Winter will never be a good friend of our hot beverage. They will get cold very fast and leaving a cold damn drink to add the chill to our lung.
Although there is some gadgets that will help you add up some heat to your beverage such as cup warmer or the USB heated stirrer, it still pretty not eco-friendly since you need to use more energy to produce the heat.
The simplest solution is to get a thermos to store your drinks. Yep, thermos might be an old school technology, but that’s the best way to store hot drinks without the hassle to heat it up regularly using USB port.
This is a product from Thermos Japan. It comes with a cool sleek and shiny stainless steel body that can hold up to 280 cc or 9.5 oz beverage of your choice. The mug dimension is 11.5 x 8.5 x 12 cm and have a special design “flip cap” to drinking hot beverage as easy as a flip of cap.
