I only have an USB heater pad for my morning coffee. But it seems the USB beverage cooler bag is more suitable the upcoming summer.
The USB beverage cooler bag is constructed from nylon, carbon fiber and SBR materials. It measures 67 x 67 x 100 mm, and can easily accommodate your can of Coca Cola or other beverage. The cooler bag uses semiconductor technology to cool beverages. They say that just about five minutes, the temperature of the interior of the cooler bag can decrease to -10 degrees. Then a can of cold Coca Cola wouldn’t be difficult for the cooler bag. Moreover, the bag comes with a 1.5m USB cable.
This USB beverage cooler bag is available in three colors, including pink, black and camouflage. Each one costs $8.69 USD. If needed, you can find it at Uxsight.
