⚖️ Seller Warranty & Marketplace Dispute Conciliation

Contact support under the seller's warranty and marketplace return policy if the Power Bank exhibits a manufacturing defect, such as failing to charge even after following all instructions, abnormal overheating during normal use, or if the LED indicators do not function correctly without any signs of misuse. These are cases of manufacturing defects that cannot be resolved by the consumer.
