It really depends on the cooker. Most of the electronic cookers only go up to 11 psi. I have 3 pressure cookers:
a 14 quart Presto designed for canning that allows you to select 5, 10 or 15 psi
an 8 quart pressure fryer that uses 11 psi (I can SAFELY pressure fry chicken that comes out like KFC Original Recipe)
a 5 quart electronic cooker that uses 11 psi (also doubles as a slow cooker and steamer/rice cooker)
ETA - before you think I'm crazy for having so many, the first 2 only cost $5 each at garage sales, and they are the only pots I have in those sizes.
