Try it for an hour and see what your battery level is presently shows. If it had drained, then switch to the 2amp port.
Thanks for the info. I'm puzzled, though, about where the current goes once the internal battery is charged up: Why would the phone keep drawing current if its battery is already full? Due to some impedance mismatch between the internal and the external batteries?
Also thanks for the tip on the
short angled cables. I'll find a micro USB-regular USB cable to connect the two.
