With this wireless receiver, you will be able to use any Qi compatible wireless charger. Qi is the most common wireless charer available, and is supported by Nokia's wireless chargers (Fatboy and the charging plate) as well as third parties such as Tyle.
This charger doesn't work with any other charging port, which means its limited to newer Apple products, starting with the iPhone 5 (not compatible with the iPhone 4S or earlier products).
Because it adds thickness to your phone, it won't fit under hard cases. Soft cases are the only ones that allow for enough flex to fit this conductive charger.
All devices that can be charged over Micro-USB, USB-C or a Lighting Connector can be converted to charge wirelessly via a strip that you stick to the back of your device and plug into the appropriate port.
