Quiet and Lightweight 4800-Watt RV-Ready Portable Inverter Generator with Fuel Shut Off (56477i)

Very happy with this purchase for my older mother who uses an oxygen generator. With hurricane season followed by ice storm season, I needed something that I knew would keep my mom's oxygen going, was easy to start and maintain, dual-fuel and simple to operate so her (female) caregivers could get it running quickly and easily. This Wen 4800W inverter is perfect. Very simple to set up and run - quiet enough that you can barely hear it on the back patio. We're only using propane but it has plenty of power/watts so that even with the lower propane-fueled output I know we can run everything essential for my mom - even a space heater and the fridge if needed. Long extension handle makes it easy for caregivers and sisters to wheel around while not too heavy for me to lift (6'1" 195lb in decent shape).

I've only had this generator for a week now, but I wanted to report on my experience so far. I bought this unit to run my furnace in case of a power outage, but I wanted a unit that was capable of being connected to my house power panel should I decide to do so. I selected this generator because it has the most features for an excellent price: something I can lift (I'm 76), dual fuel, CO protection, quiet, etc. The only feature it does not have is an automatic switch over between fuel sources when one runs out (it appears on other models but not this one). So far, I have only done the 8 hr break in period, running with a low low1000 watt load and replacing the oil. (Do get the magnetic oil dip stick. It should come standard. There was quite a bit of metallic shards on the dip stick after the break in period.) I used only propane which is how I intend to use the generator unless circumstances require using gasoline. I got the 8 hours with just 10 lbs of propane so a couple of 20 lb tanks should serve for most power outages. Running just with propane has a number of advantages: only minutes to connect and start, longer run times between refueling, no concerns about gas degrading in storage or in the engine, and much easier on the engine, extending its service life. I would also point out that I tested the exhaust and was unable to detect any carbon monoxide. Of course, one should always run the unit outside as instructed but clearly running with propane is safer. So far, the unit has run flawlessly. One thing that greatly impressed me was how quiet it runs. What prompted me to write this review is an important feature missing from the manual and all videos reviewing this unit. Every video and the unit's manual say that you must remove the oil fill plug and tilt the unit to drain out the oil. Yet, just below the fill hole is a bolt with a rubber trough below it that is clearly intended to convey liquid. In addition, there is a hole in the case directly in front of this bolt that is clearly there to allow one to insert a socket to remove the bolt. I did remove the bolt, and it is clearly an oil drain plug. Using this method of draining the oil is easier and much less messy and avoids the danger associated with trying to tilt a 60+ lb machine. I am considering replacing this drain plug with a short length of pipe and cap that will make draining the oil that much easier. My next step will be to test out running my furnace off the generator using my modified power supply switches and electrical plugs on the furnace. So far, I could not be happier with this generator.

This generator has been a great purchase for my home. It provides reliable backup power during outages and runs smoothly without issues. The setup was simple, and the instructions were clear. I was impressed by how quickly it starts up and how much power it delivers — it easily handles my fridge, lights, and a few other essentials. It’s also not as loud as I expected, which is a big plus. The fuel efficiency is good, and the build feels durable and long-lasting.

Works like a champ! I got this after many years of losing power due to winter storms. I just need something to power the lights, the refrigerator, and the water pump for the instant-on all-house hot water. This is likely overkill, but there's enough extra if I want to add something else to the mix. I received this a few days ago but couldn't set it up until today. After I read the entire manual, I got the unit prepared: I filled the oil tank appropriately, connected the battery, set up the LPG connection, made sure the ECONO MODE was off, and then set the 4-function switch to CHOKE. One press of the START button and the unit began to start, but then stopped after a few seconds. I tried to think through why, and then realized that once the unit starts you need to set the 4-function switch to RUN. So I did that, and it began running immediately. I then put a device (a lamp) on the power outlets, and the unit ran well for the test. You have to take the access panel off one side to fill the oil, but it was easy enough with the included screwdriver, and you have to take the other access panel off to connect the battery, but again, easy enough. The screw/bolts that attach the side panels do not come out of the panel itself, so that means you won't lose one when you're trying to do all this in the dark! :) The included funnel makes it easy to fill the tank, but it's a bit tricky to see if there's enough oil. The included dip stick might not show the oil easily, but if you wipe off the dip stick before you put it in, then the oil level will show better on the stick, and if you lay the stick flat against a paper towel, you'll see the level of oil easily by the oil stain. I bought the recommended optional magnetic oil dip stick replacement. It is designed to remove any metal bits that might be in the engine post-production or that wears off from the engine action. Note that the length of the magnetic "stick" is slightly shorter than the included plastic one, so use the plastic one to check the true oil level. Connecting the battery is not difficult, but it's a bit tricky with the length of wire connecting the battery plug ends - not quite enough to get them both out to easily push them together. Pulling them apart is a bit tricky as well, because they are quite snug. Re-attaching the access panel for the oil fill opening was relatively easy. Re-attaching the access panel for the battery connections was more difficult - you really have to get both plugs back into the slot where they ju-u-u-u-u-u-st fit; without getting them in correctly, you can't close the access panel. I give a half star off for this. Not a terrible thing, but a design that could have used a bit more consumer testing and feedback. Turning off the generator is easy enough. You remove any devices connected to it, turn off the LPG, and then let it run until the LPG still in the system runs out. Then you turn the 4-function switch to OFF. After that I removed the LPG hose from the inlet plug in the generator, used the handle to roll the generator to the storage spot in the garage, and I was done. It is very easy to move because of the double retractable handle, much like the retractable handle on your luggage. It appears to be well made, with no visible defects in products such as plastic overspill on the formed pieces or bent or misapplied paint on the metal parts. The wheels are large and roll smoothly. The power output for this device is enough to run several ordinary appliances such as one refrigerator and one microwave, some lights, and for me, enough to run the on-demand gas-fired water heater. I bought the cover for the generator and a grounding device. They are stored in the box next to the generator itself along with the instructions. And I saved the PDF from the website in case I lose the instruction booklet! I've attached a video to show noise output, and some photos of the generator itself. The side panel access for the battery connectors is ready to get to, but it's wild to get the battery connector covers replaced and then get the connectors and wires into the *tiny* place they offer. It's nice and compact, and sits in my garage in an out-of-the-way place. 4.5 stars, with one-half star off for a poor placement of the battery connections which made it difficult to put the battery connection access panel back on the device.
