Xiaomi tease another accessory; Believed to be a Power Bank

It's now starting to be a routine for Xiaomi to tease one accessory after another. Not long ago, the company teased another device which later turned out to be a router.

This time round, we're shown an image of what looks like an aluminium-clad mobile power bank. The image was put up by none other than Xiaomi CEO Lei Jun on his personal Sina Weibo account. The device can be seen having a minimalistic design with the typical 'Mi' logo on the front.

Over to you guys now, what do you think it is? Hard disk? Power Bank? Or? Let us know what you think!
