Review: TFV4 By Smok Tech

This slideshow requires JavaScript.

While making my way through as many top-fill tanks as I can, it’s hard to ignore the TFV4 from Smok Tech. With 12 different coils to choose from (including 3 RBA styles), the ability to hold a massive amount of juice, and it’s easy fill design, this tank is sure to make a lot of people happy, but it’s not all roses.

Available Coils

The amount of coils available for this tank can be a bit overwhelming to the casual vaper. 12 coils spanning a whole gamut of options. Though, because of the sheer amount of coils, it is a bit difficult to source the ones you are looking for. Some of them are easy to get, but some of the more advanced “cooler” coils are incredibly hard to find. I called 5 different local shops, and was only able to find one or two that had the most standard of the coils. None had them all, and most had none. On top of that, I had similar issues finding them available online. Most places had them listed as unavailable or sold out. Because of that, I was only able to actually test two from the Cloud Chasing Series.

Cloud Chasing Series

These would be your “standard” kanthal coils. There’s 3 options to choose from, a triple coil (.2 ohms), a quad coil (.15 ohms), and a completely crazy sextuple coil (.4 ohms). Even though these coils range from 30w all the way to 140ws, I wouldn’t recommend using these coils with anything other than a mod able to go to at least 75w.  While the triple and quad coils are rated at a minimum of 40w, my experience has shown that you probably want to stay at a minimum of about 60w-75w. That’s where these coils start showing what they can really do. You’ll get the full flavor of the juice, while still producing huge clouds.

I wasn’t able to get my hands on the sextuple coil, but I could only assume it follow the same trend. Though, since there’s 6 actual coils, you can probably get away with as low as about 50w.

Temperature Control Series

For those with a temp controlled mod, you have three options for coils. A Nickel coil (.12 ohms +/- .02 ohms), a Titanium coil (.33 ohms), and a Stainless Steel variety (.25 ohms). The nickel and titanium run within 400°F-600°F, whereas the stainless steel is about 350°F to 550°F.

Keep in mind, Stainless Steel has a much lower coefficient than Nickel or Titanium, so unless your mod specifically supports it, or allows you to manually set the coefficient, you won’t be able to use it.

Low Wattage & Clapton Series

Of all the coils, these were the ones that interested me the most, but where the hardest ones to find. The TFV4 has 3 Clapton coils available. There’s the TF-T2 and TF-T2 Air, both are 1.5 ohm Clapton coils, the only difference being the TF-T2 Air has two extra air holes bored into the coil to create a more “airy” pull. There’s also a .35 ohm coil, that allows for a lower wattage, to provide more vapor.

RBA Series

If those 9 pre-built coils aren’t enough to tide you over, the TFV2 also has 3 RBA options. A single coil deck, a dual coil deck, and a four-post single coil deck made specifically for Clapton. No matter how you like to build your coils, the TFV2 should have a deck that’s right for you. This is a really unique aspect of the tank, considering other tanks generally give you a single RBA option (if you are lucky).

Features

Besides the massive amount of coils available for this tank, it does bring to the table some other features that makes the vaping experience a pleasure.

IMG_2720-EditThe obvious one is its top-fill design. While not the first top-fill tank on the market (or even the first one we reviewed at WRV), it has one of the most convenient top-fill designs I’ve come across. When ready to fill, you simply slide open the top to reveal a pretty sizable hole for you to use to fill the tank. That hole is made from a soft plastic piece that allows you to actually stick your dropper, or bottle head directly into the hole, making sure there’s no leaking.

It’s 5ML capacity will cut down how many times you need to refill the tank, while the top and bottom airflow holes allows you to easily dial in the type of hit you want.

One of the nicest (yet simple) things about this tank is it’s ability to be taken apart and cleaned. It seems like the trend lately has been tanks that are “sealed for leakage”, but really only obstructs your view of the tank, and makes cleaning it a pain. This tank doesn’t suffer from that. It’s really easy to tell when you are running low on juice, and the whole device comes apart in pieces for cleaning.

Summary

Overall, I really like this tank. It’s massive capacity and wide array of coil choices allows you to really customize your vaping experience. I let my wife use this tank for a few days and when I even hinted at taking it back she completely veto’d the idea. As you could probably imagine, quite a few tanks have passed through my house, and I’ve never gotten a response from her like that. She loves that she only has to fill the tank once a day, and it hasn’t leaked once since we got it (I’m hesitant to say it doesn’t leak, as it does have bottom airflow holes that can definitely cause a leak, we just didn’t experience it leaking).

IMG_2725-EditThere is a single drawback that might be a deal breaker for some, or might be irrelevant to others. This tank does burn through juice fast. While the tank does hold a ton of juice, and the coils really do their job well, all that power also causes you to fly through juice.

I also noticed the tank gets a bit hotter than my other tanks. I’d chalk this up to the “weakest” coil is a triple coil, it heats up hot, and stays hot for longer.

So would I recommend this tank? If you don’t mind going through juice a little faster than you are used to, definitely! There’s not many tanks on the market that can reproduce the experience that the TFV4 can provide. From it’s huge capacity, myriad of coil options, and general quality of the tank, you won’t be disappointed.

I've always been a huge tech junky. If there's a battery and some kind of silicon, I love tinkering with it. When it comes to my vapes, I prefer the hands off approach for my every day device. A nice tank, pre-made coil, and mod with battery built in is just too convenient. One day I'll build a coil. One day.
