SMOK TFV8 BIG Baby Beast Tank


Product Description

The middle child of the TFV8 tank series, the Big Baby Beast Tank has a larger 5ml tank capacity and is 24.5mm in diameter, it’s just right -like Goldilocks! Coming in at about 3mm taller than its namesake, the Baby Beast, it uses the same coils as the smaller TFV8 Baby Beast and is perfect for someone who wants the larger juice capacity and wider diameter of the TFV8 Cloud Beast but in a more compact package. The Big Baby Beast also retains the wide bore delrin drip tip, and includes an adapter for use with standard 510 drip tips. Like the rest of this series of tanks, this tank features its signature hinged, sliding top fill mechanism for easily topping off the juice reservoir. The dual airflow slots are 2mm wider than the baby tank, increasing the total airflow when wide open. The trio of coil heads that it comes with diversifies your vape experience with each change.  Making it interchangeable in functionality with variable wattage or temp control mods.  Included is a rebuildable deck that really makes this tank shine in its capabilities and increase your functions and choices.  The extended replacement glass that needs to be installed for use with the taller rebuildable deck (the deck cannot be used on the Baby Beast due to the taller coil) is just another added bonus to this small wonder.  This tank easily stands heads and shoulders above its counterparts, aptly earning its name.

Note: TFV8 Cloud Beast coils are not compatible with the TFV8 Big Baby Beast, The Smok TFV8 Big Baby Beast uses Baby Beast coils and is designed for use with thicker Max VG juices and will likely leak with thinner, higher PG juices.

VapeWild’s Thoughts and Reviews:

The RBA deck that comes with this tank is a much-appreciated addition to this lineup because it gives beginners the opportunity to try their hand at building.  It comes loaded with dual spaced claptons, an uncommonly used coil type that provides so much flavor it’ll make your head spin.  This tank comes with a couple of coil options that give you a wider kind of vape experience, whether you like a “hot” vape at higher wattages, or low wattage vape.  With the drip tip being wide bore, you get a mouth full of vapor to release into the atmosphere that will make any vaper green with envy.  The longer tank glass for the RBA is another bonus item that’s great for the builder in you.  So if you can’t really get a full week’s vape out of the pre-built coils, then the RBA is going to be your very best friend.  We highly recommend studying up on building and learning Ohm’s law before beginning to build, if for no other reason than safety.  Building, while easy, can yield some dangerous results if you don’t know what you’re doing.  Watch a few videos to get the feel of how it’s done first before you start.  It will save you loads of time and money in the end.

  1. Great tank

    Posted by Brandon on May 24th 2017

    Haven't had a problem with it, no leaks, makes nice clouds, love it

  2. I love this tank

    Posted by Reanne Lenox on May 24th 2017

    I love the back up parts. The flavor is amazing. Top fill is nice. Love the price on vapewild. Give you options on your coil. This tank does more than any other tank I have owned.

  3. Awesome tank!

    Posted by Chris Carey on May 19th 2017

    First time having a Smok tank...after switching between a few over the past year this is the tank for me! The dual coil it comes with are the coils I use. I vape around 55 watts and the flavor and the clouds are both equally as good! Highly recommend the big baby beast!

  4. Love this Tank

    Posted by Jennifer Moehle on May 13th 2017

    Best Tank Ever and works like a charm... Pretty Too

  5. Great Rebuildable

    Posted by Unknown on May 11th 2017

    I got this for the rebuildable deck in it for the most part.

    The stock coils are great too, but the rebuild is where this thing shines. I love the great flavor and the easy to refill top.

  6. Amazing

    Posted by Unknown on May 11th 2017

    This tank is amazing! The flavor is so strong and the clouds are beast!

  7. Started out great.

    Posted by MeatShield on May 9th 2017

    My bro got me one of these for my birthday, at first it was great and quite a nice upgrade from my old melo 2 tank. As long as I use the prebuilt coil heads it is fine, but last night trying to use the RBA I had problems with leaking... so I took it apart and checked the cotton and made sure it was all screwed together tight. After I reassembled it the leaking was sorted but there was now a short. Again I took it apart, checked for anything that might cause a short and couldn't find anything but I bent the coils further up, just to be safe. While putting it back together the tube splintered and shot glass into my hand, though... so that's special.

    In short, if you are just going to get it and use it for prebuilt heads, all good... Great tank. Otherwise just get an RTA.

  8. Great Mod but been vapor locking

    Posted by Darrin Hommel on May 8th 2017

    I just got the rainbow model BBB... It a great mod with really nice flavor but the atomizers has not lasted much more than 3 days... The tank seems to Vapor Lock as well... I at times have to take dry hits so the juice wicks the cotton....

  9. Best Tank Ever!

    Posted by Troy on Apr 13th 2017

    I love this tank. Great selection of coils at a great price.

  10. Love it

    Posted by Ricky on Apr 12th 2017

    Love it. Fits my Alien 220w Mod perfectly with virtually no overhang. The color is great, the airflow is such a step up from the Baby Beast I was using on my AL85 before.

  11. Terrible tank!

    Posted by Jhad on Apr 6th 2017

    The only real pro to this tank is the color, its a great neon color for the rainbow option. Other than that it is the worst tank i have ever purchased. Day one it leaks all of the juice through the airholes, all over my mod. I replace and of the O rings and seals on it. Day two it does the exact same thing. I cannot get it to stop leaking. Today, day 3 while sitting next to me on my desk the glass portion of the tank just breaks. With out being touched or knocked over putting glass all over the desk and floor. A very pretty tank with great reviews all around, but overall it was a horrible performance of the tank.

  12. Best Tank So Far

    Posted by Steve on Mar 8th 2017

    Paired this with my Alien 220W mod, and I could not be more satisfied. So far, I have tried the Q2, X4 and T6. I did not have a good experience with the Q2(purchased outside). Coil was faulty. Coil wire was sticking out the rubber gasket and prevented a good connection and major leakage, so I will not be going back to that coil. I liked the X4, which I am currently testing out. So far I can say it produces decent fog and great flavor. I am partial to the T6 though. To me, it gave good flavor/hits and produced the best clouds! As always, Vape Wild killed it on shipping and price; good people.

  13. Great tank when used as a RTA

    Posted by daniel schmittling on Mar 7th 2017

    Read this full review for RTA use.Spin Wow,great flavor due to the small build deck and air holes and it is easy to build with NO leaking.Using the 28ga.triple core claptons they sell rite here.I mount the coils using the smaller screwdriver in the set and stretch them to make the inside diameter smaller to accomadate the deck and use less cotton.

  14. Cloud 9

    Posted by Brian Hoag on Mar 7th 2017

    If you have ever lived in an area that has a seasonal cold climate, you have inevitably been driving along the outskirts of a town and seen a factory of some sort spewing a GINORMOUS CLOUD into the cold night air. Any other time of the year you don't see it because it's just hot exhaust. If you want to imitate such GINORMOUS clouds, this is the tank for you. The X4 itself creates these giant voluminous clouds that you will just stand and marvel at and I haven't even gotten to the high end atomizers yet....It's ridiculous! Yes, it does drinka da juice but as a mid-level vaper I run 55W w/70P/30V or 50/50 or hell even 80/20 on an IPV 6X and the thing easily lasts all day and then some! Not a dry hit in the house. I have not even gotten to their best atomizers yet...and the flavor? Amazing. 'Nuff said.

  15. good

    Posted by Donald Lachance on Mar 6th 2017


  16. best tank

    Posted by Mel on Mar 4th 2017

    Best tanks and big baby beast tanks are all I use now. Love them. Never had a leakage problem. I use 80% vg. And I stick to the pre made x4 coils. Love them

  17. Great tank, but RBA is very flawed.

    Posted by Rob S. on Feb 23rd 2017

    This is a great tank and I enjoy it very much with the Smok coils. I enjoy the Q2 and X4 the best. T8 tends to have issues with dry hits. It's very much the big brother of the Baby Beast. The increased capacity is appreciated. I like the wide bore tip as I feel it increases flavor. The only problem comes when you deploy the included RBA. It's almost impossible to wick it correctly to keep it from leaking everywhere. Not just a little, like a huge stream of liquid will pour from the air inlet. It happens when you rotate the top closed. It creates a vacuum that pushes juice past the cotton. I think if the top seal was a bit thinner and the design of the RBA a bit better it wouldn't be an issue. If you plan on using this for the RBA, I encourage you to skip it.

  18. Awesome

    Posted by Rob on Feb 15th 2017

    I got this in replacement of my clieto tank, and for starters it hold double then the clieto, The flavor is much better and the cloud well the name says it all.

  19. The Best

    Posted by daniel schmittling on Feb 9th 2017

    Flavor and vapor are both very good and when wicked properly the RBA deck really works very well. What a great product!!!

  20. awesome tank!

    Posted by kennytoyota@live.com on Feb 7th 2017

    I've been turned off from tanks since the cleito for quite a while cause the premade coils always left something to be desired. But this tank has brought my faith in tanks back to life! Great airflow, great flavor, tons of choices for coils and they last me for quite a while.

  21. amazing!!

    Posted by Jacob Angus on Feb 6th 2017

    Great price this tank is amazing big clouds and great taste and hold a good amnt of liquid!! One of my best purchases ever!!

  22. Big Baby Beast

    Posted by Joseph Dalsasso on Feb 6th 2017

    This is my favorite tank i own. I've used all the types of coils, still cant decide which one i like best, but they all work good and provide flavor and clouds.

  23. it's amazing! !

    Posted by Jamie the enter on Feb 3rd 2017

    I absolutely love it! ! Great clouds and great flavor. Oh and the price is Greeeeaaaatttttt!!
    I highly recommend this tank!!!

  24. Flavor for days!

    Posted by Jim D. on Feb 1st 2017

    I have several different tanks and this one is by far my new favorite. To me it produces flavor and clouds nearly equal to it's big brother Cloud Beast.

    I'm running the X4 coil at 55 watts with Max VG juice.

  25. best one of the tfv8 line

    Posted by Brian harbin on Jan 31st 2017

    First off I own all 3 tfv8 this Big baby is my favorite,
    The baby tank has to little airflow,the cloud beast has to much airflow. The Big baby is just right for me.
    I run the x4 or Rba on the big baby and right around 50ish watts with great flavor and good clouds. I take normal draws or 2-3 seconds and my coils last 2 weeks plus. My last coil I was going on 4 weeks when it just started to taste off. (Not burnt)

    Of the 3 tfv8 models this one by far is the best in my opionion.

  26. (RBA only) I love it, so...

    Posted by Unknown on Jan 29th 2017

    First off, I only got this model for the RBA as I'm stubborn/cheap, don't like buying coils constantly and have 2 in the family to maintain. These tanks replaced a pair of well worn and loved subtank minis..... now getting huge, easy hits with extreme airflow from this tank, too much honestly!! The included .35 ish Clapton coils are awesome and I'm able to keep it "low" around 40w with airflow 1/3 open (despite advice everywhere to crank it to the moon) so it gives cool, huge clouds!!! Only possible downside is increased juice consumption but that's only logical with dual coils vs the single coil on my old RDA. Dual cotton wicks last all week for us vs. only 2 days in the subtank so that alone was worth it :)

    About the reported leaks: seems to help if you screw the coil tightly up into the chimney first and then into the base afterwards when rewicking.. don't over-tighten (duh)

    Zero issues with the fill lid or top gasket, feels solid and snug on both tanks.

    Other tips: Make sure you use just enough cotton as too much will gunk up more quickly and too little will allow it too leak through the bottom, finally got it perfect on my third try! Also, to make the cotton last longer I vape it down to the very bottom until I get a mostly dry hit and then refill. Easy-peasy. Been able to get 5-7 days on a rewick with 65/35 juice (American Pie)

    Also, The gunmetal color is darker than expected and the rainbow/chameleon color is lighter (but looks awesome on a green/grey wisemec 2/3)

    Vape on!

  27. not a fan if this tank at all

    Posted by pjwahliii@gmail.com on Jan 17th 2017

    This is the first smok tech tank I've tried. I was not happy with the performance at all. To open the tank is very hard and the indicator where to push it is tough to see. There is a rubber gasket under the top cap that gets nasty with juice and doesn't like to stay in the channel provided for it. I had to daily remove it clean everything and put it back in. The coils are way over rated. The coil that was rated for 90 watts I was vaping at 45. If I went higher I would get dry hits. This is not what I'm looking for in a tank. The only reason I gave it 2 stars is because even at 45 watts it chucked some clouds.

  28. Lives up to the name!

    Posted by Jon on Jan 11th 2017

    I was a little apprehensive to buy with the other review below. However, I found plenty more postive reviews. Just pulled it out of the box and it very handily lives up to its name. I am definitely glad I decided to buy, and would recommend it to anyone who is in the market for a nice tank for a decent price.
    As with the review below, my top fill slide is stiff. Thanks to that review I knew to take it easy and not put too much pressure on it. So, definitely keep that in mind while it is new.

  29. Best in Class!

    Posted by Michael Garcia on Jan 7th 2017

    It doesn't get better than this. I think previous reviewer may have overlooked the arrow on the top that advises which direction to push. I own one already and am buying a second. Look up YouTube reviews. This is the best thing out there for small prebuilt coil tanks! Solid, well machined, hits like... well... a BEAST! Highly recommend you won't be disappointed!

  30. worst tank i have seen ever

    Posted by Allen Johnson on Jan 5th 2017

    Worked fine the first day I used it. Noticed the top slide was very stiff and hard to snap in and out of place. Second day as I was trying to fill it up with juice the tank broke in half. The top slide was so stiff it pulled the coil from the center price ruining the tank. Don't think I'll be buying anything else from SMOK. Going with the free max starre pure. Btw this is the first review I have ever done just because it was that bad!!!!
