Appearance Inspection: A high-quality power bank's outer shell is generally made of high-quality materials and is finely crafted, with no obvious blemishes, scratches, or burrs. The outer shell should have a uniform color, and the buttons and other operating components should feel comfortable and be responsive.

Weight Assessment: If the actual weight of a power bank doesn't match its stated capacity-for example, a power bank labeled 10,000mAh is noticeably lighter than normal-it could indicate poor battery quality or inflated capacity. A 10,000mAh power bank typically weighs around 200-300 grams (this varies depending on the brand and design).

Charging Test: Connect the power bank to an electronic device and observe whether the charging process is stable. A good power bank should not overheat or experience interruptions during charging. If the power bank's surface temperature becomes excessively high during charging, or if the device experiences abnormalities during charging, such as an inaccurate battery level display or unstable charging speed, these could indicate a quality issue with the power bank.

Check the certification: Legitimate power banks typically carry relevant certifications, such as 3C. When purchasing, check for the corresponding certification mark, which is a key guarantee of quality. Certified power banks have undergone rigorous safety testing and meet national standards.
