The NEXA Ultra II brings a new level of engineering to high-capacity disposables, combining 20ml total e-liquid, a crystal clear visible tank, hidden storage reservoir, and a 3D curved screen for real-time monitoring. With Norm and Boost modes, leak-prevention tech, and a dual mesh coil engine, this device is built for flavor consistency and long-session reliability. In this NEXA Ultra II review, we break down what makes this 50K disposable one of the smartest releases from NEXA Vape.
What Makes the NEXA Ultra II Stand Out
Ultra-Portable Design with 3D Curved Screen
Despite its endurance-focused build, the Ultra II is compact, lightweight, and comfortable in the hand. The 3D curved display gives you live readouts for battery, puff mode, and e-liquid visibility - something rarely found in disposable vapes.
Crystal Tank + Hidden Storage Reservoir
The standout innovation is its dual-stage tank system:
-
a 16ml crystal tank that’s fully visible,
-
and a 4ml internal cotton reservoir hidden underneath.
Even when the visible section looks empty, you still have 4ml left - eliminating premature replacements.
NEXA Ultra II Specs & Performance
Norm & Boost Modes
The NEXA Ultra II disposable vape supports two performance settings:
-
Norm Mode: up to 50000 puffs of smooth, steady output.
- Boost Mode: up to 30000 puffs with warmer vapor, faster saturation, and more intense clouds.
This gives vapers flexibility to shift between chill daytime sessions and high-impact draws.
Battery & Charging
Powered by the 900mAh rechargeable battery, the device supports all-day use and charges quickly via Type-C. Lightning-fast charging gets you back to vaping with minimal downtime.
Dual Mesh Coil + Airflow Control
The dual mesh coil design boosts surface heating for sharper flavor definition and consistent vapor delivery. Meanwhile, the bottom-adjustable airflow lets you switch between tight MTL pulls and airy DTL inhales.
Tank System & Juicy-Lock Technology
16ml Crystal Tank with Click-to-Install Mechanism
The transparent tank uses Juicy-Lock, a smart click-to-install feature. Once attached, it unlocks the liquid flow automatically - zero mess, zero hassle.
4ml Internal Cotton Reservoir Explained
This hidden reservoir absorbs and stores extra e-liquid, feeding the coil when the top tank runs low. It maximizes longevity and ensures flavor does not drop off over time.
Leak-Prevention & Flavor Consistency
The sealed structure prevents leaks while supporting smooth wicking. Flavor stays clean, saturated, and stable from full tank to final puffs.

Real-World NEXA Ultra II Review
Flavor Delivery & Vapor Performance
The flavor is punchy, saturated, and clean thanks to the dual mesh coil and stabilized e-liquid flow system. It performs equally well in both Norm and Boost modes.
Tank Behavior – Crystal vs Storage Reservoir
Even when the crystal tank appears empty, flavor remains rich due to the hidden 4ml storage reservoir - no burnt hits, no dry wicking.
Battery Life & Boost Mode Trade-Offs
Battery life is excellent for a 900mAh cell, although Boost mode reduces total puff count - expected for higher wattage output.
Who the NEXA Ultra II Is Best For
Long-Session Users Wanting Maximum Endurance
Ideal for vapers who want weeks of use from a single disposable.
Vapers Who Prefer Smart Design & Visible Tank Systems
Perfect for users who want transparent tank monitoring, screen data, and adjustable performance.
Final Verdict
The Ultra II by NEXA stands out as a smart, flavor-focused, long-lasting disposable with premium engineering. With a crystal tank system, hidden reservoir, Boost/Norm modes, and dual mesh coils, it delivers consistency and customization rarely found in the disposable category.
