If you are feeling that you are not fully happy with your Galaxy S4, maybe it has a problem, or maybe you just need the device’s official wireless charging kit! It’s available in the US now from Samsung’s accessory store.
You will need to buy both a charging cover and the charging pad, which cost $39.99 and $49.99 respectively. Qi wireless charging standard is being used here, so you can ignore the pad if you already have a Qi charger.
But just in case you haven’t heard, there is also the WiQiQi S4 wireless receiver and charger set out there. With this charger, there won’t be any need for replacing the back cover. And it seems that they are just asking $49.99 for it at the moment. But you can forget about it if you are someone who likes all things official.
So have you placed an order?[Source]
