Is it just another gadget that’s about the novelty or is it really more convenient?
Wireless charging is said to be the next gadget to hit big. Most smartphones already have built in power transmission capabilities for wireless charging. Of course many will, and already have started celebrating the coming of the age of wireless charging, most of us are unaware of what it entails and how it works?
Not a new invention, wireless power transmission is actually qute old, discovered in the late 1800s. Nikola Tesla demonstrates inductive charging with electric lamps without wires -you may also recall this from the movie “Prestige.” The actors of the wireless realm today, include: Wireless Power Consortium (WPC) with Qi standards, the Power Matters Alliance (PMA), the Alliance for Wireless Power (A4WP), various brands from various industries, and electronic companies.
Wireless or inductive charging employs an electromagnetic field to carry energy between two items or two coils; a transmitter coil and a receiver coil. The electromagnetic field generates a voltage in the receiver, which powers your device. In other words, you merely place your device on a charging dock, and wait for it to charge. Science is magical, isn’t it?
It’s true, from Nikola Tesla to today is quite a long time to take wireless mainstream, but everything has its time. Today, almost any device can include a wireless charging capacity built-in. Our public and private spaces will soon hold wireless charging units for your convenience. It has, in fact, already started; 50 McDonald’s locations in the UK have such charging stations.
So, what are the benefits and the disadvantages?
No more tangled power cords are an obvious one, however, it is also more durable and more eco-friendly as it eliminates electronic waste. Moreover, soon, one wireless charging station may be compatible with all your devices, meaning no more confusion and inconvenience. You’ll be able to charge all your devices using any charging dock in any location, including airports, restaurants, gyms, cafes, and of course, your home. It’s truly “One for all and all for one!”
For now, the disadvantages come in with its charge speed, efficiency (60%-70% efficient) and price. However, these components will undoubtedly be corrected in the near future, as tests are already being conducted with ultra thin coils and higher frequencies to lessen transfer losses and increase charging speed.
Whether it’s the novelty, convenience, eco-friendliness, or mysticism, you can be the judge.
