QuickCup lets you drink hot coffee within 3 seconds.

The kettle in the picture is not an ordinary one. Its full name is Tefal Quick Cup, or simply Tefal for short. The biggest feature of this kettle is that it can quickly heat cold water to just below boiling point, and this process only takes 3 seconds - yes, you heard right, just 3 seconds! Moreover, these 3 seconds are exactly the time it takes for the cold water to flow from the bottom of the kettle to the spout at the top. In other words, the water is heated while it flows. All you need to do is fill the kettle with tap water, press the red button, wait for 3 seconds, and then enjoy your coffee!

Of course, if you just want a drink of cold water, well, Tefal can also meet your needs. Press the black button, and clean cold water filtered through Tefal's unique filtration system will gush out. It's so refreshing that it might make you want to throw away your water dispenser.

Since the water is heated while flowing, the water at the bottom of the pot remains cold. This method of heating only what you need greatly saves on your electricity bill, reportedly reducing energy consumption by 65% compared to a regular kettle. Such a great product doesn't come cheap, priced at $120 each. But considering the long-term electricity bill savings, bite the bullet and get one.
