to provide power through the USB port .

as you would normally . While connected,
TekCharge will power and/or charge your device .

If TekCharge does not power your portable device or charge the device battery, take these
steps:
1 . Check that the input/output cord is connected to both TekCharge and the portable device,
and that the adapter plug fits snugly into the power jack on your portable device . If not,
try another adapter .
