This is a propane generator. Better than a gasoline generator, as electricity is the very thing you and gas stations will not have in a power outage. When you need more propane, go to your big box store and switch out the tanks. This one comes with an extra, full tank. The propane in the tanks lasts for decades and is safer near your home than gas cans.
Purchased new for $700 in 2013 (have receipt and manual). Run for a total of about 15 hours during two separate power outages in Ithaca. It kept the lights on and saved hundreds of dollars in replacement food costs held by two refrigerators and a freezer.
The starting sequence is detailed near the pull cord: very handy during a snowstorm. Note: one photo shows the grounding wire set up.
