MP1580
Troubleshooting
If TekCharge MP1580 does not power your portable device or charge the device battery, take
these steps:
1. Check the battery status to ensure that the AA batteries are good, or that the rechargeable
batteries are charged.
2. 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.
3. 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.
4. Verify that a battery is installed in the portable device as some devices will not function
without a battery installed.
5. Verify if your device is designed with charging circuitry that limits the input voltage. If so,
TekCharge MP1580 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 MP1580 may not be able to
power or charge the device.)
If TekCharge MP1580 shuts down after connection to your portable device:
1. Verify that the portable device does not require more than 1000mA. If so, DO NOT attempt
to charge your device using TekCharge.
