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 is yet to become available to buy.
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.
This 10W Qi charger might be faster than the iPhone can currently handle, but that speed might come in handy for future generations or if you have other wireless charging devices.
The Zendure stands out for its affordable price and unique, super-grippy design. It features circular ribbed rubber on top, which could potentially collect grime, but keeps your phone perfectly still.
A green LED is found at the front to denote charging, but it’s not bright enough to light up a dark room and keep you awake.
This wireless charger will piwer your iPhone from a distance of 6mm, and is quick to recognise your device and begin charging.
Anker PowerWave 7.5W Pad
Anker is well known in the world of phone charging, and this is one of several examples of its Qi chargers in our round-up. It's more expensive than some of the others, and that's because it has a much better specification, and comes bundled with a Quick Charge 3.0 mains adaptor for when the iPhone's max 7.5W wireless charging is just not enough (you will need to supply your own Lightning cable for such an event, since the pad connects to the adaptor over Micro-USB).
If someone in your household is an Android phone user, it's also good to know it can ramp up the power to 10W on supported devices.
The Anker is very well designed, with a fan in its base to prevent it overheating when it's left on longer than necessary, and a small blue activity LED that is functional but won't keep you awake at night. We like the light grey non-slip surface too, so your precious iPhone won't accidentally end up on the floor.
The Anker will wirelessly charge through cases up to 5mm.
Anker PowerWave 7.5W Stand
Identical to the Anker PowerWave 7.5W Pad in all but design, this Anker PowerWave Stand costs a few pounds more but has a handy upright design that enables you to carry on using your phone as it charges.
It has all the same features as the pad listed above, including the grippy surface, activity LED, Quick Charge 3.0 mains adaptor and fans built into its base.
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.
Case-Mate Power Pad
Currently only available in the US, it's still worth an import to the UK if the design, price and functionality suits you as it does us.
You can use the pad flat on a table or in the stand to charge your iPhone X or iPhone 8, and yes, it's a fast charger thanks to the 10W output.
The stand doesn't clip into place but when lying flat the rubber surface stops your glass iPhone from sliding about. An LED shows your phone is charging, making it a decent all-round wireless charger.
Native Union DROP Wireless Charger
This smart, luxury-feeling wireless charger by Native Union is a top choice. Its subtle crosshatch design is grippy to ensure your glass iPhone doesn't slip off when charging.
It's also fast-charge compatible with a 10W output, so your iPhone X will charge that bit quicker. We also tested it with Samsung devices and it fast charges too.
It does make a slight noise while in use so it may not be best for overnight charging. It also doesn't come with a plug, just a USB-C cable, so you'll need to provide your own 10W charge plug to charge at all, let alone fast.
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.
