When it comes to travel chargers that charge all of your gear (sans a laptop), I’ve tried a ton over the years, and most have some kind of downside with either size or power. The ESR CryoBoost Foldable 3-in-1 Magnetic Charging Station might finally be the one that solves all of my charging annoyances without any real drawbacks that I can see. It’s compact enough to toss in a crossbody, delivers 25W Qi2.2 fast charging with active cooling, and charges your iPhone, Apple Watch, and AirPods at the same time. If you travel often or just want to simplify your daily charging setup, this might be one of the top 3-in-1 chargers on the market.

The big win here is the combination of everything you need right in the box. ESR includes a really thick USB-C cable and a 50-watt power adapter. The packaging makes it clear that you’ll want to use the included adapter for full performance. Overall, it’s a solid setup that works perfectly out of the box.
Foldable design
The foldable design of the ESR CryoBoost 3-in-1 Charger gives it a ton of flexibility. You can keep it folded and use it as a compact stand for your iPhone on a nightstand or desk, or unfold it to charge your AirPods and Apple Watch all at the same time. I suspect this is why ESR recommends using the included adapter. The hinge feels strong and locks into place nicely, so you can adjust it depending on where you are at (a hotel desk, airplane tray, or kitchen counters). It’s a nice design that fits multiple roles without taking up much space. It’s about as thick as some MagSafe batteries I own, which makes it an easy travel companion.
Active cooling and fast charging
The ESR CryoBoost 3-in-1 Charger is built around Qi2.2 technology, which pushes MagSafe charging up to 25 watts. That means you can take a supported iPhone (iPhone 16 and 17) from zero to around 60% in about half an hour. Wireless chargers can heat up your iPhone over time, which can slow down charging and affect long-term battery health. ESR aims solves that problem with an internal fan that kepe your iPhone cool while it charges. In testing, ESR says it keeps the phone up to 10 degrees cooler than chargers without fans, and that makes a difference in how quickly it tops off your battery. I don’t have lab equipment to measure it, but I’ve dealt with my fair share overheating from MagSafe for years, so any cooling is a win in my book.
The Apple Watch charger on the back is also worth mentioning. It’s MFW-certified, meaning Apple officially approves it for fast and safe charging. You can expect an Apple Watch Series 10 to charge from 0 to 80% in about 30 minutes. Since the charger is built right into the stand, there’s no extra cable to pack when you travel.
Wrap up on the ESR CryoBoost 3-in-1
The ESR CryoBoost Foldable 3-in-1 Magnetic Charging Station is one of the best travel chargers I’ve picked up. It hits an awesome balance between compact size and fast charging power. The active cooling means you actually get the full benefit of 25-watt Qi 2.2 charging without your iPhone getting overheated, and the ability to charge your iPhone, Apple Watch, and AirPods from one device makes it an easy thing to keep in your travel bag.
I also really appreciate that ESR includes everything in the box: the thick USB-C cable and 50-watt adapter make it ready to go without needing to bring your own cable or adaptor. Whether it’s your daily charging or in a hotel room, this is a thin and flexible charging setup that brings both speed and active cooling.
You can buy the ESR CryoBoost Foldable 3-in-1 Magnetic Charging Station from Amazon.
