Viomi Stainless Vacuum Cup 1500 1.5 L (SUS316)

Long-term temperature retention

The portable and ergonomic Vioomi Stainless Vacuum Cup 1500 thermos jug is made by Viomi, a partner of the well-known Chinese manufacturer, as the logo on the outside of the case eloquently speaks of. Despite its "childhood" age, the brand has an excellent reputation in its homeland, thanks to the innovative approach to its products for the Xiaomi ecosystem, which use more than 900 patent solutions. The vessel holds 1.5 liters of liquid and is able to effectively maintain the temperature of the drink for a long time. Water (boiling water) heated to 100 °C cools down to 54 °C in 24 hours, and an ice drink cooled to almost 0 °C heats up to only 5 °C in a day. These are excellent characteristics for a vacuum thermos. The model features an elegant SUS 304 stainless steel case, which has received a multi-layer coating applied by electrostatic spraying. The thermos has the shape of a jug with a characteristic spout and a protruding carrying handle.

Excellent thermal insulation of the flask

The ability of the flask to keep the temperature of drinks for a long time is due to the verified design of the walls, which minimizes heat losses. The outer layer of the flask is made of polished copper, in the middle there is a layer of vacuum thermal insulation, and the inner part of the vessel consists of an alloyed heat-resistant stainless steel SUS 316. This solution minimizes heat loss, and the metal walls of the vessel are more practical than a traditional glass flask. The lid with a thread and seals made of food-grade silicone hermetically closes a rather wide mouth, which is easy to fill with a drink. The lid has a protruding lever-button, which, when pressed, opens the internal valve. Therefore, to fill the cup with tea or coffee, you do not need to remove the lid at all — just keep the button pressed and you can pour your favorite drink from the spout. Unfortunately, due to the nature of the lid, it does not come with a cap-cup. Despite the abundance of metal, the own weight of the thermos is only 740 g. The model is available in white and black, and given the large capacity of the flask, it is quite inexpensive.
