| In 2010 the WPC launched **Qi Version 1.0**. This version supported three transmitter types: **single coil, coil arrays, and moving coils**. The coils allowed power transmission of up to **5W**. However, its design flexibility was limited, meaning manufacturers could only optimise charging performance by tweaking receiver designs rather than the transmitters themselves. | In 2010 the WPC launched **Qi Version 1.0**.
