A 510 cartridge uses external heat from a rechargeable battery to vaporize the contents inside. They are designed to screw onto vape pens and use the internal battery to heat the atomizer, causing the coil inside the cart to heat up and vaporize the cannabinoid extracts. A 510 cartridge depends on a well-charged battery to provide enough heat to vaporize the cannabinoids stored inside correctly. Once you have screwed the 510 cartridge battery onto your vaporizer, trigger the vaporizer, and the coil inside the cart will heat up automatically and deliver the vapor.
