Wireless Charger

Below are our wireless charging pads. Forget the hassle of plugging your phone into a charger. Don't worry about messy cables on your table or desk. Use wireless charging. There are many phones and devices that have the ability to be charged wirelessly.

The Wireless Charging Mat provides convenient charging without the mess of tangled charging cables. All you need to do is plug the Qi Wireless Charging Pad into a USB power source and place your compatible device on it for charging.

You place your phone on the wireless charging mat or wireless charging pad and your handset charges wirelessly, without you needing top plug in it to the charger.

Qi is one of the most commonly used standard for wireless charging in the current market. Qi is Chinese and is pronounced 'Chi'. The principle behind Qi is to allow Qi wireless charging enabled devices to work with all Qi chargers. There is no need for separate chargers, cables, adapters when traveling.

Wireless Charging Pads

Wireless charging pads are a technology that helps to make our lives easier - negating the need to plug your phone or tablet into your mains power to charge it up. The pads themselves, however, still need to be plugged into a mains power point somewhere, but you can, with some charging pads, keep these pesky cords out of sight and keep your space clean.

They are handy both for home and in the workplace, and ensure that you're never searching for a charging cord again.

How do wireless charging pads work?

Wireless charging is possible via the means of electromagnetic induction, wherein a magnetic field is created between the charging pad and your device which energy can flow through. This is what's known as inductive charging. This field isn't actually created by the pad and device, it's by conductors hidden within them both.

Within the charging pad there is an induction transmitter coil, and another, secondary receiver coil within the device to be charged.

Pure inductive charging

A charge is converted from the mains into an alternating current (AC), which then resonates outwards by the transmitter coil in all directions, creating an alternating magnetic field. If it hits the secondary coil, this secondary coil will, in reaction, induce an AC current. This current going between the transmitter and receiver coils may then be converted into DC current within the receiver field to charge the device battery. In fact, it was Nikola Tesla himself that laid down these basic principles of electromagnetic transfer.

This is the principle of pure inductive power transfer. However, in practice, pure inductive transfer has some very specific needs to be met for the power transfer to be truly effective. These are:

In practice, the effectiveness of pure inductive transfer is only about 30-60%.

Wireless charging pads - Resonant vs. inductive

Resonant wireless charging is a similar technology to inductive wireless charging. In fact, inductive wireless charging actually is resonant wireless charging - by the way that it works, with the transmitter coil inducing resonance in the receiver coil. However, in resonant charging, both coils are already tuned to resonate at the same frequency, rather than this being induced by being within near distance of the transmitter coil.

Because the two are resonating at the same frequency, this pulls them both into a stronger 'tunnel', rather than the transmitter sending out signals in all directions. This means that charging is more effective - devices can be further away.

Through this process, there is only the need for the small field - the coils don't need to be touching, and there can be space or other surfaces between the two objects, so long as the surface isn't metal - or it will interrupt the field.

How do multi-device wireless charging pads work?

Multi-device charging pads have multiple transmitter coils lurking beneath the surface, allowing you to pair multiple devices with the charging pad.

Qi standards

If you have a wireless charging pad for a mobile device, chances are that it is built to the Qi standard. Qi is the choice of wireless What exactly is that, though? Well, it is a standard that was introduced by the Wireless Power Consortium and both pure inductive as well as resonant charging in the current standard. The Qi standard aims to be as useful as possible for the largest range of devices on the market.

Through pure inductive charging, the Qi standard can be adopted in charging mats where the distance between coils (and respective casings) is up to 7mm, or 0.7cm. Through resonant charging, the standard can be adopted to stretch this distance to 45mm, or 4.5cm. Any non-metal surfaces can sit between the transmitter coil and the receiver coil without interrupting the electromagnetic field. Metal surfaces will disturb the field, making charging unpredictable. However, this means that you can install a charging pad below the surface of a desktop, for example.

These standards have been adopted by a large number of device manufacturers, including Apple, Sony, and Samsung. More specific models can be found detailed later in this article.

PMA standards

PMA is the current alternative to Qi charging, and is supported by a smaller number of devices. It presents a similar way to do wireless charging. Some devices, such as the Samsung Galaxy S8, support both Qi and PMA standards, which means that you can charge them on pretty much any wireless charging pad released after the phone was released.

Which handsets can use wireless charging pads?

Handsets that can use wireless charging are bound by whichever standard they've adopted - although typically this is Qi charging. Here we list all the mobile phones that currently can use Qi charge mats. Note that some of these models were built to previous Qi standards, rather than the most recent specification.

Even if your handset doesn't appear on this list, you may be able to purchase a cover that includes a Qi wireless charging receiver to fit over the top of your phone which will allow wireless charging.
