10 Best Lightweight Portable Power Bank 2025 in the United States

The Anker PowerCore 10K is a great choice if you want a compact and light power bank that still holds a solid 10,000mAh capacity. It can comfortably recharge an iPhone 15 about twice and offers nearly two full charges for a Galaxy S23, making it handy for daily use or short trips. Its slim design and light weight (just under 9 ounces) make it easy to carry in a pocket or bag without adding bulk.

You get two output ports—a USB-C that doubles as input for faster recharging of the power bank itself, and a USB-A port—offering flexibility for different devices. Charging speed is decent with PowerIQ technology and 5V/3A output, so your phone won’t take forever to top up. The build feels sturdy and durable, passing a drop test from over 3 feet, plus it has scratch resistance, which is reassuring for travel.

A 10,000mAh capacity is enough for everyday needs but might be limiting if you want to charge multiple devices several times or larger tablets. Also, it doesn’t support wireless charging despite that being mentioned, so you’ll need cables. If you want a budget-friendly, reliable power bank that's easy to carry and charges quickly via USB-C, this Anker model is a solid pick, especially in a two-pack for sharing or backup.

The Anker 25,000mAh Laptop Power Bank is a solid choice if you're looking for a powerful yet portable charger. Its large capacity means you can charge devices multiple times, which is great for long trips or heavy use. It stands out with three USB-C ports, each capable of delivering 100W of power, allowing you to charge multiple laptops or phones quickly at the same time. Additionally, it includes two built-in USB-C cables—one retractable and one short strap-style—making it convenient to carry and use without needing extra cables. The power bank can charge up to four devices simultaneously thanks to an extra USB-A port, which is handy if you have a mix of old and new gadgets. Charging the power bank itself is fast; it reaches 30% capacity in just 20 minutes.

Despite its high capacity and power, it weighs just over 1.3 pounds and remains compliant with airline carry-on rules, so it's travel-friendly. Build quality is reassuring, with durable cables tested for thousands of uses and safety features typical of Anker products. The main downside could be its size—it's bulkier than smaller capacity models, so it might not fit comfortably in all pockets. Also, while it supports many devices, the focus on USB-C might require adapters for some older devices.

This power bank is ideal for frequent travelers or professionals who need reliable, multi-device charging on the go without sacrificing speed or convenience.

The Anker 621 Magnetic Portable Charger is designed with portability in mind, featuring a slim, lightweight build that easily snaps onto the back of compatible iPhones using strong magnets. Its 5,000mAh battery capacity offers enough power to top up your phone once or keep it charged throughout a day of moderate use, making it suitable for users who want convenience on the go without bulk. The wireless charging feature is a standout, allowing you to charge your iPhone without cables, and the magnetic alignment helps prevent common issues like disconnections during charging. It also includes a USB-C port and cable, which can be useful for charging other devices or recharging the power bank itself.

While the charging speed is solid for its size, it’s not the fastest compared to larger power banks, so it might not be ideal if you need rapid recharging. The build quality feels sturdy, and the device meets international safety standards, though it can get warm during use—which is normal but worth noting.

This power bank makes a great choice for iPhone users looking for a compact, easy-to-carry battery that integrates seamlessly with their device for everyday use. However, if you need more power capacity or faster charging for multiple devices, you might want to consider larger options.
