Charging the Extended Battery
1. With MP3450-10 connected, charge MP3450 as described earlier. Both batteries will be charged at the
same time (in parallel).
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 3.5 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 will not be
able to charge the device. However, in most but not all cases, MP3450 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, unlock the voltage lock (if in the locked position),
and change the voltage as required. (Please ensure the cable is unplugged from the portable
device while changing the voltage.)
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.)
