Keeps only 9 months at approximately max. 20 charging cycles; no 2 devices loaded

On the battery selbs a higher capacity is provided but is of little use if it just so survives the warranty period, since about 10 hours light while only 3 of 4 indicator lights. I thought my tray to load the battery to empty and then reload, at 30% state of charge at the tray was closing, so basically after a few charging cycles battery in Ar ..... Incidentally, the shop will remain off if I connected phone at 1 Ampere and tray at 2 amps, then vozu 2 times USB output ????
