10 Best Portable Chargers 2025 in the United States

The Anker Nano Power Bank is a slim and lightweight portable charger with a 5,000mAh battery capacity, making it easy to carry without adding much bulk. It’s designed especially for iPhone users with models from the iPhone 15 to 17 series, thanks to its Qi2 MagSafe compatibility. This allows it to attach magnetically to your phone for convenient wireless charging at up to 15W, enabling a quick battery boost—for example, charging an iPhone 16 Pro to about 25% in around 42 minutes. Besides wireless charging, it supports 20W USB-C wired input, allowing the power bank itself to recharge relatively fast compared to many other portable chargers in this size range.

A standout feature is the focus on safety and temperature control. Using graphene cooling and smart chips, it stays cooler than typical power banks during use, which benefits both your device and the charger’s lifespan. It also offers continuous battery protection to prevent overheating or other electrical issues.

The 5,000mAh capacity may be considered low if you need to charge larger phones or multiple devices fully while on the go. Additionally, it is specifically tailored for iPhones with MagSafe, so it may not work as efficiently—or at all—with other brands like Pixel phones. The single USB-C port is convenient but limits charging multiple devices simultaneously. This power bank is a strong choice for those prioritizing a slim, portable design with fast, safe wireless charging for newer iPhones. For users needing higher capacity or more versatile port options, especially for non-MagSafe phones, other power banks might be more suitable.

The INIU Portable Charger stands out for being one of the lightest 10,000mAh power banks on the market, weighing just 8.8 ounces and featuring a slim, compact design that's easy to carry around. Its capacity of 10,000mAh is a solid middle ground, enough to charge most smartphones fully once or twice, making it suitable for daily use or short trips. A notable strength is the dual USB-C ports allowing both input and output, which is uncommon and very convenient since you can charge the power bank and your devices with the same USB-C cable.

Along with a USB-A port, it supports charging up to three devices simultaneously, which is great in emergencies or when traveling with multiple gadgets. The charger features fast charging with a powerful 45W output, capable of charging an iPhone 15 to 60% in just 25 minutes, so it's efficient for quick top-ups. Safety is emphasized through high-grade materials and a reputation for safe charging among millions of users.

On the downside, while 10,000mAh is versatile, it might not be enough for heavy users who want multiple full charges or to power larger devices like tablets heavily. The power bank is also slightly thicker compared to ultra-slim models, although this is a trade-off for higher capacity and more ports. It includes useful extras like an indicator light and a flashlight, but no wireless charging. This charger is a practical choice for those who want fast, safe charging in a compact, lightweight package with flexible port options.

This portable charger from Charmast offers a convenient and versatile solution with its 10000mAh capacity. Its standout feature is the built-in cables, meaning you don’t need to carry extra cords for different devices. With 6 outputs and 3 inputs, it's highly flexible and can charge up to six devices simultaneously, making it a great option for users with multiple gadgets, including iPhones, Androids, and tablets.

The super slim design, comparable to the size of a lighter cellphone, ensures easy portability, weighing only 0.55lb. The digital LED display is a handy feature that shows the remaining battery percentage accurately, removing any guesswork about when you need to recharge it. However, while the capacity is decent, it may not suffice for heavy usage or long trips without frequent recharges.

Additionally, the inclusion of various input options is convenient, but it may confuse some users who are looking for a straightforward charging method. The charger comes with a pouch and user manual, and the brand offers 18 months of support along with lifetime technical support, which is a reassuring aspect. This product is especially beneficial for frequent travelers or anyone who juggles multiple devices and prefers not to carry various charging cables.
