Troubleshooting
If myPower ALL does not power the portable device or charge the device battery, take these steps:
1. Verify that the current consumption of the portable device is not more than 4Amp. If the device
consumes more than the maximum provided by myPower ALL, the device will shut down when
turned on and cannot be powered and/or charged by myPower ALL.
2. If the device requires a charging voltage greater than 14V, verify that the total output power provided
by the device power adapter is not more than 64W. To do this, multiply the voltage by the amps
shown on the power adapter (Watt=Voltage x Amps). If the output power is greater than 64W,
myPower ALL MP3300 will not power or charge the device.
3. View the remaining battery capacity. If it is below 25%, recharge
myPower ALL.
4. Check that the output cord is connected to both myPower ALL and
the portable device, and that the adapter plug fits snugly into the
power jack on your portable device. If not, try another adapter.
5. Verify that the polarity of the portable device’s power jack matches
the adapter plug. In most cases, the polarity is center positive. In
this case, you must match the positive symbol (+) on the selected
adapter plug to the positive symbol (+) on the power output cord
as shown on the top right, and connect. If the polarity is center
negative, disconnect the adapter plug from the output cord and
reconnect the plug in the opposite direction as shown on the
bottom right.
6. Check that the output voltage for your portable device matches or
is just below the output voltage set on myPower ALL. If the output
voltage is not correct, unlock the voltage lock (if in the locked
position), and change the voltage as required.
