PocketScan can be charged using any standard USB cable with a micro adapter. It is best to use a power supply to charge which will take around 2-3 hours to fully charge PocketScan. It is also possible to charge PocketScan by plugging the USB cable into a laptop USB port, however, it will take longer.
While charging the red LED will be constantly on. The charging process is finished when the red LED turns off. Please note that it is not possible to scan, while charging.
