I already had all the Solar stuff for my offgrid camping trips and back up power.
The BitAxe is $150 USD
The Jackery 240 was $200 … purchased 5 years ago.
The 100 watt solar panel was $100 .. purchased 5 years ago
I already run a small refrigerator and freezer with the jackery and 100 watt Solar Panel.
Thats nice.
I just need to design small scale Solar Powered Air Conditioning Unit and I will be all set.
Maybe try something natural.
