Safety and Application
This power bank is specially designed for Zone 2 hazardous
environments including petroleum and petrochemical plants, natural
gas facilities, chemical plants, coal mining, grain processing,
woodworking, and firefighting rescue operations. It features
multiple safety protections: do not immerse in water, do not expose
to fire or high heat, use only approved chargers, do not
short-circuit, do not disassemble or modify. Stop using immediately
if unusual odor or excessive heat occurs. Keep out of reach of
children. For long-term storage maintain charge between 3.8V and
3.9V and store in a cool dry place. Dispose of according to local
environmental regulations.
