Using this heating pad is easy. First, find the wire leads and connect them to a 5V DC power source. In just a few minutes, the pad will start to warm up. You can place it in your hand for warmth or use it in heated clothing. When using, make sure the power source is stable and within the 5V DC range. Don't over - bend the pad as it may damage the internal conductive fibers. To maintain the pad, keep it dry and clean. If it gets dirty, you can gently wipe it with a soft, dry cloth. Avoid submerging it in water or using harsh chemicals. Also, store it in a cool and dry place when not in use.
