Any unregulated power source (battery pack, solar cell, or power adapter) can be connected via the DC power adapter port of the Xplorer GLX (PS-2002) as long as the input voltage is within the range of 11 to 17 VDC. The recommended external voltage is 15 VDC. As the input voltage approaches the lower limits of this range, the rate of battery charging will diminish. Input voltages in excess of 17 VDC will damage the interface.
The power connector to the Xplorer GLX (PS-2002) is a center-positive 4.75 mm (OD) x 1.7 mm (ID) barrel connector as shown below. The nominal length for the barrel connector is 8.5 mm (See below). Care should be taken not to exert too much force on the connector when placing it into the power receptacle of the Xplorer GLX.
