Heater Bag, Hand Warmer, and Hot Water Heating Pad are all rechargeable and 220V. An inventive method of pain management is an electric hot bag. It is composed of neoprene and filled with an unique gel, unlike the conventional hot water bag, for maximum compression and heat retention. Its system is shockproof, and its fibers don't leak. It includes a rectangular, multicolored, printed pouch or bag containing the gel as well as a charging cord wire. Its dimensions are 24.5 cm x 6 cm x 16 cm, and it weighs around 1.3 kg. This makes it more convenient to use and carry at any moment. The pouch is durable since it includes a charging mechanism similar to that found in mobile devices.
