Electric Hand Warmer
This is a very clever invention. I used to always use the disposable hand warmers but those only work once and you have to keep buying new ones. This hand warmer is small and portable and really heats up well. After 10 minutes, the hand warmer is burning hot to keep your hand warm in the coldest of weather. Also the device doubles as a portable charger which is great for the winter days when my phone dies, I can charge my phone while keeping my hands warm. When the cold season starts, I am basically taking this this EVERYWHERE!
