solar power backpacking
How many volts / amps do I need to (constantly) a pair of small computer speakers?
I'm thinking of making a solar small speaker for my backpack, so you can listen to music without having to worry about batteries and such. What do I need to do something well? I have old computer small stereo speakers, a lot of spare headphones, and I can not find small panels of sunlight.
I would say not less than 5 watts, 10 watts in practice. The low voltage side of the amplifier is probably using 9 to 12V.
