10 Best Thin Portable Charger 2025 in the United States

The INIU Portable Charger is an excellent choice for those needing a thin and portable power bank with a substantial capacity of 10000mAh. This slim, lightweight charger measures just 0.5 inches thick and weighs 7 ounces, making it easy to slip into a pocket or bag. It can efficiently charge devices multiple times, such as topping up an iPhone 8 up to 3.6 times or a Samsung S22 1.8 times, which is impressive for its size. The charger includes both USB-C and USB-A ports, allowing versatile charging options for various devices.

One standout feature is its high-speed 3A charging, which can fuel an iPhone up to 78% in one hour, making it ideal for users needing quick power boosts on the go. The charger employs INIU's AutoFit technology to optimize charging speed based on the device, ensuring efficient energy use. Safety is a significant plus with this power bank, as it incorporates a 15-layer SmartProtect system to prevent overheating and battery damage, providing peace of mind to users.

The build quality is robust, and the manufacturer offers an industry-leading 3-year warranty, showcasing confidence in their product's durability. However, some potential drawbacks include the relatively short USB-C cable provided (0.3 meters), which might not be convenient for all users. Additionally, despite its high capacity, the power bank may feel a bit bulky for users looking for ultra-compact solutions. Nevertheless, for those who prioritize safety, fast charging, and a decent capacity in a portable form, the INIU Portable Charger is a strong contender.

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 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.
