Exvape eXpromizer V3 Fire RTA Review

Exvape eXpromizer V3 Fire RTA

Here’s a look at a really nice German designed MTL RTA called the Exvape eXpromizer V3 Fire. Now the eXpromizer series has been around for quite some time with the original launching right around the time I started vaping which was a little over four years ago now. It’s definitely matured over the years with exVape the manufacturer releasing several versions and subversions of the tank while still maintaining it’s original concept of an easy to use, easy to build and good performing mouth to lung tank. Here are my honest thoughts on the EXvape eXpromizer V3 Fire.

Packaging and Contents

The tank comes packed in a nice cardboard box with an image of the Exvape eXpromiser V3 Fire on the front doused in flames. Everything inside is safely protected by a thick sponge insert. In the kit, they include the eXpromiser V3 RTA, a manual and a spares bag. In the spares bag, you get a little blue screwdriver, a spare set of orings in black and clear and a couple of spare deck screws in case you happen to lose one. Not a whole lot in the kit but everything you should need to get started.

The Tank

The 22mm diameter tank is made of stainless steel and stands between 63 and 70mm tall depending on which version you get. It comes with either a 2ml or 4ml capacity, I got the 4ml version so it’s 70mm. They’re essentially the same but the shorter 2ml version would be for TPD regions. To some older vapers, its construction will seem really familiar and many will notice similarities to tanks like the Kayfun or Taifun.

Exvape eXpromizer V3 Fire RTAStarting at the top it’s got a squape style 510 drip tip that’s made of POM. It’s comfortable enough and matches nicely with the tank. Below that is the juice flow adjustment. You can turn it to open or close the juice flow. It’s a handy feature, especially when using thinner liquids or for working on the deck.

Just below the juice flow control is the pull to open top fill cap. It’s similar to the top fill on a tank like the OBS Engine where you slide open the cap to reveal an oval-shaped fill hole in the side of the tank. It works quite well but at times it can squeeze out a bit of juice when closing it off. Below the top fill is the tank itself. It’s got a pyrex glass tank so you shouldn’t have any issues with what liquids you use.

The Tank Continued

As mentioned above it holds 4ml of e-liquid and lasts a good while depending on your build. The tank can be unscrewed from the deck if you need to install a new coil or re-wick but you can also unscrew the lower airflow base from the deck which also acts as a sort of catch cup in case of leaking. The airflow has an adjustment ring that lets you set it exactly how you want it with a series of graduated holes. It’s got two sets of holes that you can expose with one set having an extra tiny hole for a really tight MTL draw.

You can choose to expose just that one hole or a whole range of them and you can even set it for a fairly decent direct lung hit. The AFC uses two orings to seal it so there’s no compression loss which makes for a nice truly tight MTL vape. As much as the design of the eXpromiser has matured they still cling to the original design and concept despite the fact that most companies have given up on juice flow control and I don’t remember the last time I saw a catch cup base. Still, they’re handy features if you know how to use them and I think it’s nice that they stayed true to their designs.

The Deck:

The deck is really nothing special and in fact, feels quite dated at this point. It’s a two post deck that could be considered Kayfun style with a screw on either side of a bottom airflow hole. You basically build and wick it just like a Kayfun with two little troughs on either side of the deck that is perforated with three holes each. These holes allow the juice to come up from below and feed your wicks.

Exvape eXpromizer V3 Fire RTAOn Kayfuns I usually drill these holes out to allow for a bit more juice flow but on the eXpromiser. I haven’t found it necessary as they already provide three nice graduated holes on each side for the juice to come through and so far dry hits have not been an issue for me. In fact with thinner juices that juice flow control may even be necessary considering how well this thing wicks. Sure the deck might feel a bit outdated but it’s tried and true and any old school vaper can tell you it just works. Why re-invent the wheel?!

Build, Wick and Performance

Building on this tank really couldn’t get much easier, just line your coil up with the bottom airflow hole, wrap your leads around the two opposing post screws and tighten them down. You can make sure it’s lined up and sitting just above the bottom airflow hole and that’s about it. Wicking it is equally as simple and is even easier than on an earlier Kayfun because of the provided wick channels. Just cut your wick long enough to reach the bottom of the deck and tuck them in on either side. Prime your wicks, screw the tank back on and you’re good to go!

Exvape eXpromizer V3 Fire RTAPerformance wise this thing can do both mouth to lung and a restricted direct lung but I feel it’s just slightly more geared towards mouth to the lung. I’ve been rocking it mostly closed with either one or three of the holes open and it’s been a treat. Full flavour and a nice dense vape, there really isn’t much to complain about with this one. I do feel the airflow hole under the coil is a bit wide for MTL but the AFC helps to tighten things up and overall it’s been a really great experience.

Final Thoughts 

I tend to prefer MTL and single coil atomizers. So the Exvape eXpromiser V3 Fire was a very welcome addition to the collection. The overall design feels just a tiny bit antiquated. I personally dig the looks and functionality of it. It’s very well engineered thanks to the German design team that spent countless hours perfecting it. I’d have no trouble at all recommending the eXpromiser V3 to anyone looking for a solid rebuildable MTL tank. Especially one that comes packed with all of the features it bears.
