Recently got a new Android cell phone that features wireless charging. Great! It is supper nice to just rest the phone on the charger vs. having to plug in a cable all the them. I specifically sought out a charging stand that has two coils so the phone can be in either vertical or horizontal position, and was rated to work with phone protective cases. FYI not all charging stand come with AC adapters!
It worked great, until I brought into the office and plugged the USB cable into the surge protector at my desk which has a 2.1amp USB outlet. The phone would charge for 10 seconds then say: "Wireless charging has been paused". After a bunch of Googling and trouble shooting, (different USB cables, different chargers, different power sources, rebooting in safe mode, clearing app cache).
I discovered that the phone would charge without the OtterBox Commuter series protective case. I remembered that when I first used it at the house it work just fine, however I was using an OEM Samsung Fast Adaptive Charger. Hmmm....grabbed one and plugged that stand into and presto...works like it should. Now why the Samsung charger works and a normal "dumb" 2.1amp USB charger doesn't I don't know.
FWIW the Samsung Fast Adaptive Chargers list two power modes: 2amp @ 5v and 1.67amp @ 9v....interesting.
