Have been getting by with one of these for about 3 or 4 years now.
What's handy is the 12-volt power supply that is built in.(it's 110ac and 12-volts dc both) If you have to charge boat batteries and need a light bulb or maybe some xmas lights this is the ticket. Runs a long time on a gallon. Not all night but close enough. Have used it to run a little space heater in the tent too. The electric blanket is priceless when it's icy cold.
Someday I will upgrade to something with balls but til then it'll have to do. https://www.farmandfleet.com/products/8 ... rator.html
