Product intro and specs

The Geekvape Aegis M100 (or Mini 2) is the latest box mod from long-time popular manufacturer Geekvape. By now, most vapers know who they are as they’ve made some great products over the years. Too many to list, but they’re a very solid and reliable company overall, with only a few hiccups along the way.

The M100 is the latest in a long line of “Aegis” styled products. It started with the original Aegis, which was the first (or at least one of the first) IP67 water and shock-resistant mods. Since then, they have had many products in that style, and pretty much all have been good. The M100 is the sequel to the Aegis Mini and comes with an internal battery with a 2500 mAh capacity. The mod itself is rated for a 100-watt output and it comes in a kit with the Z Nano 2 sub ohm tank.

Price: $64.95 (at Direct Vapor)
Colors: Black with black leather, silver with grey leather, grey with green leather, navy blue with blue leather, and more.

First impressions

Off the bat, I’ve reviewed pretty much every mod in the Aegis line. The Aegis, Aegis X, Aegis Solo, Aegis Mini, Aegis Legend. You name it, I’ve reviewed it. They are great mods. While the M100 isn’t named “Aegis” on the box, it is listed in the Aegis section on Geekvape’s website, and it’s very similar in design to many of the mods they release. So, in short, not really a stranger to these devices.

The M100 is extremely similar to the Aegis Max with a few improvements like the screen and the USB placement.  It also has a handy lock switch on the side, which is a nice addition feature-wise. I’ve first seen them do this on the L200 I recently reviewed. Some may say it’s a bad thing to have so many similar devices, but I see it as a good thing. If it ain’t broke, don’t fix it.

Like the rest of the Aegis line, the M100 looks classy and tactical, feels great, is easy to use, and just works. I got exactly what I expected when I heard I’d be getting sent another Aegis, and it makes me happy that they didn’t try to reinvent the wheel and ruin it.

Build quality and design

Anyone who has used an Aegis should know what to expect in the design and build quality department by now. The M100 does a great job of being like its predecessors. It’s nicely built. It feels solid, not cheap or flimsy, and there’s some heft to it for sure. The fire button is rectangular but with the edges cut through on the front of the mod and slightly angled up on the bottom, same as in most of their other mods.

Below the screen, there are the up and down buttons. On the left side of the mod, there is a switch you can slide up and down which completely locks the mod—so you don’t have to turn it off to pocket it. That comes in handy for safety. The USB port is Type-C and located above the screen underneath the rubber plug. It really blends into the mod. Nobody would know there is a USB under it just by looking at it. Makes it look sleek.

It’s not a super small device, but it’s got a good size for an internal battery rugged mod. It features a large 1.08-inch color screen that’s clear, bright, and looks great. The 510 pin is great and gave me no issues with any atomizer, and the included tank fits nicely on it and looks great.

As for colors, they have six options listed above. I have the rainbow with black leather one, which is very nice looking but also very shiny and a fingerprint magnet. The entire visible body outside of the screen and leather is rainbow so it’s not a small difference between color options. The leather itself is black and looks and feels great. There is no silicon outside cover like we see on many of these mods though, but I like that as it makes the color options stand out.

Branding was kept nice and simple. The metal frame in matching color on both sides of the leather has “Geekvape” engraved into it, and there’s also a small Geekvape logo on the USB cover. Overall, it’s a great-looking and well-built mod. There is no button rattle at all either.

Features and functions

The M100 mod has all the features we’ve seen on the Aegis mods over the past years. Nothing new, but everything you will need. You have Power mode (watts), Temp control mode for Ni200, Ti, SS, and TCR, Bypass, and VPC (power curve mode). Nothing fancy or overbearing, but all the needed features we expect to have in a regulated mod are here.

Using the Geekvape M100

As far as the menu goes, It’s the same as the original. Here is a quick rundown of basic operations:

  • Five clicks of the fire button to turn on and off
  • Three clicks to enter menu mode
  • Use up and down in menu mode to cycle through modes and fire to accept
  • After selecting a mode you can use up and down to adjust within the mode and fire to accept
  • Hold fire to exit the menu
  • Fire and up or fire and down will adjust the screen brightness
  • The switch on the side locks the mod so it can’t fire or be adjusted

Overall, very simple and easy to use with a good menu. I personally love the ease of use of their menu system.

Battery and charge rate

The USB-C port is located at the front of the device underneath a plug. They list the device at 2A charging with an internal battery rated for 2500 mAh. The max charge rate I got during my testing was 1.90A, which is more than good enough to earn a 2A rating, as most will round up. It does allow for passthrough vaping as well, so you can vape while it charges.

I timed a full charge at 1 hour and 21 mins, which is good. For battery capacity, my testing equipment gave me a usable 2102 mAh. It’s not uncommon for companies to overrate battery sizes, to the point where I expect them to be overstated by 20% every time. This one is overrated by 16%. Nothing egregious, but I will ding them a little for that.

Power mode performance

Geekvape only list two max outputs; watts at 100, and volts at 8.5. I do wish amps were listed as well. During my testing the max achieved wattage was 104, so their 100-watt rating is excellent. The amp limit I got was 29 amps with a 0.1-ohm coil, which is average for internal battery mods.

The volt limit I got was 8.1+, and I say plus because I was hitting the watt limit with a 0.63-ohm coil. So, there is a boost circuit like they say. I’m sure it can hit the 8.5V listed with no problem if you use a higher ohm coil. Either way, the volt limit will never be an issue. It does tend to hit a little a low under 0.2 ohms, but 0.2 ohms or more it’s pretty accurate or a little high. Overall, really good performance like I’ve come to expect from the Aegis line of mods.

The mod adjusts in 0.5-watt increments. It scrolls fast and round-robins as well. One thing I will point out is that I don’t think mods should be pushed to 100 watts on a single cell. The included coils don’t even need over 60 watts, so they could have made this an 80-watt mod and it wouldn’t have made a difference to end users. Not a big deal, as most people won’t be pushing 100 on this device, but just something to point out to manufacturers. A good performer, as expected. You can see the full test results above.

Temperature control performance

Using SS316L Wire in SS mode (TCR for SS mode is 105) I tested four builds:

A simple round single coil
A simple round dual coil
A fancy wire single coil build
A fancy wire dual coil build

As far as performance goes, the Aegis line originally wasn’t very good at TC, but they made it work on the ones after the Legend. Then, I recall another Geekvape mod being good, but having a weird low-wattage limit. The Nova was really good for TC too. So overall, it’s been up and down for Geekvape as far as TC goes.

In this mod, the power is fully adjustable in TC mode with the full 100-watt limit. The performance I got on here is similar to the Nova and L200. It’s better in SS mode, even though technically it’s not the correct TCR for SS316. It still works great and is pretty accurate. A little on the strong side, so around 430F you’ll get a nice warm vape with plenty of room to adjust. It’s smooth and consistent and works really well. Overall, a good mod for temp control usage.

Z Nano 2 tank rundown

Ok, so let’s do a quick rundown of the tank. The tank included in the kit is the Geekvape Z Nano 2 sub ohm tank, and it uses the B coil system. It’s a pretty basic sub ohm tank top airflow to minimize the possibility of leaking, a 3.5mL capacity, and a quarter twist top cap that comes off for filling the tank. The coils are plug and play and the drip tip is a standard Delrin 510 tip.

To replace the coils, unscrew the base of the tank and then pop them out. You can’t do it with a full tank, but it can be done with about a 50% full tank, which is nice. But probably better to fill when it’s empty. However, the coil is hard to grip even though it sticks out a fair amount, so you’re best off using the included tool to pop it out, or use a flat head screwdriver or something similar. I wish it was easier to replace on the go without the need for a tool.

The quarter twist fill is excellent and my favorite filling design. They fixed the issue I had with the last Z tank I reviewed where you wind up taking the airflow control ring off along with the top cap. This one is much better to remove, so nice small improvement there. There are two large fill holes with no flappers and it’s really easy to fill.

There are five coil options in total, and it uses the same B series coils that were also used in the Z Nano as well as the Aegis Boost and a few others. They also added a 0.2-ohm option. Here’s a list of the available coils:

Geekvape B1.2 Coil
Geekvape B0.6 Coil
Geekvape B0.4 Coil
Geekvape B0.3 Coil
Geekvape B0.2 Coil

The two included in the package are the B0.2 and the B0.6. I started with the B0.2 coil which is rated 50-58 watts, and I found it best around 55 watts. The flavor was pretty average. It may just be the top airflow which is known for less flavor—that’s the sacrifice made for the better leak protection it provides—but I wasn’t blown away for sure. But clouds were solid, and it vaped nicely. Overall, a decent coil.

Then with the B0.6 rated for 15-25 watts, which I found best at around 20 watts. Flavor was really poor on this one. There’s just not much flavor coming through at all. It’s really too low of a wattage for this tank, even with the airflow mostly closed. This tank needs higher wattage coils to get any sort of flavor in my opinion.

Overall, I’d say that this tank isn’t for flavor chasers. But then again, nothing with top airflow is. It does provide good leak protection, so it’s a decent tank with the higher wattage coils. If you aren’t too worried about the best flavor it’ll get the job done, but there are better tanks on the market. Top airflow was made for leak protection, but in reality, most good bottom airflow tanks won’t leak anyway unless they sit for long periods unused.

IP68 testing

As far as being IP68, it should come as no surprise, but it passed easily as usual. No issues leaving it underwater for 30 minutes, and no issues dropping it. But like the other mods of the Aegis line, the screen itself and the buttons can be a weak point of cracking or breaking—although the mod will still be usable. I would like Geekvape to give more protection to the buttons and screen at some point in a redesign. But all in all, very happy with its durability.

Pros / Cons

  • Great build quality
  • Nice shiny finish and leather backing
  • Lock slider is a nice feature
  • Large clear and bright color screen
  • IP68 rugged and water-resistant
  • Easy to use menu
  • Accurately rated for watts and volts
  • Boost circuit
  • High amp limit
  • Good power mode performance
  • Good TC performance
  • Watt curve mode available
  • Fast charge rate (1.90A)
  • Battery rating is a little overstated (2101 mah)
  • Included tank is just “meh” overall
  • The 0.6-ohm coil is too weak for this tank
  • Replacing coils basically requires the included tool

Verdict

Same as the rest of the Aegis mods, I just can’t really find anything bad about the M100. All mods of this line are great, and if you haven’t had one before, now would be the time. The M100 isn’t anything new, but it’s still excellent and a mod anyone would be happy with. It’s a good option for beginners who want something with an internal battery that looks great, performs well, and will survive everyday drops and keep ticking.

As far as the tank goes, it’s not that great. But to be fair, most included tanks in kits really aren’t. So, like in most kits, you’d be better off just getting the mod and buying a separate tank. If you are in the market for a new mod, give this one a look for sure.

Let me know how you feel about the M100 in the comments below!

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.
