Anker is $$$ but, sleek quality products.
Color: Phantom Gray
The price is steep for sure, snag one used or if listed on sale. Solid unit, functionality is on point. Keeps phone cool, charges quick, and cooling system is very quiet. Cord is braided, 5ft. The unit doesn’t have enough weight or grip to hold itself in place when removing your phone, needs kind of a peel motion or support when pulling off your phone. Otherwise, the head swivels to adjust viewing angle.

Works great with iPhone 17
Color: Phantom Gray
Excellent product. It may seem a bit pricey, but it’s definitely worth it. The magnet is strong enough to hold the phone securely, even with a lower-quality case. I’ve been using it for about six months with an iPhone 17 Pro and an Apple Watch, and it works great. The size is just right, and it operates very quietly compared to similar products. The base is sturdy enough to handle accidental bumps when placing or removing the phone, especially at night. The functionality is solid, and the different charging modes are very useful if you need faster charging. Overall, it’s worth the price, and I definitely recommend it.

A whole lotta charger for the price
Color: Phantom Gray
Let’s get this out of the way first: the Anker Prime MagSafe Charger is one of the most expensive, if not the most expensive, 3-in-1 wireless chargers out there. You can find plenty of cheaper options, but as the saying goes, you get what you pay for, and there’s a lot here that justifies the price. The standout feature is Qi 2.2 25W charging. You’ll pay extra for faster charging, but this is one of the few chargers that gives you multiple charging modes (Boost, Ice, and Sleep) depending on your needs. The Ice mode, which keeps your phone cool while charging, is a big deal for long-term battery health, especially if you tend to keep your phone for a few years. The built-in Apple Watch charger supports fast charging, too. My older Belkin 3-in-1 was fine for the first wave of Apple Watches that supported fast charging (Series 7), but slow with my Ultra 2 and 3. I have verified this one charges at 5W, which makes a noticeable difference. It also handles AirPods charging without issue, no slowdowns or inconsistency so far. You can customize settings through the touchscreen, though it’s not very responsive. I recommend downloading the Anker app, pairing it via Bluetooth, and running a firmware update. The app makes adjustments much easier than using the on-device controls. Overall, I’m not sure I’d pay full retail for it, but if you catch it on sale, grab it. It’s a premium charger that feels built to last for years.

Want to love it but for the price it could have been much better
Color: Phantom Gray
This is one of the most expensive chargers I have bought in a long time, but given it comes from Anker, a very reputable and trusted brand with top quality, I bit the bullet and had high expectations. It is a unique design whereby it uses an LCD screen to display the charging wattage in real-time for 3 devices, and also connects via bluetooth to the Anker app for customization and charging data visualization. The design is elegant (would have been even nicer to have different color options for the metal arms) and as unique as the price, while it seems to work really well with the tested Apple Watch Ultra 3 and an iPhone 17 Pro Max plus a case of Apple AirPods. The best feature of the phone charger part is peltier cooling, the latest advancement in optimized wireless charging, which uses a built-in peltier cooling system with a fan and thus prevents the phone from overheating which in turn extends battery life. So given the phone charger is 25W and to assist in the cooling, there is a built-in fan behind the phone charging puck and while not very loud it is audible at night in a very quiet room like a bedroom. If placed on an office desk I am sure you would not hear it. The unit also has a night mode accessible via a touchscreen that stops the fan completely for full silence, but also reduces the charging power and cooling to compensate. The LCD display shows real-time charging power for each device and also has a "screen saver" that shows a clock if so desired with 3 themes. Of course there is Bluetooth as well so the Anker app can be used to remotely see the status of the charger and change some settings but you have to be in Bluetooth range. I knocked off one star for the high $180 price, which I think is excessive, as well as for the fact that the Apple watch charger is limited to 5W. Given the price and that it is a brand new product, Anker should have accounted for the new Apple Watch Ultra 3 models fast charging capabilities, and reviewed Apple's tests with high-power chargers. Anker support is as always outstanding, and overall this is a very high-end and elegant looking charger, but be aware of the nuances mentioned. I am going to keep it for use in my office but not in my bedroom.
