"Offered in a variety of colours, this functional shell (cover) contains a ""Qi"" compatible wireless charging coil, enabling a device to charge without wires and without changing the original design of the product.Wire coils found inside compatible products receive power when they come near charging stations, recharging batteries with efficiency rates rivaling the average wired charger (in fact, it's over 80% as efficient). Even though the coils and station never actually come into physical contact (as the back cover remains between them), energy flows and recharging happens when the two are in close proximity (typical range of 3mm). This technology is called ""inductive"" or ""closely coupled"" charging. All of our wireless charging products also feature the latest advances in Foreign Object Detection, which means they don't become active if someone accidentally drops keys, paper clips or any object that's not specifically designed to be charged wirelessly.
