Overview
TekCharge™ MP1550 takes advantage of AA batteries to provide emergency power to mobile phones,
smartphones, Bluetooth headsets, iPod/iPhone, MP3 players, PDAs, digital cameras, and more. This
small mobile charger includes a voltage regulator so it won’t harm your device or its battery. As an
added bonus, TekCharge MP1550 doubles as a battery charger, so you can charge your rechargeable
AA batteries as needed.
TekCharge connects to your device in two ways: you can use an adapter to connect to your device,
or you can use your USB device cable, bypassing the need for an extra adapter. Adapters for current
models of Blackberry and Motorola (mini USB), LG, Nokia, Samsung and Sony Ericsson mobile
phones are included with TekCharge MP1550. These same adapters also may work with your MP3
players, PDAs, portable media players and other small devices. If the extra adapter you need isn't in
the package, just go to www.tekkeon.com or call us at 888-787-5888 or 714-832-1266 to order more
adapters for a nominal fee.

Installing Batteries
TekCharge MP1550 requires two or four rechargeable or alkaline AA batteries, which are housed on the
bottom side of the unit. As TekCharge MP1550 doubles as a battery charger, rechargeable batteries can
be recharged in the unit when connected to a USB port on a computer
or power adapter. (Please note that alkaline and rechargeable batteries
should not be used together.)

Troubleshooting
If TekCharge MP1550 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.
Center Positive
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
MP1550 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 MP1550 may not be able to power or charge the device.)
