Portable power for Celestron telescopes

The Celestron 18774 PowerTank is a 12V rechargeable supply built for amateur astronomers who operate computerized telescopes or motor-driven mounts away from mains power. It also serves as a roadside emergency accessory with a built-in spotlight and booster terminals for weak vehicle batteries. The unit is not suited for users who need higher voltage outputs or AC inversion for household appliances.

Simple connection with protected outputs

Two 12V cigarette-lighter sockets accept standard telescope power cords, while 3V, 6V and 9V terminals cover smaller accessories. A built-in circuit breaker guards against overloads and short circuits, resetting automatically once the fault is cleared. The red filter cap on the LED spotlight preserves night vision during observing sessions. Users without 12V barrel or cigarette-lighter cables will need separate adapters.

Steady 7-amp-hour capacity for long sessions

The sealed lead-acid battery delivers a 7-amp hour rating, supporting typical goto mounts and tracking drives through an entire night of observation. Voltage remains stable under continuous motor load rather than sagging after a brief peak draw. Recharge between outings using the supplied charger; the pack is not designed for rapid cycling or high-current starting of large engines.
