MTL or Mouth-to-Lung style of vaping is making a huge comeback in 2018, due to the resurgence of new vapers and the increasing popularity of nicotine salts. While before you have to show around in the high-end segment for a decent MTL tank setup, now you can get affordable ones from China. So I’m developing this list of the best MTL tanks, partly from my own experience and partly from user-submitted reviews across many popular sites.
I’ve divided the list into MTL tanks and MTL RDAs, and included some pretty good MTL clones as well. Since most people are not going to make a strict MTL tank, I would have to say that this list will consist mostly of tnkas and RDAs that range from restricted lung to MTL.
The largest selection of bottom-feeding RDAs are the 22mm range, and I’ve listed them here so you can easily find one that fits your squonker.
Kayfun Prime – $120
The latest and greatest from Svoemesto! A follow-up after complaint about the restrictiveness of the Kayfun 5 even with the additional “MTL kit”.
Essentially, the 22mm Kayfun Prime recycles design like the juice flow control, top-fill and and AFC that you have already seem in the Kayfun 5. The main difference is the airflow holes itself – now adjustable from 1mm to 2mm in six increments.
Available as a 2ml tank with optional 4ml extension kit.
Innokin Ares MTL RTA – $28
Innokin collaborated with the most popular MTL vape reviewer, PBusardo, to bring his ideas to life. The tank uses a genesis-style wicking which allows the deck to be closer to the driptip yet allow for more juice capacity.
The Ares is a 24mm MTL RTA with a 5ml juice capacity. The build deck is straightforward, what they are calling a “drop-in” deck. While the Ares is pretty new, I’m sure it’s going to do really well.
ESG Skyline – $220
The Skyline RTA skyrockted in popularity since they introduced the Skycek and the concept of replaceable air-flow discs. With these discs you could go from a direct-lung to MTL rather easily, although the side adjustable airflow is still pretty huge.
There are over 12 different Airdisc configuations to choose from, with the smallest at 1.5mm single airhole. The most flexible but also most expensive MTL tank in this list!
22mm diameter and 4ml capacity when using the provided glass tank or 2ml when using the PC tank. With the new Skydrop kits, you can reduce the profile of the Skyline although at the expense of capacity.
Vandyvape Berserker Mini – $17
The Vandyvape Berserker breaks away from the regular line-up of RTAs from Vandyvape, into MTL territory. They seem to have done a good job with it, although personally I am not a fan of the looks.
There are five airflow holes from 0.8mm to 1.6mm on one side, allowing for a very tight draw. Comes with a PEI driptip and the build deck is easy to use.
22mm diameter and 2ml capacity, with an extension tank that can go up to 4.5ml.
Kayfun Mini V3 – $17
The Kayfun Mini V3, although more than two years old now, is still on the top of the MLT list for a lot of people. The airflow is just so smooth with 4x 2.2mm holes. However, tightning the airflow is a hassle, as you have to remove the 510 pin to do it.
Only 19mm in diameter, it does a decent 2ml juice capacity with a top-fill glass tank. I’ve always felt that the Kayfun Prime would be totally unnecessary if they made it 22mm instead.
YellowKiss Pico V2 – $155
The Pico V2 maintained the overall look of the Pico, while improving on the build deck, wicking and usability of the tank. You can now fit a 3mm ID coil, and remove your build without draining the tank.
However, building on the Pico V2 is only slightly easier than the V1, and you’ll find some connectivity issues when the tank/deck parts are not tightened properly.
22mm in diameter with a 2ml PMMA tank, this will look good on a lot of mods esecially with the cear / ultem parts.
Digiflavor Siren 2 – $39
Oumier has hit a home run with the Wasp Nano. Its a tiny 22mm single-coil RDA that reminds me of the Hadaly, although it’s much cheaper.
Its’ pretty low profile too, and is easy to build on. The massive posts reduce the build deck, and the side airflows are compareable to the Hadaly.
You can now get the Wasp Nano in clear or all-black as well. I have to say the black version looks fantastic. This is the best authentic squonk RDA under $20, hands down.
Augvape Merlin MTL – $19
The Augvape Merlin Mini can be mistaken for anything other than a MTL tank. It looks too aggressive, and that wide bore driptip is misleading. The central air resistors are replaceable (1.2mm, 1.6mm, 2mm, 2.5mm, 3.5mm) and it uses bottom adjustable airflow.
It’s a 22mm tank with 3ml juice capacity and top-fill design. It comes with a MTL driptip as well.
Cthulhu Hastur MTL – $27
The Cthulhu Hastur has both side-adjustable airflow holes (1.2mm, 1.4mm, 1mm*2, 0.8mm*3) and replaceable central airflow resistors (1.0mm, 1.6mm, 2.0mm, 2.5mm, 3.5mm). With these you can adjust to the exact tightness you want.
24mm diameter and 3.5ml juice capacity. They do not seem to have a TPD version for this although I could be wrong. One con of the Hastur MTL is that the build deck is not removeable unless you drain out all the liquid.
The 24mm squonk category is growing, and I’ve listed them here so you can maximize your squonk mods that support larger atomizers.
Vaponaute Le Concorde RDA – $140
The Vaponaute Le Concorde was a limited-run 22mm squonk-ready RDA with a MTL draw. There are three 1.8mm holes on one side. The topcap also has a single 1.8m airhole as an option.
Initially many people dismissed it, then it became so popular that people were willing to pay 5x the retail price for it.
The authentic is ony available from the secondary market now. However, you can get great clones of the Vaponaute Le Concorde and get that amazing smooth airflow.
