Benefits of Wireless Charging 

Wireless charging is all about convenience. For example, with the right placement of wireless chargers, you could set your enabled device down at night before bed, wake up to a full charge, top-off in the car on your way to the office, and continue to power up at your workstation. An impromptu, late afternoon stop at your local coffee shop or fast-food establishment may also offer wireless charging as you sit and wait for your order. One could navigate their entire day without ever having to plug in to charge. Sounds lovely, doesn’t it? You sacrifice some speed and efficiency by avoiding the plug, but the idea is that charging your device becomes second nature as you navigate through daily activities. Aided by strategic placement of wireless charging technology, your device essentially charges while resting wherever you would normally place it when not in use. But how exactly does wireless charging work?

How Wireless Chargers Work

First, your device must be wireless charging compatible. Qi-enabled smartphones are one of today’s most common type of wireless devices. Then, you need a compatible charger which is also Qi-certified or certified by another wireless technology manufacturer. Simply position your device on the wireless charger, as instructed, and bam! You’re wirelessly charging. Wireless chargers emit an alternating magnetic field via an internal transmitter coil, which in turn induces an alternating voltage (or current) in the receiver coil, located inside your device. This transferred energy is used to charge up your device.

Have a case on your device? Not to worry. Nimble wireless chargers will still push power through cases up to 3mm thick.

Keep in mind, you’ll need at least a single cable, which runs from the wall to the charger itself. However, once the pad is connected to power, you’ll never have to fuss with cables or wires when looking to start charging your device. An indicator light on the charger lets you know when your device is receiving power and is required to flash as a warning if there is a foreign object detected, interference, or the device is not aligned properly.
