Consequence: Can cause immediate damage to the charger's electronic components and, in some cases, to the battery or vehicle's electrical system.
✓ How to avoid: Always check and confirm correct connection: red clamp to the positive (+) terminal and black clamp to the negative (-) terminal. Note: Standard US wall outlets supply 120V. This 220V-240V appliance requires a dedicated 220V-240V outlet or a high-wattage step-up voltage converter to operate in the US.

⚖️ Seller Warranty & Marketplace Dispute Conciliation

Contact the seller for warranty service if the charger exhibits malfunctions not resolved by the self-help steps, such as failing to power on even after checking the outlet and fuse, excessive and dangerous overheating during normal use, or if the display shows no information despite being powered and correctly connected. These may indicate manufacturing defects or internal component issues.
