Celestron PowerTank Lithium Pro power supply

The Celestron PowerTank Lithium Pro is a high-capacity, portable LiFePO4 power bank designed for more demanding use. It keeps a computer-controlled telescope mount running for up to 17 hours whilst simultaneously charging a mobile phone or other USB devices, making it ideal for use at remote astrophotography sites, on camping trips and as an emergency power supply.

Connections for telescopes, car battery devices and USB devices

The power supply has a 12 V DC 5 A connection for the telescope, and the required Celestron cable is included. It also features a 12 V DC 10 A car battery connection and two 5 V USB ports, one of which delivers 2.1 A and the other supports fast charging. Using the two 2-inch straps supplied, the unit can be secured to the tripod leg, keeping it out of the way whilst observing.

White and red LED lights

On the side of the device is an LED light panel that emits either bright white light or red light, which preserves night vision. The red light is ideal as a safety light for stargazing events, whilst the white light can be used to tidy up the observation site at the end of the night. During a power cut, the bright light is sufficient to illuminate an entire room.
