Small power distribution cabinet fire extinguishing device, car battery fire protection, self-triggering fire extinguishing device, household small fire extinguisher

This is a nice, small form extinguisher that is great for use in an enclosed area like an engine bay or cabinet. I’m using it with my tool batteries and chargers inside a metal cabinet since they’ve been known to malfunction and catch fire every now and then. There’s no way to know if it really works unless there’s a fire but assuming it does, it’s a great design and a great option for inexpensive fire suppression where full blown industrial systems aren’t financially feasible.
