Whatever the specs say, this unit DOES have a standard mini propane connector so you can use a Coleman-type 1-LB cannister OR an adapter hose to connect to a  standard tank.  And the grill cooks GREAT!  It sears the meat without over cooking and easily burns off the residue after you're done.  I woulda gave it a 4 but I added 1 for this - it COOLS off in 15 minutes after killing the gas so you can put it way quick.  For that I gave it a FIVE!
