TFV8 Vs TFV4 from Smok
If you’re into sub-ohm vaping, then chances are that you spend more than your fair share of time in search of the perfect tools to get those huge clouds you’re looking for. It’s only natural to want the ideal rig to get the job done, right? Well, Smok is a name that most of us know all too well, and they’ve recently released a new sub-ohm tank: the Smok TFV8. It’s the latest in their series of sub-ohm monster tanks, and some are calling it the natural heir to the powerful TFV4 Tank. In this Smok TFV8 Vs TFV4 review, we’ll consider that claim and let you know what we think.


The TFV4 Tank

The TFV4 from SmokFirst, let’s be clear: this thing is a beast. It ships with a triple coil and a quad and has received a ton of praise for its RBA. Like any great sub-ohm tank, it focuses like a laser on that all-important juice capacity, clocking in at a nice-sized 5 ML capacity – so that refills can be kept to a minimum during any heavy vaping sessions. It already offers a nice selection of coil options, so you’re sure to find something that works for your customization needs.

Now, here’s the thing. There are some fantastic temperature-sensing coils, relying on either Titanium wire or Nickel 200 to sense temperature and adjust accordingly. The best part is that the coils are set up to be compatible with other technologies like the Cube II mod. That’s important, especially for those who already have a nice collection of Smok devices and want that compatibility. We tested ours using the Smok X Cube II since we had been told about that great compatibility and wanted to maximize the experience. You can check out this and some of the best box mods here. Alternatively, if you’re after a simpler vape device, then check out our list of the best vape brands money can buy!

So, what did we find out? Well, we tested at a variety of different wattage’s and started to really see vapor production at 70 Watts. As we went up in wattage, we found that the vapor production increased accordingly – with ridiculous clouds by the time we got to 140 watts. We tested it at higher settings as well but must say that 120-140 is about the max for us. At anything above 140, there’s so much vapor that we couldn’t really inhale for more than a few quickdraws. As I said, this thing is a beast!

It is important to note that you do need to get into that 120-130 range to really get the most out of your flavor. The heat is really noticeable at those wattage levels, but the vapor and flavor are just fantastic – and there were never any burnt hits.

Look, I loved the design, and have to say that this is a way better level of quality than I’ve seen with Smok’s sub-ohm tanks in the past. The coils are just outstanding, and there’s no shortage of options from which to choose. All in all, it’s good enough that it surprised me to see that they made something even more powerful.

Now for those who like building their own coils or using pre-wound coils in an RDTA setup they have just released the SMOK Skyhook RDTA Tank which promises to put a smile on your face!


The TFV 8 Tank

The TFV8 Tank from SmokThat something is the TFV78 sub-ohm tank – reputed to be the kingpin of the Smok line of sub-ohms. And why not? This Godzilla of tanks comes with an octuple coil head. That’s eight, for those of us who struggle to keep track of those things! Wattage range is rated at a wide 50 to 260 watts, and the tank offers a gorgeously reliable swivel top fill cap.

Let’s get something out of the way before we go any further. The TFV4 went through a lot of liquid – even with a 5ML tank. This thing has the same size tank but is firing with eight coil heads. If you do the math, then it will come as no surprise to learn that this device is like a dog that spent the last eight hours wandering in the desert, made its way home, and immediately went for its bowl. This is a thirsty tank and you will be refilling it – often.

As for performance, all that e-liquid use is for a good cause: you get all the vapor production you would expect from a tank that’s been nicknamed the Cloud Beast. More importantly, it is head over heels the best in its class at retaining flavor with those clouds. You do need to fire it up to at least 80W though. Anything less and that flavor just seems to hide within the liquid.

You also get a variety of different tanks with the TFV8, like those featured on the Smok Alien kit, the Smok Stick V8 and the new Smok GX2/4 Mod which all utilize the TFV8 tank.

Our View on the Comparison

I don’t even really want to compare these two devices, because their target markets are so different. For everyday cloud-chasing, I would recommend the TFV4. Period. But if you’re into extremes and want to fill up a room with vapor, then the TFV8 is your winner. That’s not to say that you can’t use the TFV8 for your everyday vaping – it does, after all, vape very well even at lower wattage’s; we just feel that it’s better left for those wild vaping sessions.
