Compare the GeekVape Z 5 and Zeus Z Nano 3 sub-ohm tanks on capacity, coil life, airflow, and size to decide which fits your vaping style.
Quick answer
Choose the Geek Vape Z 5 if you want longer coil life and a larger 5.5mL capacity for fewer refills. Choose the GeekVape Zeus Z Nano 3 if you prefer a compact 28mm tank with a 5mL capacity and push-to-open top fill.
Capacity and refill frequency
The Z 5 holds 5.5mL, while the Zeus Z Nano 3 holds 5mL. That half-milliliter difference is small, but over a day of vaping it can mean one fewer refill for the Z 5. The Z Nano 3's push-to-open top fill is designed for quick, clean refills when you're on the go.
Coil life and long-term cost
The Z 5 uses the upgraded Z XM Coil (BOOST VERSION), which Geek Vape rates for up to 60mL of e-liquid per coil. The Zeus Z Nano 3 uses B Series Boost coils, but the catalog does not state a coil life figure. If you vape heavily and want to minimize coil changes, the Z 5's rated coil life is a clear advantage.
Airflow and draw adjustment
Both tanks feature top adjustable airflow, which helps reduce leaks. The Z 5's leak-proof top airflow is designed to minimize condensation and spitback. The Zeus Z Nano 3 also has top adjustable airflow, plus a dual-bore 510 drip tip that lets you fine-tune the draw. If you like to experiment with different drip tips, the Z Nano 3 offers more flexibility.
Size and portability
The Zeus Z Nano 3 is a compact 28mm tank, making it a better match for smaller mods or for vapers who prioritize a low-profile setup. The Z 5's dimensions are not listed in the catalog, but its larger 5.5mL capacity suggests a slightly bulkier build. If pocketability matters, the Z Nano 3 is the safer bet.
Key trade-offs
- Capacity vs. size: The Z 5 holds 0.5mL more e-liquid but is likely larger; the Z Nano 3 is more compact but holds slightly less. Decide whether fewer refills or a smaller footprint matters more to you.
- Coil life vs. coil flexibility: The Z 5's Z XM coils are rated for 60mL, while the Z Nano 3's B Series Boost coils have no stated life figure but offer the same Boost compatibility. If you want a known coil lifespan, the Z 5 is the clearer choice.
- Airflow and drip tip: Both have top adjustable airflow, but the Z Nano 3 adds a dual-bore 510 drip tip for draw tuning. Choose the Z Nano 3 if you like to adjust your draw with different drip tips.
