While some Android manufacturers have included wireless charging in their devices for some time, it only hit mainstream consciousness once Apple added this feature to its latest iPhones.
It was only a matter of time before Apple integrated wireless charging into its iPhones. The iPhone 8, 8 Plus and iPhone X are compatible with the Qi (pronounced 'chee') standard also in handsets like the Samsung Galaxy S8.
While the phones won't ship with wireless chargers, the universal standard means you can buy third-party charging pads that will work perfectly.
Apple is working on its own wireless charging pad called AirPower, which will be big enough and smart enough to charge an iPhone, Apple Watch and AirPods at once. We expect it'll come at a high price, and it's not set to arrive until next year.
To begin with, Apple's iPhones are capable of 5W wireless charging, but with iOS 11.2 this will increase to 7.5W. But that's still not particularly fast, when you consider that wireless charging on Samsung phones can go up to 15W.
It's important to note that not all wireless chargers come with a wall plug, which means that even if your iPhone and the wireless charging pad supports 7.5W charging, you'll need to use a more powerful wall plug than a 5W iPhone plug.
Now that we've explained the technical stuff, let's take a look at some of the best wireless chargers for iPhone.
Belkin Boost Up Wireless Charging Pad
Belkin has been first out the door with a pad marketed for iPhone 8, 8 Plus and iPhone X, and is one of the two chargers mentioned by Apple during its keynote.
Belkin's offering is a neat white disk that has an LED to indicate when your phone is charging, and an AC adapter is included.
Mophie Wireless Charging Base
Mophie's Wireless Charging Basis was also mentioned by Apple during its iPhone launch, this time a simple black disk that is capable of charging the iPhone 8, iPhone 8 Plus and iPhone X.
The charging indicator is a small light that shines downwards onto the surface of whatever you've rested it on, which we expect could be a bit tricky to spot but at least it can't get covered up by the phone itself, unlike the Belkin charger.
It's typically ships within a week if you choose the free delivery option, though you can get it by the next day if you pay the premium.
Anker PowerPort Wireless 5 Dock
Not just a wireless charger but also an iPhone dock, Anker's PowerPort Wireless 5 Dock (£18.99 from Amazon) makes it easy to carry on using your iPhone as it charges. It has a 5W output, but Anker says it can cut 40 minutes off the charging time for an iPhone X (3.5 hours rather than 3.9 hours) over comparable wireless chargers.
It can charge through cases 5mm thick, and features a nice design with a blue circular LED at the front to let you know it's charging. Charging is possible with the iPhone in both landscape and portrait mode.
Anker PowerPort Wireless 5 Pad
If all you want is to throw your phone onto a wireless charger at any angle, this second option from Anker is for you. The iPowerPort Wireless 5 is a pound cheaper than the dock, which is nice, and it's also a bit faster too, promising to charge an iPhone X in 3.2 hours (both have 5W outputs).
The Anker has a rubberised surface that prevents your phone slipping off when it isn't in a case (though it will charge through cases up to 5mm thick), and the LED that lets you know charging is in operation is small enough that it won't distract you at night.
Anker Wireless Charging Pad
A third offering from Anker, this pad is under £20 and will do the job well. It doesn't look quite as stylish as some of the other options here, with a black, slightly squared design, but its LEDs let you check whether your iPhone is charging at a glance.
This wireless charger also comes with an 18-month warranty.
WoodPuck: Bamboo Edition Qi Wireless Charger
The WoodPuck, made by Fonesalesman, is a cheap and cheerful wireless charging made with bamboo. It comes in a lighter Cappuccino colour or darker Espresso, and is available to buy from Amazon.
There's no LED, but it does make a sound to acknowledge when your phone is charging.
Choetech Wireless Charger
Another cheap option is the Choetech Wireless Charger, which is probably the simplest of all of the chargers listed here hence its low price tag.
There's an anti-slip portion in the centre of the pad to keep your iPhone in place, and a small light at the front to indicate when it's charging.
