Has anyone concluded whether or not the 7.5w QI wireless charging for the new iPhones only works with certified Belkin and Mophie chargers, or with any brand charger capable of delivering that much? From what i've managed to dig up via google, a real conclusion hasn't been reached yet. I am getting my brand new 8 plus in the mail tomorrow and would like to get a wireless charger for it. Would love it if anyone could clear up this situation for me. Thanks!
