qi charger that reaches 40mm

[Roger Davies]

Wanting to have a setup on a boat with a wireless charger mounted under a dash. Set your phone on the right spot, it gets charged. With the wireless charger and a bluetooth radio its going to real cool.
Been looking all over the web for a charger that meets this new qi standard of 40mm charging distance. Have not had any luck yet. Has anyone come across one , or even better, had any experience with one?
Thanks!
