At a Glance
The Geekvape Z Nano 3 Tank is a 5ml sub-ohm atomizer built around a push-to-refill top (the cap stays attached so you never lose it), leak-resistant top airflow and Geekvape’s B-series coils for rich DTL vapour and balanced RDL. It is the stock tank on the Aegis Mini 5 kit but fits any stable 510 mod. Full details are on the Geekvape Z Nano 3 Tank product page.

Push-to-Refill, Never Lose the Cap
The standout here is the refill method: a push-to-open top that stays hinged to the deck, so the cap can’t be misplaced mid-refill. It is a genuinely cleaner, simpler, more hassle-free way to fill than a cap you unscrew and set down somewhere, and combined with the 5ml capacity it means fewer, tidier top-ups.
Top Airflow and Leak Resistance
Air enters from the top rather than the base, which is Geekvape’s approach to keeping the deck dry and cutting leaking during everyday carry. The airflow is adjustable, so you can tailor each draw — from more restricted to freer — and the top-airflow path also supports consistent, long-lasting flavour on the B-series coils.
B-Series Coils: DTL and RDL
The Z Nano 3 runs Geekvape’s B-series: the pre-installed B0.2 Boost coil lives at 50–58W for rich direct-lung vapour, while the spare B0.4 Boost (25–35W) suits a balanced RDL draw. A choice of two bore sizes on the 510 drip tip adds another easy way to shape the hit without changing hardware.
What’s in the Box
- Z Nano 3 Tank with B0.2 coil pre-installed, plus a spare B0.4
- Spare (wider-bore) drip tip and spare glass tube
- Coil tool, manual and warning/info card
Fit and Compatibility
A standard 510 connector means it is not locked to one device, though at φ28mm it wants a 28mm-or-larger platform to sit flush — it is the natural pairing on the Aegis Mini 5 mod and kit, and works on other roomy 510 mods.
Pros and Cons
- Pros: Push-to-refill with attached cap; 5ml capacity; leak-resistant top airflow; two B-series Boost coils included; two bore drip tips; universal 510; DTL + RDL range.
- Cons: 28mm footprint can overhang slim mods; DTL-focused, so not a tight MTL tank; B coils are a consumable.
Verdict: Who Is It For?
