Mine is a plugin type but I told my wife we need one for ice storm duty when we might have something burninig in the house during a power outage.
Every hurricane in Fla there were deaths caused from BBq grills being used for cooking in the house.
Did you see all the deaths here during the ice storm from people burning charcoal in the fireplace or using a grill inside????? I nearly went crazy!!
I heard that that "chamber" they have in Charlotte that they use for the "bends" ran full time with people who were overcome with the fumes.
