What models of stove utilize bottled propane that you by from your local store? Is the bottle propane considered high or low pressure?

Answer:   Two bottles are popular in the market, 20lbs and 1lbs.  20lbs one is used for BBQ, back yard cooking, tailgating etc.  1lbs is mainly used for camping (light weight).  All our stoves can work with the 20lbs propane tank (bottle).  Our configurable stoves can work with both.  Gas coming out direct from bottle is high pressure.
