Vaporfi Volt Sub Ohm Tank Review

Vaporfi Volt Intro

In this article we review the Vaporfi Volt hybrid tank. The Vaporfi Volt is a sub ohm tank very much like the Kanger Subtank Mini, but with some small tweaks and improvements.

Vaporfi are a high end US based producer of e-cigs and vaping gear and have a fantastic offering of products and e-liquids aimed at all levels of vapers. If you haven’t already been in one of their stores, I would highly recommend doing so. Their lay outs are awesome and remind me a lot of the Apple stores!

The Vaporfi Volt is a sub ohm vaping tank/glassomizer and comes with an RBA (rebuildable atomizer) a 0.5ohm occ coil and also a 1.2ohm occ coil. The RBA and 0.5ohm coil will require a device that is capable of firing below 1ohm and down to 0.5ohm.

As the Volt is a sub ohm tank, you will need the appropriate equipment to use it with. We recommend using mini box mods like the Vaporfi Vox II or the Eleaf iStick 50W/30W. These devices have the required power and capability of sub ohming, which will be necessary when using either the RBA or 0.5ohm coil that comes with the Volt. If you are unsure if your device will work with the Volt, just drop us a comment below or message Vaporfi directly.

Notable Remarks

Differences between the Kanger Subtank Mini and the Vaporfi Volt

So as far as I know Vaporfi contracted out to Kanger to provide them with a slightly modified version and improved version of the subtank mini. There are a few nice little tweaks on the Volt that improve the original subtank mini. Vaporfi also provide a 90 warranty alongside a 30 day money back guarantee as well as a free 30ml e-liquid. The key differences I have been able to find are listed below:

  • The Vaporfi Volt comes with wider juice flow holes on the RBA
  • The Volt has different insulators made of slightly different materials to the ones on the original subtanks
  • The Volt comes with green colored o-rings that are exclusive to Vaporfi
  • The Volt comes with a 30 day money back guarantee
  • The Volt has a 90 day warranty through Vaporfi (who are based in the US)
  • The Volt comes with a free 30ml bottle of e-liquid
  • The Volt comes with a Vaporfi written user manual, which goes into great depths into using the Volt and making coils for the RBA etc. (and all in good English!)


Just like the Kanger subtank mini the Volt stands out in terms of flavor from the other sub ohm tanks. The organic cotton coils are ridiculously good and means that the flavor from the Volt is absolutely exquisite. If you haven’t tried a sub ohm tank before you will shocked at how much better the flavor is compared to old style tanks and clearomizers.

Vapor Production

The vapor production will vary depending on what type of coil you are using and what wattage you are vaping at. Generally the vapor will be greater on the 0.5ohm coil and the RBA. If you are looking for big clouds the Volt will not disappoint when compared to other sub ohm tanks. When used at higher wattages (25-30) the Volt produces a nice warm vape. If you haven’t used a sub ohm tank before then this warm vapor might take a little getting used to.

Air Flow

The air flow is the same as on the Subtank mini and gives you several different air flow settings to choose from. When lung inhaling I use the Volt on the largest air flow setting and it provides plenty of air into the coil.

Additional Accessories

The Vaporfi Volt kit comes packed with a range of accessories and different coils. Note the kit comes with a 1.2ohm coil, a 0.5 ohm coil and a RBA deck. I will explain the differences for any beginners further down the page.

The Volt kit also comes with a free bottle of 30ml e-liquid as well as a user manual written by Vaporfi themselves. The user manual goes into great depth on how to use the Volt and how to make your own coils for the RBA section. This is great for those who are using a sub ohm tank for the first time.

The Volt also comes with a screwdriver and spare screws for rebuilding the RBA as well a spare pre-made coil for the RBA.

Of course, as with all Vaporfi products, you get their 30 day money back guarantee as well as a 90 day warranty on the Volt, which you won’t get on the subtank mini. This combined with the fact that you will be dealing with a reputable US based company, add value in my opinion when purchasing a product. Particularly if you are new to the vaping and e-cigarette scene, it is nice to have this piece of mind when purchasing your vape gear. Returns and customer service is nice and easy with Vaporfi beign based in the US, so you don’t have to worry about sending your product back to China etc.

I love the green o-rings on the Volt. At first I didn’t think I would like the green color, but I now think they look absolutely stunning. No doubt the green color won’t be to everyone’s liking, but as you can see from the pictures below, it looks pretty sweet!

In my opinion the Volt sub ohm tank looks best on top of a mini box mod like the Vaporfi Vox 2.

No leaking!

Lots of people complained about the Kanger subtank mini leaking through the air-flow holes. This hasn’t happened at all with the Vaporfi Volt and we have been using it with a range of different PG/VG e-liquids over the period of 2 weeks. I noticed the Volt has a small rubber insulator where you screw in the coils and this isn’t something I have on my Kanger subtank mini. Perhaps this and the new o-rings is helping stop the leaking.

Is the Vaporfi Volt tank for me?

You need to realise that the Volt is a sub ohm clearomizer, which means it acts differently to other clearomizers you may be used to. For the 0.5ohm coils and RBA you will require a device that can fire below 1 ohm down to 0.5ohm and will power to at least 20W. If you aren’t sure about what device will work with the Volt drop us a comment below or contact Vaporfi directly. I would recommend using the Volt on the Vaporfi Vox II mini box mod.

As the Volt is a sub ohm tank, it produces a lot more vapor than other standard clearomizers. This means it uses a lot more e-juice than other clearomizers do. As you are therefore inhaling more vapor you are also inhaling more nicotine, so you will therefore need to select an e-liquid with less nicotine. My brother and I use 0.3mg of nicotine when using the Volt and other sub ohm tanks.

With its very large air flow settings the Volt isn’t great for mouth to lung inhaling, as you would be accustomed to on some smaller tanks and mini e-cigs. This means to use the Volt effectively you will need to direct lung inhale, which might take some getting used to if you haven’t done it before.

The flavor on the Vaporfi Volt surpasses any other clearomizers and really gets the best flavor out of your e-juice! If you want big clouds of vapor the Volt will also be a perfect match for you. The vapor production is very impressive!

Which coil should I use with the Vaporfi Volt?

Vaporfi Volt 1.2 Ohm OCC
Vaporfi Volt 1.2 Ohm OCC

So the Volt kit comes with three different coils: 0.5ohm coil, 1.2ohm coil and the RBA (rebuildable atomizer). The 1.2ohm coil will work on most standard type batteries like the one that comes with the Vaporfi Rebel II and the Rocket battery. The 1.2ohm coil works really well in my opinion, but isn’t as rich in flavor as the 0.5ohm coil and the RBA and also doesn’t produce quite as much vapor.

The 0.5ohm coil is a sub ohm coil and will therefore require a device that fires at 0.5ohm. Mini box mods like the Vox 50W will work well with the 0.5ohm coil. The 0.5ohm coil, will in my opinion produce better flavor than the 1.2ohm coil and also produces slightly more vapor.

Lastly the RBA comes with a pre-built 0.5ohm coil, which again means that your vaping device will need the capability of firing at that range. The RBA comes with a

pre-built coil already installed. You will then need to wick it with some of the provided cotton. There is also one spare pre-built coil that you can use.

The RBA deck gives you the ability to make your own coils and find the perfect ohmage and coil build for your vape. The RBA flavor, depending on your coil build, is in my opinion even better than the 0.5ohm occ coil, so definitely give it a go!

Tip: For us the wattage sweet spot when using the 0.5ohm coil is around 25W.


The Vaporfi Volt is an impressive sub ohm tank and we like the additional features you get with the Volt over the standard subtank mini. The larger juice flow holes on the RBA make a big difference, the new peek insulators, improve the flavor and the green o-rings look pretty sweet!

The fact that you get a free bottle of 30ml e-juice with the Volt kit, as well as a 30 day money back guarantee and 90 day warranty, means that the Volt is well worth getting if you are looking for your first sub ohm tank! It is slightly more expensive than the original subtank, but we think the modifications alongside the free e-juice and warranties make it well worth the extra few dollars.

    This tank is $60, but received a 90 on price. The Atlantis 2 is less than half the price and scored an 80. Is there something factored in that I don’t understand?

    • Thanks for pointing that out Brian, the scores are the wrong way around.

  • Scott

    I bought one of these tanks and im currently waiting on shipping it back. It leaked 30 days into using it. The free liquid is disgusting as i filled one tank and dumped it right out. The user manual says to wrap the wire 10 times around the screwdriver however if you know anything about kanthal it comes in about 20 different sizes. The customer service is clueless and overall i thought this was an overpriced poc. On the flip side the green o rings arent bad but the design is def flawed.

    • Thanks for the feedback Scott. Vaporfi have a new sub ohm tank coming out soon, so I hope it performs better. We didn’t have any issues with the leaking on ours and it never leaked unlike our Kanger Subtank. Leaking with sub ohm tanks seems to be a bit hit and miss. Hopefully you can get your money back on that one. If you have any issues let me know, and I will email my contact at Vaporfi. I will also email Vaporfi this feedback, as they do take feedback very seriously. Thanks!

  • Brandon Ewing

    Will this work with the kangertech subox mini? Ive had my subox for a week. Dropped it and cracked the tank so im now researching for a better tank. Im still new to this so I might stick to the 1.2ohm coils for now. Also, in the week ive had my subox the tank has leaked out of the air holes before being dropped yesterday. Other than the tank i love the subox. Thanks In advance!

    • Hi Brandon. This tank is a bit dated now, although very solid. They have a new one on the horizon most likely. The Apollo Phazer could be a good option and also the Atlantis 2 or Triton on the 0.5ohm coil. Check out our reviews for those!

    • Andrew M. Sheppard

      Hi Brandon – I know this comment is coming in 3 months later but check out SKU 2147802 on FastTech. “Authentic KangerTech Replacement Pyrex Glass Tank for SUBTANK Mini” @ 1.87 USD, free shipping fr China. It’s worth the ~23 day wait, IMO. I ordered two. SKU 2390700 is the “Plus” model of the RBA…. better wicking!. FWIW/IMO.

      Also, SKU 2191600 may be relevant to your interests. 1.38 USD for five pc set? Heck yeah.

  • Virgil Allred

    I have a sigelei mini 30w. Would this be a good tank, if not which one would you recommend?

    • It will work well Virgil on the Sig 30W. I have heard though that Vaporfi are bringing out a new tank, so might be worth waiting for that. Also take a look at the new Kanger subtank mini (black or white or stainless steel) as those will have the new vertical coils and are basically the same tank, priced at slightly less (albeit no money back guarantee).

  • Virgil Allred

    How well will it work for sigelei mini 30w. Or what would be better?

  • Anthony Ang

    Will it work on my hcigar vt40 mod??

  • AC130USpooky

    try 27W for the 0.5ohm atty, thats the sweet spot i found on my Kanger

  • James

    Will this work well on the istick 30watt?

  • SUdheer

    Hi, can i use this tank with my joyetech ego one mega 2900 mah battery?

  • Jennybomb

    I’m good to go if I use this with my Kangertech sub box mini right? I love the 0.5 coils. Probably won’t look the best though.
