For best results, always use a MagSafe-compatible case — thick or heavy metal cases may reduce charging speed or weaken the magnetic connection. Do not expose the power bank to extreme heat, direct sunlight, or water as this may damage the battery. Never attempt to open, puncture, or modify the device. Keep out of reach of children under 12. Note that the magnetic attachment may interfere with the camera on certain Android phones such as Samsung Galaxy Z Fold models — iPhone 12 and newer is the recommended use. If the device becomes unusually hot, swollen, or starts making noise, stop using it immediately and contact our support team.
