Waterproof Portable Power Station

This power station was designed to prevent a water dish for pets from freezing all winter long. In a location without power and being energy conscious, a 3W submersible pump was incorporated rather than a heating element. The circulating water resists freezing and the low wattage pump helps the battery last for a very long time, great for those long winter periods with suboptimal solar production. Waterproof connections were added to the enclosure to make sure that everything stays nice and dry.
