Sunone Sub Ohm Tank Overview And Performance Insights

Vapers who value clean flavor and smooth airflow often look at sub-ohm tanks such as the Sunone. It is sold as a direct-lung tank with replaceable coil heads.

We could not find a manufacturer page or manual for the Sunone Sub Ohm Tank, so its maker, size, capacity and coil type are unverified. This guide explains how sub-ohm tanks like it work and what to check before you buy.

Key Takeaways

The Sunone Sub Ohm Tank is a direct-lung tank whose specs we could not verify
Sub-ohm tanks pair best with low-nicotine freebase e-liquid, not high-strength nicotine salts

Sunone Sub Ohm Tank: Design, Features, and Performance

The details below are what to look for in any sub-ohm tank, including this one.

Device Overview and Key Specifications

Check these specs on the packaging or product listing before you buy:

Specification	What to check
Diameter	Whether it sits flush on your mod
Capacity	Tank size in ml
Coil Type	The coil head model and its rated wattage range
Fill System	Top fill or bottom fill
Airflow	Location and adjustability
Connection	510 thread

Capacity limits vary by market. The EU Tobacco Products Directive caps e-cigarette tanks at 2 ml, so EU versions of many tanks ship smaller than U.S. versions.

Replacement coils should match the model named in the manual. A coil that fits is not always rated for the same power.

How Sub Ohm Tanks Work

Sub-ohm tanks use coil heads below 1.0 ohm. Lower resistance draws more current from the mod, heats a larger coil surface and produces more vapor.

Mesh coils spread the heat over a wider surface, which many vapers find gives even heating and good coil life. Set your mod within the wattage range printed on the coil head.

Sub-ohm tanks are not a good match for high-strength nicotine salts. The large vapor volume can deliver too much nicotine per puff, so most users pick low-nicotine freebase liquid.

Build Quality and Materials

Most sub-ohm tanks use a stainless steel body with a glass section. Check the drip tip size (510 or 810) if you want to swap tips.

O-rings keep the tank sealed. Replace any that are cracked or flattened, since worn seals cause leaks.

If the glass cracks, stop using the tank until you replace it. Keep spare glass and o-rings on hand.

Top Fill Design and Ease of Use

A top-fill design lets you refill without removing the tank from the mod. Close the airflow or follow the manual's fill steps to reduce leaks.

Prime a new coil with a few drops of e-liquid and let it soak before the first puff to avoid a dry hit.

Keep e-liquid out of reach of children and pets. The CDC reports that over 80% of e-cigarette calls to U.S. poison centers involve children under 5, according to its health effects of vaping page.
