4Color - Charger

4Color – Charger is a power adapter that uses different colours to clearly display the battery status of the device that is being charged.

To check the battery and charging status of a mobile device, we usually have to “wake” the phone to look at the battery bar. This can be inconvenient when the user is stationed some distance away from the device and the charging dock. To make things more convenient, 4Color – Charger uses different colours to display the battery status boldly so that the user does not have to travel all the way to their device.

Moreover, a problem with previous power adapters is that they are sometimes difficult to remove from the wall socket. 4Color – Charger proposes a donut shape to give better grip when removing the adapter from the socket.
