20W USB-C Power Adapter

I purchased the Apple 20W USB-C Power Adapter to fast charge my iPhone, and it has performed exactly as expected. The charging speed is noticeably faster than older 5W adapters, allowing my phone to reach a useful battery level in a much shorter time. The adapter is compact, lightweight, and feels very well built, as you would expect from an Apple product. It fits securely into the socket, doesn't get excessively warm during charging, and has been reliable with daily use. I also like its small size, which makes it easy to carry when travelling or keep in a bag without taking up much space. I've used it with both my iPhone and other USB-C compatible devices, and it delivers consistent, dependable performance every time. When paired with a good-quality USB-C to Lightning or USB-C cable, it provides efficient and stable fast charging. Although it's a little more expensive than some third-party chargers, the build quality, reliability, and peace of mind make it worth the investment. Overall, this is an excellent charger that delivers fast, safe, and reliable performance, and I would highly recommend it to anyone looking for a genuine Apple USB-C power adapter.

Excellent Apple quality. Doesn’t get too hot which is a good sign. Charges fast and can be used with any usb c cable. Very portable with folding pins

The Apple 20W USB-C Power Adapter is one of those deceptively simple products that, while small in size and relatively inexpensive, ends up being a core component of any Apple user’s charging routine. In my case, I've used this specific model with an Apple Watch SE and an iPhone X (iPhone 10) over the course of several months, both at home and while travelling. This review outlines the practical performance of the adapter across daily use, examining its compatibility, reliability, build quality, voltage performance, and overall value. Let’s begin with the basics—materials and build. Apple has a longstanding reputation for sleek, clean, and durable design, and this power adapter follows that ethos. Its body is made of high-quality, glossy white polycarbonate, with a solid weight that gives a reassuring sense of quality without being bulky. The USB-C port is firmly mounted with no wobble, even after repeated use, and the prongs on the UK version are sturdy and lock into sockets firmly. There’s nothing that feels cheap or fragile here—this is quintessential Apple minimalism with performance to match. What sets this 20W adapter apart from standard chargers is its power delivery. This isn’t your average wall plug; it supports USB Power Delivery (USB-PD), enabling it to fast-charge a variety of compatible devices. With the iPhone X, for instance, I’ve been able to go from 0 to 50% in just about 30 minutes using an Apple USB-C to Lightning cable. The adapter intelligently negotiates voltage with the connected device—5V/3A for standard charging and 9V/2.2A for fast charging. These figures are well within USB-PD specs and result in highly efficient power transfer. Using the same setup with the Apple Watch SE, charging is equally dependable. The watch doesn’t draw nearly as much power as a phone, of course, but using Apple’s magnetic charging puck plugged into the 20W adapter results in noticeably faster top-ups compared to using older 5W bricks or USB-A to USB-C converters. If you’re like me and charge your Apple Watch during a short morning routine, the 20W adapter makes a real difference—it gets you enough charge for the entire day in under 30 minutes. Cable quality is a huge factor in real-world use, and not all USB-C to Lightning or USB-C to USB-C cables perform equally. In my testing, official Apple cables predictably perform best, maintaining peak voltage throughput without any heating issues. I’ve also used Anker, UGREEN, and Aukey cables—all reputable brands—and while most worked fine, some non-certified cables exhibited minor inconsistencies in charge speed and thermal output. When paired with quality cables, however, the 20W adapter shines. The charging speed remains consistent, even with older devices, and I’ve experienced no overheating or disconnections. Beyond Apple-specific devices, I tested this charger with a range of USB-C gadgets including a Samsung Galaxy Tab A, a Nintendo Switch, and a Google Pixel 4. In every case, the charger performed to expected standards, although fast charging features specific to non-Apple devices weren’t always fully supported. That’s not a flaw—just the reality of differing fast charge protocols between brands (such as Quick Charge vs USB-PD). For Apple gear, the integration is flawless. Where this adapter really earns its value is in its portability and versatility. I’ve used it while travelling in the UK and EU with a travel plug adapter, and it never overheated or faltered. It’s compact enough to tuck into a tech pouch or even your jeans pocket in a pinch, which makes it ideal for minimalist travellers. With only one USB-C port, some might wish for dual output, but I’d argue the dedicated performance of a single port is part of its strength. You get full 20W delivery without compromise. In a reliability test over four months, using the adapter daily for phones, tablets, and wearables, I’ve experienced zero failures, dropouts, or overheating. Unlike cheaper third-party chargers, the Apple 20W USB-C Adapter doesn’t emit coil whine, it doesn’t hum under load, and it maintains safe temperatures even when charging multiple devices sequentially. I’ve left it plugged in for days at a time, and it remains cool to the touch—a reassuring sign of energy efficiency and quality circuitry. n each use case, the adapter performed smoothly, with voltage stability and minimal power leakage even under varied load. Where the Apple 20W adapter might fall short for some users is in its single-port design and premium price. At £19, it’s considerably more expensive than similarly specced third-party USB-C PD chargers. Brands like Anker and Spigen offer dual-port 20–30W chargers for similar prices. However, none of those competitors offer quite the same level of integration with Apple’s fast charge protocols or the same aesthetic coherence—especially if you value an all-Apple desk setup. It’s also worth mentioning that this charger is an ideal companion for MagSafe. I tested it with the Apple MagSafe Charger, and the results were as expected: fast, stable charging with excellent thermal performance. Some off-brand chargers I tested with MagSafe would reduce current after a few minutes to manage heat, but this 20W Apple unit kept up consistent output without thermal throttling. On the safety front, the Apple 20W USB-C Power Adapter is certified to comply with global electrical standards and features internal safeguards against overcurrent, overheating, and short circuits. This is particularly valuable when charging high-draw devices like the iPad Pro or charging overnight. For those managing multiple Apple devices, owning more than one of these adapters makes sense. I eventually bought a second one for the kitchen, where it lives semi-permanently. Apple’s minimalist packaging is also worth noting—it ships in a tiny box with no cable included, but the lack of plastic wrapping and compact form is a welcome change from previous bulky chargers. It is a deceptively powerful, rock-solid piece of kit that delivers consistent, safe, and efficient power across Apple’s entire ecosystem. While more expensive than generic chargers, its real-world performance, reliability, and long-term compatibility easily justify the cost. Whether you're charging an Apple Watch SE, an older iPhone, a brand-new iPad, or just want a dependable travel charger, this adapter excels. If you’ve invested in Apple hardware, this is the charger that makes everything else just work. Highly recommended.

Brilliant 20w usb c charger made by Apple. I use it together with my Apple Watch lead to charge an Apple Watch Ultra 3 which it does very quickly. Well worth the money wouldn’t buy anything else. Will work with any usb c lead. Great quality as expected. The pins fold in and out which makes it great for travelling with.

I purchased this charger as recommended by Apple with a new MacBook neo. It does the job but I do wonder whether other cheaper 20w chargers would be adequate.

I use a iPhone 13, but originally got this for the iPad. This is absolutely amazing, and would definitely recommend to buy, as it can easily charge around 20-30% in about 10-15 minutes, it is absolutely incredible. Might be a little longer for the 17 pro, but I’d imagine would be roughly similar. The size is amazing, if you’ve had the xs max or xr? Very, very similar, and looks/and feels fantastic. Durability, it feels premium, feels strong & the sticks to put into the socket feel strong

Great plug. Good value. No cable included. Charges well

The power adapter are working perfectly well, it charges my iPhone and the battery last longer than before. The money is quite expensive but it is doing the job.

Exactly what I needed

Works well and as intended, it feels solid like it’s well made, and of course with every other Apple product it’s overpriced for what it is.

I bought it a couple of weeks ago and the adapter has stopped working, just buy it on the apple website. This is my second time getting scammed when buying an adapter.
