    • This generator works great for me
Color: Dark Grey
I bought this generator to use on a five day camping trip because my old one died. It ran almost non-stop for those five days and worked great. It ran my fridge, TV, and battery charger just fine. So far so good.

    • This works really great and starts up every time
Color: Bright Red & Black
I've been really happy with this generator. It runs pretty much everything other than my large air conditioner in my RV. And I didn't expect it to work with the air conditioner because it pulls a lot of current. It's so much easier to travel with than the larger generators I've used in the past. I highly recommend it it if you need to run items, 2500 watts or less ... show more

    • It runs well smoothly, but not enough wattage
Color: Dark Grey
Yes, it does and I really needed one with more wattage. I can't run the my 3 compartment burner and fryer at the same time. I have to use one or the other and this could cause serious health violation and I have to tried and buy something bigger, asap and it was $450.00, on this item, and I really could use to purchase another one. I even researched to see if this was the wattage I needed and all researched unsure me it was. ... show more

    • Great Generator 👍 love this little guy
Color: Dark Grey
Make sure you put the cap on or off. Depending when using it. I learned the hard way. Make sure to brake in for an hour then change oil. Great generator for my detailing business. Gasoline efficient. Helpful when needed. Easy start quiet under 2000 watts or on eco mode.
