A 20W charger shouldn’t need a long review, and this one barely does. Apple designs iPhone charging around this brick, so it delivers a clean 20W, stays cool and is small enough that it won’t block the other socket on a wall plate.
You get one port, and you don’t get a cable.

One-sentence verdict: Buy it if you want a reliable, genuine 20W USB-C brick for an iPhone, AirPods or a MagSafe puck that you’ll never have to think about again; skip it if you need to charge a laptop or two devices at once, or you want a cable in the box.
One USB-C port, 20W, no cable — the brick most iPhones are designed around.

This is a small white cube with one USB-C port and fixed prongs. Honestly, the only design question that matters with a charger like this is whether it’s small enough to stay out of the way of the second outlet, and it is. It’s well built, too, and it avoids the cheap-brick habit of running hot.
Plug it into the wall, plug in a USB-C cable, charge your phone. That’s it.
It delivers a steady 20W over USB Power Delivery, which takes a current iPhone to about half full in roughly 30 minutes, and it’s also what unlocks the full 15W on Apple’s own MagSafe charger. It stays cool while it does all this.
Charging two things at once is the one thing it can’t do. With a single port, there’s simply no multi-device story to tell.

The vast majority of these last for years. A small number of owners do report early failures, but against more than 13,000 ratings that’s a low rate. If yours is one of them, Apple’s one-year limited warranty covers a replacement.
At $14.99, the genuine Apple adapter costs about the same as a good third-party brick, and less than it used to.
For a charger that only ever powers one iPhone, we struggle to think of a good reason to buy something else. You get predictable behaviour and a warranty for the same money as a no-name brick. If you want to charge two devices, or a laptop, buy a multi-port GaN charger instead. On sale, buy it without a second thought.

|---|---|---|---|---|
| Apple 20W USB-C Power Adapter (this charger) | A guaranteed single-port iPhone brick | Genuine Apple, runs cool, warranty, $14.99 | One port, no cable | $14.99 |

Need to charge more than one device from the same outlet? A multi-port GaN charger is the better buy. For a single iPhone, though, this is the default, and shopping around won’t get you much.
This is the charger your iPhone was designed for, and it does the job without any drama: a clean 20W, a body small enough to leave the second outlet free, cool running under load and a warranty if anything goes wrong. A 4.8-star rating from more than 13,000 Amazon ratings is about as strong a record as a charger gets.
Its limits are just what it is. There’s one port, there’s no cable, and it doesn’t have the power for a laptop or a full-speed iPad Pro. For charging a single iPhone, AirPods or a MagSafe puck, though, there’s no real reason to buy anything else.

Figures marked “Apple” are the manufacturer’s published claims. “N/A” means Apple does not list the value.
No, just the adapter. You’ll need your own USB-C to USB-C or USB-C to Lightning cable.
A current iPhone gets to roughly 50% in 30 minutes, and the adapter also enables 15W charging on Apple’s MagSafe Charger.
No. It has one USB-C port, so for two devices you’ll want a multi-port charger.
No. 20W is enough for phones and MagSafe pucks, but not for an iPad Pro at full speed or any laptop.
A good USB-PD 20W brick works fine, but the genuine Apple one costs about the same and comes with a warranty and predictable behaviour.
For a single iPhone, yes. This is the default choice, and there’s little reason to look elsewhere.
Yes, but it isn't the fastest option. Apple quotes about 50% in 30 minutes with a 20W adapter. The iPhone 17 and 17 Pro can reach 50% in about 20 minutes with a 40W or higher USB-C adapter, so if fast top-ups matter, a higher-wattage brick is worth it.
