Can salt packets be used while charging?

You can't use salt packs when charging. When charging, the current and voltage do not match, which will damage the battery in the salt bag and cause safety problems. Salt bag refers to a therapeutic bag made of mixed salt of traditional Chinese medicine or herbal medicine, which is mostly used to dispel wind and hot compress the affected area to relieve pain and other symptoms. Ensure safe use, and don't charge the salt packet at the same time to avoid potential danger.
