Consumer Review XP8500E

I finally decided to 'pull the trigger' and get a generator. Living in Connecticut, having the power go out 5 times over the last two years and having no power for more than two days is no fun. When looking for a generator I researched a lot of them but wanted certain features. I found them all in the XP8500. Here we go: Shipping: This item shipped for FREE and thankfully - it weighs in at over 200 lbs. 225 to be exact. The item shipped via FedEx which was another blessing. FedEx freight called and delivered on time with the package in perfect condition. It took about a week to arrive after I placed my order. Perfect. MaxTool was great - communication was solid and they were very helpful with answering my shipping questions. Here is what I was looking for in a generator: Volt meter Gas gauge at least 8000W electric start with pull start back up 4 120v outlets a unit with a muffler auto idle Carb compliant engine at least 15HP Assembly: As I stated above this thing is heavy. Once the wheel kit is assembled it carts around nicely although the handles are short - I'll get into that later. So, here is what I did which made things easier if you don't have help. First, cut the box with a box cutter knife on the corners so the flaps fold down. Now, get three 2x4's each about three feet long and stack them. This will give you enough clearance to get both the feet attached as well as the wheels. Start with the end which will have the feet. Lift this end up and slide the stacked 2x4's underneath. attach the feet, two nuts each. Now, you have the footing on one side you can use the 2x4's on the other end where the wheels go. Same thing on this end with a twist. Attach the axle - two nuts and bolts each side. Now, lift the side up just a bit so you can slide the wheels on. Once they are slid on you can secure them with a pin. Remove the 2x4's and move on to the handles which were easy to attach. Now fill the case with oil. The unit doesn't come with oil. It takes SAE 10W30. The battery came fully charged. Connect the battery terminals, fill with fresh gas and you are ready to go! The whole process took about a half hour. Operation/Starting: The generator started up instantly. Pull the cord or turn the key and BAM! Push the choke in half way then all the way (open) and it idles nicely. This generator is quiet! I have a half acre and in the front of the house you could not hear the generator running in the back yard. So I decided to start testing with my pool. Yes, I ran a cord to my pool filter and it went from idle to full throttle. Powered the pool filter no problem. For me this will power three essential things during an outage: Refrigerator, chest freezer and tankless hot water heater. I hooked them all up and this thing ran with ease. Cranking at full throttle it wasn't as loud as I thought it would be - my lawn mower is just as loud. Storage: I picked up a cover here on Amazon for $10. It does the trick and will keep dust off the unit until I need it. Everything on this generator is easy to get too, see and adjust. Even without the manual at hand there are stickers everywhere that show you what each item is and what information you should know about that item. For example, the gas shut off valve has a sticker above it with the label and diagram of which position is on or off. Each component has a sticker above it. So, for storage you can drain the gas easily by using a 10MM wrench to loosen the gas filter cup and remove. Take a plastic soda bottle with the top cut off and you can catch the dripping gas. Of course do this after running engine dry. As for gas, every time I fill up my 5 gallon tank I always put at least two ounces of Stabil in it. You should too! Disconnect the positive battery terminal before covering. Put a board down for the wheels - concrete can do bad things to wheels if they sit long. Unhappy Notes: Oil: The unit didn't come with oil. It wasn't a problem as I went to the local car parts store and picked up two Quarts of SAE 10W30 Synthetic motor oil. The generator takes 37 Ounces or 1.1 Liters. A quart has 32 ounces in it so you will need two quarts. Start it up with one quart filled, let the oil move into the engine, shut it down then top off. However, filling with my long nose funnel was a breeze - very easy to get at. Wheels: The instructions say to make sure the fill valve is facing out when attaching wheels. Well, this unit came with air filled tires but there is NO valve! This concerns me because if I need to fill air into the wheel, well, how will I do it? Tires loose air with pressure. I just wish they were solid through out - no air - and I hope they stay inflated. Handles: Putting the handles on was easy however they are short. I stand 5'8 and when carting the unit you have to walk slow. Anyone taller than me would have an awkward angle when walking so close to the generator. The handles are only 10 inches long so you are very close to the generator when you walk. Also, the muffler faces you when you walk so you have to be careful when grabbing the right handle as it is right in front of the muffler. HOT Wrap-up: PROS: Quick start either by pulling cord or turning electric start key 7000W running power with 8500W surg 7 Gallon gas tank with gas gauge Volt meter Muffler on engine Four 120V AC outlets Easy to read info stickers placed throughout the machine Breaker switch Low Oil auto shut off Auto idle switch QUIET - 72 dBA Four Rubber motor mounts 16HP OHV engine Engine parts/components are all at easy reach CONS: Wheels - no inflation valve - flats/Air loss = new tire?? Handles - short in length Doesn't come with oil - need to purchase 2 Qts of SAE 10W30

Great choice!

We got to use this for the first time in the recent flooding (Binghamton / Owego, NY area, September, 2011), and it did very well. I have not made connections to the house yet, so we used extension cords for the fridge and freezer. I appreciate the rugged construction of the components. Rubber motor mounts, rubber feet and solid core tires make a smooth machine. It is also reasonably quiet. A great value!

Great deal and works very well.

I bought the XP8500e for my race car trailer and it worked great. Just lost my power in my house for 5 days due to storms here in Ga. and this generator ran my house and never let me down. I have friends looking to order this one any day.

I live in Louisiana. Our electricity goes out quite often; because of bad weather. I bought this generator because it looked like it would best fit my need. I have not had to use it so far since it was delivered, however, I did put gas and oil in it and it runs quiter than the one I now have. The older one is a smaller generator and I could only run a few things at a time; the freezer at night, leaving me with no fans to sleep under.

Well Pleased after 1 year

I have had the Duromax xp8500e for a little over 18 months now and replaced a Honda 4400 watt generator with it. Our power goes out often and recently ran the generator over 8 hrs due to a failure in the area. Total run time would be estimated at over 60 hours thus far. I have read the other reviews and decided to post this one. I have not experienced any problems other than the tires leaking down over time. I use it to power the entire house and just pay attention to how much and what I'm using such as cutting the hot water pump off while taking showers since I have 2 4000 watt elements in an 80 gallon tank. After showering and running the water pump I cut the hot water heater back on. The 2 refrigerators and 2 freezers as well as lights, tv/satellite are all fine during this process. Manage your consumption, use a transfer switch and inlet box, it makes things much simpler and very quick. Change the oil after the first couple of runs due to break in. Shut the gas off and let the motor run out then cut the switch off. It starts occassionally on the first pull and if not on the second just to see if it will but use the electric start. It is quiter than the 4400 watt I had and the idle down/up according to demand works great. On several occasions I've had to take it to work on construction projests, buildings where there was no power available and operated fine. For the price and wattage this one has been excellent for me.

First time generator buyer is IMPRESSED

I bought my XP8500E generator from Generator Factory Outlet. I also had to have a warm body at the house to direct the driver to unload, but he did have a lift gate ($50.00 extra charge, no problem). I unwrapped the unit, oiled and gassed it up and hit the key ONCE and it started right up. Hey, its probably made in China, but the fit and finish and overall quality was excellent. I connected it to my water pump and fridge and it barely slowed down. Its easy to move with the wheel kit,too. I looked at generators of this rating that cost a LOT more, then bought this one for $899.00 plus the $50.00 for the lift gate. Shipping was INCLUDED in the price! No problems, no hassles. No more losing all my food in the fridge when the power goes out for 24 hours!

Not as quiet as I would have hoped but none-the-less is a great product. Will tap it into my main household line to run everything when the power goes off for 36 hours again.
