The Basics of Wireless Charging - Why it's so awesome
If you've ever untangled a Gordian knot of wires and cords, or seen your child chewing on your laptop charger, the appeal of wireless charging is obvious.
Wireless charging was invented over 100 years ago in the late 19th century by electricity pioneer Nikola Tesla. Tesla invented magnetic resonant coupling – the ability to transmit electricity through the air by creating a magnetic field between two circuits: a transmitter and a receiver.
For about a century, this technology didn't have many practical uses, except for a few electric toothbrushes, until recently. Wireless charging has evolved to charge phones, watches, and even laptops.
How does wireless charging work?
Wireless charging isn't magic. Wireless charging works by creating a magnetic field between two circuits: a transmitter and a receiver. The transmitter (charger) uses an induction coil to create an alternating electromagnetic field, in which the receiver coil in the phone converts back into electricity to be fed into the battery. They typically have to be within close proximity of each other to work.

Which phones support it?
Almost every modern phone can use a wireless charger. Qi charging is integrated in devices by Google, BlackBerry, HTC, LG, Motorola, Nokia, and Samsung. You'll find a full and very long list of compatible devices here.
What are the advantages of wireless charging?
Charging without wires isn't only convenient; it's safer and places less strain on your devices. Wireless chargers cause little-to-no damage to your phone's charging port. Qi wireless charging pads are installed in various places around the world. Airports, restaurants, and hotels are beginning to see the value of having wireless charging pads, tables, and even night-stands equipped in their businesses!
The future of wireless charging
Now that wireless charging is becoming more popular and convenient, we're seeing it pop up everywhere we go. Lamps and tables with wireless charging capabilities are just the beginning. Imagine being to set your phone down on ANY surface to get your device to charge. You wouldn't have to ask the bartender to charge your phone or get off your couch to find your charger.
Some companies are also beginning to experiment with over-the-air wireless charging to devices. Imagine being able to lounge anywhere away from an outlet and still see your battery fill up. Wireless charging could become as nonchalant as WiFi. It could completely revolutionize the way we view power.
But until that day comes, having a wireless phone charger is a must.
