Use an active holder for your tablet while driving and you will always have a freshly charged battery! The holder provides a neat and comfortable installation - safe and convenient. The holder is equipped with a cig-plug for connection to the vehicle's 12 Volt socket. If you have a vehicle with USB interface, you can disconnect the cig-plug from the holder's cable in order to get a USB-cable which you can connect directly to the USB interface in your vehicle.
