Last Updated: 2026/04/23, Insulation cups are very common in our lives, but the insulation effect is uneven, and wired electric cups are too troublesome. They never manage to keep drinks at a consistent temperature for a long time. The magic of this nano electric cup is that it can be recharged by USB and can keep the drink at the ideal temperature for 45 minutes, if you pour a cup of heat.

Insulation cups are very common in our lives, but the insulation effect is uneven, and wired electric cups are too troublesome. They never manage to keep drinks at a consistent temperature for a long time.

The magic of this nano electric cup is that it can be recharged by USB and can keep the drink at the ideal temperature for 45 minutes. If you pour a cup of hot coffee, the temperature will be the same after 45 minutes.

Nanotechnology means that there are no more wires tied to the heating source. You just need to use the attached USB cable in your house, your car, and even collect your nanowires on your computer.
