Excellent Generator for the price, but...

This is an excellent little generator and produces enough power for its size. if 2KW is what you need, this will do the trick. However, two things were disappointing. One, it is a lot heavier than the Honda equivalent. And two, it is no where near as quiet as the claim. It is downright noisy. Unfortunately, to get lighter and quieter, a Honda will cost you almost double the price. So for the few times you may need backup power, this will do just fine, and you will not be disappointed. But if you want to use this for camping, or extra power for a farmer's market or swap meet, it may be a bit too heavy and noisy for that. So 4 stars because it is a very good device. Minus one for weight and noise.

just what we needed

Our power company has been putting in a lot of new equipment. Had one 4 day long power outage that cost us our ref. contents and a good reason to buy a portable generator. Works great but only needed to keep food cold. Can do wyfy and tv if needed too

Wow. Great price, great brand, good product for the price

I purchased this at a sell price that was a hundred dollars off suggested retail which was a super buy. I had considered a Honda, but for the price, this unit is the bomb! Just a quiet as a Honda and MORE running watts, two 20 amp outlets, two usb charging ports and capable of charging a car battery. The Good: The generator is quiet, easy to set up and start, portable, comes with the battery charging cables, initial oil and worked flawlessly during my one hour initial test. I am very happy with the performance of it. The Bad: fit and finish has a lot to desire. The control panel was bulging at one corner and a screw on the panel was striped out.The spark plug is difficult to access, removing the plug wire is a chore. What could be Better: Filing the oil is also strangely difficult, they provide a funnel but the fill port is at a right angle to the unit and at the bottom. Basically when oil stops going in while filling, it is full (messy). Filling the gas tank is also odd. You have no way of knowing how much gas is in the tank. When filling, the spout of the gas can fills the opening which has a screen inside of it and you cannot gauge how full you have it. I see a big problem when filling a hot generator this way! Side panel is removable with two phillips screws, but hand twist screws would be so much better! This allows access to fill/check the oil, drain the carb for storage, and the air filter. I wish it had a digital read out for watts used but at this price point I understand. Why can't manufacturers engrave the maintenance schedule and oil type/amount, plug type, etc on the generator so it would always be handy?? Would I buy this again? Absolutely! The price, brand and running watts makes this an outstanding deal. I can live with the minor flaws.

Great generator - poor welds on wheel brackets

Opened the box to a brand new one thousand dollar generator. Everything looked great. Not a blemish anywhere. Started assembly and all is well. Wheels installed no problem. Handle, added oil, connected battery, gassed up, started and ran beautiful; again no problem. First time moving on wheels; problem. Both wheel brackets broke free from all but one weld. Impossible to move more than six inches without backside wheel pigeon toeing into the muffler. Hurricane Delta was fast approaching to my area of south Louisiana so I wasn’t about to return a good running generator. I would tough-out the inconvenience and deal with it after the storm. I wasn’t about to return the 200 pound unit and spend the time assembly another. The generator turned into a thousand dollar stand-by insurance policy. I’m otherwise happy for making the purchase. I’m not the first one to experience the weld breaks after reading reviews. Serious consideration for a Generac whole house standby generator purchase is now in jeopardy unless my complete satisfaction with warranty claim is made.

Great features

Purchased the GP5500 as a emergency power source after a recent hurricane that came from the gulf up through most of the state of Louisiana. I worked at a big box store and compared prices on line and decided to purchase the generac because of the good reviews and the price was great. I got it home and it took about thirty minutes to set up and got it running. The unit started on it's first pull. I like the no flat tires that is included. Like most reviewers stated, the unit is louder than some other brands. I prefer noise over no power at all. Luckily we haven't had to utilize the unit yet but hurricane season is in full swing right now.

IQ3500

Out of the box the IQ3500 i bought was leaking gas. Tried tightening the drain valve. Still leaking. Called Customer service and they were worthless. Told me I had to drive to a dealer one and a 1/2 hours away. Then told me they could not say this was under warranty even though was just out of the Box 2 weeks earlier. Decided to take it 15 minutes away to a small engine repair specialist. He found that the major gas line out of the tank was ripped. Cost me 60 bucks to get repaired. The customer service from these guys at Generac is absolutely worthless. I do not recommend Generac products on customer service alone.

Dual fuel awesome

[This review was collected as part of a promotion.] I’ve been using the Generac iQ3800 Dual Fuel Portable Generator for a while now, and I’m really impressed with how easy it is to operate. The push-button start works flawlessly, and the design makes it super portable with the built-in handle and wheels. It’s definitely built to last—feels very durable and reliable. I also appreciate the Economy Mode to help save fuel, and the LED display makes it simple to monitor everything. Great generator for both work and outdoor use!

Excellent quality and features at a reasonable price

This generator will be used for off grid camping. We already have a whole house Generac generator so it was no surprise to find the quality and feature we were looking for and much less expensive than the 'big name' generator. The IQ3500 came well packed and complete down to the oil and funnel. Everything except fuel for start up. After camping next to people running their generators, we wanted a quite unit and this is it. Surprisingly quite. We are very pleased with this purchase and are ready to go camping as soon as the weather breaks.

Iq3500

At this point I have not used IQ3500 for it intended purpose. Therefore I am unable to fully rate the product at this point However I do have one concern. The lack of servicing dealers and the availability of maintenance kits in my area More to come
