I've only bought this item once and that was about 10 days ago so it's difficult to rate its durability. I have no idea what purity means. It charges my phone perfectly. The only problem I have is that it protrudes a bit from the dashboard. I had one that fitted flush and liked it better. My son took this. I bought this because it claims to charge fast. Hope that helps.
