To charge an Anker Power Bank, connect the included USB cable to the power bank's USB port and plug it into a compatible USB source such as a wall adapter, computer, or smartphone. Ensure the USB port is properly seated and the cable is securely fastened. For optimal charging speed, use a USB Power Delivery (PD) adapter if the power bank supports it. Avoid using damaged cables or non-certified chargers to prevent overheating or reduced efficiency.

The Anker Power Bank is designed to comply with USB-IF standards, ensuring compatibility with most devices. Charging via USB relies on the power delivery specifications of the connected port and cable. For example, Anker's 10,000mAh PowerCore+ Bank supports up to 18W PD charging, which requires a compatible adapter to achieve maximum speed. Data from Anker's official specifications shows that using a 5V/3A USB-A port typically charges the power bank at 1-2A, depending on the source's output capability. A 2021 study by the USB-IF found that 78% of USB-C ports on modern laptops and phones deliver 20W or higher, enabling faster charging for compatible power banks. Anker's engineering team emphasizes using certified cables to maintain efficiency, as unverified cables may limit current flow. Additionally, the power bank's built-in smart circuitry adjusts voltage and current to match the input source, preventing damage. Users should avoid charging the power bank in environments below 32°F (0°C) or above 104°F (40°C), as extreme temperatures reduce charging efficiency. Following these guidelines ensures safe and efficient power bank operation.
