Pi Wireless Over-the-Air Charger

The battery life of most smartphones can be frustrating. Even if you have a high-end phone that come with massive 4,200mAh batteries, you are still looking at around two days of average use. Once the device runs out of battery life, you either have to plug it in for a couple of hours or place it on a wireless charging pad, if your phone supports it.

Things could be quite different in the future. A company called Energous is developing technology to charge devices over the air. You will have place your phone within three feet of the WattUp Mid Field transmitter and it will start charging right away.

With over-the-air charging, you would never have to worry about running out of battery life again.

Imagine a future where these transmitters are a lot more powerful and can charge devices over-the-air at great distances. They could be placed across countries, just like cell phone towers today, and would constantly charge your smartphone from afar, making sure it never runs out of battery life. These charging transmitters would be so powerful, they would keep your smartphone’s battery at 100 percent all the time. You would never have to worry about battery life again and would get rid of all those charging cables for good.

The technology wouldn’t be exclusive to smartphones either. It would constantly charge all your gadgets, from Chromebooks, to Bluetooth headphones, and smartwatches. It could even charge your electric car, which is what we will probably all be driving in the future.
