Usage recommendations

For longest battery lifetime, avoid extreme temperatures during use and storage, and charge the power bank periodically if not used for extended periods. When charging high-power devices such as laptops, ensure total connected load does not repeatedly exceed the maximum rated output. Use appropriate PD-certified cables for USB-C fast charging and follow device manufacturer guidance for best charging practices.
