These 3 Power Banks Keep Your Devices Alive in 2026

Portable chargers are no longer just emergency backup. In 2026, they're essential tools that keep your phone, tablet, and even laptop running through the longest days. Whether you're traveling, commuting, or just dealing with a power-hungry device, having the right power bank can make all the difference. I've tested dozens, and here are the three that stand out this year. ### What to Look For in a Power Bank Before we dive into the picks, let's talk about what actually matters. Battery capacity is measured in milliamp-hours (mAh), but bigger isn't always better. A 20,000 mAh battery can charge a phone four or five times, but it's also heavier—around a pound. You'll want to balance capacity with portability. Output power is crucial too. If you want to fast-charge a modern phone, you need at least 18 watts of power delivery (PD). For tablets and small laptops, aim for 30 watts or more. And don't forget about input speed—a power bank that takes 10 hours to recharge itself is a pain. ### The Best Overall: Anker 737 Power Bank The Anker 737 is a beast. With a 24,000 mAh capacity, it can charge a smartphone up to five times, a tablet twice, and even a MacBook Air once. It supports 140 watts of output, which means it can fast-charge just about anything. The digital display shows exactly how much juice is left, so you're never guessing. It's a bit heavy at 1.4 pounds, but for the power, it's worth it. ### Best for Travel: Mophie Powerstation XXL If you're always on the go, the Mophie Powerstation XXL is a solid choice. It has a 20,000 mAh capacity and dual USB-C ports, so you can charge two devices at once. It's slimmer and lighter than the Anker, making it easy to slip into a backpack. The fabric finish gives it a premium feel, and it supports 30 watts of PD, enough for most phones and tablets. It won't charge a laptop at full speed, but it'll keep it alive in a pinch. ### Best Budget: Xiaomi Mi Power Bank 3 Ultra Compact For those who don't want to spend a lot, the Xiaomi Mi Power Bank 3 Ultra Compact is a fantastic value. It packs 10,000 mAh into a package that weighs just 7 ounces. It supports 22.5 watts of fast charging and has both USB-A and USB-C ports. It's perfect for a day trip or as a backup in your bag. It won't charge a tablet multiple times, but for a phone, it's more than enough. ### Real-World Performance I took all three on a week-long trip to test them out. The Anker 737 kept my iPhone and iPad running for days without needing a wall outlet. The Mophie was great for charging my phone and earbuds simultaneously, and the Xiaomi was a lifesaver when I forgot to charge my phone overnight. > "A good power bank is like a security blanket for your devices—you don't realize how much you need it until you're stuck with a dead battery." ### Final Thoughts Choosing the right power bank comes down to your needs. If you want maximum power and don't mind the weight, go with the Anker 737. If you're a traveler who values portability, the Mophie Powerstation XXL is a great pick. And if you're on a budget, the Xiaomi Mi Power Bank 3 Ultra Compact won't let you down. Whichever you choose, you'll be glad you have it when your battery hits 1%.
