However, i'm not sure if a single button cell would be able to charge the player for more than 1 full charge. As these button cells are about 220-230mAh.
i'll try to get the current charger working with perhaps 4xAA cells, 6V to 5V, not as much losses as compared to the 9V cell.
The current 9V cell managed to charge my nano-clone from a flat battery to around 1/3 capacity in about 15mins. So an estimated full charge would take about 45mins or so.

hello, the 80% of charge of a litium poly battery can be reach in aprox 25 mins but a full charge may take 2 hours, i really just am learning why but
