The iJOY XP50000 and Lost Mary Viz are both high-puff-count disposable-style vapes aimed at buyers who want long usage between charges or replacements. On paper they share some similarities, like rechargeable batteries and mesh coil setups, but they diverge in areas like battery capacity, control features, and flavor variety.
This comparison sticks strictly to the specs and category results provided, calling out where the data supports a clear distinction and where it does not.

Performance
Performance ends in a tie based on the available data. The iJOY XP50000 lists a max output of 22 W, while the Lost Mary Viz does not state a wattage figure at all, making a direct output comparison impossible. Both use dual mesh coil setups, though the iJOY XP50000 specifies a 0.4ohm resistance while the Lost Mary Viz simply says “dual mesh coils” without further detail. With coil specs and output only partially comparable, there isn’t enough matching data to separate the two on performance.
Battery
Battery is marked a tie at the category level, but it’s worth noting the individual spec row: the iJOY XP50000 carries a 1000 mAh battery versus 850 mAh for the Lost Mary Viz, a real difference in raw capacity. Both devices are rechargeable, which levels the field somewhat since neither requires disposal once the battery is drained. The category tie likely reflects that battery capacity alone doesn’t fully determine real-world battery life, especially with puff counts factored in — the Lost Mary Viz actually claims a higher puff count (55000 vs 50000, though that row is also a tie) despite its smaller battery.
Convenience
The iJOY XP50000 wins convenience, and the spec table backs this up clearly. It offers adjustable airflow, which the Lost Mary Viz does not, giving users more control over draw resistance. It also includes a display screen, a feature absent on the Lost Mary Viz, which can help users track battery life or usage at a glance. These two features together give the iJOY XP50000 a tangible edge in day-to-day usability.
Value
Lost Mary Viz takes the value category, largely on the strength of its flavor lineup: 15 flavor options compared to 10 for the iJOY XP50000. More flavor variety gives buyers more choice without needing to purchase a different device, which is a reasonable basis for a value edge even though pricing itself isn’t part of the supplied facts.
The iJOY XP50000 suits buyers who want a larger battery along with hands-on control through adjustable airflow and a usage display.
The Lost Mary Viz suits buyers who prioritize a wider range of flavor options over device controls.
The verdict
Neither device comes out ahead across the board, and the category results reflect genuinely different strengths. The iJOY XP50000 stands out for its larger battery and added convenience features like adjustable airflow and a display, while the Lost Mary Viz counters with a wider flavor selection that earns it the value win. Performance and battery are effectively even given the gaps in comparable data, so the right pick depends on whether a buyer prioritizes hands-on control and battery capacity or flavor variety.
