The hand warmer is charged via USB and has a built-in battery with a capacity of 300–500 mAh. The device has two or three heat levels that you can adjust according to your needs. With two levels, you can choose between low and high heat, while the three-level variant also offers a medium setting. The hand warmer is available in various colors and is packaged in a gift box or color box. Some variants have magnetic attachments, allowing you to attach the warmer to metal surfaces.
