Both the iJOY XP50000 and the NEXA Ultra 50K Disposable promise the same headline puff count, so the real differences come down to what’s under the hood and how each device is finished off.
This comparison sticks strictly to the confirmed specs, flagging where NEXA’s data sheet leaves gaps rather than guessing at figures.

Performance
On paper the two devices match on puff count at 50000 puffs each, and both offer adjustable airflow and a smart display, which is why performance is called a tie. The iJOY XP50000 does list a 22 W max output and a dual 0.4ohm mesh coil, giving buyers concrete numbers to weigh up, but since NEXA hasn’t published a comparable output or coil resistance figure, there’s nothing solid to set against it — so it can’t tip the category either way.
Battery
The iJOY XP50000 wins outright here, with a 1000 mAh battery against the NEXA Ultra 50K Disposable’s 900 mAh. That’s a straightforward 100 mAh advantage, and both devices are rechargeable via USB-C, so the extra capacity isn’t offset by any charging-method difference — it’s simply more battery to draw on between top-ups.
Convenience
Convenience comes out level. Both devices are rechargeable, both include adjustable airflow, and both feature a smart display, covering the main day-to-day usability points equally. Charging port details differ slightly in wording (USB Type-C versus USB-C) but functionally point to the same connector, so neither product pulls ahead.
Value
There isn’t enough evidence to call a value winner: no pricing is given for either device, and NEXA’s missing flavour count, output, and coil specs make a like-for-like value judgement impossible from the facts supplied.
The iJOY XP50000 suits buyers who want a larger 1000 mAh battery and fuller published specs, including max output, coil type, and flavour count, to compare before buying.
The NEXA Ultra 50K Disposable suits buyers happy to match the same 50000 puff count and core convenience features without needing every spec confirmed upfront.
The verdict
Neither device comes out as an all-round winner. The iJOY XP50000 has the clearer edge on battery capacity and also brings published figures for output, coil, and flavour options that let buyers make an informed choice. The NEXA Ultra 50K Disposable matches it puff-for-puff and ties on convenience features, but its thinner spec sheet means several categories simply can’t be judged. The right pick depends on whether you value a fuller published spec and larger battery, or are comfortable with a device where several details remain unconfirmed.
