Website to Check Validity of Xiaomi Powerbank 2C
I'm not sure if this is the best forum for this.
I have received two 20000mAh Xiaomi Mi Powerbank 2C units from an eBay seller, and while the one I have opened has the properties that suggests it's genuine (according to various websites), I have been unable to find a website that allows me to verify the 20-digit code found by scratching off the label on the box. All the links take me to a site (https://www.mi.com/verify/#/en/tab/imei) which is designed for phones and lets you enter an IMEI or serial number. When I enter the 20-digit number, I get the message: "Your IMEI or S/N doesn't exist, please verify and enter again".
I have sent a message to the seller but, while waiting for a reply, I was wondering whether anyone here has had this issue or knows of such a site.
