Larger for sure (does that make me #12) :-)
I did an occupational fire responder course with a group from work a few years ago and the instructor handed us "out of date" 2.5kg (5lb) extinguishers, similar to the little ones fitted as standard to caravans and motorhomes.
In the exercise, less than half of the extinguishers actually worked and the ones that did work farted out powder for <10 seconds... Barely adequate in putting out even a small fire. That scared the heck out of me!!!
I now roll with several super size extinguishers 6kg (13lb) at home & in the cars, and on camping trips.
I make sure to replace them every couple of years...
I've only ever had to use one of them in putting out a neighbours lawn tractor fire and the 6kg was more than adequate in putting out a fully engaged gasoline fire.
Getting some basic fire training probably was one of the best investments I've ever made.
