USB_PWR adapter
- USB_PWR connects a 2.1mm barrel, center positive, connector to a USB
Type A (host) connector. Allows a suitable +5V power source to be used as a
+5V USB power source. Provides over voltage, over current, and reverse
polarity protection, reducing the risk of damaging your USB powered device.
- Primarily designed to be used with Base2Designs SOLAR_CHRGR. Connects a SparkFun
Solar Cell to the
Base2Designs SOLAR_CHRGR USB input.
- Can also be used with SparkFun
Large Solar Cell to
charge USB devices directly. I have had mixed results in this
application. If the USB device has a charging current less than 300mA
then it should work fine. Successfully tested with a Motorola cell phone (after
D+ and D- shorted), and a Garmin GPS device. Does not work with
Apple IPod.
