N Remember to choose shell color ... an oversight on my part I, who works in the "Not always clean" ... it is missed for the white hull. otherwise 4400mA certainly takes better load than that of origin ... and therefore also charges 2 times slower. No more fear of falling into battery bay with his smart phone. It would very sensible for the manufacturer to specify the hours mA charger to avoid damaging the battery (I load with du1000mA) I will update this criticism by seeing if it takes time ds ca ... I should go the expense of the 25/30% and 90% stoppevers .... it every 2 days. if a last detail: The big shell provides better grip .... but fixing car becomes limited because of the shell width .... can not have tt.
