It’s official: almost all top-rated sub-ohm tanks are now top fill devices. There are still a few bottom fill items, many being phased out, and the occasional fancy side fill choice, but vapers are sure to find a top fill tank to meet their needs. Here are the best:


This is the tank you are looking for, especially if you enjoy big, thick clouds of vapor.

It is a pretty big tank, and also needs a powerful device to run it, as it is rated to up to around 200 watts. It also has a few different coil options also to fine tune the perfect vape. We recommend starting with the V8-Q4, which has a wise range of wattage, and lasts quite a while. Around 80-90 watts seems to be a sweet spot with this one, and it can handle a lot more!

It produces the best, tastiest vapor of all the tanks listed here, and massive amounts of vapor, so if that is what you’re looking for in a sub-ohm tank, you will likely love this tank!

Joyetech CUBIS

Joyetech CUBIS Tanks

The CUBIS was designed to function with the CUBOID mod and is refilled easily and quickly. Stainless steel coil heads are available for TC vaping. Take the whole thing apart to clean and replace or swap parts as you desire such as the insulated tip and SS316 heads, the glass tube if you break it, and O-rings.

A new cup design in the base prevents leakage on this reinforced tank sold in 5 colors with matching drip tips to coordinate with your choice of mod color. Hardware partially covers the tank, enhancing its potentially vibrant looks; if you select a red one, that is.

Kanger TOPTANK Mini

Toptank Mini

The 4-ml TOPTANK Mini, an upgrade of the Subtank Mini, provides the option to fill through the top cap. That is a much quicker way to carry on without dripping e juice and convenient when you are operating at high temperatures which vaporize e liquid rapidly.

Select a pre-built coil sold with the unit (0.15-ohm Ni200 pre-installed) or the RBA deck for DIY rebuilds. The TOPTANK, featured in several Kanger sub ohm kits, is also available in a number of lovely shades including blue and purple, and there is a smaller version; the Nano.

Horizon Arctic V8

Horizon Arctic V8s

The Horizon Arctic was popular but this upgrade is sure to please vapers even more with its many types of pre-built coils. Select everything from single to octuplet replacement coils, several materials, and TC-suitable builds for use with box mods like the Sigelei 90W or SMOK XCube 80W.

The 4-ml Arctic V8 allows you to adjust airflow (of course) and is made with an innovative guard against splashing through the vent. Like the tanks above, this measures 22 mm in diameter and construction is stainless steel plus glass for optimum durability and e-juice neutrality. The drip tip is insulated and coils are made with pure Japanese organic cotton.

Innokin iSub-S


Innokin iSub S

And finally we have Innokin’s newest, best tank: the iSub-S. Innokin struggled for a while but they finally managed to produce something worthy of the top mods with their 4.5-ml glass RTA. The kit contains a 0.5-ohm iSub coil and a 0.5-ohm Clapton BVC coil replacement for fitting inside the stainless steel bottom cap.

Innokin devised a simple “Open & Point” valve for airflow and a completely rebuildable product for easy cleaning. The drip tip is insulated with Delrin and can be removed.

 Aspire Triton 2

Triton 2

Aspire’s Triton sub-ohm tank is what you would expect from the people who brought you the Nautilus and Atlantis: a classy and user-friendly device for experienced vapers. Adjust airflow accurately in two places: the bottom and top caps.

You know what the bottom one is for but the top-cap valve is only starting to become familiar among vapers. This is used to change vapor temperature. Besides the top-cap valve feature, there is also 510 threading built into the top so you can replace the drip tip should you prefer an alternative material.

Of course, Aspire’s 3.5-ml tube is made from glass: Aspire didn’t have to make it very large because you can refill any time without hassle. Stainless steel hardware is durable under the stress of continuous usage. Pair the Triton with any 22-mm tube mod or a high-watt box although Aspire had their Pegasus in mind.

One 0.4-ohm coil and a low-resistance coil made with Japanese organic cotton are included. Customers can purchase an RTA kit if they like to build their own coils.
