So, I received my 16000mAh Xiaomi power bank from
http://www.gearbest.com/mobile-power-bank/pp_144271.html
It came with all packaging, and looking at the power bank itself, it passes all the tests of being genuine (build quality, LED lights, white mini USB port, etc).
However, the box was a little squashed and when I tried to scratch the authentication label to reveal the code, some of the numbers scratched off.
If you're up for a little game, please help me figure out what the code is :)

Here's what I'm seeing.

X is anyone's guess.
