Chongqing police uncovered a large case involving the manufacture and sale of counterfeit and shoddy electric blankets involving a total amount of more than 20 million yuan. Counterfeit electric blankets have problems such as heating wires without safety protection wires, uneven heating, easy resistance short-circuit, controllers without over-temperature protection, and temperature control failure.

Semi-finished electric blankets are purchased from the Internet, and after assembly, labeling, and packaging, they are sold online at 30% off genuine electric blankets to all parts of the country.
