As amateur astronomers we seek dark skies which are often some way from sources of AC power. The most common way to power your telescope in these situations is to use a portable 12V battery pack, like the Celestron PowerTank, or to use power from your car’s battery via the cigarette lighter.
The Celestron Car Battery Adapter enables you to connect any Celestron computerised telescope to a DC power supply or car battery. Plug the round post into the 12V input jack on the drive base of your telescope* and insert the power connector into the cigarette lighter outlet in your car or on your power supply. The cord is 25 feet long, providing plenty of reach between your telescope and the 12V power source.
The barrel connector can be used with any telescope that uses a socket with an outside diameter of 5.5mm and an inner diameter of 2.1mm and is 'tip positive' polarity.
