It is sometimes difficult to determine how much current is your device using and how much current do you need. Of course you can use multimeter but in case you do not want to buy two USB connectors and connect multimeter between them for example using breadboard I would recommend you using ready to use solution called '''CHARGER Doctor'''. You can buy it from China on [http://www.ebay.com/|E-Bay] for approximately 2 USD including WorldWide shipping from many suppliers. | It is sometimes difficult to determine how much current is your device using and how much current do you need.
