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 iPhone 16 Portable Charger is a compact and stylish power bank designed with portability in mind. Its 5,000mAh capacity is enough to give your iPhone 15 or similar devices a good boost during the day, making it a great choice for light to moderate phone users who need extra juice while on the move. The built-in USB-C connector is a standout feature, helping you avoid tangled cables and keep things neat, which is especially handy for travel or daily carry.

The charger supports up to 22.5W fast charging via dual USB-C ports with PowerIQ 3.0 technology, so your devices charge quickly compared to many standard power banks. At just 3.5 ounces and about 3 by 1.5 inches, it easily fits in your pocket or purse without adding bulk. On the downside, the 5,000mAh capacity means it won't fully recharge larger devices like iPads more than once or power multiple devices extensively without recharging itself.

Also, while the build quality is solid and backed by a 24-month warranty, the charger lacks wireless charging features and might be less suited for users needing higher capacity or multiple output types. This power bank is an excellent fit for those who prioritize slim design, fast charging for phones, and convenience, but it may not cover more demanding charging needs.
