The Anker Nano is our top pick for most travelers. It hits the sweet spot of compact size, fast charging, and flight safety. The built-in retractable USB-C cable means one less thing to forget, just pull, plug, and charge. It can fast-charge an iPhone 16 Pro to 50% in just 27 minutes, and fits comfortably in a jacket pocket or small purse. The smart display shows exact battery percentage so you always know how much power is left.

If you want a simple, no-fuss power bank that just works, the Anker PowerCore 10K is legendary for a reason. Over 50 million Anker power banks sold worldwide, and this compact model is smaller than a deck of cards. It won't fast-charge your laptop, but it will reliably give your phone 2-3 full charges without weighing down your bag. Perfect for short trips or as a lightweight backup charger.

Frequent flyer with a laptop? This is your power bank. The INIU 65W packs 20,000mAh of capacity, enough for 4-5 phone charges or a full laptop top-up, while staying well within the 100Wh TSA limit at 73Wh. The built-in display shows battery level and charging status at a glance. With three USB ports, you can charge your phone, tablet, and earbuds simultaneously.

iPhone user? This is the one to get. The Anker MagGo snaps magnetically to the back of your iPhone 12-17 and charges wirelessly at 15W via Qi2, no cables needed at all. The ultra-slim design and foldable stand let you prop your phone up in landscape mode during the flight. It's the most elegant travel charging solution for iPhone users, and it's TSA-compliant at just 37Wh.

If you hate bulky bags and want a power bank that barely takes up any space, meet the LISEN Ultra Slim. At just 0.5 inches thick and made from aircraft-grade aluminum alloy, it's genuinely one of the thinnest TSA-approved power banks available. It's CCC certified, TSA compliant, and the premium metal finish looks great. The external display shows battery level without opening any app. Ideal for minimalist travelers who prioritize portability above all else.
