10 Best Thin Portable Charger 2025 in the United States

The Charmast 10000mAh Portable Charger stands out with its built-in cables, making it extremely convenient for users who prefer not to carry multiple cables. With a total of 6 output ports (3 of which are built-in) and 3 input options, it can charge up to 6 devices concurrently, making it ideal for multi-device users.

The slim design, comparable to a lightweight smartphone, enhances portability, and the digital LED display allows for easy monitoring of the remaining battery charge. Compatibility is broad, covering a wide range of popular devices including iPhones, Samsung phones, Google Pixels, and various tablets. The inclusion of a pouch and comprehensive support adds value to the purchase.

With a capacity of 10000mAh, it may not be sufficient for heavy users who need to charge multiple high-consumption devices frequently. Additionally, the charging speed, while decent at 3A, might not be the fastest available in the market. The build quality appears respectable, but detailed safety features are not explicitly mentioned, which could be a concern for some users. This charger is best suited for travelers or anyone who needs a compact and versatile charging solution on the go.

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.

The Anker Nano Power Bank stands out as a highly portable option for Apple users thanks to its built-in Lightning connector, eliminating the need to carry extra cables. Its 5,000mAh battery capacity offers a decent boost—enough to add approximately 20 hours of video playback, which is quite handy for day trips or short outings. Weighing just 3.5 ounces and small enough to fit comfortably in your pocket, it excels in the size and weight department for a thin portable charger.

The 12W fast charging output is reliable for quickly topping up your iPhone 12, 13, or 14 series devices, and being MFi certified ensures safe and efficient charging without compatibility worries. However, the 5,000mAh capacity is on the lower side compared to larger power banks, so it won’t fully recharge larger devices multiple times. Also, it has only one output port, limiting simultaneous device charging.

The build quality is solid and backed by an 18-month warranty, which adds peace of mind. If you prioritize ultra-portability and seamless Apple device compatibility over bulk battery power or multi-device charging, this charger is a smart, convenient choice.
