It’s 15.4cm (6in) high, 15.9cm (6.3in) deep and 8.5cm (3.4in) wide. In comparison, the Belkin 3-in-1 is 13.5cm wide. For an even smaller footprint, consider the OtterBox 3-in-1 Charging Station, reviewed below.

The MagSafe Duo Charger is clever, compact and incredibly expensive for what it does. It can charge a MagSafe phone (at up to 14W) and an Apple Watch at the same time, then fold into a 75-millimeter-by-80-millimeter-by-15-millimeter square. It connects via a USB-C to Lightning cable, which is included, but requires a 20W or greater USB-C charger, which isn’t. Well-heeled frequent flyers could consider it, especially if you can write it off, but business travel isn’t exactly booming again. Maybe if it were half the price! Its main advantage over the non-certified competition is its 15W charging power. It’s still half as fast as using a Lightning cable, however, and if you are going to the bother of connecting this to a USB-C charger, why not just use a Lightning (iPhone 12/13/14) or USB-C (iPhone 15) cable? You can fast-charge an iPhone to 50% battery in around 30 minutes using a cable, while it takes around 50 minutes to wirelessly charge iPhone from 0 to 50% using even 15W MagSafe.

Oh, and the iPhone 12 Mini and 13 Mini are capped at 12W charging via MagSafe, rather than 15W, for heat dissipation reasons. The Zens charger also super-convenient. Being able to fully charge four Apple devices overnight with a single charger is handy in itself, and being able to do this so easily using a compact unit is ideal. This compact 15W charger performed as well as the Logitech Powered Pad and Moshi Otto Q on our tests (though we didn’t have a 15W phone to test with). If you prefer a status indicator that turns off after a few seconds, or like the look, it’s a decent option, though the AC adapter (integrated to the barrel connector) is a bit bulky, and the faux suede top tends to look disheveled unless you brush the nap in the same direction. We prefer chargers that don’t require brushing. The Logitech Powered Pad costs less and feels more substantial, while the more expensive Moshi Otto Q also supports 15W charging but uses USB-C, so it’s more flexible, and we think it looks better. In terms of generic chargers, the fastest speed you'll get is the Qi standard of 7.5W. This isn't particularly speedy, but it'll work with any wirelessly chargeable smartphone, or other devices like wireless earbuds at slower speeds. Is 10W or 15W better for wireless charging? Made for MagSafe: Official MagSafe provides the fastest possible charge up to 15W for iPhone 12 and up;

The iPhone 8 and newer can charge via Qi at up to 7.5W, but the iPhone 12 and 13 series also support MagSafe, Apple’s proprietary magnetic wireless charging standard, at up to 15W (12W for the 12 Mini and 13 Mini). The 4-in-1 Modular charging station for iPhone with MagSafe, AirPods, Apple Watch and iPad has a carefully designed, magnetic connection that gives users the freedom to connect and create an ideal charging combination. The main station of the charging combination, connects to power via a 65W power adapter that is included in the box.

Size and shape: Since wireless chargers sit out on display, they might as well look good and not take up too much room. The base charges at 7.5W and can be used to power up AirPods or a second iPhone, and the Watch part fast charges at 5W. If you want a charger you can show off (or at least one that complements your decor), consider the Moshi Otto Q. With its heathered gray fabric top and metal-look case, it resembles Scandinavian hi-fi equipment and doesn’t look out of place on a nightstand, dresser or console table. It can deliver up to 15W to the (vanishingly few) Android phones that support it, 9W to Samsung phones and 7.5W to iPhones. The Evolved 3-in-1 Foldable Charger is a neat, portable way to charge all your Apple mobile devices—Watch, iPhone, AirPods—at the same time.
