Love this little generator, it quiet, and powerful, I have an older model GM 3500 which doesn’t have the on off switch or a battery charger input or the 12 V cigarette lighter plug, but this GM 5000 has all that so I don’t have to worry about it starting on its own while it’s packed in the back of my truck. Because it has the on/off switch to prevent that, and if my battery gets low, I can just plug in the charger on the front and it will charge the battery and having a 12 V cigarette lighter plug on. It means I can plug in my portable fridge if I need to.
