Ankers warranty policy states:
Not Covered Under Warranty:
● Products without sufficient proof of purchase
● Lost or stolen products
● Items that have expired their warranty period
● Non quality-related issues (after 30 days of purchase)
● Free products
● Repairs through 3rd parties
● Damage from outside sources
● Damage from misuse of products (including, but not limited to: falls, extreme temperatures, water, operating devices improperly)
● Purchases from unauthorized resellers
With that said, you can email support and let them know and ask they make a 1 time exception to warranty the item for you. But know they are not obligated to as it is stated free items are not covered under warranty
