10 Best Power Banks 2025 in the United States

The Anker Nano Power Bank is a compact and ultra-slim portable charger with a 5,000mAh battery capacity, making it a good choice for light to moderate daily use like topping up your phone once or twice. Its standout feature is the MagSafe-compatible magnetic design, specifically optimized for iPhone Air, 17, 16, and 15 series, allowing for convenient wireless charging up to 15W. This means faster charging than many standard wireless power banks and makes it very handy if you want to avoid cables. It also supports 20W USB-C wired charging, enabling quicker recharge of the power bank itself and offering flexibility. The slim profile (only 0.3 inches thick) and lightweight design (about 6 ounces) make it very portable and easy to carry around comfortably. Safety is well addressed with features like temperature control and battery protection, keeping the device cooler and safer during use.

The 5,000mAh capacity is on the lower side compared to larger power banks, so it won’t fully recharge bigger devices or multiple devices multiple times. Also, it lacks multiple output ports, which limits charging more than one device at a time. Since it is designed mainly for iPhones with MagSafe, it’s less suitable if you have other phone brands like Pixel. This power bank is ideal if you prioritize sleekness, wireless MagSafe charging, and moderate power on the go, especially if you are an iPhone user who values portability and convenience over bulkier, higher-capacity options.

The Anker Laptop Power Bank offers a substantial 25,000mAh capacity, making it an excellent choice for long journeys or extended use, as it can charge multiple devices several times. With its triple 100W USB-C ports, it caters well to multitaskers who need to power devices like a MacBook and other gadgets simultaneously. This is a significant strength for users who rely on multiple devices throughout the day.

The power bank also features dual built-in and retractable cables, which are convenient for on-the-go use and enhance its portability. These cables are durable, with one extending up to 2.3 feet and capable of over 20,000 retractions, while the other acts as a carrying strap. This feature ensures that you have essential cables readily available and reduces the need to carry extra accessories.

Charging speed is another highlight, with the power bank capable of ultra-fast recharging to 30% in just 20 minutes, ensuring you spend less time waiting and more time using your devices. However, at 1.31 pounds and dimensions of 6.18 x 2.13 x 1.93 inches, it's relatively bulky and may not be the most portable option for users seeking a lightweight and compact power bank. Additionally, while it includes a USB-A port, the focus on USB-C might limit compatibility with older devices that primarily use USB-A. The Anker Laptop Power Bank proves to be a robust and versatile option for users who need reliable and fast charging for multiple devices, especially in professional or travel contexts.

The Anker Power Bank with a 20,000mAh capacity is a solid choice for those needing reliable and extended power on the go. It's capable of charging multiple devices simultaneously, distributing 87W of power across three ports, and can charge a single device at up to 65W. This makes it especially useful for users of power-hungry devices like laptops, including the MacBook Pro, which can be charged to 50% in under 40 minutes. The built-in USB-C cable is a convenient feature, designed to withstand over 10,000 bends, ensuring durability and longevity.

Additionally, the power bank itself recharges quickly in just 1.5 hours with a 65W charger, minimizing downtime between uses. At 15.5 ounces and dimensions of 6.2 x 2.89 x 1.02 inches, it strikes a balance between portability and high capacity, although it might be considered a bit bulky for some users. The digital display and over-charging protection add to its user-friendly design, providing peace of mind and ease of use.

Customer reviews are generally positive, with a 4.6 rating from over 1,400 users, highlighting satisfaction with its performance and reliability. However, it’s worth noting that while it is airline-approved, its weight and size might be a bit cumbersome for frequent travelers who prefer lighter, more compact options. The 18-month warranty and friendly customer service are additional perks, making it a trustworthy option. In brief, for users needing a high-capacity power bank with fast-charging capabilities and the ability to charge multiple devices, this Anker Power Bank is a strong contender.
