When a 10,000mAh bank is not enough, the next step up is the one that gets you through a weekend or a flight, and a built-in USB-C cable saves you carrying a second thing. Six power banks over 10,000mAh are in this guide, listing between $30 and $80, and all are non-magnetic. If you want something more pocketable, start with our built-in cable power banks up to 10,000mAh.
Prices below are list prices. Five of the six are rated at 45W, which Samsung's fastest phones can use. One note for Galaxy owners: Anker says its 45W Samsung Fast Charging is only available through the USB-C port, not the built-in cable, so keep that in mind.

Anker says this bank has two built-in USB-C cables, tested for over 10,000 bends, plus a USB-C port and a USB-A port, so it can charge four devices at once. Anker rates it at 45W and says it gives about four full charges for an iPhone 16.
Anker lists it at 12.85 oz.

Street prices on Amazon change often and can sit below these list prices, so check the current price before you buy, and keep an eye out for promotions. We're still waiting to see how the brands' output and size claims hold up, and it'll be worth seeing how they perform in real-world use.
