I have this one. It's under 10$. Its slower than charging with my cable but works perfectly fine for me. Sister & mum have the same, no conplaints :)

There's a badjillion of them. Slap "Qi charger pad" into Amazon, tick "prime only plz" and you'll get dozens. I use one of these that cost me $10. It's the same damn thing over and over and over again in that design. (Welcome to china)

Non-mobile: I have this one.

^{That's why I'm here, I don't judge you. PM /u/xl0 if I'm causing any trouble. WUT?}
