I bought these for a 2019 10" Fire tablet that has always had charging issues. They're not working on it. Waste of money as the sites say it will work. The tablet was returned due to charging issues and can only be used for a few months with the same cable, or longer if the cable is of a better quality, but it's finicky and I know it. So it's part tablet issue, part cable issue, but the cable just drains the charge instead of charging the device.
