Stanley 12V 44Ah Portable Astronomy Power Box / Field Battery

Stanley 12V 44Ah Portable Astronomy Power Box / Field Battery

Custom-built portable 12V power station, originally made for astronomy and telescope use.

I built this unit several years ago as a reliable field power supply for my telescope setup. It is housed in a heavy-duty Stanley rolling toolbox with wheels and extendable handle, making it easy to transport despite the weight of the battery.

Inside is a 12V 44Ah lead-acid battery, providing plenty of capacity for a typical night of observing.

Features:

12V 44Ah battery

Multiple protected 12V sockets

Suitable for powering telescope mounts

12V connection for dew-heater straps and other astronomy accessories

USB charging via 12V adapter

Digital display for monitoring power/current usage

Main ON/OFF switch

Additional connection points on the front panel

Heavy-duty Stanley toolbox with wheels and telescopic handle

Internal storage trays, useful for cables and accessories

6A automatic battery charger with crocodile clips included

The photos show the actual unit, including the internal battery and wiring. The phone shown in the photos is only to demonstrate the USB charging function and is not included.

This is a homemade/custom-built unit rather than a commercial power station, so it is best suited to someone familiar with 12V equipment.

Originally built for astronomy, but it could also be useful for camping, fishing, amateur radio, portable 12V equipment, emergency power, etc.

Used condition with normal cosmetic marks from use, but solid and practical.

Due to the size and weight of the battery, collection would be preferable.
