FRONT VIEW - INNOKIN MVP5 AJAX 120W STARTWell, hot damn, Innokin! We’re not even going to try and pretend that there’s much wrong with the new Innokin MVP5 Ajax kit. There isn’t. Unless you’re SO opposed to integrated battery devices that you won’t even consider firing this up, Innokin just found its way onto a ton of year-end “best of” lists. Yes, it will likely be on ours.


My very first box mod was the original MVP, so color me biased if you want. But there’s no denying just how good and powerful this 120-watt surprise really is. Let’s get to the specs.

Official Description of the MVP5 Ajax Kit:

WHITE - INNOKIN MVP5 AJAX 120W STARTPresenting the Innokin MVP5 AJAX 120W Starter Kit, an incredible vaping box mod kit, featuring a large integrated 5500mAh rechargeable battery, survival suite, and is equipped with the Innokin AJAX Sub-Ohm Tank.

5500mAh Battery!

The MVP5 Box Mod doubles as a power bank, offering 5500mAh of rechargeable battery capacity, making this vaping system to last a long time in between recharges. In addition, the MVP5 power bank provides a nifty and useful survival suite, making available a barometer, flashlight, altimeter, compass, and thermometer to help when the going gets tough.


In case of emergencies, the Innokin MVP5 is equipped with many survival features that are missing from other vape set ups. Furthermore, the AJAX Sub-Ohm Tank that is paired with the MVP5 works wonderfully, utilizing the smart wattage identification, matching the wattage output to the installed coil within the AJAX Sub-Ohm Tank.

Impressions/Aesthetics – MVP5 AJAX KIT

Right out of the gate, kudos to Innokin for not forgetting about the sub-ohm crowd. Since most of their output lately has been focused on mouth-to-lung vapers and ex-smokers, thanks to some seriously high-profile endorsements, I wasn’t sure if we were going to see a higher-wattage device from them anytime soon. But the MVP5 offers a more-than-respectable 120 watts of power, alongside external device charging, and even a strange flashlight feature that’s probably only good for absolute emergencies.


BLACK/RED TANK - INNOKIN MVP5 AJAX 120W STARTBecause it’s Innokin, the MVP5 still drips with old-school design aesthetics. Though there’s some nice textures in the zinc-alloy chassis, by and large, this is a simple, no-nonsense BOX mod. Sure, there’s a fantastic, full-color OLED display on the side to break up the “antiquated” feel, but there’s really nothing here that we didn’t see years ago, on much less-advanced devices.


That said, everything here is built well, and offers a reassuring heft in the palm. A lot of that can be attributed to the integrated 5,500mAh (!) battery, but also to solid construction, and a complete lack of anything unnecessary. Everything that’s here needs to be here, and nothing more.


One MINOR quibble comes with the 510 connection, which seemed to have a slight amount of wiggle and play when attaching larger atomizers. It never led to any connection or firing concerns, but it’s worth noting for longer-term use.

Standout Features

I wish I was writing about the included AJAX sub-ohm tank here, but truth be told, the tank — while perfectly fine and solidly performing — seems a little unnecessary. Innokin just created a standout series of PLEX sub-ohm tanks that had some strong performance marks, but it seems like they’ve taken a back seat to the new AJAX series.


PACKAGING - INNOKIN MVP5 AJAX 120W STARTWhile there’s nothing inherently wrong with the AJAX, there’s simply nothing that makes the tank feel like an improvement over the rock-solid PLEX devices. And the AJAX’s compatibility with the PLEX coils only furthers the point. In short, use the AJAX, enjoy it, but don’t expect to remember it after the experience is over.


No, in reality, the standout feature on the MVP5  is the absolutely, unequivocally awesome performance of the integrated 5,500mAh battery, which outlasted my BEST 18650 cells under chain vaping conditions, and came damn close to dethroning my best 21700s. No, it’s not marketing talk. No, it’s not hyperbole. And no, it’s not me pandering to Innokin. This internal cell puts competitors to shame, giving me nearly a full day of heavy vaping before I had to plug in. Seriously.


The onboard USB-C charging is the only hangup, with slow recharge times and inaccurate battery readings while doing so. It’s not so slow that it should affect your decision to buy the MVP5 but plan ahead before taking the mod out for the night.

Vaping the Innokin MVP5 Ajax Kit

AJAX TANK TOP - INNOKIN MVP5 AJAX 120W STARTSmoother than Alicia Keys reading nursery rhymes, the MVP5 kit defies all logic by producing near-instant firing times, and consistent wattage ramping all the way to the mod’s 120-watt limit. Two weeks into my testing, I have yet to experience any misfires, power spikes or stutters — a seriously impressive statement for an integrated battery mod.


Though I predominantly used the included Ajax tank for testing, this performance was equally good using any of the tanks, RTAs and drippers in my collection. No matter if I was MTL’ing it with some other Innokin tanks, or pushing the 120-watt limit to the edge, the MVP5 handled my atomizers with precision, correctly nailing resistance and recommended wattage every last time.

AJAX TANK PARTS - INNOKIN MVP5 AJAX 120W STARTThe TC and TCR modes all worked as advertised, but I recommend staying with wattage mode unless you’re hellbent on using the last of that titanium wire in your vape collection. Not only is it easier, but the experience is arguably more immediate and powerful when vaping this way.


Because of the weird, outdoorsy marketing schtick Innokin is using for the MVP5, I need to mention the built-in, 6-mode flashlight, altimeter, barometer, compass and temperature detection are certainly welcome additions for any fledgling outdoorsman. But if you’re an active, outdoorsy vaper, chances are you already have these items in triplicate, so we’re not going to make a huge deal about this.


If the MVP5 had solar-powered charging, we might be more excited about these “Swiss Army Mod” features, but as it stands, the MVP5 isn’t an awesome device BECAUSE of these extras. It’s awesome in spite of them.


  • Amazing integrated battery performance
  • Gorgeous OLED screen breaks up the old-school aesthetic
  • Durable and versatile


  • Survival tools extras are a little silly
  • Ajax tank isn’t as good as the PLEX
  • They didn’t send me two
