Apple’s AirPower was supposed to be the only wireless charger you would need. One charging mat that lets you charge an iPhone (or Android), Apple Watch and AirPods. Apple decided to cancel the AirPower before it ever shipped. They sited quality/technical difficulties. I can only imagine that this was because you would have been able to put your phone, watch or AirPods anywhere on the mat. Since the Apple Watch doesn’t use a standard Qi charger I’m sure it was hard to make it work when placed anywhere on the mat.
There are lots of Qi wireless chargers on the market. Some are designed just to charge a phone while other bigger mats are designed to charge two to three devices. I originally went with the Nomad Wireless Charger as it was one of the first to have an integrated Apple Watch charger. The Nomad solution works fine, but what I didn’t like about it was that it was one configuration. You lay your phone on it either vertically or horizontally and you put your watch on the dedicated spot. If you want to charge a third device then you put the phone vertically in the middle. What I don’t like about this is that you have to put the phone on it just right (not to far forward and not too far towards the front) or it won’t be on one of the three charging coils and therefore it won’t charge. I have woke up on occasion only to realize that my phone didn’t charge because it wasn’t sitting on it just right.
SliceCharge Pro offers six high speed charging coils instead of three or four
