10 Best Wireless Battery Pack 2025 in the United States

The Anker Laptop Power Bank stands out with its massive 25,000mAh capacity, making it ideal for long trips and heavy usage. It features three 100W USB-C ports, allowing for simultaneous charging of devices, which is great for multitaskers. The additional USB-A port and dual built-in cables add to its versatility, allowing you to charge up to four devices at once. These cables are designed for durability with an extendable and retractable option, making it convenient for on-the-go use.

The power bank's high output power ensures fast charging, capable of recharging to 30% in just 20 minutes, which is highly impressive. Its compatibility is extensive, supporting a range of devices including the latest iPhone, MacBook, and various other smartphones and gadgets. The design complies with airline regulations for carry-on batteries, which is a plus for travelers. However, at a weight of 1.31 pounds, it is on the heavier side, which might affect portability for some users.

Despite this, the robust feature set and high capacity make it a strong choice for those needing reliable, multi-device charging on the go. The product is backed by an 18-month warranty and has received positive customer reviews, highlighting its reliability and performance. If you need a powerful, versatile battery pack and don't mind carrying a bit of extra weight, this Anker Power Bank could be a great option for you.

The Anker 621 Magnetic Portable Charger (MagGo) offers a compact and lightweight design with a 5,000mAh capacity, making it a good choice for casual users who want extra power on the go without carrying bulky chargers. Its standout feature is the strong magnetic attachment compatible with iPhone 12 through 16 models, which keeps the charger firmly in place and helps avoid disconnections during wireless charging. This makes it especially convenient for quick top-ups and using your phone hands-free at the same time. The included USB-C cable supports wired charging, adding some flexibility.

With a moderate battery capacity that won't fully recharge larger phones multiple times, it strikes a good balance for portability, slipping easily into pockets or bags. The charging speed is decent for a wireless pack of this size, although it may generate slight warmth during use, which is normal for wireless power conversion. This battery pack is best suited for iPhone users who value MagSafe compatibility and need a reliable, travel-friendly charger for daily use or short trips.

If you need a power bank for heavy usage or devices other than compatible iPhones, this model might fall short in capacity and versatility. It also doesn't offer fast charging beyond standard wireless speeds. However, for those seeking a neat, easy-to-use accessory that integrates seamlessly with their iPhone and delivers solid wireless charging on the move, the Anker 621 Magnetic Portable Charger is a strong choice.

The Anker Nano Power Bank is a compact and sleek wireless charger with a 5,000mAh capacity, making it a good option for light to moderate daily phone charging needs. Its ultra-slim design, just 0.3 inches thick, and lightweight build make it very portable and easy to carry around in a pocket or bag. It features 15W MagSafe-compatible wireless charging, which is fast enough to charge an iPhone 16 Pro up to 25% in around 42 minutes, offering a quick power boost when you’re on the go. The 20W USB-C output also allows for wired fast charging, adding flexibility.

Compatibility is focused on recent iPhone models with MagSafe; however, it is not designed to work with other brands like Pixel phones, which could limit usefulness if you have multiple devices. One standout feature is the enhanced safety and temperature control system, which keeps the battery cool and reduces the risk of overheating during charging. This makes it safer for daily use compared to some competitors.

On the downside, the 5,000mAh capacity is on the lower end compared to some larger power banks, so it may not fully recharge your phone multiple times. Also, wireless charging speeds max out at 15W, which is decent but not the fastest available. This power bank is a great choice for iPhone users who want a stylish, easy-to-carry charger with reliable wireless performance and safety features, but it is less suited for users needing higher capacity or multi-brand compatibility.
