10 Best Portable Charger Power Banks 2025 in the United States

The Anker Power Bank with a 20,000mAh capacity is a solid choice for anyone needing a reliable portable charger for travel or daily use. Its large battery can keep your devices powered for an extended time, which is especially convenient if you're away from outlets for a while. One standout feature is the built-in USB-C cable, which saves you from carrying extra cords and is designed to be tough enough to handle many bends.

The charger supports fast charging, delivering up to 87W across three devices, with one able to receive as much as 65W — this means it can quickly juice up not just phones like iPhone 15 or Samsung models but also larger gadgets like a 14" MacBook Pro. It even recharges itself fully in about 1.5 hours when using a 65W charger, which is quite efficient for a power bank of this size. The digital display helps you easily see how much charge is left, and safety features like overcharge protection add peace of mind.

On the downside, at 15.5 ounces and over 6 inches long, it’s a bit bulkier and heavier than smaller, lower-capacity models, which might be less comfortable for pocket carry. While it has three output ports, one is the built-in cable, so you don’t get three separate cables for different devices. This might limit flexibility if you want to charge multiple different devices without extra cables. This power bank is an excellent option for users who want a powerful, fast charger with convenience features and are comfortable carrying a slightly larger unit.

The Anker PowerCore 10K is a compact and lightweight portable charger with a 10,000mAh capacity, making it great for travelers and anyone needing reliable power on the go. It can charge an iPhone 15 about twice and a Galaxy S23 nearly twice, which is sufficient for daily use or short trips. The slim design and light weight (just 8.6 ounces) make it easy to carry in pockets or bags without bulk.

It offers two output ports: a USB-C port that works for both input and output, and a USB-A port, giving flexibility to charge different devices. The USB-C port supports fast 5V/3A charging, helping devices recharge quicker than standard chargers. Its build is tough, with scratch resistance and a drop-test certification, which means it can handle everyday bumps and falls.

With 10,000mAh capacity, it might not fully charge larger devices like tablets multiple times or support charging multiple high-power devices simultaneously for long periods. Also, it has only two ports, so it may not be ideal for users needing to charge many devices at once. This power bank suits anyone looking for a reliable, travel-friendly charger with decent capacity and durability but may not meet heavy users who require higher capacity or more charging ports.

The Anker 621 Magnetic Portable Charger (MagGo) is a compact and lightweight power bank with a 5,000mAh capacity, making it suitable for topping up an iPhone once or providing extra power on the go. Its standout feature is the built-in strong magnets that attach securely to the back of iPhone 12 through 16 models, allowing wireless charging without worries about alignment and disconnection. This makes it very convenient for casual phone users who want a hassle-free charging experience without cables.

The charger uses USB-C for input, supporting faster recharge of the power bank itself. Weighing just 5 ounces and slim enough to fit in a pocket or purse, it’s designed for portability and ease of use. However, its 5,000mAh capacity is on the lower side compared to larger power banks, so it may not fully charge bigger phones multiple times or power other devices. Also, it lacks multiple output ports, meaning you can only charge one device at a time. Some users might find the wireless charging heat generation noticeable but within safe limits.

This charger is an excellent option for iPhone users who value convenience and portability over high capacity or multiple device charging.
