10 Best Power Banks 2025 in the United States

This magnetic portable charger offers a solid 10,000mAh battery capacity, which is enough to recharge most smartphones about two times, making it a practical choice for daily use or travel. Its standout feature is the strong built-in magnets that let your iPhone snap securely to the charger for wireless charging, providing convenience without tangled cables. It supports fast charging up to 20W on wired connections (via USB-C and USB-A ports), which helps refill your devices quickly, plus 15W wireless charging, suitable for compatible iPhones.

The charger is compact and lightweight, fitting easily into pockets or bags — a big plus for travelers. An easy-to-read LED display shows exactly how much battery is left, so you’re never caught off guard. Safety is well-covered with protections against overcharging, short circuits, and overheating, which helps keep your devices and the power bank safe.

This charger is an excellent fit for iPhone users who want a portable, easy-to-use charger that combines wired and wireless options with fast charging and solid safety features. However, while 10,000mAh is good for everyday use, it may not be enough for longer trips without access to power. The wireless charging speed is lower than wired, so charging wirelessly takes longer. Also, the magnetic feature works best with iPhones that support MagSafe; other phones may not benefit from this convenience.

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 Prime Power Bank stands out for users needing a powerful and fast-charging portable charger. With a large 26,250mAh capacity, it can recharge laptops like the MacBook Pro nearly once and rapidly charge smartphones such as the iPhone 16 Pro to 50% in under half an hour. Its 300W maximum output spread across two USB-C ports and one USB-A port is impressive, allowing simultaneous charging of multiple high-demand devices. The 140W fast charging via USB-C is particularly useful for quickly topping up laptops or phones, and the 250W input charging speed helps the power bank itself recharge quickly—a real time-saver if you use it heavily throughout the day. Its TSA-approved battery size means it’s airline-friendly, making it a good choice for travelers who rely on multiple devices on the go. The power bank is fairly compact and lightweight at just over 1.3 pounds and roughly 6 by 2.5 by 1.5 inches, striking a balance between capacity and portability.

Unique features like the smart digital display and app control add convenience by letting users monitor power status and adjust output manually. While the power bank can charge a MacBook Pro almost fully, it might not be enough for extended laptop use without recharging itself. The base for charging is not included, which is an additional purchase for some users. This model does not support wireless device charging despite some references to wireless display features. It suits tech-savvy travelers and professionals needing fast, multiple-device charging in a portable form, but casual users who prioritize wireless charging or an ultra-lightweight design might prefer other options.
