Initially I bought a GMYLE Qi receiver unit which slips between the iPhone body and any (reasonably thin) case. The receiver has a lightning connector which simply plugs in and out of the lightning socket on the phone. I paired this up with a GMYLE Mini Qi charging pad. To start charging it's simply a matter of placing the phone onto the pad until a contact is made. I was surprised how quickly the phone charged,
On the downside, it was getting the phone in the right position to start the induction process - not a real problem and one which becomes easier after a few days - but it can be a bit hit and miss. Also, the process does appear to generate more heat than using a normal charging cable plugged into a USB port.
Once I was happy with the proof of concept I decided to splash out a little bit extra and buy a proper charging stand and charging case. I went for the portable (collapsible) T-310 Foldable stand from DLAND and the KD iPhone 6 Wireless Charging case. This combination works so well that I bought a second stand to keep in the office. And a few days ago, I purchased a Moxia Energizer QI Enabled Induction case for my old iPhone 4. This works equally well with the existing kit.
There are rumours going around already that the iPhone 7 will have true wireless charging capability, but I'm afraid I have my doubts right now. But there is no doubt that not plugging cables in and out of the phone is preferable to the alternative - but it really is no more than a convenience at present. True wireless charging - now that will be a game changer!
