The Proove HeatBean is a set of two electric hand warmers designed in a unique coffee bean shape that allows them to snap together magnetically. These compact devices offer three adjustable heating modes at 40°C, 45°C, and 53°C, providing a customizable level of warmth depending on how cold your hands are. Crafted from aluminum in a brown finish, the warmers are powered by a 2500mAh battery that delivers up to 13 hours of use on a single charge. You can replenish the power via the USB Type-C port, which takes about 4 hours to reach a full charge at 10 W. Their ergonomic design and portable size make them a practical companion for anyone spending long periods outdoors in winter weather.
