Default [Q] Maxx + Nexus 5 Wireless charger = SadFace?

I just picked up a Nexus 5 wireless charger, intending to construct the wireless car mount discussed in the Accessories section (I can't post there yet, so I'm posting here). However I can't get the charger to work on my Maxx.

I was under the impression that the Nexus 5 wireless charger was Qi-compatible, but I don't see the logo anywhere on it. Has anyone had any luck with it, or am I just misinformed about its compatibility?

Thanks in advance!
