how does wireless charging work

Wireless charging is definitely one of those new technologies that seems to defy our intuition. By now wireless functionality is something we've come to expect as a standard function in everything from our internet connections to game controllers, but using it to power our gadgets? Pure science-fiction, surely? Well, it's actually one of the biggest emerging technologies on the market, and in this entry of the Desktop Innovations blog, we're going to explain how wireless charging works, and highlight some of the handiest products that make the most of it.

The Science of Wireless Charging

Also known by it's more technical name, 'Inductive charging' delivers energy from one object to another through the use of electromagnetic fields. The basic principle behind the technology is this: your charge-able device contains a loop of coiled wires around a bar magnet - a setup known as an inductor. The charger itself also has an induction coil, which creates an alternating electromagnetic field from within the actual charging base station. Placing the two induction coils in close proximity  to each other causes them combine to form an electrical transformer; and allows the charge-able device to take the power from the electromagnetic field and convert it into an electrical current.

Since the strength of this electromagnetic field drops with distance, the popular wireless charging devices right now won't let you power your phone from across the room, and they won't charge as quickly as a traditional charging station. However, this technology has several advantages: the connection isn't exposed to water or other liquids, there isn't as much wear and tear as you constantly pull the plug in an out and, in the case of medical implants, they allow for safe charging through the skin without the need to insert any wires.

Interestingly, this technology has been bandied about for more than 100 years. The physicist and inventor Nikola Tesla first concluded that you could transfer power from one object to another via this method. He actually demonstrated the use of resonant inductive coupling in a public experiment though he probably exaggerated the technology's long-distance potential (particularly with his 'World Wireless System', which aimed to transmit electrical energy without wires on a global scale!).

Only in recent years have we been able to produce wires and electronics small enough to produce a significant and convenient amount of charge. As a result, the possibilities of the technology is starting to bloom, with wireless charged buses currently being trialed in everywhere from South Korea to Milton Keynes, and  with various companies such as IKEA starting to roll out new furniture ranges that include wireless charging stations.

Wireless Charging on Desktop Innovations

The most popular use of wireless charging, without a doubt, is in the mobile phone industry. Everyone from Apple to Nokia are rolling out phones that can be powered up without the use of a single cable, and in this regard we see no better route to than the Aircharge Ergo Qi Wireless Surface Charger. Designed to be installed on any surface, and to become a convenient, routine part of your day to day life, this charger works on any device with built-in Qi technology.

Even if you're using an older phone than the current generation, Aircharge have introduced multiple peripherals to bring you and your phone up to speed. For the iPhone 5, you can buy a separate Charger Adaptor Case that snaps on comfortably to the back of the mobile, and if you own any younger iPhones, or those of a different brand, the Aircharge Adaptor features a mini-USB, Lightning connector and a standard Apple 30-pin connector to help meet your mobile halfway.

Lastly, for those who want their entire interior setup to sit at the edge of cutting edge convenience, our Large Dual Monitor Stand & Desk Tidy features its own integrated Qi-enabled wireless phone charging pad, which allows you to make wireless charging an integral part of your home design. Just call us for a price!
