Both the iJOY XP50000 and the NEXA Ultra 50K Disposable promise the same 50000-puff rating, putting them in direct competition on paper. The real question is whether the differences in battery size and unlisted specs are enough to separate them.
This comparison sticks strictly to the confirmed specs and review notes for each device, calling out where the data simply is not there to make a fair call.

Performance
Performance ends in a tie. The iJOY XP50000 lists a 22 W max output and a dual 0.4ohm mesh coil, while the NEXA Ultra 50K Disposable only states “dual mesh coils” without an output figure or resistance value. Both share the same 50000-puff count and adjustable airflow, but with the NEXA’s coil and output details not stated, there isn’t enough matching data to declare a performance edge either way.
Battery
Battery is also called a tie despite the iJOY XP50000 having a higher-capacity 1000 mAh cell compared to the NEXA Ultra 50K Disposable’s 900 mAh. Both devices are rechargeable via USB-C, so the practical experience of topping up is the same even though the iJOY carries more battery capacity on paper.
Convenience
Convenience is a tie as well. Both the iJOY XP50000 and the NEXA Ultra 50K Disposable include a display, adjustable airflow, and USB-C charging, giving users the same basic control and monitoring features on either device.
Value
There isn’t enough evidence to call a value winner. Pricing isn’t part of the supplied facts, and key specs like the NEXA’s max output and flavor count are not stated, so cost-per-feature can’t be reasonably judged here.
The iJOY XP50000 suits buyers who want a higher-capacity battery and clearly stated performance specs like max output and coil resistance.
The NEXA Ultra 50K Disposable suits buyers focused on the same core puff count and convenience features who aren't concerned about unlisted output or flavor details.
The verdict
Neither device comes out ahead across the board. The iJOY XP50000 has a documented edge in battery capacity and offers more transparency with its stated max output, coil resistance, and flavor count, while the NEXA Ultra 50K Disposable matches it on puff count, rechargeability, airflow, display, and charging port without providing the same level of spec detail. With value impossible to assess from the given facts, the choice comes down to which device’s stated specs matter more to the individual buyer.
