The CCell vapes are among the most popular vaporizer batteries available today.  One of the many features the CCell Palm, and other oil batteries are famous for is their amazing magnetic cartridge connection system.  Rather than the traditional method of twisting on your 510 threaded oil cartridge, CCell made their batteries magnetic.  In order to use the magnetic batteries with a traditional 510 cartridge, you will need the CCell Palm Magnetic screw adapter. The adapter screws onto the bottom of the oil cartridges to magnetically connect to the CCell Batteries or other bats that require a magnetic drop in adapter.
