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 3.5 Amp. (3.5 Amp

for both MP3300 and MP3400). 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. Verify that the device does not require more than 14V (MP3300) or 19V (MP3400). If the device

requires more, MP3300/MP3400 will not be able to charge the device. However, in most but not all

cases, MP3300/MP3400 will be able to power 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 device power jack is Center Positive.

If the polarity is Center Negative, please contact [email protected]

for assistance.

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. (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 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 may not be able to power or charge the device.)
