Best Prices Today: ESR CryoBoost Foldable 3-in-1 Magnetic Charging Station (25W)

$99.99

You don’t have to be an Apple fanatic to own an Apple iPhone, AirPods and Apple Watch too, but, if that’s you, you’d be crazy to ignore a 3-in-1 multi-device charger that will keep your desk free of snaking cables and three different chargers each requiring power.

We’ve reviewed the best magnetic wireless chargers for iPhone and best Apple Watch chargers, and that includes multi-device 3-in-1s and even 4-in-1 chargers. One section of that collection is for wireless chargers that can power up multiple Apple devices but also slip into your pocket or backpack for travel convenience.

The ESR CryoBoost Foldable 3-in-1 Magnetic Charging Station (25W) has a name longer than its compact body but includes the latest, fastest wireless charging technology to keep your iPhone charged to full in the shortest time.

Cool design

The black-only fold-out stand design is a familiar one, seen before on earlier chargers and similar to Ugreen’s equally speedy 25W MagFlow 3-in-1 Magnetic Wireless Charger.

ESR’s model is more plasticky, which might sound unattractive but it means that it’s lighter and therefore much more portable for travel or commuting purposes: 148g compared to 210g for the more metallic Ugreen.

At 4.3 x 2.4 x 0.63 inches (11 x 6.2 x 1.6cm) it’s easily pocketable, and a little shorter than the MagFlow.

While there are prettier (Journey SWIV) and smaller (Kuxiu X40 Turbo) 3-in-1 travel charging stations, only the 25W ESR 3-in-1 boasts a clever fan to keep your iPhone cool while it charges at top speed.

Folded shut for transit, the Qi 2.2 pad remains available for charging while covering the AirPods and Watch charging modules. Pull the pad up to create a stable stand, as well as opening up the other two wireless charging points.

It’s a neat design that also exposes the CryoBoost fan that helps chill the phone as it charges. 25W is a lot of power and that heat can trip the heated iPhone into a slower charging mode. The fan is whisper-quiet and should ensure that the full 25W is employed throughout the session.

Performance

ESR claims that the CryoBoost active cooling can reduce heat by up to 10.8°F and therefore maintain the 25W power before the iPhone overheats and turns off charging until it’s feeling better again.

It’s a technology that ESR introduced for even some of its 15W wireless chargers, and it certainly makes a difference in terms of performance.

While it can take a 15W charger around 45 minutes to charge an iPhone from 0 to 50%, a 25W charger can do the same in around 30 minutes. If you’re just charging overnight that saved 15 minutes won’t mean much, but if you have little time to get powered up it might make all the difference.

At 5W the Apple Watch is also fast-charged, and the AirPods couldn’t take in any more power than its Qi pad offers.

Note that only the iPhone 16 and 17 series benefit from that full 25W. Earlier iPhones (12-15) are pegged back at 15W. That’s an Apple limitation, and nothing to do with ESR or other third party charger makers.

The ESR CryoBoost Foldable 3-in-1 Magnetic Charging Station (25W) costs $119.99 (although was on sale for $99.99 at the time of writing), and is currently available only in the U.S. Customers who want something similar should look to Ugreen’s folding MagFlow 3-in-1. Or they can go for ESR’s 15W Foldable 3-in-1 Travel Charger that features a detachable Watch charger.

Included in the box is a one-port 50W power adapter and 5-foot (1.5m) right-angled USB-C cable.
