Fits in our 5th wheel

Bought this in February with plans to use it with our 5th wheel. Size is nice and it powered up our appliciances and batteries. We haven't had a chance to test it with one on the A/Cs yet. If it works well to run at least 1 AC we will buy a 2nd one and the combiner cords.

Love the remote start and the low noise level, but,,,

I now own two Westinghouse Inverter Generators. I bought the iGen2200 a few months ago and liked it so much I bought the iGen4500 to use at home and with my RV. It is the largest inverter generator I could find and the price was good. The generator is very quiet, extremely easy & convenient to start with the pushbutton or the remote fob, but, there are some things I don't like. The first is that the 30A receptacle is upside down. I had read about it in other reviews, but, didn't grasp the significance. I cannot completely plug in my RV plug because the plastic cover interferes with the plug. It also falls out easily since the weight of the wire is above the plug. The other thing that I don't like is more than just an annoyance. I bought the 4500 (3700 running) watt generator to be able to power the air conditioner in my RV when not connected to shore power. My RV has a 30 Amp connection. When plugged into shore power my AC, refrigerator, coffee pot, ice maker and lights (all LED) are all powered with no issues. When I try to run my AC only with my generator, it frequently trips into overload status. This generator should have no issues running my AC (3,700 Watts/110V = 33.6A). So, it is either defective or the rating is accurate. Maybe it needs a break-in period...? I've only used it on one camping trip so far. (Side note - I had ordered it for a cross-country trip. The original shipping date was well before my departure date, but, repeated delays in shipping dates caused it to arrive at my house the day before I returned from my trip). I could parallel both of my generators, but, the reason I got the 4500 was so that I didn't have to carry two generators, especially when one is as large and heavy as the iGen4500. I would give this a "qualified" recommendation depending on requirements.

Perfect Choice

I researched hours for what I hoped would be the perfect generator. I have a "whole house", 11K generator, but store sold me on whole house when in fact I would have needed another 6-10K. So last year during Irma, the whole house decided to konk out and left me with no power. I borrowed a 3700 and ran 2 refrigerators, freezer, computers, tv & fans. It saved me as power was out exactly 6 days. So I settle on the iGen 4500 because of features and price and I can see I didn't make a mistake. I'll get to the cons but the pros: easy start and far quieter than I imagined. Had to keep going outside during test run just to make sure it was running. Love all the information on the digital screen and didn't even cough when I put a load on it. Seems to be frugal with the fuel use. The cons: First off the panels, all of which had to come off in order to access important pieces. The back for the battery, wire to connect battery was tucked so far under the unit you couldn't see it thru the access panel. They recommend draining fuel from the carb bowel after use but you have to take the five screws out of the side panel to access the unit. Why not use butterfly screws/bolts to make this process so much easier. On to oil access. You can see it but if your hands are big getting to the dip stick and getting it off and rethreaded takes some doing. Those are all minor details the company should be looking at and wouldn't deter me from buying this unit again. I don't want to have to use it but wow, what a great piece of mind I just bought. Had two other brands picked out but am sure this is the right one. With continued use maybe I'll update down the road.

Great Manual and easy to operate

I waited until I used this generator to write this review. Getting the generator operational was very straight forward as the instructions in the owners manual are well written and easy to follow. We used the generator to run the air conditioner on our RV this past weekend. The generator noise was not a factor as we slept in the RV. The remote start is a great feature. We are satisfied customers.

Good Generator

I purchased the generator to use camping. The generator appears well made. It arrived promptly with no damage in shipping. The packing protected the item very effectively. It started and picked up a load without any issues. The owner's manual was well done and informative. The generator height was 1 inch to tall to fit under the closed bed cover of my pick up truck ;(.

Perfect 'forgettable' product

I purchased the generator as we have a special needs child with various medical equipment and food that must remain refrigerated. I had not even done the initial set up until this week (9 months after purchase) when we needed it due to a prolonged outage. The instructions were very clear and well thought. As an example, the oil funnel threads into the fill port and oil container included is the exact amount of oil required. The battery had plenty of charge to immediately start and get rolling without much thought. Easily supplied energy for two refrigerators, a chest freezer and several pieces of medical equipment, rarely even automatically increasing the RPM to supply the load. It ran quietly and used a small amount of gas during the first 5 hours of running.. I say it is forgettable as we could continue providing the care for our child and focusing on the rest of our life without another through of the power being supplied. Very happy with the purchase!!

Igen4500

Generator works sonetimes, issues that the automatic choke doesn’t work? So I need to use a manual choke other than that it works. But It won’t stay running? I could use some technical guidance from you if possible on what to do.I could use some technical guidance from you if possible on what to do

Powerful Luggage

Bought this to have a backup power source for Freezers and electronics when the power goes down. Have not had a chance to test it yet, but did fire it up, that was easy and it was pretty quiet. I like the Luggage type pull handle to move it , makes it easier on us weaklings.

Great Generator for the value

My brother bought one and we used it for icefishing. 36 below zero and no problem. Remote start is an awesome feature. I was so impressed that I bought one. The digital display is a great feature for telling you how much run time is left on the tank. I am looking forward to using it for camping.
