Will a USB Mp3 player charge with 5v and 88MA? Answered

Will a USB device Mp3 (usually 5v and 100-400 mA) player charge with 5v and 88MA? Will it take longer to charge? Or will it overload the charger and break something? Will a fluctuating amperage, always below the device's requirements, damage the device's LiPo battery?

Thank you! I'm going to make something cool!

it might... some devices are picky. try it.... but watch the charger, if it gets hot, it wont work. if it does work, the player would take longer to charge.

hmm... where do you get a device that puts out 88ma? that's a whole 440mw! it probably won't work, considering the fact that most devices have to switch modes in order to charge (if you connect the 88ma straight to the battery, it should charge)

I'm going out on a limb here but I'm thinking a hand-crank dynamo charger or something like that.

darrr...it's so obvious now you mention it. It might work - most charging circuits apply as much current as available up to a maximum...if less is available then they charge with less. SOME however, will poop the proverbial bed.

I'm making a solar charger. A 2" by 2" panel will put out 1 amp and 5 volts. I'm trying to make it as small as possible so i'm trying to find the best sized solar panels and what-not.

i would recommend charging a battery, then charge your MP3 player, then you can leave the battery to charge, and when you need to recharge, just connect the battery to your mp3 player
