How to Use a Wireless Charger Wireless Charging Explained

It’s much more reliable than a regular USB cord as the magnets guide the plug into the correct position on your device every time. There’s also something to be said about it protecting the integrity of your phone’s cable port.To clarify, inserting and removing the charging cable can damage the hardware of the phone over time. This could make it difficult to take advantage of your phone’s functionality.

The most popular wireless technologies now in use rely on an electromagnetic field between a two copper coils, which greatly limits the distance between a device and a charging pad. That’s the type of charging Apple has incorporated into the iPhone 8 and the iPhone X.

Qi wireless charging relies on the close proximity of charging coils located in both your phone and the charger. Because MagSafe’s magnetic attachment holds your phone in perfect alignment with those charging coils, you’re able to get a better, faster wireless charge. One other issue is that even if you do have the right device, like the Pixel 7 with Peak Design’s Everyday Case, there’s no guarantee it will work with every MagSafe product.

The use of resonance enables high levels of power to be transmitted (up to 11kW) and high efficiency (greater than 92% end-to-end), according to WiTricity CTO Morris Kesler. WiTricity also adds capacitors to the conducting loop, which boosts the amount of energy that can be captured and used to charge a battery.

Despite its long history, however, this tech is just now becoming ubiquitous. In fact, the wireless power market is expected to exceed $40 billion by 2027, according to Allied Market Research. Sometimes you need a battery boost but don’t want to interrupt the action on your device.


There are a wide variety of wireless charging dock styles out there to suit your specific needs and preferences. You’ll even find styles to match the decor of your home or office. Right now, wireless charging with Qi is generally slower than regular charging because it loses power during the wireless transmission process. Typically, a standard charging cable will be up to 30 percent faster than a wireless dock, but that’s diminishing as the technology advances. Is it possible to demagnetize a credit card using a wireless charging pad?

An introduction to wireless charging, how it works and its applications today

Alternating current is sent to the induction coil inside the charger. The magnitude of alternating current is always fluctuating up and down, which also makes the magnetic field fluctuate in strength. Read more about Magnetic Wireless Charger here. RF charging uses a radio frequency transmitter and a receiver embedded within the device (not a coil) to pick up RF energy and convert it to power. RF provides low power at distances ranging from a few centimeters to a meter, delivering true spatial freedom. This means it works well with wearables, medical devices or other devices that need the broadest spatial freedom.
