For the trouble-free operation of all instruments using a car battery or power tank with cigarette lighter socket
Most telescopes can be fed power using a car battery attached to a cigarette lighter, instead of the standard intended battery solution. In this way you can operate your instruments from your car’s cigarette lighter. Power tanks also have such a socket and deliver 12 volts.
The cable is compatible with all Skywatcher, Celestron and Orion telescopes.
