These scientific PHD Vaporizer Batteries from Pulsar fit most cartridges up to 11mm in diameter. A magnetic cart connector with universal 510 threading allows cartridges to be dropped into the battery's cart chamber, making it simple to switch out tanks. These unique batteries also function as a preheating device by pre-warming the entire Cartridge for optimal vaping performance.

The PHD 510 Battery features two dual-mode preheat modes. Cartridge preheat mode will indicate its function with a blue light and heats from the coil up for the first fifteen seconds. The Shell preheat mode, indicated with a green light, heats the entire unit for the next 15-45 seconds.
