Anyone who uses a mobile phone, media player, or other similar things knows nothing is more frustrating than needing to use a gadget whose battery is going dead at the most inopportune time. Well, some makers of electronic accessories are perfectly aware of this problem; for that reason, nowadays there are many available devices designed to charge gadgets by using different methods… and sometimes some very unconventional methods.
One of those devices is the RCA Airnergy. According to the maker (which by now has nothing to do with the former RCA Corporation), the RCA Airnergy is able to transform WiFi signals into electricity that is used to charge its internal battery, and this in turn can be used to charge any gadget of an user. Pretty ingenious, heh? Well, let’s see.
The fact of charging a gadget by using an internal battery is not a big deal and, in fact, there are a wide variety of products to do that. There is no mystery. However, the previous process of transforming WiFi signals into the power source of a device might sound less than fully convincing for some people.
