The CCELL® PALM Vaporizer Battery by Hamilton Devices is an excellent but discreet 510 battery, integrating a 500mAh rechargeable battery, self-adapted temperature settings, and is crafted with a quality circuit board with multiple protections. Measuring only 42mm tall, the CCELL Palm Vaporizer Battery houses an integrated 500mAh rechargeable battery within the aluminum alloy chassis. In addition, a proprietary chipset within carefully meters the battery life in a self-adapted fashion, outputting the ideal power levels to vaporize efficiently and effectively. Furthermore, the CCELL Palm fits neatly inside the hand, maintaining the modest and compact profile by recessing the 510 threaded port and offering a magnetic connection ring to facilitate a "quick release" connection.
