Troubleshooting
If myPower GO does not power your portable device or charge the device battery,
take these steps:
1. Ensure that the AA batteries are charged.
2. Check that the input/output cord is connected to both myPower GO and the
portable device, and that the adapter plug fits snugly into the power jack on your
portable device. If not, try another adapter.
3. Verify that the polarity of the device power jack is center positive. If the polarity is
center negative, do not power the device with myPower GO as it does not support
center negative.
4. Verify that a battery is installed in the portable device as some devices will not
function without a battery installed.
5. Verify if your device is designed with charging circuitry that limits the input
voltage. If so, myPower GO may not be able to power or charge the device.
(For example, if a device is designed to accept only a 4.2V input, then myPower
GO may not be able to power or charge the device.)
