You can use myPower for iPhone to power your iPhone,
or to charge your iPhone while connected to external
power. When powering iPhone, myPower for iPhone will
bypass the iPhone battery to power a connected iPhone,
thus extending the overall life of the iPhone battery.
The battery will not charge iPhone unless connected to
an external power source.
myPower for iPhone is charged
in two ways: by connecting to a USB power adapter,
or to a USB port on a computer. The included USB cable
is used to charge the device. If you are using an iPhone-compliant
USB power adapter, you also may charge your iPhone
at the same time by inserting the iPhone in the case
while connected to an external power source.
As a bonus
feature, myPower for iPhone doubles as a dock to sync
iPhone to your computer when connected via the USB
cable. In this case, myPower for iPhone will both sync
and charge iPhone.
