I woke up this morning and saw last night forgot to put my phone on the charger. I use the Belkin 2.5 because it charges faster. It proved it this morning. Phone was at 48% when I plugged into charger at 7 this morning. It's 8:30 and is at 97%. I don't think that's a bad time frame not being "fast wireless charging". That's actually pretty close to fast wireless charging when I was using Samsung.
The larger power brick whether using from Belkin or your iPad will definitely charge your phone faster than the brick that comes with your phone.
