Customer Questions & Answers

Does this model have an electric start?

Asked by: Traveler
Thank you for asking, Traveler. The recoil starter is pulled to start this portable generator. Thank you for taking an interest in the Black Max line! I hope this helps! –Keri

Does it have a low oil auto shut off?

How many outlets?

The pictures and product description say that it has (4) 20amp GFCI outlets + 30amp 240V outlet. However the product details say it only has 3 outlets, (2) 20amp non-GFCI outlets + 30amp 240 outlet. Big difference, so please let me know what it accurate, as I'm comparing it to another model and this will be the deciding factor.
Asked by: Bobby
Thank you for asking, Bobby. The following single phase, 60 Hz outlets on the control panel can be used for operating appropriate equipment, electrical lighting, tools, and motor loads: two 120 Volt AC duplex GFCI 20 Amp receptacles and one 240 Volt AC, 30 Amp receptacle. I hope this helps and we appreciate your interest in Ridgid! -Keri

6,500-Watt 420cc Gasoline Powered Portable Generator is rated 4.7 out of 5 by 30.
Rated 5 out of 5 by from Outstanding Deal At the current deal price, good luck find anything anywhere near this good anywhere near this price. I had been hunting a deal on an electronics friendly portable generator for a long while. Nothing can touch this deal. 6500/8125W, THD 6% or less, long run time, all for about $550? The comparable (THD 6% or less) Generac XP6500E sells for nearly $2k. First assembly: Wheels and feet are super easy to attach. Fill with 1 qt of included oil and you are pretty much read to go. That's it. Its really easy and takes only about 20 minutes. Generator: This is a 6500/8125W unit rated for continuous duty as stamped on the generator nameplate. The engine may not be rated for continuous duty, but the generator portion is rated for this. I would say this is the minimum size generator if you plan on using a 30A transfer switch. It can provide 27.1A at 240V, 54.2A at 120V. Note, this is a little less than 30A at 240V. Therefore, you will have to be careful not to overload the generator if you intend to use the 30A service. It will be possible to not trip the units main breaker and be overloading the generator with this one connection. IMO, this issue is lessoned by the fact that you do have a power display that seams to be fairly accurate and can help you determine what is too much. Ideally, though, you would be better served with a 7500W unit if you plan on a 30A service. For this price, however, it will work for me. There is also a convenient ground lug right on the generator housing. My unit puts out acceptable voltage and hz, as you can see in the pictures. That was with a 1500W simple resistive load. Engine: The box did include 1 qt of 10W30 oil. Another poster said it doesn't bring that, but mine did. It did appear as if oil had been in the crankcase already, and I assume this was for factory testing. Anyway, the crankcase takes 1 qt oil to fill, so this was perfect. Added the oil and about 1 gallon of treated fuel. The unit started right up on first pull. Amazing! I have never had any small engine anything that started on first pull out the box. I then ran it for about 30 minutes, and the unit worked flawlessly. Yes, it is loud. None of the generators I have ever owned have been quiet and this unit is on par with all the others. Note, go ahead and buy another 2-3 qts of oil with this. First change is after 1 month or 20 hours. That will come fairly quick. After that, its 6 months or 100 hours. Remember to crank this up every month and run for at least 15-20 minutes. Also, shutdown by killing the fuel flow. You don't want fuel to remain in the carb if possible. Obviously, ALWAYS use a fuel stabilizer. I prefer Marine Stabil. There is no electric start, but, honestly, that is not a big deal. Those batteries usually die within a year or two, and the units themselves don't charge them. It ends up being kind of a pain on these smaller generators. Practical use: Again, I believe this is pretty much the smallest generator to be used with a 30A service connection (such as a 30A transfer switch). It can deliver 27.1 continuous or 33.9A surge. This would be enough for a fridge, a chest freezer, most of your lights, 2-3 ceiling fans, router, cable modem, DVR, 2-3 modern TVs (60 inch or less), a desktop computer, charge all your tablets and phones, and a 12000btu portable AC. In addition, you should also be able to run a toaster or toaster oven or coffee maker or microwave or similar small appliance, however, only one a time. If you need to run the water heater, you could pull that off as well, but you will have to turn off most everything else while you do it. This is ok for a tank heater, as you only need to run that for about 60-90 minutes for all day hot water. I would not recommend a thankless water heater be used with this generator/30A service. If you have a smaller central AC, say 2.5 ton or less, and it is 16+ SEER, and you have a soft start kit, maybe, just maybe, you can run with this generator and a 30A service. However, that's about all you will be able to run if you can in the first place. If you plan on powering a small-mid central AC, you are much better off with at least a 10kW+ unit and a 50A service. Still, you will likely need a soft starter kit and it will have to be high SEER. Runtime: Compared to units that can be used with 50A service, keep in mind that fuel ends up being the problem. This unit can be run 24 hours a day while powering at least all the important stuff and likely only go through about 16-20 gallons of fuel. That's a lot of fuel, but its manageable. With the unit full plus 50 gallons of cans, you should be able to squeeze out 3-4 days of 24 hour operation or 5-6 days 16-18 hour a day operation. 7-8 days if you are cautious. That should get you through most outages, or at least long enough for the gas stations other services to open up again, roads cleared, etc. The larger 10kW+ units usually use about twice as much fuel. So, to get this same runtime, you would need twice as much fuel stored in your garage. 50 gallons is a lot, but 100 gallons is ridiculous. Not to mention the cost of the fuel. Spending $250+ for 100 gallons of recreational fuel (and I wouldn't run anything else) to run 24 hours for 3-4 days is absurd. Also, after storm gas sales are usually limited. It is unlikely they will even let you buy 100 gallons at a time in this first few days after they re-open. In storms past, I remember it being more like a 20 gallon limit. So, you either store more to begin with, or get ready to travel to the next town to get your fuel. Forget all that. I would rather live with less. Final thought: This is a fantastic buy for a 30A service suitable portable generator that is electronics friendly and has great runtime. You will be able to run all the important stuff in your house, plus a small portable or window AC. If you stage your usage, you can even heat your water, run coffee makers, etc. Probably not gonna work for even smaller central AC's, but running this thing through an outage will greatly lesson the hurt and not break the bank with fuel consumption. For this price, you really cant go wrong. Contractors/jobsite: I would not recommend this for the jobsite. While the wheels and feet are good enough for residential use, they are not likely going to hold up to day-to-day abuse of a jobsite. Also, the unit is rather heavy at roughly 250lbs. Loading in and out of a truck takes two very strong people, and will get old fast. You would be much better off with your 4000-5000W units without wheel kits that come in a 150lbs.

Rated 5 out of 5 by from RIDGID Gasoline Portable Generator 6500 Watt Model RD906500P with a 420 cc gas engine, this Portable Generator is a great purchase. I live in Florida bought this generator on line at Home Depot and it was shipped directly to my home. After servicing it with oil and gas pulled it one time and started immediately. I ran this generator for three hours to give it a test run and it operated a 8000 BTU Window A/C unit, my refridigators and some lights. The whole purchase experience was flawless. It took them 7 days to deliver from Ga. and free delivery. If there is any unfavorable thing about this generator it's abit noisy but for the price it's a deal, now on sale for $551.85 in their on line catalog, even a better deal than I got.

Rated 5 out of 5 by from Good price for this size generator Unit purchased for backup use during power outages. Needed something large enough to power (2) refrigerators, (1) freezer, small portable a/c unit, fans, lights, etc. Unit started on the 2nd pull and ran smoothly with electrical loads applied for a 30-minute test run. Generator does NOT come with oil as needed prior to starting even though all of the literature, quick set-up guide and label attached to gas cap say to use the oil PROVIDED. NONE is provided. Our local Home Depot store gave us the quart of oil needed after showing them all of the paperwork for the generator.

Rated 5 out of 5 by from Soild and powerful This generator starts with first pull. and when doing things the safe way, like the ease of wiring this up to a transfer box to power your home. this generator has a ton of power for what you need and you will have a lot of wattage left over if you need it. it comes with 4 120 volt outlets on the panel.and a 220 output to power thing like your home....I ran all of my flood lights, in living room and kitchen, refrigerator, ceiling fans, 54 inch TV, satellite, kitchen and living room outlets, and a 1500 watt heater in my master bath. and hit around 2600 watts. And still had 3900 more Watts left over, if needed. run your house with this and in conjunction with your propane insert, if you have one. and you surely have it made in an outage. Ridged I hear is a solid product and I guess I bought this out of season, generators like this usually run 800--900 dollars or higher.....I would buy this if its in stock...I got free shipping right to the store...also, after you assemble the wheels onto the unit, it is very easy to move o were its safe to run and were you want it.....glad I bought this....just remember to run it once a month and keep gas treatment in you fuel cans that fuel it...and you'll be ready for the next power outage for sure!

Rated 5 out of 5 by from A GREAT INVESTMEMNT This generator is a good investment for now and the future. I picked it up from Home Depot and read the instructions and I was ready to test it. I pulled the cord one slow time and it started right up and ran for a good thirty minutes while I plug in all types of equipment. I make it a point to start it every three week to keep everything working good. I have always liked and purchase RIGGID equipment.

I bought it as Hurricane Matthew was coming close to Florida. It was easy to setup and started on the first pull. It had plenty of power, and never hiccuped as new items were added or as the refrigerator compressor kicked in. It seemed to be very fuel efficient since I was only using about 1/6 of its advertised generating capability. It is heavy. When setting it up, two people would make it easier - but one could do it in a pinch. The frame is sturdy and makes moving the unit pretty easy. The engine, although loud, seems well built and easily up to the task. I am really happy I was able to get this generator and it was delivered earlier than expected.

Rated 5 out of 5 by from so far so good I live in the NW and bought this in case the big one hits (since I now have a generator, nothing will happen) It will be used to run electronics, well pump, frig and freezer Assembly was easy, wheels and handle add oil and fuel. The unit moves ok over a gravel driveway, bigger wheels would have helped. But not necessary. I tested the unit on our electronics and everything worked fine. The only concern I had with the product was a nut laying in the bottom of the bag the unit came in and I cant find what it goes to.
