The NEXA Ultra II is the updated version of the original NEXA ULTRA 50000, bringing several refinements to a high-capacity disposable vape design. Rather than completely changing the formula, NEXA has focused on improving the areas that matter most, including the device’s size, assembly system, airflow, charging and overall convenience.
According to the Vaping360 review, the Ultra II combines a 20 mL total e-liquid capacity, a 900 mAh rechargeable battery, dual-mesh coils and two power modes. It also introduces NEXA’s Juicy Lock system, which makes connecting the two sections considerably simpler.
The device is designed around a transparent tank, allowing users to see the remaining e-liquid instead of relying entirely on an indicator. It also adds a stealth mode that can turn off the decorative LED effects while retaining the battery display.
What Is the NEXA Ultra II?
The NEXA Ultra II is a two-part, rechargeable disposable vape that follows the original ULTRA 50000. The device consists of a prefilled pod section and a battery section.
The pod contains 16 mL of e-liquid, while another 4 mL is held within the device’s internal cotton system, giving the product a stated total capacity of 20 mL.
One of the biggest changes is the updated Juicy Lock assembly system. Instead of dealing with the more complicated setup associated with the original ULTRA, the two sections are designed to snap together. This makes the initial setup straightforward and helps keep the liquid sealed before activation.
The device is available in a range of flavor profiles, including fruit, ice, candy and mint-inspired options.

These specifications make the Ultra II a feature-rich entry in the high-capacity disposable category.
Design and Build Quality
The NEXA Ultra II retains the futuristic appearance associated with the ULTRA range but comes in a more compact body. Vaping360 notes that it is approximately 9.7% shorter than the original ULTRA, making the updated model feel somewhat easier to carry.
One of the most noticeable design elements is the transparent tank. This allows the remaining e-liquid to be viewed directly, which can be useful because the tank’s appearance gives a clearer indication of how much liquid remains.
The glossy black exterior also gives the device a modern appearance while reportedly resisting fingerprints better than many other glossy disposable devices.
The mouthpiece has also been updated with a softer, more bite-friendly material, an improvement over the harder mouthpiece used on the original ULTRA.
Juicy Lock System
The Juicy Lock system is one of the most important changes in the NEXA Ultra II.
The original ULTRA used a two-part design, but its assembly could be somewhat confusing. The Ultra II simplifies this process. After removing the packaging spacer, the two sections can be pressed together until they click into position.
This approach provides a cleaner setup while keeping the liquid sealed before the device is assembled.
The system also fits with the overall design philosophy of the Ultra II: preserve the high-capacity concept of the original while making the experience simpler and more user-friendly.
Performance and Airflow
Performance is another area where the NEXA Ultra II aims to improve on its predecessor.
The adjustable airflow allows the draw to move from a tighter mouth-to-lung (MTL) style toward a more open restricted-lung experience. Vaping360 describes the airflow as smooth and consistent across its range.
The device offers two power modes:
Normal Mode
Normal mode provides a more subdued and cooler experience. It is also associated with the device’s higher advertised puff count of up to 50,000 puffs.
Turbo Mode
Turbo mode produces a warmer and more intense draw, with stronger vapor and flavor. The advertised puff count drops to approximately 30,000 puffs in this mode.
The dual-mesh coil system is designed to provide consistent vapor and flavor delivery. According to Vaping360’s testing, activation was immediate, with a smooth draw and no reported popping, spitting or leaking during testing.
Actual performance and puff counts can vary depending on puff duration, frequency, power mode and other usage conditions.
NEXA Ultra II Flavors
The NEXA Ultra II launched with 15 flavors, giving users a selection across fruit, cooling and candy-style profiles. The flavors listed by Vaping360 include:
- Black Cherry
- Blueberry Watermelon
- Strawberry Ice
- Strawberry Mango
- Strawberry Colada
- Strawberry Banana
- Sour Apple Ice
- Miami Mint
- Lemon Frozen
- Blue Razz Ice
- BP
- Fcuking FAB
- Georgia Peach Ice
- White Gummy
- Watermelon Ice
Vaping360 specifically sampled Black Cherry, Blueberry Watermelon and Strawberry Ice. Black Cherry was described as moderately sweet with an aromatic cherry profile, while Blueberry Watermelon combined blueberry with a brighter watermelon note. Strawberry Ice blended strawberry with a moderate cooling effect.
Flavor preferences are naturally subjective, so the best option will depend on whether you prefer fruit, cooling, candy or sweeter profiles.
Battery and Charging
The Ultra II uses a 900 mAh rechargeable battery, slightly larger than the 800 mAh battery in the original ULTRA.
One of its notable advantages is fast partial charging through USB-C. Vaping360 reported that even a short charging session could provide a substantial amount of additional use, while pass-through charging allows the device to operate while connected to power.
A full charge takes longer than a quick top-up, but the rapid partial charging capability can make the difference less noticeable during normal use.
Display and Stealth Mode
The NEXA Ultra II includes an animated LED display that contributes to its futuristic appearance.
For users who prefer a more discreet appearance, the device introduces stealth mode. Holding the button for approximately three seconds turns off the main light effects while still allowing the battery percentage to be displayed.
This is a small but practical improvement over the original ULTRA, particularly for people who don’t want a bright animated display every time they use the device.
How Long Does the NEXA Ultra II Last?
The device is advertised with up to 50,000 puffs in Normal mode and approximately 30,000 puffs in Turbo mode. However, puff-count ratings are estimates rather than guarantees.
Battery life depends on how frequently the device is used and which power mode is selected. Vaping360 reported getting at least a full day of steady use in Turbo mode on a charge during testing, while quick partial charging provided several additional hours of runtime.
The transparent tank is particularly useful for monitoring e-liquid. When the visible tank appears empty, the device may still contain some liquid in its internal cotton storage, so the taste and vapor performance are better indicators of when the device has reached the end of its useful life.

NEXA Ultra II vs. Original ULTRA
The Ultra II is not a complete redesign. Instead, it takes the core features of the original and refines them.
The most noticeable changes include the smaller body, updated Juicy Lock system, 900 mAh battery, improved mouthpiece and stealth mode. At the same time, the transparent tank, dual-mesh coils and dual power modes remain central to the experience.
This makes the Ultra II more of an evolution than a completely new product.
Final Verdict
The NEXA Ultra II is an updated high-capacity disposable vape that focuses on refinement rather than dramatic change. Its combination of a transparent 20 mL liquid capacity, dual-mesh coils, adjustable airflow, two power modes and rechargeable 900 mAh battery gives it a feature set that stands out within the high-puff disposable category.
The Juicy Lock system is arguably one of the most useful improvements because it makes the two-part design much easier to assemble. The addition of stealth mode, the updated mouthpiece and the more compact body further improve everyday usability.
Overall, the NEXA Ultra II keeps the strengths of the original ULTRA while addressing some of its less convenient design elements. For adult users who are already considering a high-capacity rechargeable disposable, it is a model worth researching alongside comparable products.
