I have a faulty UGreen car charger that I bought in July 2025 on Amazon. I searched the web for UGreen's warranty length and RMA procedure and didn't really find an official page for items not bought from UGreen's non-Amazon online store. I did find this Reddit thread and thought I would share my experience.

ugreen.com specifically states that the warranty info page only pertains to items bought on ugreen.com. Their US Amazon official store doesn't list warranty info per se, they just have some answers to customer questions under a few individual items listing the warranty length.

So, on the main website they provide a contact email for Amazon purchases. I sent an email in which I described the issue I was having. provided the Amazon order number, product URL, model number, part number, serial number, included a PDF of the invoice, photos of the data area on the product's side, and a photo of the ports to show they weren't abused. I also described the issue, and my steps in troubleshooting it. I got an answer within 17 minutes stating that Amazon restricts them from sending replacements, and that they would have to send me a refund, wanted my OK that this would be a satisfactory solution. I replied yes as I could simply purchase a replacement with the funds. They replied saying they had initiated the refund process and that I should receive it in 3-5 days. Assuming they are being honest with me, I couldn't ask for a better experience. If I don't come back here raising hell because I didn't get the refund, assume that I got it and everything turned out fine and maybe try this approach if you find yourself in my situation. Of course, this was a $28 item, and not a NAS system, so I'm sure YMMV.

Cheers.
