Is the DT-900 wireless charger compatible with the new Windows Phones, the 640 generation?

[WPCentral Question]

I'm asking because I bought some time ago the DT-900 for my lumia 920 and it was working pretty fine. Later I bought the 640 xl and it doesn't charge with my DT -900. The 640 xl has the wireless charging compatibility right?

the 640xl doesnt have native wireless charging, you can add an external micro usb charging slimline adapter etc, but the dt-900 has worked for me with the following

lumia 920, lumia 1020, lumia 1520, so any phone that is Qi basically! HTH

 

[RumoredNow]

The Qi Standard works between any compatible charger and device.

Unfortunately, the Lumia 640 XL does not have Qi charging built in. FAQ - Which features does my Lumia support? - Microsoft - USA

You could try a mod (wiring it in yourself) or an add on a Qi Adapter: qi adapter | eBay
