Spencer 2 in 1 Rechargeable Hand Warmer, 5000mAh Portable USB Electric Pocket Heating Warmer Power Bank for Raynauds, Heat Therapy, Outdoor Sports "Champagne gold"

Great way to keep your hands warm in winter if waiting for the bus or just being outdoors. I volunteer outdoors year round and in winter this really helps my hands stay warm, I keep it in my pocket. On the lowest setting it only lasts about 1 hour. Of course it is working against our bitter cold weather in Wisconsin. I also use it while just driving, until my car warms up. I just charge it every night.
