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 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. If the output voltage
is not correct, unlock the voltage lock (if in the locked position), and change
the voltage as required.
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.)
