Innokin Endura Apex Tank

The Innokin Endura Apex Tank is the standalone tank component from the Endura Apex kit system. It allows existing Innokin mod users to add the Apex tank to a battery they already own, or replace a worn Apex tank without buying a full new kit. The Apex tank uses the T20S coil platform — mesh coils that sit inside a 2ml glass tank with a side-airflow design suited to mouth-to-lung vaping.

T20S Coil Performance

The T20S mesh coil is Innokin's current-generation coil for the Endura platform. The mesh design gives a warmer, more saturated flavour compared to older round-wire coils and handles a wide range of e-liquids consistently. The 0.9ohm coil is the most popular choice for beginners — it runs at 14.5 to 18W and gives a tight, cigarette-like MTL draw. The 0.8ohm coil is slightly airier and runs a touch warmer.

Compatibility with Innokin Devices

The Apex tank uses an ego-thread base, making it compatible with the Innokin Endura range of batteries and most Innokin pen-style mods. It is also 510-compatible, so it can be used with any box mod or battery that accepts 510-thread tanks, though it is designed and optimised for MTL wattage ranges rather than high-power sub-ohm use.

What E-Liquids Work Best

The Apex tank is designed for mouth-to-lung vaping with nic salts or freebase at 6mg to 20mg. A 50/50 VG/PG ratio runs cleanly through the T20S coil and avoids the wicking issues that sometimes affect high-VG liquids in MTL tanks. Browse the 10ml Nic Salts range for compatible options.

Frequently Asked Questions

Can I use the Apex Tank with my existing Innokin mod? Yes, if your mod has an ego or 510 thread and outputs in the 14.5W to 18W range, the Apex tank will work with it.

Does it come with coils? Yes, one 0.8ohm and one 0.9ohm T20S coil are included.

How often do I need to change the coil? Typically every 1 to 2 weeks, depending on how often you vape and the sweetness of the e-liquid. A burnt or muted taste on the draw is the sign it needs replacing.
