Troubleshooting
If TekCharge MP1800 does not power your portable device or charge the device battery, take these steps:
1.Check that the input/output cord is connected to both TekCharge and the portable device, and that the adapter plug fits snugly into the power jack on your portable device. If not, try another adapter.
2.If connecting TekCharge to a device with a DC jack, verify that the polarity of the device power jack is center positive. If the polarity is center negative, do not power the device with TekCharge as it does not support center negative.
Center Positive | Center Negative |
3.Verify that a battery is installed in the portable device as some devices will not function without a battery installed.
4.Verify if your device is designed with charging circuitry that limits the input voltage. If so, TekCharge MP1800 may not be able to power or charge the device. (For example, if a device is designed to accept only a 4.2V input, then TekCharge MP1800 may not be able to power or charge the device.)
