Qi Wireless Charger Transmitter

I’ve just bought a Qi Wireless Charger Transmitter and was hoping to use it with my Nokia Lumia 830 (which is capable of being charged wirelessly). When I plug the unit into a USB transformer, nothing happens and the phone does not detect it. When I plug the unit into a PC, nothing happens either.

Are there any visual indicators on the board when it is powered up?
Should the PC detect it as a USB device?

Any help would be appreciated.


Good news! The Nokia Lumia 830 is compatible with the Seeed charger.

I removed the back off the phone and cleaned the terminals. When I put the phone on the pad I got a red LED flash and an audible alert too.

I would like to suggest that Seeed considers having some kind of indicator to show that the device is alive.
