If you are away from an AC power source, 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 Adaptor is the accessory required for connecting 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, giving you plenty of reach between your telescope and 12V power source.
The barrel connector can be used with any telescope that uses a receptacle with an outside diameter of 5.5 mm and an inner diameter of 2.1 mm and a “tip positive” polarity.
*For use with the following telescopes:
- NexStar SLT Series
- NexStar / GT Series
- CGEM Series
- CPC Series
- CPC Deluxe Series
