Convenient but powerful!

Worth every penny. Just two days after this arrived, we had a wildfire not too far from our house and lost power for about 24 hours. I was able to set this right outside of the garage and run a cord from inside the house to keep our fridge and freezer running. It will also be very useful to keep our well running. The size is perfect and makes it easy to carry from one location to the next. I've only used gas so far, but that worked great!

Great inverter!!

Great unit! Being able to switch gas input is amazing when needed, and it's very quiet for its size. You can absolutely get a stronger generator for cheaper, but with the capabilities and features this has, it's completely the better choice!
