Troubleshooting
If myPower ALL Plus 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 4.0 Amp. If the device consumes
more than the maximum provided by myPower ALL Plus, the device will shut down when turned on and
cannot be powered and/or charged by myPower ALL Plus.
2. Verify that the device does not require more than 19V. If the device requires more, MP3450 R2 will not be able to
charge the device. However, in most but not all cases, MP3450 R2 will be able to power the device.
3. View the remaining battery capacity. If it is below 25%, recharge myPower ALL Plus.
4. Check that the output cord is connected to both myPower ALL Plus 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 device power jack is Center Positive. If the polarity is Center Negative, please
contact support@tekkeon.com for assistance.
6. Check that the output voltage for your portable device matches or is just below the output voltage set on
myPower ALL Plus. If the output voltage is not correct, unplug the output cable from the portable device, and
change the voltage as required.
7. Verify that a battery is installed in the portable device as some devices will not function without a battery
installed.
8. Verify if your device is designed with charging circuitry that limits the input voltage. If so, myPower ALL Plus
may not be able to power or charge the device. (For example, if a device is designed to accept only a 10.2V
input, then myPower ALL Plus may not be able to power or charge the device.)
