VEVOR Countertop Ice Maker, 37lbs in 24Hrs, Auto Self-Cleaning Portable Ice Maker with Ice Scoop, Basket and Drainpipe, 2 Ways Water Refill Stainless Steel Ice Machine for Home Kitchen Office Party

A few hours in 70°F indoor temps. Ice melts back into machine and water is reused to make new ice. A full bucket of ice should last more than 2 hours but because it is nugget ice it melts faster than regular ice.

This depends on the room temperature. We cannot give a definite answer.

Thanks for your feedback.
