10 Best Power Banks 2025 in the United States

The Anker Zolo Power Bank is a robust portable charger with a substantial 20,000mAh capacity, making it a solid choice for those who need to keep their devices powered during long trips or extended use periods. This power bank can charge an iPhone 15 up to four times or a Samsung S24 nearly four times, which is highly convenient for heavy phone users or travelers. Its 30W fast charging capability is impressive, allowing you to charge devices quickly and keep them ready for use. For instance, it can boost an iPhone 15 from 0 to 57% in just 30 minutes, which is ideal for quick top-ups when time is tight.

The built-in USB-C cable is a thoughtful addition, offering convenience and reducing the need for carrying extra cables. Moreover, its durability is enhanced, designed to withstand over 10,000 bends, ensuring long-term reliability. The power bank's safety is a critical feature, with ActiveShield 2.0 technology that continuously monitors temperature and adjusts power output to prevent overheating and ensure safe charging.

However, the power bank's size and weight might be a consideration for some users, as larger capacity often means a bulkier device. It's also worth noting that while it includes a built-in USB-C cable and one USB-C and one USB-A port, users needing multiple devices charged simultaneously may find this limiting. Its high capacity, fast charging, and safety features make the Anker Zolo Power Bank a dependable option for those in need of reliable power on the go.

The INIU Portable Charger is a solid choice for users looking for a blend of capacity, portability, and fast charging. With a 10000mAh capacity, it offers ample power to charge devices multiple times, making it useful for short trips and outings. The charger stands out as one of the thinnest in the market at just 0.5 inches thick and weighing 8.8 ounces, making it extremely portable and easy to carry around in pockets or small bags.

It has both USB Type-C and USB Type-A ports, supporting a wide range of devices and offering versatility in charging options. The USB-C port serves as both an input and an output, a feature not common in many power banks, enhancing its utility. With a 3A high-speed charging capability, it can quickly charge devices, which is particularly beneficial for users needing to boost their device's battery in a short amount of time.

Additionally, the power bank includes a flashlight, adding another layer of functionality, especially in emergencies. Safety is another strong point, with INIU's 15-layer SmartProtect system that guards against overheating and battery damage. However, the 10000mAh capacity, while decent, may not be adequate for heavy users who need to charge multiple high-capacity devices frequently. The included cable is quite short at 0.3 meters, which might not be convenient for all users. Despite these minor downsides, the INIU Portable Charger offers a combination of slim design, high-speed charging, and safety features, making it a reliable companion for day-to-day use and travel.

The Anker Zolo Portable Charger, with its 10,000mAh capacity, is a robust option for anyone in need of a reliable power bank, particularly useful for travel. It has enough power to fully charge an iPhone 15 twice and a Samsung S24 nearly twice, making it a great companion for those on the go.

The standout feature here is the 30W fast charging capability, which is impressive and allows for rapid charging of devices, including iPhones, MacBooks, and more. The built-in USB-C cable is both convenient and durable, tested to withstand over 10,000 bends, which adds to its longevity and usability.

Additionally, the bi-directional charging feature, offering 30W output and 20W input, ensures quick charging both ways, which is a significant advantage for users who need to charge the power bank itself in a hurry. However, there are some drawbacks. The power bank is relatively heavy at 7.7 ounces and might feel a bit bulky for its size (4.32 x 2.58 x 0.98 inches). It also lacks additional output ports beyond the built-in USB-C, limiting its ability to charge multiple devices simultaneously. Despite these minor shortcomings, the Anker Zolo Portable Charger is an excellent choice for those who need a fast-charging, high-capacity power bank, especially for travel and heavy usage scenarios.
