Contact support for warranty if the power bank exhibits manufacturing defects, such as not charging at all after basic troubleshooting, dangerously overheating during normal use, or if internal components appear loose or damaged without any signs of misuse. These are issues not resolvable by the consumer and are covered under the seller's warranty and marketplace return policy.
