The active holder charges your battery when it is in the holder. The charging device connects to the unit automatically when you put the unit in the holder. The holder is attached onto a tilt swivel and can be adjusted in order to avoid light reflection. Connects to the vehicle's cigarette lighter socket, 12/24 Volt. Attach onto a ProClip Mounting Platform. Easy-switching system: The easy-switching system enables you to upgrade the holder only, and keep the installed cables. It saves you a lot of time! When upgrading to a new device, you do not longer need to make a full installation. Same goes for maintenance in case of warranty or damage. You simply disconnect the holder from the charging cable via the Molex 6-pin quick connector, and then connect the new holder. The switch is done in a few seconds.
