We do not know the logic behind this possibility.

Portable Intelligent Thermal Vacuum Water Bottle from xiaomi youpin - $ 29,99

On top of the osmosmos, which has a capacity of nearly half a liter, a power-saving OLED screen has been mounted, which, thanks to an internal sensor, can display the current temperature. There are other clues: the stuff counts the time since the last upload, plus a toy has been included, the rock-paper-scissors - don’t ask why.

The thermos no longer promises extra things in other respects, maybe even the screw cap can be interesting. It is good to know that according to the distributor, keeping warm can be up to 6 hours. The stuff is not too heavy anyway, despite the correct insulation, its weight is approx. 310 grams - presumably includes a button cell battery to power the display. 

The thermos is unfortunately only available in two colors: black and white. The design of the product is not bad, however, the practical leather strap does not seem to be objectionable either. Tea grass soak is also a good thing, so we can make our drink on the go.
