The refill geek bar pulse x is designed as a disposable vape, so it isn't intended to be refilled. Like other disposables, it comes pre-filled with e-liquid and a built-in battery that lasts until the liquid is used up or the battery dies. Refilling a disposable vape like the Geek Bar Pulse X can be tricky and isn’t recommended, as they are made for single-use and don’t feature a refillable chamber.

If you're interested in a similar device that's refillable, you might want to look into pod systems or refillable vape kits that offer similar ease of use with the flexibility to refill.
