10 Best Thin Portable Charger 2025 in the United States

The Anker Nano Power Bank is a solid choice if you want a slim and lightweight portable charger that fits easily in your pocket or bag. It offers a modest 5,000mAh battery capacity, which is enough to give your phone a decent boost during the day without adding bulk. Weighing just under 4 ounces and only 0.3 inches thick, it's one of the more portable options available. This power bank shines with its Qi2-certified wireless charging, supporting up to 15W MagSafe-compatible fast wireless charging, which means you can charge your iPhone 16 Pro up to 25% in about 42 minutes.

For wired charging, it has a USB-C port that can deliver up to 20W output, allowing for faster charging if you prefer a cable. Safety is well addressed here too, with smart heat control and cooling technology keeping the device cool and safe during use, which is better than many competitors. However, the 5,000mAh capacity may not be enough if you need to fully recharge larger phones multiple times or charge other devices.

Also, if you want multiple output ports to charge more than one device at the same time, this model might fall short since it primarily focuses on wireless charging and a single USB-C port. To sum up, this Anker power bank is a great pick for iPhone users who prioritize portability and wireless convenience with reliable safety features, but it may not suit those needing higher battery capacity or multi-device charging.

The INIU Portable Charger is a compact and lightweight power bank with a 10,000mAh capacity, making it a solid choice for those who need reliable on-the-go charging without carrying a bulky device. Thanks to its high-density battery cells, it is about 30% smaller and 15% lighter than similar capacity chargers, weighing just 6.4 ounces and fitting easily in a pocket or small bag. Its standout feature is the 45W fast charging capability, allowing an iPhone 15 to reach 60% charge in about 25 minutes, which is impressive for a charger this size.

The power bank supports charging three devices simultaneously through two USB-C ports and one USB-A port, providing versatile compatibility for multiple gadgets. It also offers dual USB-C ports that work both for input and output, which is a bit rare and handy for using standard USB-C cables for both charging the power bank and your devices. Built with safety in mind, it uses high-grade materials and has over 38 million users trusting its safe charging technology.

While 10,000mAh is enough for a day or two of casual use, it may not fully recharge larger tablets or multiple heavy-use devices multiple times. Its thickness of 0.7 inches may be slightly noticeable compared to ultra-thin models, though it remains very portable. This power bank is an excellent fit for travelers, students, and everyday users who want quick charging and the ability to power several devices without extra bulk, combined with solid safety features and a durable build.

The Anker 621 Magnetic Portable Charger (MagGo) is an impressive choice for a thin portable charger, especially tailored for iPhone users. With a capacity of 5000mAh, it provides a decent amount of power to extend your phone’s battery life, though it might be insufficient for multiple charges if you have a high usage rate. The inclusion of a USB-C cable is a positive, enhancing versatility and compatibility with various devices.

Its size and weight are major strengths; at just 5 ounces and with dimensions of 4.13 x 2.62 x 0.45 inches, it's very compact and easy to carry, fitting comfortably in pockets or small bags. The wireless charging feature, combined with strong magnets, ensures it stays attached to your iPhone securely, making it convenient for everyday use, like taking selfies or making calls single-handedly. However, some users might experience slight heating during use, which is normal but worth noting.

In terms of build quality and safety features, Anker is known for its reliable products, and the 24-month warranty adds extra peace of mind. The charger ranks high in customer reviews with a 4.2-star rating, reflecting general satisfaction. While it excels in portability and convenience, the charging speed might not be the fastest available due to its miniaturization, but it’s adequate for emergency charging needs. This product is ideal for iPhone users looking for a compact, reliable, and easy-to-use portable charger.
