What it is: A company called Energous is working on wireless charging and Apple may be one of its prime customers.
One huge problem with mobile devices is that you have to charge them. Visit any airport and you’ll find people huddled around electrical outlets, charging their phones and tablets before boarding a plane. Although most mobile devices can last several hours on a single charge, running out of power is always a concern.
To charge most devices, you have to plug a cable into the device and into a power source. Cables automatically restrict your mobility, which defeats the purpose of owning a mobile device in the first place. Even though the Apple Watch doesn’t require a cable to be plugged into it, it still needs a charging cable that attaches to its back.
That’s why Energous may have the solution. This company sells a transmitter that can recharge devices up to 15 feet away. The idea is that if you have an Energous transmitter in the room, your iPhone, iPad, or Apple Watch could be charging without any wires. Now you can comfortably use your device without relying on any type of charging cables at all.
For the Apple Watch, this means people could sleep with the Apple Watch strapped to their wrist so it can monitor their health as they sleep and recharge itself at the same time. For iPhone or iPad users, this means you can walk around a room and use your iPhone or iPad without worrying about running out of power. Unlike ordinary electrical outlets that force everyone to share with cables snaking out everywhere, an Energous transmitter could send power to multiple devices without relying on multiple cables tangling everything up like strands of spaghetti.
Wireless charging is definitely the future. Charging cables are limiting and restrictive so wireless charging has a huge opportunity. The only question is how far can the Energous transmitter recharge devices? Right now it appears an Energous transmitter needs to be in the same room, but if you could put a single transmitter in a home or office and charge multiple devices from long distances away, that would solve the recharging problem in a hurry.
Such wireless power recharging is coming. It’s just a matter of waiting for it to arrive in one form or another.
