Need wireless charging receiver?

I got new Iphone5 and my family wants to go to some camp house and charging my iphone can be difficult since electricity goes off randomly. I need a wireless charging receiver for my Iphone5.

Charging would be more efficient with a regular charger. Besides, even if there was a wireless charger, it would rely on nearby wireless to get any signal - and if power goes out for your charger, it will also go out for the wireless signal. Any wireless charger has to be close to the wireless source. Often, the wireless charging system also includes a transmitter, so it may not even be the "wireless" we think it is (not 2.4Ghz). If there are two parts to it, you still need "power" to make it all work.

Charging over wireless, while technically possible, is such a low energy producer, that it would take days to fully charge a battery. You are better off using a regular charger, even for just 1 hour a day if possible - much more charge that way.

I had the same problem and my friend suggested me to buy QI wireless charging case for iphone5 and I did. It was great. It was my life saver. QI wireless charging case for iphone5/5s comes in two colors: black and white. It is reliable and 100% compatible with Iphone5/5s. Its charging current is 800mA and charging rate is more than 72%. I take it everywhere. It is really light only 30g and fits everywhere. It is really good. You should buy it.

There's no such thing.

If the electricity goes off randomly, just charge it when the electrics is on.
