FAQ for USB charging
0: Why is the USB port not charging my devices?
A: Make sure that the USB plug is firmly connected into both ports of the RT-4507 and your USB compatible
device and that the RT-4507 is plugged in to a power source as the USB charging ports will not operate
from the backup batteries.
Q: Why will my Nook/netbook device not charge when I connect it to the USB charger?
A: Even though it my be USB compatible, some devices, including the Nook and some larger tablets or
netbooks require a higher output to charge them than the 5V/1.0A USB port on the RT-4507. Please check
your device manufacturer's charging specifications as you may be required to only use the charger
