I know there is another thread about this tank, but I thought I'd do an actual review of this tank. Even online reviews have seemed to cover just the basics and not compare any of the different coils in the same review. So without further ado, I present my review of the SMOK TFV8. I’ve been using the TFV8 for about a week now. I had enough loyalty points built up with one of my local B&Ms that I couldn’t pass it up, so I bought a black one. After loyalty points were applied it cost me a whopping $15 after tax. For those who may have been living under a rock for the past couple of months, the TFV8 is a sub ohm tank from SMOKTech. It features a 6ml capacity, huge airflow, multiple coil options including an RBA coil head and a wide bore delrin drip tip (a delrin 510 adapter is included in the box for those who don’t like wide bore tips). Almost immediately I knew I was going to want at least one, possibly two, more of these tanks. Based on the way I vape, sub-ohm tanks are what works best for me and this tank definitely works. It produces both clouds and flavor. For me it’s a nice balance of each. I’m not looking to chuck huge clouds and I’m not looking to be overwhelmed with whatever fruit or dessert flavor I happen to be vaping at the time. So since I already knew I liked the tank and wanted at least one more, I ordered a second one. There are a few things that really set this tank apart from some of the others I own and use. The first, and probably the most prominent, is everything that’s included with this tank. Most tanks I own came with the tank and an extra coil or two and, of course, a little blue screwdriver or hex wrench. Occasionally I would find some extra O-rings or, in the case of RTA’s, some wire and some cotton, but for the most part it was just an extra coil or two. This tank includes a ton of extras. O-rings, spare Pyrex tank glass, cotton, extra coil heads, vape bands, cotton, hex wrench and a delrin 510 drip tip adapter. The first thing that actually caught my eye, though, was the size of the coil heads. Saying they are huge would be an understatement. These things are Ginormous. Seriously. They are big. They are also offered in a fairly wide variety, although all of their coil heads are of the sub-ohm variety. The coil heads included with the tank are the V8-T8 Octuple coil head (.15 ohm), the V8-Q4 Quadruple coil head (also .15 ohm) and the rebuildable base pre-installed with dual fused claptons (claimed .28 ohms). Each of the included coil heads (as well as most of their other coil head offerings) is unique. Different airflow design, different wicking slots…things that set them apart from each other and make them different experiences in spite of the same ohm rating. Of course, as I already mentioned, there’s the size. I took pics of the included coil heads and the RBA head side-by-side along with a couple of other coil heads for size comparison. The coil heads on the top from left to right are a KangerTech OCC head and an Aspire Atlantis coil head. The heads below from left to right are the V8-T8, the V8-Q4 and the RBA head. The second pic is a view of the insides of the coil heads. While I haven’t used the RBA heads from either tank yet, I did check them on my ohm meter for a couple of reasons. The first was that the claptons in the first tank looked a little sloppy to me. Almost as if someone was watching the clock before their shift ended and this was the last set they had to do before they could clock out and go home. As I suspected, it came in at .44 ohms, quite a bit higher than their claimed .28 ohms. On the other hand, the coils in the RBA from the second tank look much cleaner and they clocked in right on the money at .28 ohms. On the tank itself, the airflow is huge. It isn’t most airflow I have experienced, but it is more than adequate. Two slots on each side that can be adjusted with a sliding ring on the base. While the adjusting ring doesn’t lock into place, the friction on it is sufficient enough to keep the airflow set where you want it. I haven’t had any issues with my airflow adjusting itself, and I am frequently shoving my setup in a pocket, taking it out, repeat, throughout the day. As with the TFV4, it’s a top fill tank with a hinged top that “swings” out of the way. A convenient feature because you can literally refill while on the move without having to worry about juggling a tank top or drip tip while you fill. The fill slot is more than sufficient even for bottle drippers. That being said, don’t forget to close off your airflow if you happen to be outside on a hot day when you fill your tank. I did have one issue with leakage after a refill, but that was 100% operator error and I have had zero issues since. The vaping experience is absolutely awesome. SMOK calls it the Cloud Beast, and it is. I typically take one to two second drags and that is more than enough with this tank to fog up the inside of my car or my mancave. I have been vaping on the black tank with the V8-T8 that comes installed on the tank for a week. Again, that is a .15 ohm coil head. SMOK claims the coil is rated at 50-260 watts but recommends 120-180 watts for the best vaping experience. I have been vaping it at 120 watts. The juices I have been using have been a 30PG/70VG blend. I suspect for my personal tastes I will likely find myself going a little higher in the wattage for thicker juices and a little lower with thinner juices. I installed the .15 ohm V8-Q4 coil head on my second tank. I have been vaping it only for a few hours now, but so far my experience with it has been as enjoyable as with the V8-T8 coil head. It has been a slightly different experience, though. First, SMOK claims the V8-Q4 is rated from 50-180 watts with 90-150 watts for the best vaping experience. Next, the airflow is a slightly more restrictive than the airflow with the T8 coil head. It’s a subtle difference but it is noticeable. Finally, the particular juice I started with in this tank was also a tad thinner than the juices in my other TFV8. The juice I have been vaping with the Q4 coil is a 35PG/65VG blend. I bounced around between 80 and 105 watts with the Q4 coil head. 95 watts seems to be the optimum spot for me with the particular juice and that coil head. Now for the negatives, and they aren’t really negatives, only opinions. The first – it can get warm if you are chain vaping. The only time I really chain vape is when I’m driving. A 2+ hour commute in rush hour traffic can contribute to that. And since drinking and driving is not only stupid, but against the law, chain vaping helps me cope with the idiots on the road. The other negative is that it is only 6ml. Wait, what? ONLY 6ml? This puppy is a juice hog. I can easily go through two fills per day and be well into a third with this tank. All in all, this is an excellent tank if you like sub-ohm tanks and you are a DTL vaper like me. The airflow when using the T8 coil head and the included wide bore delrin drip tip rivals that of most RDAs I have used. There are a couple of other coil head options besides the coil heads that come with the tank, including a different RBA head, but all of the coil heads are rated at .15 or .2 ohms. The main differences between the heads are the airflow and the wicking channels. If you are a MTL vaper or you don’t like warm vapes, this tank may not be for you, although I suppose you could swap out the pre-installed claptons for you own coils and run something with a higher ohm rating. But if you don’t like warm vapes or sub ohms and you choose to buy this tank anyway, you have been warned. Last, even at MSRP, which is something like $59.99, I think this is a great tank. I didn’t pay MSRP for either tank and you don’t need to either. I have seen them online anywhere from $29 to $37. Depending on where you get it from and the cost of shipping, you may actually save money by going with one from a slightly higher priced vendor, so shop around.

Sounds like good advice Tam. Six months sounds like a good time frame. Right now there's plenty to fence with everyone's opinion and what not. I dropped alcohol 23 years ago and the process has similarities, lol. And of course, I have to try to be careful not to beat friends over the head with it as I am so glad to have found this. Don't want or become a smoke-a-nazi, lol. Sent from my iPad using The Vapor Talk mobile app

Like Rich says above a lower ohm coil will produce more heat at a set voltage than a higher ohm coil. Watts are not constant across a range of resistances as they are a product, I think, of the relationship between resistance (Ohms) and voltage. It has to do with Ohm's Law. I get the basics of, but don't understand Ohm's Law well enough to explain it. All I can recommend to get it explained is to look up Ohm's Law on the net or wait for someone here that can actually explain it. My guess as to why we set watts on our mods is that it is actually a finer adjustment than volts.

Another way to look at is a 1.5 ohm coil at 9W runs 3.7V, a .5 coil at 32W runs 4V, so a .5 coil will run 2.1V at 9W which probably isn't enough to get it hot very fast. Not much difference between 3.7V and 4V.

I've found that all factory coils for my TFV8's (I've got 2 TFV8 Big Baby Beast and 1 TFV8 Baby Beast, the smaller version) both use same coils, and on lazy days where I don't feel like rebuilding coils and installing in the RBA deck/coil I use the factory coils. Primarily the T6, X4 and the Q2 coils. All are amazing, great flavor, insane vapor production and they last a good few weeks. Check out the TFV8 BIG BABY Beast or the Baby beast (smaller version) not the regular TFV8 Cloud Beast those take different coils and aren't interchangeable. Sent from my iPhone using Tapatalk

Cutting by half is a good start when you go to sub-ohm vaping, but I've found it is more linear than that... if you want to maintain the same Nicotine "feel" as you get from the higher Ohm coil. For example... if you are using a 1.5 Ohm coil and 12mg Nicotine... and want to drop to say a 0.5 Ohm coil... you're dropping by 67% in resistance, so you should drop at least 67% in Nicotine strength too... to say 4mg (or 3mg if you are buying commercial brands that offer strengths in 3mg increments). Personally, I use 6 or 9mg at 1.2 Ohm... an when I (occasionally) use a 0.5 Ohm coil (59% reduction), I also drop my Nicotine by the same (or more) ratio... so that puts me vaping 2-4 mg strengths at 0.5 Ohms.

I don't know what kind of study you're doing, and I'm not clicking the link to find out about a few subjective or bias questions which will likely lead to zero conclusions (other than "vaping is bad", which is the go-to for the medical/dental community). As a former researcher, I can tell you the only honest study you can do, will take at least 500 test subjects and 10-20 years to conduct properly. You'll need 100 each of non-smokers/non-vapers for control group...100 each current smokers, former smokers who don't vape or use any other nicotine diversion, former smokers who vape, and non-smokers who vape. You'll have to also eliminate/mitigate environmental factors, excessive drinkers, caffeine addicts, and those who consume sugar (drinks/candy), or any other known oral-health damage causing factors. I'd wish you luck on your endeavor, but we both know you're probably not going to be investigating this thoroughly (long-term) or seriously... because next semester you'll have a new pet-project to complete for your indoctrination officials (a.k.a professors)... rather than learning real dentistry.... Sorry for the cynicism, but I've been around long enough in the medical field to know smoke-and-mirrors faux-research attempts when I see it....

Please do not spam the forum. You only need to post this once. I deleted the duplicate.

Got mine today and the vapor production is outrageous. I've vaped a lot of setups over the years, but this is light years ahead of anything I've tried before. Puts my best drippers and sub-ohm tanks to shame...x10. No problems wicking max VG juice, either.

Mine sounds it's vaping the juice sort'a like that...I had to look at the coil (tops of cotton) to see if it was burnt vaping at 125w...it wasn't.. Was told that PG will sizzle somewhat loudly at higher wattages so I switched from 75/25 to 100% VG..It quited down alot and now I can barely hear it, and get a thick, flavorful, vape...lol Sent from my XT1585 using Tapatalk

Were you ever a smoker? If so, how many packs per day, and what brand/strength? Chest pains are highly uncommon and not a side-effect of vaping, nor an indication of allergic reaction. If you were never a smoker or user of tobacco, using any e-liquid that contains nicotine is not recommended or advised. What device are you using (battery/tank) and what brand/flavor of e-liquid are you using?

It should be 304 SS, if that's the case it shouldn't be that hard, speaking as a machinist the 400 series SS can be pretty hard but 304 is fairly soft for a SS, I haven't had 304 work harden on me except when its been welded. Just to be curious what kind of racing did you do?

It is a good mod, when I got it I put 2 new LG HG2 batteries in it and haven't taken them out. I just charge the batteries in the mod, a charge lasts me 2 to 3 days. The single battery mods I have I change the batteries in them and use a separate charger to charge them. I figure the best way to keep the 2 batteries married is to just leave them in the mod. I have 3 Kanger 75w TC mods and 2 Kanger50w mods so its not a issue to wait for the 120w to charge. The NiCr mode does work for Kanthal too, after I used a Kanger Clapton coil in power mode I tried it in NiCr mode, set it at 350f when I finally ran out of juice the cotton didn't burn.

Okay, now tell me what PG/VG ratio your juices are.

Today I learned that as soon as I buy something, I will most likely immediately begin researching other cool vaping stuff. It's like a never ending cycle.
