Cradle for my Samsung EP-PN320 Wireless Fast Charger. This is an excellent fast charger for the iPhone 8 however you need to have the iPhone aligned properly in order for it to charge. You can find these fast chargers on Amazon, this is the 2A US version.
This is a simple design that aligns the iPhone 8 so no more fiddling with your phone. The cradle measurements are 142mm x 73mm which should be fine for slim cased iPhone's.
