    Quality product – could use an enhancement. Received and tested – works as expected after a brief setup. Enhancement suggestion: Since I have this as an emergency backup, there are two things that would be great: 1) A quick disconnect between the battery and generator – I measured a few milliamp drain while off and connected to the battery. Over a few months this might drain the battery. 2) Considering the drain, I put in my own quick disconnect that has connectors that mate with the Black & Decker trickle charger ($20) so while in storage I can A) Disconnect the battery and B) Trickle charge it from the B&D charger, Conclusion: Works great – would be good to have the “in storage” battery trickle charge option.

    Great Fit For an Rv with 30 amp Service. Bought to use with my camper that needs a 120 volt 30 amp service. It also needed to be an inverter to run electronics. The specs of this generator fit the needs. Plus when it was sold to me, it included , the battery, wheel kit and warranty ( not extra cost). It also weights less than half , uses about a third the fuel of the other generator ( 9000 watt/ 240 volt) that I was using.. Plus when towing my camper am noticing the weight difference, as I am planning a trip of around 7000 miles soon. ( Helps with cost of fuel ).

  3. Great product. Cranks every time and runs perfect I couldn’t ask for a better machine to power my travel trailer

  4. Bottom Line says:

    Using for RV and back up at house. Starts and runs great! Going to buy a second one to use in parallel.

  5. Did buy again. Had the 100302 for 2 years liked it but needed electric start so bought 100573 basically same generator with electric and remote start.We use it for 30 amp camper when we loose power crank it up and move into camper.

    Love my generator. I struggled for months trying to find just the right generator for me. As a solo female traveler, I was most concerned about weight of the product. When I realized I can simply build a ramp to get it in & out of the truck with ease. I then began focusing on reading reviews and ease of operation. This unit was super easy to set up from attaching g the battery cables, to putting oil in, and fuel. It came with the wheel kit which I haven’t put on yet, but it looks pretty straightforward. The unit is quiet, started up using remote on 2nd try and after reading the manual it looks like it will be super easy to maintain. The only one inconsistency I found is that in the manual it says to use unleaded fuel 87 octane or higher, I was always told to use clear gas in maybe that was just a personal choice from the person that taught me that? Not sure.

  7. Starts up on the first pull. It started up immediately. Love the weight. Reasonably quiet, I don’t think it’s irritating to have on. I put a aftermarket hour meter to keep an eye on the maintenance and I’m looking forward to seeing how long it will run on a tank of gas. Great product for us.

    Free Shirt, liked color. Purchased for power outage, and travel trailer. Inspected unit, only had scrape marks under frame, dragged on a floor at factory, I was pleased how light it was when empty of gas.installed wheels and feet, No oil provided, filled with oil, no hour meter or covers on receptacles, no fuel gage, started on second pull, I wanted to perform recommended 5 hours break in, and noticed motor has a bad vibration while running, embarassingly loud for a residential area, an hour and a bit later i shut it off, changed the oil, oil was shiny of aluminum, design flaw is drained oil creeps into gaps between block and support, then later on it drips to floor, noticed a crack developing in front panel, and when it ran the crack got bigger, contact support as the shipping box states to do, waited, contact again, get a response, they were concerned with my failure, in fact spent 6 hours in chat and diagnosing, once you ever read ” I’ll talk to my supervisor ” pack it up return to the store. I was ghosted for 21 days, they never use a contact name but a message “We appreciate your patience and hope you have a great day!” I was hoping for a great product, . Short coming in engineering the ‘U’ shape frame is structured with the plastic control panel, with the oscillation in vibration of out of balanced motor which is breaking it. The tow handle rattles something fierce. Liked the color!

  9. Great value, love it! Purchased for camping and off grid projects. Set up was super easy, some assembly to add the wheels, fill with oil (included) and gas (not included). Started with 2 pulls, nice and quiet! Quality machine, Looking forward to many years of trouble free service!
