certainly produced a harder hit improving the flavor and vapor no end.

Gradually increasing the wattage in 10W increments, all the way to 80W was amazing. Flavor and vapor was intense but too powerful for me. Fair to say though, I didn’t have any dry hits but did have to keep an eye on the e-liquid level as it was decreasing at an alarming rate.

My normal style of vaping is a long slow draw, so I decreased the power level down to 32W. This I found was my ideal setting with a nice balance between flavor and vapor.

Tweaking the airflow gave nice results and I found I preferred the airflow half open (or should that be half closed…?).

While using the supplied 0.2 ohm coil, I had no leaks or dry hits and have been using the coil for a week now with no loss of flavor. I was impressed with the flavor and vapor produced from this coil, definitely a thumbs up from me.

Temperature Control

As the supplied coils were Kanthal A1, I used another tank with SS coils to see how the TC performed on the Aegis X. I will be honest and say I don’t normally vape with TC but did find that everything seemed to work as I expected.

Geek Vape Aegis X 200W | Battery Performance


The Aegis X 200W mod is powered by dual 18650 batteries. Always ensure you only use ‘matched pairs’. Further understanding on married/matched batteries can be found in our Pairing Your Vape Batteries guide.

Battery performance is always subjective and depends on the type of batteries you use, the power you vape at and your vaping style. Because I usually vape at low(ish) watts, I opted to use my Sony VTC5A batteries, having a CDR value of 25A with a 2500mAh capacity.

I was achieving a full days vaping from a fully charged set of batteries. Using my Samsung 30Q batteries (20A/3000mAh), I was getting well over a days worth of vaping before I needed to re-charge.

How Do I Fill the Cerberus Sub Ohm Tank?


Filling the Cerberus Tank

The Cerberus sub ohm tank is a quarter turn top opening filling mechanism. It’s very easy to fill. Simply grasp the glass tank and turn the top knurled metal section anti-clockwise by a quarter turn until it stops turning.

This releases the top section from the main body, allowing you to simply lift the top section of the tank away. There are two pretty decent sized e-juice openings, choose either one to fill with your favorite e-liquid.

Once filled, line up the two notches on the underside of the top cap with the two flat indents on the top of the tank body. The top cap will slot into the tank body, then turn the top cap clockwise by a quarter turn till you feel resistance.

Quite a simple, ingenious locking system but one that is very effective.

How Do I Change The Coil In The Cerberus Sub Ohm Tank?


Unscrew the Cerberus tank from the mod. Ensure your tank is empty of e-liquid before you try to disassemble the tank, otherwise you’ll have e-liquid spilling out.

Grasp the main body of the tank and turn the airflow ring to the off position. Continue turning anti-clockwise until the bottom section of the tank unscrews and comes away from the glass and top section.

Depending on which undoes first, the coil will either be screwed into the base of the tank, or it will be screwed into the top section of the tank.

Either way, unscrew the coil from whatever part it’s still connected to. Re-fit a new coil into the bottom base of the tank ensuring the O-ring is intact on the coil as you screw it in. Don’t over-tighten but ensure it’s firmly in place.

Re-connect the top section, including the glass into the base of the tank. Carefully screw the two sections together, again not over tightening but making a firm seal. Do ensure that your new coil is primed and when filled, left to stand for 15 minutes so the e-liquid can fully saturate the wick. See our guide on Prolonging the Life of your Coil.

How Do I Charge The Aegis X 200W Mod?


As with most external battery mods, there are 2 ways in which you can charge the battery(s). Either in the mod itself or using an external charger (recommended).

Because the Aegis X 200W mod uses dual 18650 batteries, I really would only ever charge my batteries using an external charger. If you do wish to charge your batteries in the mod, at least Geekvape have included two-cell battery active balanced charging as a feature.

The Aegis X 200W has a top located micro USB port which is recessed behind a rubber plug thereby maintaining the IP67 rating. A micro USB charging cable comes supplied with the kit. Simply connect the cable into the USB port on the top of the Aegis X 200W mod and the other end into a suitable USB power source. The specified charging circuit of the Aegis X is 5V/2A.

Aegis X Battery Charging

When the Aegis X 200W mod is charging, it shows the dual batteries icon with a cycling scale, indicating the status of the batteries.

After approximately 3 minutes, the screen goes blank. Not something I expected to happen. At this point I wasn’t sure if the batteries were fully charged or not. Pressing any button brings up the screen again showing the batteries are still charging.

A pass-through function is included allowing you to charge and vape at the same time.

Charging The Aegis X Mod

Charging time from full discharge to fully charged will take approximately 4 hours when using a 5V/2A source. Obviously this does depend on the capacity of the batteries you’re using.

As with any vape device, NEVER leave your mod unattended while charging. If you prefer to charge your batteries externally and I really would recommend doing this, please see our guide on the Best 18650 Battery Chargers.

Geekvape Aegis X 200W Kit | Price


Expect to pay around £70-£80 for the Aegis X kit but at the time of writing, Newvaping have it on offer for £62.99. At this price I’d really recommend the Aegis X kit for beginner and veteran vapers alike.

Considering the fantastic performance and the sheer amount of settings and options available, £62.99 is an absolute steal!

Geekvape Aegis X Kit Review Verdict

Summary

The Aegis X mod really is a cracking piece of kit. Once you’ve worked your way around the menus, it’s a pleasure to use and own. The functionality is very impressive, having everything you’re ever likely to need in terms of vaping options. Being IP67 rated, it will also take a lot of punishment.

The 2.4 inch screen really is something else, incredibly clear and VERY big! The Aegis is big but for the size, it’s not too heavy and it really does look and feel like a high quality mod.

Aegis X Kit in Hand

As for the Cerberus sub ohm tank, even though it’s been around for a while now, it’s still a really good sub ohm tank. I liked the top fill mechanism, very easy and straight forward to fill. Coil performance was impressive and I will be trying the other coil options. The only downside was the 2ml capacity (damn TPD). Using this on a daily basis will require getting a bigger glass to increase its capacity.

Would I buy another one……….DEFINITELY!

  1. The geekvape aegis x is the single most disappointing box mod I’ve ever owned.

    After only a few months I got the dreaded “battery too low” error when nothing had happened to the mod at all.

    This thing, despite looking great, is a real piece of crap. Would not recommend.

    1. Hi Ed,
      Sorry to hear you’ve had problems with the Aegis X. Sadly some people have been having similar experiences with this mod. Have you tried contacting the seller to see if you can get a replacement?

      While this may of put you off the Aegis X, I have to say I’ve been using this mod daily for over 9 months now with no problems at all. It really does take a lot of punishment and does keep going.

      I would try cleaning the battery contacts in the mod and on the battery door to see if this makes any difference, worth a try.

      Hope you manage to get it working Ed.

    1. Hi Afshin,
      We are currently writing up a review on the Obelisk 120 kit which includes the 0.2 ohm and 0.4 ohm mesh coils. Should only be a couple more days and it will be on the site so take a look and let us know what you think.

      We’ve also reviewed the Geekvape L200 mod kit with the Z (Zeus) sub ohm tank that you might want to take a look at.
