I used one of these so I could see the clock on my phone at night from my bed. To do that with a cable would require I plug it into a charger and set it on a stand.. so why not just set it on the stand and go. It was very convenient and served two functions for me.

I got this Anker one for $22. I believe it's 5Watt. Should i return it and exchange it for this samsung one? Or will in not make that big of a difference?

Also, is it possible for a cheaply made wireless charger to damage your phone? I'm worried now i should just buy samsung and not some off brand
