I spent some time traveling in late July and put the LISEN CardMag MagSafe battery pack through a tough test with heavy usage, high temps, and everything in between. I was in the northeast and on the go constantly. I’m also running the iOS 26 beta, so my iPhone battery isn’t exactly thriving right now. I had Apple Maps going constantly as we navigated cities, used the subway, and more.

Why the LISEN CardMag stands out from other MagSafe batteries A few things make the CardMag my go-to battery right now, and why I loved it on a recent vacation. First is the built-in USB-C cable. I’ve run into plenty of situations where it’s just too hot outside for MagSafe charging to work well. This is especially true if you are outside walking around, etc. Your iPhone gets hot, charging slows down, and sometimes it stops altogether until the iPhone cools down. Having a cable built in means I can switch to wired charging until that happens. Second is the Apple Watch charger. It’s built right in, so you won’t need to carry a separate puck. You could use it to charge your Apple Watch at night or top off after a long workout, etc. The third thing I love about the LISEN CardMag is the digital display. I much prefer it over the batteries with the little dots. With the CardMag, I always know exactly how much charge is left and whether it’s actively charging. It’s a small feature, but super helpful when you’re trying to manage power on a long day. Key features The LISEN CardMag supports iPhone MagSafe charging at 7.5 watts and Apple Watch charging at 2.5 watts. The built-in USB-C cable supports 20W fast charging, which is perfect when you need to top off your iPhone as fast as possible. You can charge two devices simultaneously, but it’ll slow down if you’re using both wired and wireless charging simultaneously. Still, for a battery this slim, it delivers more than enough power to get you through the day. Some of my favorite gear Abode Home Security System Abode is the best home security system and includes compatibility with HomeKit. With a 10,000mAh battery, the LISEN CardMag can fully charge your iPhone 1.5–2 times, depending on your phone’s battery size and usage during charging. Wrap up Overall, the LISEN CardMag is awesome. It might be the perfect battery. Qi2 support is the only thing I’m missing. I love the size, the built-in cable, and the display. With a 10,000mAh battery, it’s the ideal option for days when you’re out and about with no time to stop and plug in. You can buy it on Amazon in either black or grey.
