You *built* one. I'm impressed. Can you point me to directions and how to do that. (Not that I'll do it myself, that's what electrician sons are for).
You basically miniaturize a home solar power system ^__^
Solar Charge Controller (don't need a high amp one 10A should do)
12v Solar panel At least 20w, 40w better anything bigger and it will be too big to be inconvenient...
Battery Bank Preferably AGM (can use lithium but it will raise the price of the whole project significantly).. I used 3x 10AH SLA AGM's
Inverter at least 200W
Dual Plug 110v Power/USB can get separate to lower costs but got them together for convenience...
Plastic Electrical Enclosure
Outdoor waterproof Electrical Plate.
Voltage meter so you know when to charge...
Various Switches so you can turn off each component
2x 12v Sockets (One for power one for solar panel)
Male 12v Connector
Electrical Solder...
Wire Connectors.
Heat Shrink.
Electrical Tape
110v-12v SLA Charger so you can charge off grid
Power Socket for 110v plug..
Cord for socket you got...
Red and black wire....
I think that's it... That case is quite literally jam packed lols
