Loading... Please wait...The car charger allows you to charge your personal vaporizer battery while you’re on the move! The car charger plugs directly into a standard car power socket. One end of the USB charger plugs into the car charger and the battery is screwed into the other end via a line charger. USB line chargers are sold separately. Can be used for Ego or 510 Batteries, depending on what you own. The role of the USB line charger is to regulate the voltage depending on the different MAH of your battery. So a car charger adapater is universal but the line charger is tailored to either 510 or Ego Batteries.
