Using this heating pad is easy. First, make sure you have a 5V DC power source. Then connect the power source to the wire leads of the heating pad. In just a few minutes, you'll feel the pad start to warm up. It's great for keeping your hands warm or adding warmth to your clothes. When using it, don't cover the pad with thick materials that could block heat dissipation. Also, avoid bending the pad too harshly to prevent damage to the internal conductive fibers. To maintain it, keep the pad clean and dry. If it gets dirty, gently wipe it with a soft, dry cloth. Don't submerge it in water. Store it in a cool, dry place when not in use.
