If you ofoften stay out of power in the most compromised situations and are tired of your constantly drained battery in your smart phone then this app is perfect for you. Nowadays we are surrounded by Wi-Fi networks. Wi-Fi networks operate by emitting electromagnetic waves. Each WI-FI access point can cover about 200 meters away. To ensure network coverage WI-FI access points emit more power than necessary. The most widespread Wi-Fi networks emit in a range between -70 and -90 dBm with a power up to 10pW. WI-FI Charger uses the WI-FI networks excess power and uses it to charge your Smartphone. WI-FI Charger does not compromise the operation of Wi-Fi networks at any time, only uses the spare power of the access points.
