Performance
Lost Angel Sphere wins on performance, driven mainly by its puff count of 35000 versus 25000 puffs for Geek Bar Pulse X. That gap of 10000 puffs is significant for anyone trying to get more use out of a single device, and it’s the clearest performance differentiator between the two.
Battery
Lost Angel Sphere also takes the battery category, with a 1000 mAh cell compared to the 800 mAh battery in Geek Bar Pulse X. That’s a 200 mAh advantage, which lines up with its higher puff count and suggests it’s built to last longer between charges or replacements. Lost Angel Sphere is also listed as rechargeable, though Geek Bar Pulse X doesn’t state this either way, so that specific point isn’t a fair comparison.
Convenience
Geek Bar Pulse X wins on convenience, largely thanks to its adjustable airflow, a feature Lost Angel Sphere doesn’t offer. Being able to tune the draw adds flexibility for users who prefer a tighter or more open pull, and both devices otherwise match on having a display, so airflow control is the deciding factor here.
Value
Value comes out as a tie. Geek Bar Pulse X offers a much larger flavor lineup at 50 count versus 26 count for Lost Angel Sphere, but that’s balanced against Lost Angel Sphere’s higher puff count and bigger battery. Neither product clearly outweighs the other once puffs, battery life, and flavor variety are all factored in.
Geek Bar Pulse X suits vapers who want control over their airflow and a much wider range of flavor options to choose from.
Lost Angel Sphere suits vapers who prioritize a longer-lasting battery and a higher overall puff count from a single device.
The verdict
Neither device sweeps the comparison. Lost Angel Sphere has the edge in puff count and battery capacity, making it the stronger pick for raw longevity, while Geek Bar Pulse X counters with adjustable airflow and a much larger flavor selection, giving it the convenience win. Value is a wash once those trade-offs are weighed against each other, so the right choice comes down to whether longer battery life or draw control and flavor variety matter more to you.
