The Beast That Is The TFV4 Smok Tank Gets A micro Makeover – Does It Work In Such A Small Package?

Smok have released a new starter kit, the Smok Micro One, comprising of the Smok TFV4 Micro tank, and the Smok R80 temperature control box mod unit.

The Micro TFV4 is the smallest version of the massively popular Smok TFV4 tank, and the Smok R80 TC, a box mod powered by an inbuilt 4000 mAh battery, 80w of power and temperature control support for Nickel, Titanium and Stainless Steel coils.SMOK TFV4 Micro Review

Out of all the current ‘all in one’ starter kits to come to market as of yet, the Smok Micro One is shaping up to be the most powerful one yet!

We are going to look at the Micro One starter kit over two reviews, as we will be looking at the TFV4 Micro Tank and Smok R80 temperature control unit separately. In today’s review let’s have a look at the TFV4 Micro tank!

Build Quality & Design

Both the TFV4 and TFV4 Mini are really solid, well built tanks and the micro version is no different.

It has the same diameter as the TFV4 Mini at 22mm, however it has the shortest height and the capacity stands at 2.5ml, unless you swap in the 3.5ml tank extension adapter. Looks wise, it’s identical to the TFV4, with the exception being the much shorter height and smaller width.SMOK TFV4 Micro Review

The same excellent features are found with the TFV4 Micro tank, so although it is smaller it hasn’t lost any of the great features found with the TFV4 and TFV4 Mini. You have a swivel top fill system, where the top cap is on a swivel hinge, so when you need to refill you simply swivel out the top cap and fill through the fill port.

The fill port however is the smallest one yet out of the TFV4 series, and you may find it a bit of a struggle to fill with a lot of bottle tops. I’d suggest investing in a needle nose bottle to fill this tank with.SMOK TFV4 Micro Review

The drip tip retains the same design found on the TFV4 Mini, whereby you have a stainless steel outer with a pyrex glass inner, and in conjunction with the drip tip airflow found at the base of the drip tip this will help to keep your vape from getting too hot.

The drip tip airflow is four adjustable cyclops airflow slots so you can finely adjust the airflow through the drip tip if need be. Airflow at the base of the tank is also made up of four adjustable airflow slots.

You can disassemble the TFV4 Micro to clean it, and you will need to unscrew the tank from the base in order to change coils, unfortunately you cannot do this with juice in the tank otherwise it will spill out.SMOK TFV4 Micro Review

The Micro sports newly designed TFV4 Micro coils that are compatible only with this tank, the existing TFV4 coils are not compatible with it and vice versa so don’t buy this if you have the original tank and want to carry on with current coils.

Good news is that much like the existing TFV4 coils, there will be a huge range of these coils available!

How Does The SMOK TFV4 Micro Perform?

Pre installed with the Smok TFV4 Micro is the Micro CLP2 fused clapton dual core, which has a resistance of 0.3ohm and is made up of a dual fused clapton coil.

Smok recommend that this coil head can be used at 30 to 60w and in combination with the reduced chamber found with the TFV4 Micro, this offers some really outstanding flavour! SMOK TFV4 Micro Review

Vapour production is excellent too, and the airflow on the TFV4 Micro offers vapor production on par with it’s bigger brothers.

The Micro STC2 stainless steel dual core is included spare in the package, and this is a dual stainless steel coil. Again Smok recommend that this be used at 30 to 60w, and this seems to offer much ‘cleaner’ flavor than the kanthal coil heads, and even better vapor production.

The added bonus with this coil is that you can use it in temperature control with the Smok R80 TC found within the Micro One kit, and take advantage of the benefits temperature coil has to offer, such as dry hit protection.

Unfortunately, as with most experiences I have had with stainless steel in temperature control, this isn’t as reliable as temperature control with Ni200 or Ti, and the odd dry hit has crept in.

If you are intending to use this as your main day to day tank, then I would highly recommend swapping the 2.5ml tank section out for the 3.5ml tank section, as this will get drained in no time at all. SMOK TFV4 Micro Review

As with the original TFV4 coils these micro coils are extremely thirsty and will get through your juice in no time at all!

Final SMOK Micro TFV4 Review Verdict

As with the TFV4 and TFV4 Mini before it, the Smok TFV4 Micro is an excellent tank that offers all round excellent cloud and flavor performance, just in a much smaller package than found with it’s predecessors.

I’d love to see a rebuild-able coil core available for this tank, much like the ones already available for the TFV4 and TFV4 Mini, however I’m sure with the wealth of coils Smok have planned for this tank I am sure one won’t be far off.

Overall the TFv4 Micro is one hell of a tank, if anyone is looking for an introduction into high power and cloud chasing, this kit will be absolutely perfect. There is all you need here to get chasing clouds with the very best of them!


  • Tiny form factor
  • Adjustable drip tip airflow
  • Massive airflow for a small tank
  • Adjustable capacity
  • Great flavor
  • Excellent cloud production
  • Swivel top cap top filling system
  • Wide range of different coils available
  • Easy to swap coils
  • Can disassemble tank for cleaning
  • Pretty much leak proof


  • 2.5ml capacity is tiny, and these coils will drink up that juice in no time at all
  • Very small fill port
  • Not compatible with existing TFV4 coils
  • Tank itself gets hot quickly when putting high wattage through it
  • Cannot change coils with juice in the tank
  • No RBA coil yet

Been vaping full time for three and a half years, started on cigalikes for a fair while then curiosity got the better of me and I moved onto an ego/ce5 set up after, a month or two later I was seeing people walking around with these interesting shiny tubes and I thought 'I gotta get one of those'. Before I knew it a trip down to my local B&M got me my first VW mod, an Innokin SVD, paired with an iClear 30, and I was hooked. Soon after that I was jumping to VW mods both box and tube shaped, before I then made the jump to rebuilding and thus sub ohming, with my first RDA and mech mod. These days I'm still preferring mechanical mods, but using VW mods with both RDA's and tanks alike whilst on the move, most importantly I am still loving vaping!


  1. To start off I have been Vaping for about a year and a half now, so I am familiar with vaping, setting up tanks, etc. . I recently bought a SMOK Micro TFV4, to use at a wedding I was going to out of town. I was looking forward to using it, but I can’t. I have had nothing but problems with this leaking, it leaks so much that I can’t even get a vape out of it. By the time I am ready to put it on the power unit, it has already leaked thru. And has dripped onto the power unit and me. I have checked and double checked the washers, the tank and everything on the unit. I have lost way to much juice over the assembly . Not to mention the clean up I have to deal with every time I fill the unit. I can’t believe how disappointed I am. There are no cracks or any marks on the washers, etc. I have checked and double checked. To make sure that I assembled it correctly.I even went onto some videos out there on instructions for assembly. I have it connected to a Sigelei – 150w temperature control unit. Thoroughly discusted with this product. I bought it Locally from The Steam Co. 547 Boston Post Rd. in Orange, Ct.
