Default Searching for dual qi wireless charging pad

First I thought to buy the Google one, but it just to small, and I need 2, for nexus 5 & 7, then I thought, why not to kill 2 rabbits, with 1 bullet, and buy a dual charger, the ZENS looks good, and big, so tablet not look out of place, any other recommendations?
