Sometimes, you need an alternate method of powering household appliances and power tools, as well as your electric necessities when you are out camping. Generators are great devices to help you do just that, and units that run on propane are an affordable option.
Emission compliance and safety
This type of generators uses liquid propane; burning propane is safer than burning gas since it emits up to 40% less carbon monoxide. Moreover, propane does not have an expiry date, which means it can be stored indefinitely without going bad. You can also choose a hybrid generator that is fueled with both propane and gasoline for more power, but note that not all brands come with a propane tank included in the price. You can read on some of these generators that they are CARB compliant, but check the fine print to make sure this holds true in your state as well. Furthermore, the unit should be EPA approved to make sure its engine emissions of chemicals are not above the environment safe limit.
Some of the technical safety features these generators have included are circuit protection, automatic low oil shut off, as well as a fuel safety valve.
Horsepower and decibels
According to http://www.houseofgenerators.org/, Propane generators can have an electric start and a manual switch over, and an output of 4,000W to 10,000W. Useful units have several outlets, including at least one 120V AC and one 12V DC, and some models are portable to make them more convenient. Most propane generators are fairly quiet at about 70 dB, even though there are models that run in the 50 dB range as well.
These generators can run for ten hours at a 50% load, so they are truly energy efficient. If you know what to look for, you can even find much smaller models, with a 20 lb propane tank, that can run continuously for up to nine hours.
