Heading back to school in a month, and as I have a black adidas backpack, I thought of adding a solar panel on the back with a flap to cover/protect it when not needed/wanted. My ultimate goal was to build a peltier element can cooler, but I see most peltier units draw 3-6 amps and most small solar panels produce a max of 100 or 200 mA in the sun. My question is they sell those $15 USB can coolers that have to operate under an amp. How do they work?
(I go to a hippy liberal arts school, I am the total opposite (got into electronics with guns), but it wouldn't look out of place)
Any advice? I may decide not to be ecofriendly and just aid 4 rechargable batteries.
