Build quality and design

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

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.
