BILT HARD Generator 2500 Watt, Dual Fuel Quiet Inverter Generator with Electric Start, 120V NEMA 5-20R, NEMA TT-30R and 12V DC Output, 79cc Portable Outdoor Generators for Home Backup and RV Ready

Works great. Starts right up. Reasonably quiet. I’ve only run it on propane and have not had any issues at all. The only thing I don’t like about it is that you need to turn it on its side to change the oil. This is cumbersome and a little messy.

AS SOON AS DUAL FUEL GEN SETS CAME OUT I GOT RID OF THE GASOLINE DIRTY CARB UNITS, THIS 4500I IS A SUPER GEN FOR THE LOW PRICE , WE SELL GASOLINE VERSION AT WORK WITH A BRAND LABEL (SAME GEN) FOR 1300$ +TAX , WHEN I SAW THIS FOR 699 I HIT THE BUY NOW AND HAVE INTEREST FREE PAYMENTS FOR A YEAR ON MY PRIME CARD, CANT BEAT IT ANYWHERE , I RUN ONLY LP SO MY EMERGENCY GEN WILL RUN PERFECT NO MATTER HOW LONG ITS BEEN STORED, JUST REMEMBER ON LONG STORAGE GOOD IDEA TO PULL THE NEG OFF THE BATTERY . BEST DEAL OUT THERE PERIOD!

Item arrived with destroyed box but was undamaged. As others have stated oil capacity is wrong. Electric start works great and it's fairly quiet. DF works fine on both, but less power on propane. Despite supposedly 4500W won't run 1350w AC and 1000W microwave without going into overload. 12v outlet won't run air pump. Says under voltage.

Recommend: DO NOT BUY. Repeat: DO NOT BUY Problem: Oil Level Sensor circuit DISABLES electric start after several hours run time. Oil level: FULL. If you stop the the generator after running for several hours, the unit CANNOT be restarted with the electric start. That circuit becomes completely disabled. The only way to restart the generator is to remove side panel, set the choke, and then pull start. As you can see by pictures, I bought 2 of these generators to run RV AC 24/7 during Las Vegas summer. Highs are avg. 110 F. Lows are avg. 85 F. I use LPG only. Fuel consumption 0.45gal/hour. Both generators have the same problem. I discovered this issue shortly after purchasing the first generator. When I shut down to replace the LPG tank, the generator would not restart. Starter circuit remains disabled for hours and hours. Same issue with the 2nd generator. If you shut down and expect electric start then forget it. You must manually choke and pull start. I have 654 hours on generator 1. And 208 hours on generator 2. Built Hard Customer Service: All they do is say they will consult with their engineering and get back with you. They never offer any suggestions or solutions. I assume it is a offshore call center and there actually is no support available. They text only. Conclusion: The generators perform well when they are running. However, this model generator CANNOT be reliably restarted once it has been shut down. I believe the oil level sensor is faulty and causing the electric start circuit to temporarily fail. Note: both generators will restart normally if they have not run for 10-12 hours. Which is why I bought 2 generators. I run unit#1 for 12 hours and then shut it down. I then start unit #2 and run it for 12 hours. Each generator gets a 12 hour rest. Otherwise it's, remove side panel, set the choke, and then pull start - a big hassle and extremely frustrating.

Update after first real use.....so I took this out in the field on a 3 day hunting trip. Here's what I learned.....the run time on a full load, even in Eco is at best 7 hours a tank. I had it hooked up to a 26 ft RV running the A/C 24/7 basically. From Thursday evening thru Sunday morning we burned approx. 21 gallons of fuel. That's 21 gallons in roughly 64 hours so a little less than 1 gallon for 3 hours of run time. Granted we had it maxed out, but alot less run time than I anticipated. So let's talk about the max running wattage. We had the generator overload at a minimum of 5 times. Here's what we were powering, the RV A/C, lights, fridge, occasionally the water pump (that seemed to do it most often) an external shop lighting system, 2 floor fans and the RV fridge. I'm not sure what the total wattage was on all that, but at times it was more than the generator could handle. That said, it was very quiet. I ended up setting the generator on a small little shop step ladder to keep it off the ground, I just didnt want to put the intake that close to the ground. I'll do that going forward as well. It's a heavy little unit, but even with gas in it, I can lift it in and out of my truck. All in all I thought it did a good job. The e-start worked great and like I said it was quiet. The biggest downside was the unexpected fuel burn. Take lots of gas or propane if you're going out for several days. I started with 18 gallons and then had to jake a 55 mile round trip to the nearest town to get more gas. So I’ll preface this by saying I just got the generator so I don’t have a long term review as of yet. First off the packing was good and arrived very quickly. The instruction manual is good and an easy read. Nothing I saw about break in for the motor, but I think we all understand it’s a good idea to run it at idle for about an hour or so then change the oil and run it on a load and change the oil again and go (your procedure may vary). It’s a pretty simple generator, but you have to do a couple of small things first before you light it off, especially if you’re using the E-start (which I did). There are 4 brackets underneath the unit that I assume were there for shipping that need to be removed first thing. The enclosed tool kit (which was a pleasant surprise) has the 10mm wrench you can use to do that. It takes about 2 minutes. Then connect the battery to the lead. This compartment is on the front of the unit and requires a flat head screw driver to open the hatch (oddly enough the included tool kit didn’t have a flat head screwdriver in it, at least mine didn’t and that seemed like a silly oversight). Next the oil, the side hatch for that is opened with your fingers so no issue there. The oil dipstick filler cap is orange plastic. It lasted exactly 1 removal and the. Wouldn’t go back on due to bad threading. The threading on the filler cap is total crap, or at least mine was. Fortunately, I also purchased a metal magnetic filler cap at the same time so I just swapped it out right then and there. I highly recommend that small additional purchase. Besides, a magnetic filler cap will collect small pieces of metal the engine makes, especially a new engine when it’s breaking in. Ok so now we have the battery connected, oil in the crankcase and about 1/2 tank of gas in the unit. Turn off Eco mode, move the 3 in 1 dial past run to the start position and push the red lever like button thingy in on the dial. It coughed for a second then lit right off. It loped for a minute of two until the fuel was flowing steady then settled into a nice quiet hum. I’ve never had a quiet generator so to me it was truly remarkable how quiet it was. I mean it’s really quiet. Now granted Im accustomed to my 10000 watt generator/welder when it is running so you might have a different reaction to the noise level. Still, I was talking on the phone about 15 feet away from it and I really couldn’t even hear it. That was at idle, when I connected various tools to it to run it up I still couldn’t hear the generator over the tool that was running. It’s really that quiet. My only 2 knocks on the generator so far is the oil filler cap and the lack of covers for the electrical outlets. The latter I knew about of course when I purchased the unit, but still how hard would it be to add 3 plastic covers on during assembly? In order to protect the unit while not in use I also purchased a WEN generator cover (not expensive at all) and it fits like a glove. Oh, more more thing. The metal oil filler cap I used was really hot. I waited about 10 minutes after I shut it down to remove it and it was still hot so wear gloves or give it a little more time before removing it during break in. I’ll be taking it out in the field next week and it’ll be hooked up to a 30’ rv running everything including the A/ C so I’ll update with gas only run times and anything else that is notable. I’m sort of curious how the bottom air intake is going to handle being that close to the grass and dirt. That’s a potentially big negative if it starts sucking up all kinds of crud.
