Someone on these forums mentioned the Zens charger over at wpcentral and that there was a discount when you use "holiday12". The store is for windows phones (specifically the Lumia 920), but since it is Qi, it of course should work the same. I emailed Zens and asked about the Nexus 4. They responded to me in less than 4 minutes confirming it works with it perfectly. With the great customer service and quick response, I bought 2 for the house.
This was their response:
Thank you for your email and interest in our products. The ZENS Single Charger works perfectly with the Nexus 4 as they are both Qi compatible, no need for a extra sleeve.
They are $48.95 each and you get free shipping over $50. I ordered 2 and with the "holiday12" coupon code, it brought my total to only $83.22.
This charger looks very stylish and does not slant like the Energizer. Our phones are so slick and I don't like having to put something down on the charger just to make it work (or having to rip out a speaker).
