10 Best Portable Power Banks 2025 in the United States

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.

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 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.
