QUAD CARTRIDGE

Most 510 batteries hold one cartridge. A quad cartridge battery holds four — and can fire all of them at once.

That is the whole idea behind THE SHLUMPT BOX. Load up to four 510-thread cartridges, run them on their own or together, and stop unscrewing carts every time you want to switch between them. A 1500mAh cell keeps all four supplied through the day, and universal 510 threading means the cartridges you already own will fit.

Quad-cartridge devices sit in a category of their own. Dual and triple cart batteries have been around for years, but carrying four at once changes how the device gets used — it becomes the only battery you need on you, rather than one of several.

Every SHLUMPT.CO order is designed and shipped from Los Angeles and backed by a limited warranty covering manufacturing defects. Browse the quad cartridge range below.
