What is wireless charging?
Wireless charging is a convenient way to charge your devices without using cables. Simply place your wireless charging compatible phone onto a charging pad and your device will automatically start charging. Lead by two industry standards, the Wireless Power Consortium and the AirFuel Alliance.
What is Qi?
Qi pronounced “Chee” is the name of the wireless inductive charging standard from the Wireless Charging Consortium. It is the most widely supported standard in the market and supported by brands such as Samsung and Apple.
How does it work?
Qi uses inductive charging whilst Air fuel uses resonance based technologies. Inductive and resonance based technologies produce quite different results from an end user perspective, despite being based on the same engineering principle that coils of wire can be used to transmit power over the air. Power is transferred from a transmitting coil in the charging pad to a receiver in your device.
Is wireless charging faster or slower than charging by cable?
Generally speaking, wireless charging (5 watts) is 50% slower than charging by cable. With 9 watt fast wireless charging, that reduces to 25% slower and with 15 Watt super-fast wireless charging the times are comparable to Cable Charging. Wireless Fast Charging 9watt or 15watt will require a Fast Charging enabled phone. Check with your supplier for compatability.
What devices are currently supported?
Qi now the dominant force in wireless charging supports a range of phones with all new Samsung and the new iPhone 8, 8 Plus and X being supported. If your phone does not have a receiver built in you can always purchase a receiver to plug into the USB-C, Lightening or Micro USB slot on your phone. They can be easily purchased online.

How long does Qi charging take to charge my device?
If your phone charges in 1 hour, then your standard wireless pad will charge your phone in approximately 2-2.5 hours. You can say on average that the standard 5W (1Amp) Qi charging pad will charge about a third to half as fast as a standard charging cable. There are cables that are Fast Charging, so they will charge up to 6 times faster than a standard Qi Wireless charging pad. Fast Charging pads are also available. These will double or triple the speed of the wireless charging.
Do I still need an AC adaptor? Will my old one work?
No you don’t need an AC power adapter. But you will need a USB Port. This is where you plug in your USB charging cable that connects to the Qi charging pad. If you don’t have a spare USB port, most wall power adapters that come with your phone have a USB port. You can use that as your USB port if you wish.
Is it safe? Can I leave the phone on there?
Qi charging is actually very safe to use. The electromagnetic field generated by the transmitters are very small and weak in power, only operating over short distances. Inductive charging has been used in many applications, such as your electric toothbrush, medical devices and more.
Where can I use a Qi charging product?
You can use your Qi charging pad wherever you have access to a USB A port. Places such as your car, home or office via your pc or laptop. You could even connect it to a standard power bank. Or you could find a Qi wireless charging power bank with a Qi transmitter built in. Then you can wirelessly charge your phone anywhere.
What’s the difference between licensed and not licensed?
There are various options available for wireless charging. Some are certified by the Qi Wireless Consortium, the governing body for Qi charging. Look for the Qi logo to see if your model is certified. Whilst models without the Qi logo will work, those with the Qi logo have been tested and approved by the consortium.
Does the device need to touch the pad? Do I need to remove my phone case?
Your phone must be within 3mm distance of the charging pad to charge successfully. Some phone cases can be quite thick and obstruct charging however most cases will not affect the capacity to charge your phone.
What about Apple Watch and Apple Airpods?
New generation Apple Watches 3.0 and Apple Airpods support wireless charging however Apple has decided that they should only be compatible with the Apple “Air Power” charging standard. Whilst the technology is the same as Qi, Apple has decided to create their own charging standard for these two products.
