Product intro and specs

The Geekvape E100i (or Aegis Eteno I) is the latest pod mod by Geekvape, a company that has been making excellent products for many years. As is the case with many of those products, this one is inspired by the original Aegis and its rugged design.


The E100i is an AIO in a medium-sized package. It comes with a fully featured chipset that offers a variety of modes and functions, and it is paired with a pod tank that boasts a generous 4.5 mL capacity and takes uses the P series of coils. The device is powered by an internal battery rated at 3000 mAh, and fires up to 100 watts.


The E100i is part of the Aegis line, so it has a lot of similarities to a few other Geekvape devices, like the Aegis Boost 2 which I reviewed in June. It has a tactical look, it’s IP68 rated, and comes in a similar shape. It is released alongside the E100 (called “Aegis Eteno”), which takes an 18650. So, it’s likely that the “I” in the name is for “internal”.

Build quality and design

Vaping360 placeholder image

The Geekvape E100i is a medium-sized AIO/pod that's about the size of a single-18650 mod and tank. Not the smallest or most portable AIO, but small enough to be carried around—and smaller than a multiple battery setup. It is IP68 rated, and like all their rugged mods, it won’t be the most compact because it takes a little extra space to have it be durable and water-resistant.

As with the rest of the Aegis and Aegis-inspired products, it’s a great-looking device that has a tactical look to it, and it feels great in the hand. It’s definitely a device you can take everywhere and can take a beating. I can’t say for sure what all the colors offered are since it’s not listed on their site yet, but I have found it listed as out of stock around the internet and have seen the offerings of six different colors.

There are three colored areas on the device: there is the coating which takes up most of the mod, the leather backing, and the frame that surrounds the leather. From the pictures, most of them are a full solid color (black, blue, red, and volcanic gray), while the rainbow is just all black with a rainbow frame around the leather. The beige stands out to me, though, because of the rose gold frame.

In the past, many of these Aegis devices were mostly the same color, with the differences being the frame and leather. On these ones (at least from what I can see), the entire device seems colored, making the options stand out more. However, the pod tank is only available in black, silver, and blue, so blue and black are the only two device options that completely match with their tanks.

There are three buttons on the device: a fire button on the top front above the screen and the up and down buttons below the screen. There is also a slider on the left side that locks the device, which I love. The bottom is soft and grippy, so it won’t scratch surfaces it’s put on and won’t tip over easily. The front features a 1.08-inch rectangular color screen that's bright and easy to see and features a battery meter, a puff counter, settings, etc. Same layout as most of the recent Aegis mods I’ve tried.

Getting started

Vaping360 placeholder image

The E100i is an AIO that functions like a box mod, so it’s more geared towards intermediate to advanced vapers than pure beginners. It’s also made for DL vaping, whereas most people looking to start and quit smoking will go for MTL kits, so I don’t consider it a beginner device. It’s best for people with some experience vaping and using devices, who like DL vaping and want something rugged to carry around.

To use the device, five clicks of the fire button will turn it on and off. To cycle modes, click fire three times and then use up and down to cycle through them and click fire to accept. One of the best features I love on the E100i though is the additional lock bar on the side. Sliding it down locks the device so you can pocket it without worrying about accidentally firing it.

As far as other features go, it’s heavy on modes—and to be honest, I wish some were cut out. I get that it uses the same chip as non-AIO devices they offer, and it’s a great chip as far as performance goes, but many features just aren’t applicable to this device. They should really disable them in the firmware, in my opinion.

For example, it offers full temp control, but it’s an AIO and doesn't offer an RBA deck or TC-compatible coils, so TC is not usable in this device. It also has Boost mode, which offers max power, which isn’t a mode that makes sense as you can just use regular power mode. I guess the design is for high watts consistently even when the battery is drained, but power mode should just do that, and you're still limited by the battery charge and boost circuit.

There is also a Smart mode which is just a power mode that limits the wattage range so you don’t underpower or overpower the coil. For example, with the 0.2-ohm coil, it lets you set between 60-70 watts only. I get how it’s helpful for a beginner, but the wattage range is printed on the coil, and it’s not really a beginner device to begin with. It seems companies add too many things where in most cases, simpler is better. It does have Watt curve mode (VPC), which is great, but that and power are all that is really needed. A firmware update to disable the rest would make it an easier-to-use device.

The tank itself offers adjustable air via an air slider on the top. Since the tank is held in by magnets, you’ll want to hold the glass in place while adjusting the air or the whole tank moves. Filling the tank is easy. Just hold the glass part in place and grip the top cap. Then give it a half turn to move the top cap to the side, exposing the two large fill holes.

The tank itself is fully exposed and clear, so it's really easy to see the juice level. That's something a lot of companies don’t do on these AIOs, as tanks are often recessed and tinted.  The dip tip is large and removable, and it’s a standard 810 Delrin tip, so you can use any 810 tip on it if you please.

Replacing coils is easy; just remove the tank and pull the coil out of the bottom. The coils stick out enough that you can grab them relatively easily without the use of any tools. They do also offer a 510 adapter to make the tank usable on any mod, but it’s not included.

Overall, I'm pretty happy with the usage outside of it being a bit too complex and offering some modes that I don’t find useful on a device like this.

The device is made for DL vaping and offers from a solid DL to a restricted DL vape depending on how open the air is set. It has top airflow to reduce leaking and routes the air under the coil to boost flavor.

Geekvape has been doing well with coils as of late, and this uses the P series of coils which we’ve seen in devices like the Boost Pro and B100. Due to that, the coils should be easy to find.

There are three coil options in total:

A 0.2-ohm coil rated for 60-70 watts.

A 0.4-ohm coil rated for 50-60 watts.

A 0.5-ohm coil rated for 40-50 watts.

The first two coils are included in the kit, while the third one is available as a separate purchase.

I started with the 0.2-ohm coil, and I found it best around 65-70 watts. The flavor was solid for a top-airflow device, but devices like this aren't made for flavor chasing, so it’s understandable that flavor isn’t great. You buy top airflow devices for leak resistance, not for top-notch flavor. Then I tested the 0.4-ohm coil, and found it best around 55-60 watts. The flavor was just ok—a little less pronounced than on the 0.2-ohm coil, but not a major difference. Both had above-average coil life (around 70-80 mL), so nothing wrong there. Overall, as far as top airflow atomizers go, it’s a solid vape.

Battery life and charging

Vaping360 placeholder image

The E100i comes with an internal battery listed at 3000 mAh, but I couldn’t find a charge rate in the manual, and it’s not listed on their site yet. The port is Type-C, and it’s located at the bottom of the front of the device.

In my test for the charge rate, I got a max of 1.66A, so it should be rated at 1.8A and is right up there with the faster-charging devices. Testing battery capacity, I got a little over 2300 mAh, so I consider it a bit overrated. However, to be fair across the board, most devices are overrated by about 20%. This one is not far from it, so while overrated by my standards, it falls in line with most devices like this.

Finally, I timed a full charge at approximately 45 minutes, which is excellent considering the battery size. It does have passthrough vaping as well, so you can use it while it’s plugged in.

IP68 testing

As far as the IP68 rating goes, I did throw it around quite a bit for the fun of it, and the device holds up well. I put more abuse on it than you’d normally put on a device in everyday usage. The same goes with the water test; no issues there either, so it works as well as the rest of the Aegis line. Just note that the tank itself is not rugged, and the glass can easily break and water in it will ruin the coil. There’s no spare glass included in the package, so if you break it, the tank is not usable until you replace it.

Pros / Cons


  • Excellent build quality 
  • IP68 rated
  • Tank is held in firmly by strong magnets
  • Good size for the device type and battery life
  • Five color options that are actually very different to each other (subject to change)
  • Excellent large color screen
  • Great leather backing
  • Lock slider
  • Great tank capacity (4.5 mL)
  • Easy to fill (“switchblade” style top cap)
  • Replaceable 810 drip tip
  • Tank has optional 510 adapter for use on other mods (not included)
  • Uses established coil line (P series)
  • Solid performance from both coils (0.2 ohm is slightly batter)
  • Coils can be pulled out by hand without use of tools
  • Charges fast (1.66A / 45 minutes)
  • Supports passthrough vaping


  • Battery slightly overrated (a little over 2300 mAh usable)
  • Overcomplicated for the type of device (too many modes)
  • No spare glass (a broken class renders the AIO useless)
  • Not ideal for flavor chasers or beginners



Overall, Geekvape did a solid job with this device. It has a lot of ups and only a few downs, but you just have to be the right audience for it. It’s a great option for someone who wants something they can vape DL with and is looking for a device that can take a beating. The E100i can easily survive everyday life and even some rough usage, but is still pocketable. I wouldn’t recommend it to new vapers though, as it may get a bit too complicated.

I started doing reviews at the end of 2016 bringing a unique amount of data and fair points that has made them grow in popularity. I’m an avid temp control vaper but will vape pretty much any style of vaping. My goal is to bring as much good, fair, and unbiased information to the forefront as I can to aid vapers in making informed decisions to get the best vape for their style. I enjoy helping people really get the most out of their vape and finding their “aha” moment when it all clicks into place.
