The power connector for the AirLink 2 is a USB mini "B" connector.
The recommended power solution is to use the PS-2574 (for North American power jacks)). This power connector receives the USB A connector from the cable that ships with the PS-2010.
If you choose not to use the PS-2574, the USB A end of the USB cable that ships with the PS-2010 can be used with any standard USB charging source. This is a common power connection standard for many cellphones and Bluetooth devices. To extend the usable collection time in the field for the AirLink 2, you can connect the AirLink2 to a portable cellphone charger that provides 5 VDC. The AirLink 2 can use an input voltage from 4.3 to 5.5V.
The AirLink 2 will draw a maximum of 400 mA from a charger or USB connector.
The SPARKlink Air can be charged through the USB connector by connecting this to a cell phone charger (hardwired or portable). The SPARKlink Air can also be charged through the dedicated charging port (5VDC, 2-3A, 1.35X3.5X9.5mm straight output plug, center positive). If you find the SPARKlink does not respond through charging through the USB port, please charge the device through the dedicated charging port.
