I bought a generic MP3 player (something like this one) and a USB charger like this one.
When I plug the charger into the player, the player screen lights up for a few seconds, then goes out again. There is no indication that the player is being charged via the small battery charging icon on the screen.
I want to be able to charge the player using something other than my PC. What might be going on and how can I fix it?
Thanks and appreciation!
