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 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.

The Charmast 10000mAh Portable Charger offers a convenient and versatile power solution, especially for those who travel frequently or use multiple devices. One of its standout features is the built-in cables, which include 3 output cables and 1 input cable, eliminating the need to carry separate cables. With a total of 6 outputs and 3 inputs, it supports charging up to 6 devices simultaneously, making it ideal for users with a variety of smartphones and tablets including iPhone, Samsung, Google Pixel, LG, and more.

The included digital LED display is a useful feature that allows you to monitor the remaining battery percentage accurately, preventing unexpected power loss. The slim design (5.68''x2.63''x0.69'') and lightweight build (0.53lb) enhance its portability, making it easy to carry around like a lighter phone. Fast charging capability ensures your devices get charged quickly, which is a significant advantage for busy users.

However, with a capacity of 10000mAh, this power bank may not be sufficient for extended trips or heavy usage without frequent recharges. Additionally, while the variety of built-in cables is convenient, it might not cater to users with specialized charging needs beyond the standard USB-C, Micro USB, and Lightning ports. This power bank is highly recommended for everyday use and travel, offering reliability and convenience for charging multiple devices.
