Dailysteals has the Nokia wireless charging plate for $25 shipped, both black and white colors are available. The model number is DT-900, the description on dailysteals does say it works on Nexus 4 but I have had issues on all my Nexus 4′s with the charging plate. I would suggest you do not buy this if you are looking for a wireless charger for your Nexus 4.
The plate does work perfectly with my HTC Droid DNA and Lumia 920. Click here to buy one.
