Quick answer: The current official pages describe two distinct NEXA Ultra models. Original NEXA Ultra is documented with a 5 mL prefilled pod plus 15 mL e-liquid container, Clarilock and a 3D curved screen. NEXA Ultra II is documented with a 4 mL storage-cotton section plus a 16 mL Crystal Tank, a 900 mAh battery, and Light/Dark modes. VapeRisk has not tested either device side by side, so this page reports manufacturer statements rather than a performance winner.

The main difference is exact product identity
Search results and listings can blur the original Ultra, Ultra II and InvisaCloud edition. The safest check is not the shared 50K headline. It is the combination of exact model name, liquid architecture and version-specific fields.
If a listing combines Ultra II’s 900 mAh battery or Normal/Turbo language with the original Ultra’s 5 mL plus 15 mL record, pause. A family name is not a substitute for exact product identity.
What the original Ultra page states
Nexa’s current original Ultra page lists a 5 mL integrated prefilled pod, a separate 15 mL e-liquid container, Clarilock Structure, Crystal Tank, Flavor Booster and a 3D curved screen. It carries a 50,000-puff headline and lists a user manual in the package.
The page does not state battery capacity, charging, coil, nicotine strength or a Normal/Turbo split. It also does not provide a traceable method for the puff headline or its “up to 35% more puffs” marketing. Those points remain manufacturer claims or unknown fields.
What the Ultra II page states
The current Ultra II page lists a 4 mL storage-cotton section, a 16 mL Crystal Tank, a 900 mAh battery and Light/Dark display modes. It says that pressing and holding for three seconds enters Dark Mode. The page publishes 50,000 puffs in Normal Mode and 30,000 in Turbo Mode as manufacturer headings.
The exact page does not state charging, coil, nicotine strength, airflow behavior, flavour result, leakage result or runtime. The two puff headings do not establish what an individual sample will deliver.
What this comparison cannot decide
Choose only after matching the exact model name, packaging and components to the appropriate manufacturer record. This comparison does not determine which version performs better, lasts longer, tastes better or suits every buyer.
- It is not a side-by-side VapeRisk test.
- It does not convert puff marketing into a measured result.
- It does not infer missing specifications from another family member.
- It does not establish authorization or legality for every market.
How to read the puff claims
Both pages use a 50,000-puff headline, while Ultra II separately publishes 30,000 for Turbo Mode. That is evidence that mode can change the manufacturer’s own estimate. Neither page captured for this comparison supplies a disclosed draw protocol or independent test.
Use Battery Capacity vs Puff Count and the Claimed vs Measured dataset to see how VapeRisk separates marketing claims, component markings and actual measurements.
Authenticity and market checks
- Open the official page for the exact Ultra version.
- Match the product name, liquid structure, battery and mode wording.
- Use Nexa’s official verification page and preserve the result.
- Keep the seller, invoice, package and verification record.
- Check exact product requirements in the destination market.
A successful verification result can support authenticity. It does not prove condition, market status, puff life or performance. For UK single-use rules, use the disposable-vape ban guide.
