1.26w weather proof solar panel $30.00 (cabelas)
12v 7.5amp rechargeable sealed lead-acid battery $30.00 (radioshack)
12v socket $11.00 (walmart)
cooler $8.00 (walmart)
nuts/bolts $2.00 (walmart)
wire plugs $2.00 (walmart)
super glue $1.00 (dollar store)
w/tax around $90.00
Step 1: Cutting wires and holes
Step 2: Assembly
Next the 12v socket was threaded into place.
super glue was applied to the nuts and the 12v socket threading to insure vibration would not cause any thing to come loose.
After the glue set I crimped the wires from the panel and the 12v outlet to quick disconnect tabs.
the final step was dropping in the battery and plugging in the wires.
