If your product no longer works properly because of how you used it. For example, if you leave your power station in the cabinet for too long, causing it to discharge too deeply. Or when you bend a semi-flexible solar panel too far, causing the cells in the panel to malfunction. A repair specialist will examine your product to determine how the defect occurred and whether the repair is covered by the manufacturer's warranty. If you want to have user damage repaired, when possible, you have to pay for this.
