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 Power Bank with a 20,000mAh capacity is a robust choice for anyone needing a portable power solution for their devices. It's equipped with 2 USB-C ports and 1 USB-A port, which allows you to charge multiple devices simultaneously. The highlight is its 87W fast charging capability, which can rapidly charge a variety of devices, including laptops, iPhones, and Samsung phones. A built-in USB-C cable adds convenience and durability, designed to withstand over 10,000 bends. This makes it very user-friendly, minimizing the need for carrying extra cables.

The power bank itself can be fully recharged in just 1.5 hours with a 65W charger, which is quite efficient for such a high-capacity device. Additionally, the 20,000mAh capacity ensures extended use, so you won’t have to worry about running out of battery on your devices during long trips. It's also approved for airline travel, adding to its portability benefits. The build quality is solid, with a durable design that can handle everyday wear and tear. Weighing 15.5 ounces and measuring 6.2 x 2.89 x 1.02 inches, it’s compact enough to carry around but slightly on the heavier side compared to some other power banks.

The digital display and overcharging protection are useful features that add to its safety and ease of use. However, the weight might be a minor drawback for those looking for a super lightweight option. The product has received positive feedback, boasting a 4.6 out of 5-star rating from over 1,400 reviews, indicating strong customer satisfaction. The included 18-month warranty and friendly customer service from Anker are additional positives. This power bank is highly suitable for users who need reliable, fast, and high-capacity charging on the go, especially for those who use multiple devices regularly.

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.
