Need a 5V adapter to charge your power bank or Android phone? Or maybe the famous Raspberry Pi series? This adapter comes with USB type A receptor, get your preferred USB cable and power up the target device. One of the special features of this adapter is the maximum output current is 2.5A which is nice for the Raspberry Pi series :)
This adapter is suitable for 3D Pen (5V version) too, tested by our internal team.
Note: From our internal test, this adapter can deliver up to 2.5A of current continuously for 1 hour and more. We stress the output with 2 ohm of high power load, it will get warm, but survive :). But voltage will drop if the USB cable is long, so try using a short cable if you need high current.
