My only use for a small portable generator is to power-up the onboard SMART MODE CONVERTER/CHARGER unit of my OFF-ROAD POPUP trailer to re-charge my battery bank in a quick three hour generator run time.
The 1000WATT Honda is a bit to small wattage output for me to use. My 2KW Honda Generator revs up rather fast when I use it telling me it is even right on the edge of not being enough power.
There are a few other reasons to have a portable generator but in my case re-charging batteries in a three hour generator run time when camping off the power grid is my number one priority.
