The PS1 is the world’s first 2-in-1 double vape cartridge and concentrate bubbler. This battery can draw from both the cartridges simultaneously since it permits double cartridge usage. Its double feature allows you to mix two flavors or a wax coil for a unique vaping experience or simply double down on your favorite flavor for enhanced use. What’s more, the battery can even be adapted for single cartridge usage – it comes with a tiny adapter that you can simply plug in one of the inlets when you want to enjoy just one cartridge at a time. Its advanced design and functionality make it a must-have item for all vaping lovers.
