I am considering buying a Mophie poortable batter for my D4 in case I ever need more juice than I have while out and about (like spending a day at Disneyland where the service blows and drains battery). It says you can choose to charge you phone up with 0.5Amp, 1Amp, or even 2Amps of current in order to expedite charging. This made me wonder, is it SAFE to charge a smartphone battery with such high amperage? Will I damage the battery or shorten it's lifespan at all?
