Z Nano 3 Tank Highlights
Push to Fill
Press the top cap to open the fill port. Geekvape says the cap stays attached, so it can’t get lost.
Adjustable Top Airflow
The airflow sits at the top, which Geekvape designed to resist leaks, and you can adjust it.
B Coils
The B0.2Ω Boost Version coil comes installed, rated 50W to 58W for DTL. A B0.4Ω Boost Version coil, rated 25W to 35W for RDL, is in the box.
5ml and a 510 Drip Tip
The Geekvape Z Nano 3 Tank holds 5ml. Its 510 drip tip comes off, and a wider-bore spare is in the box.

How to Set Up the Z Nano 3 Tank
- Fill it: press the top cap to open the fill port, fill the tank and close it.
- Prime it: let the coil soak for a few minutes before your first puff.
- Set the power: start at 50W for the installed B0.2Ω coil, or 25W for the B0.4Ω coil, and work up.
- Tune the airflow: adjust the top airflow for a looser or tighter draw.
Who the Z Nano 3 Tank Is For
The Geekvape Z Nano 3 Tank suits vapers who want a compact 5ml tank on a 510 mod. Its B coils run from 10W to 58W. It’s the tank in our Aegis Mini 5 kit. For a bigger tank on Z coils, see the Z Subohm Tank 5.
Good to know: the Z Nano 3 takes Geekvape B coils, not the Z coils of the Zeus and Z Fli tanks. Our coil compatibility guide shows which coils fit each Geekvape tank and kit.
