    Good news for coffee and tea drinkers: No more wasting time and energy waiting for the perfect cup. Using patented Heatworks’ Ohmic Array Technology, the DUO Smart Untethered Carafe (玻璃水瓶) has the power to heat or cool water to the exact degree while you pour. With its functionality, convenience and stylish appearance, the DUO looks like quite the game changer.

So how does it work? The precise temperature control lets you pick the water temperature to the plus/minus one degree. Simply set your temperature, pour water into the tank(fits four cups) at the top and pour into your cup. The carafe features one blue spout(出水口) for filtered (过滤的) cold water and another red spout for hot water, which appears to heat up instantly.

The entire device is battery operated, making it perfect for taking it to the office or really anywhere else. Youwill also be able to plug it in, so the carafe can stay comfortably on your kitchen  table or desk to charge for on -the -go use.

The DUO advocate 99 percent energy efficiently and an advanced water filtration system created by heat works CEO Jerry Callahan,who wanted to create a heating system without using metal heating elements. Unsustainable and imperfect metal heating parts have been used for heating for the past 100 years and carry the risk of rusting(生锈). Callahan felt It was time for an upgrade heating systems, and the Ohmic Array Technology was born. Using electrical currents passed through the water itself rather than separate heated elements to transfer heat into the water. Ohmic Array cuts out a whole step in the process.
