Questions about this item

How long will two AA batteries actually keep my phone running through the USB port?

Runtime depends on the batteries used and the phone's draw; fresh alkaline AAs typically deliver one partial charge for a smartphone.

What does the USB port's output limit mean for charging speed?

The port supplies standard 5 V USB power capped by the AA cells' current ability, so charging is slower than a wall adapter.
