Troubleshooting
If TekCharge MP1860A 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 tip.
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.
3. Verify that a battery is installed in the portable device as some devices will not function without
a battery installed.
4. Determine if your device is designed with charging circuitry that limits the input voltage. If so,
TekCharge MP1860A 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 MP1860A may not be able to power or
charge the device.)
If your iPad, iPhone or iPod does not sync while TekCharge MP1860A is connected to a
computer:
1. Ensure that TekCharge MP1860A is connected to your computer using a USB/Mini USB data
cable.
If TekCharge MP1860A shuts down for five seconds to five minutes after you connect a
device (or two devices at the same time):
1. Connect TekCharge MP1860A to the included USB power adapter or to your computer.
2. Check the power capacity on TekCharge MP1860A. If the battery is empty or too low, recharge
the battery.
3. If the TekCharge MP1860A capacity indicator is blue, check the connected device (or devices) to
ensure the total output current does not exceed 2.5A.
