Comparison Bohmann BH-4120 1.2 L vs Zojirushi SJ-SD12 1.2 L

The main property of a thermos is to maintain the temperature of the liquid poured into it. Accordingly, the key parameter of efficiency is not so much the case material or some of its heat-insulating marketing chips, but the value of the water temperature after a certain period of time. So manufacturers, confident in the quality of their products, are happy to share their achievements. The temperature value after 6 hours shows how many degrees the boiling water poured into the thermos (98 °C) will cool down at an ambient temperature of about 20 °. And values of more than 80 ° can be considered very worthy.

So manufacturers, confident in the quality of their products, are happy to share their achievements. The temperature value after 24 hours shows how many degrees the boiling water poured into the thermos will cool (98 °C) at an ambient temperature of about 20 °. And with values of more than 50 °, a thermos can be considered one that keeps the temperature for a long time.

The presence of a cover in the scope of delivery of a thermos. The cover performs two main functions: it protects the case from dirt and scratches, and also slightly improves thermal insulation. In addition, additional equipment — handles, straps, etc. — in some models is placed on the cover.

Note that the case can be bought separately or even made by yourself, but it is most convenient to purchase a thermos immediately equipped with a case.
