10 Best Portable Power Banks 2025 in the United States

The INIU Portable Charger is a well-designed power bank that offers a 10,000mAh capacity, making it a solid choice for everyday use and short trips where you need to recharge your phone or tablet on the go. What sets it apart is its compact size and light weight — it's about 30% smaller and 15% lighter than many other power banks with similar capacity, which makes it easy to carry in a pocket or bag.

It supports fast charging with a powerful 45W output, so you can quickly boost compatible devices like the iPhone 15 or Samsung Galaxy series. Uniquely, it has two USB-C ports plus one USB-A port, allowing you to charge three devices at once, which is convenient if you carry multiple gadgets. Both USB-C ports can be used for input (to charge the power bank) and output (to charge your devices), which is rare and adds flexibility.

With 10,000mAh, it won’t fully recharge very large tablets multiple times or serve well for extended power needs compared to higher-capacity banks. While it includes some handy extras like indicator lights and a flashlight, it doesn’t offer wireless charging or solar power, which some users might look for. The build quality is solid with safety features and a 3-year warranty, contributing to reliability. If you need a slim, fast, and versatile power bank for daily phone charging and occasional multi-device use, the INIU is a smart pick.

The Anker Prime Power Bank is a strong choice if you need a high-capacity and fast-charging portable charger. With 26,250mAh capacity, it holds plenty of power to keep devices like MacBook Pros and iPhones charged during busy days or travel. One standout feature is its high output of up to 300W shared across three ports—two USB-C and one USB-A—allowing you to charge multiple devices quickly. For example, it can charge a MacBook Pro to half power in under 30 minutes when using the right cable. It also supports very fast recharging itself, reaching 50% charge in just 13 minutes, which is rare in portable chargers and great if you’re on the go.

The digital display and app control offer useful info about battery status and let you adjust power output, adding convenience and control. Weighing about 1.33 pounds and fairly compact, it’s TSA-approved for air travel, making it a solid travel companion. However, the power bank is a bit heavier and larger than simpler models, which might be less ideal for those seeking something ultra-light or pocket-sized. Also, while the 300W output is excellent for laptops and phones, it might be overkill if you only need a charger for smaller devices.

The included accessories are minimal, and the base for recharging is sold separately, which could add to the overall cost. This power bank suits travelers and professionals who need fast, reliable charging for multiple high-power devices, but it may be more than what casual phone users require.

The Anker Laptop Power Bank is a high-capacity portable charger with a substantial 25,000mAh battery, making it ideal for those who need to keep multiple devices charged on the go. It features three USB-C ports, each capable of delivering up to 100W, allowing simultaneous charging of devices such as a MacBook and smartphones. This power bank is particularly useful for travelers or individuals who use multiple devices daily, as it complies with airline carry-on regulations for batteries under 100Wh and includes built-in and retractable cables for convenience.

The dual built-in cables are a thoughtful addition, with one extending up to 2.3 feet for flexible use and the other serving as a durable carrying strap. Additionally, the power bank supports fast recharging, reaching 30% capacity in just 20 minutes, which is a significant advantage for quick top-ups. However, its size (6.18 x 2.13 x 1.93 inches) and weight (1.31 pounds) may be on the bulkier side for some users, potentially making it less convenient to carry in smaller bags or pockets.

Despite this, the ability to charge up to four devices at once (including smartphones, tablets, and other USB-enabled devices) makes it a versatile option for power users. Backed by an 18-month warranty and strong customer service, the Anker Laptop Power Bank is a reliable choice for those seeking substantial and versatile portable power.
