10 Best Portable Phone Chargers 2025 in the United States

The Anker MagGo Power Bank is a slim and lightweight portable charger with a 10,000mAh capacity, offering around 1.8 full charges for recent iPhone models. It features a magnetic wireless charging capability that works best with the iPhone 12 through 16 series, delivering fast 15W wireless charging. Additionally, it includes a 30W USB-C port for wired charging, which is convenient for quickly topping up your phone or other devices.

Its compact size and light 7-ounce weight make it easy to carry without feeling bulky. The charger has a premium feel due to its sturdy metal frame and thermal insulation that helps keep it cool during use. If you have an Android phone or an iPhone outside the compatible models, the magnetic feature and fastest wireless charging speeds will not be available—charging will occur at slower speeds and without magnet alignment. The power bank includes only one USB-C port, so you cannot charge multiple wired devices simultaneously.

This power bank is well suited for iPhone users seeking a sleek, portable charger with fast magnetic wireless charging and decent capacity. However, those needing more ports or broader device compatibility might want to consider other options.

This portable charger offers a solid 10,000mAh capacity, making it suitable for charging most smartphones once or even twice, depending on the device. One of its standout features is the built-in cables — it includes three output cables supporting iPhone, USB-C, and Micro USB devices, plus additional USB ports, allowing you to charge up to six devices at the same time. This is great for people who carry multiple gadgets or share charging with friends without needing to bring extra cables.

It weighs just under 9 ounces and is slim enough to fit comfortably in a bag or large pocket, so it’s very travel-friendly. The charger also features a clear digital LED display that shows exactly how much power is left, removing guesswork so you know when to recharge it. It supports three input types for recharging itself, giving you flexibility depending on what charger or cable you have on hand.

For everyday users who need reliable, versatile charging on the go and appreciate built-in cables to reduce clutter, this power bank is a practical choice. Those who prioritize very fast charging for multiple devices at once or have larger devices like tablets might want to consider higher-capacity options.

The Anker 621 Magnetic Portable Charger (MagGo) is a compact and lightweight power bank, boasting a 5,000mAh capacity that's convenient for on-the-go charging. It uses Anker's MiniCell technology, allowing it to be smaller and lighter without compromising on charging performance. This makes it an excellent choice for those who prioritize portability and ease of use.

The strong magnets ensure it stays attached to the back of your iPhone (compatible with iPhone 12 through 16 series), making it handy for everyday activities like taking selfies or making calls. It’s designed to align perfectly with your phone, reducing the common issue of disconnection during wireless charging. However, users should be aware that slight heating can occur during use, which is normal due to efficiency losses in the conversion circuit.

The 5,000mAh capacity is suitable for partial charges or to extend your phone's battery life, but it may not fully charge your device multiple times. With its USB-C connectivity, it ensures fast and efficient input charging. Additional features include a 23.6-inch USB-C to USB-C cable, a 24-month warranty, and strong customer service support. On the downside, the device only offers one USB Type-C port, which might limit its use for charging multiple devices simultaneously. Weighing just 5 ounces and measuring 4.13 x 2.62 x 0.45 inches, it’s designed for ultimate portability.
