Generac 6866 iQ2000 Ultra-Quiet Generator Reivew

If you are looking for an ultra-quiet generator that is also reliable, Generac is a name to be remembered. The company has a wide range of products available, including their gas-powered Generac 6866 iQ2000 Ultra-Quiet generator.

Generac iQ2000 generatorThe Generac 6866 iQ2000 Ultra-Quiet emphasizes a powerful, yet quiet, engine. The generator uses an overhead valve (OHV) engine, the benefits of which include smaller packaging sizes and a less compact drive system. This allows the Generac 6866 iQ2000 to be not only small and transportable, but very lightweight when compared to traditional overhead camshaft (OHC) engines. The operational volume of the engine mostly lives up to the name.

Even when under a heavy load, it only produces about 75dB. When idling, it’s well under 70 decibels. This is due to digital inverter module used within the engine, which converts DC power to AC. The sound will increase slightly when the generator is at maximum capacity or running in turbo mode, but will not come close to reaching the higher volumes found in many other competing generators.

Capacity and Run Time

The gasoline-powered engine in the Generac 6866 iQ2000 is capable of producing 1600 continuous watts, with its peak rated at 2000 watts.

Even with a peak power rating of 2000 watts, it is very unlikely you will be able to run your entire house on this generator. However, it will power some other emergency essentials: AM/FM radios (≈100 watts), laptop computers (≈60-100 watts), mobile phones (less than 10 watts) and televisions (≈200 watts).

All devices require a larger amount of initial power to start than to run. Many refrigerators require over 2000 watts to start, and most operate at 600 continuous watts per hour. The Generac 6866 iQ2000, however, can be operated in parallel with a second device, doubling the power in case of such emergencies.

iQ2000 control panel

The Control Panel on the iQ2000 provides a convenient fuel gauge that estimates remaining run time.

The engine can operate for 7.7 hours at a 25% load – which means the generator can run for the advertised 7.7 hours while utilizing 400 watts continuously. For perspective, 400 continuous watts will not run the average refrigerator, which may require 700 watts or more. So, in practice, you might need to refill the 1.06-gallon (4.01 liter) fuel tank a few times – which really is an inconvenience more than anything. The efficiency of this generator is still quite impressive.

Cost to Operate

The generator is made to operate on gasoline alone. While there are some generators that can and do operate using multiple forms of fuel, this is a single-fuel engine. The fuel capacity sits at a somewhat small 1.06 gallons, which at current market prices for gasoline means users will pay under $3 to fill up the tank. If run at 25% capacity, this means that the 24-hour cost of running this generator will be around $10 dollars.

Portability

This makes the Generac 6866 iQ2000 a very cost-effective device, providing a lot of quiet power at a fairly inexpensive price. Although gasoline is a fairly lightweight fuel, it does weigh about 6.3 lbs. per gallon. A full tank in the generator will add about 7 lbs. to the generator’s overall weight. The dry weight for the generator is 46.2 lbs. (21 kg), bringing the operating weight with a full tank to around 53 lbs. (24 kg). Despite being a much lighter weight than most generators, it is still a relatively heavy device – so transportation is certainly possible, if not exactly easy.

Features & Maintenance

The Generac 6866 iQ2000 has several unique features that add to its value as a generator. The key feature, beyond the quiet engine, is the Smart LED dashboard. The LED dashboard features fuel level, remaining run-time, wattage use, and generator status. The dashboard helps users keep up with the generator and decreases the potential for unfortunate and unwanted surprises. The generator also has two 120 volt outlets and a simple dial that integrates all start, run and stop functions.

Because the engine runs on gasoline, regular maintenance will be required, including replacement of the oil. The included manual covers all of the necessary maintenance requirements for the product. There are some concerns with the product leaking fuel. However, these concerns are few and far between. Generac has fairly responsive customer service, which should help alleviate any issues that do occur.

Generac 6866: Conclusion

The 6866 iQ2000 is small and efficient, with a wide range of features that make it perfect for those looking for either short-term emergency backup power or for a smaller generator to take on the road. Although there are some issues that do exist with the generator, its positive features outweigh its negative ones.
