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.)
1. With the unit upside down, push down on the lever above
the USB port, slide the battery cover in the direction of
the arrow, and then lift the cover to remove (Fig A).
2. Insert the batteries in the directions indicated.
If using only two batteries, install the pair in
the first two slots on the left or right (Fig B).
3. Replace the cover.
Using TekCharge MP1550
TekCharge can be used to power or charge any portable device that requires 5V or less. If your device
has a DC jack with center negative polarity, do not power the device with TekCharge as it does not
support center negative polarity.
TekCharge MP1550 doubles as a battery charger for two or four AA rechargeable batteries. When the
batteries are empty, you can recharge the batteries without removing them from TekCharge MP1550.
