ETQ TG72K12 Portable Generator – Over 8,000 Watts of Power

25 June 2011 7,060 views One Comment

If you need a big, powerful generator that is reliable, high quality, and can be used with sensitive electronics then the ETQ TG72K12 is the one for you.


We had a big ice storm roll through this past winter. We get them a lot in Virginia on the mid-Atlantic east coast of the US. When a winter storm comes through, the areas a little further north tend to get a lot of snow, whereas places south will get a lot of rain. It’s usually a crap shoot as to what we get. It could be all snow or it could be all rain depending on the track of the storm and the air temperature. Mostly though, we end up with a lot of ice. This means a lot of downed power lines that fall from the weight of the ice clinging to them. Which means the power goes out a lot.

Usually the power company and linemen work pretty hard to get things back up and the power back on in a day or so. But sometimes the blackout can last several days. It pretty much sucks during that time.

Well, after that last storm hit, I saw that my neighbor had most of his lights on and the TV and heat running like nothing was wrong. So I asked him what he was using. He’s a contractor and knows his stuff, and that’s when he told me about the ETQ TG72K12. That was enough to spark my interest, so I researched it in detail. Here’s what I found out.

The ETQ TG72K12 Puts Out a Lot of Power

The ETQ TG72K12 is a powerful portable generator with 8,250 max watts and 7,250 rated watts. It can handle a lot of energy hungry appliances. You should have no problem powering a 40 gallon water heater (3,000 watts), a coffee maker (1,500 watts), a 10,000 BTU air conditioner (1,500 watts), a personal desktop computer (800 watts), and a TV (350 watts). Sub out the water heater and you can add on a number of different items including your freezer (500 watts), a washing machine (400 watts) and your microwave (1,500 watts).

Before you buy a portable generator you should do a quick energy inventory. This means adding up the rated or running wattage of all of the appliances, gadgets and gizmos you want to use during a blackout, while camping, out on the job site, or in your RV. You also need to add up the starting or surge wattage of the biggest appliances that use to the most energy. The starting wattage is the short burst of power that is needed to start appliances and tools that have an electric driven motor. It can be up to 3 times greater than the running wattage on many appliances. The running wattage on your 18 cubic foot refrigerator/freezer for example may be 800 watts, but starting that baby up may require 1,600 watts. You should be able to find wattage information on the appliances themselves, usually on a sticker on the engine, or in the owner’s manuals.

Once you have the wattages all added up, you know what capacity portable generator you need to buy. Keep in mind too, you may not be running everything at once. You can always unplug and swap out different devices as you need them.

The ETQ Is Simple To Start

You won’t have any trouble getting the TG72K12 going. If you hook up a battery to it you can use the electrical start function and you won’t have to worry about wrestling with a pull cord. Just flip the switch to the “On” position to start the engine. If you don’t want to use a battery (it’s not included), then the ETQ will still start just fine using the pull cord.

Hooking Up Your Appliances to the ETQ TG72K12


The ETQ comes with two NEMA 5-20R 120 volt 20 amp GFCI duplex receptacles. NEMA stands for National Electrical Manufacturers Association which is a trade association in the US that represents the interests of electrical and medical imaging equipment manufacturers. They have guidelines for the types of certified receptacles that are used on portable generators. GFCI means ground fault circuit interrupter and outlets with this feature will shut down automatically if there is a leak of current. This is a safety feature designed to protect you and your equipment.

There is also a NEMA L5-30R 120 volt 30 amp receptacle for larger appliances that need more amperage, and a NEMA L14-30R 240/120 volt 30 amp twist lock receptacle. Twist lock receptacles are good to have because they create a secure connection between the cord and the generator. Sometimes portable generators, especially larger, stronger ones like the TG72K12, will vibrate and your extension cords can come loose. This is especially true if you have the machine running for a long period of time. With a twist lock receptacle you don’t have to worry about this.

Also remember that the electrical cords you use need to be able to support the wattage requirements of the devices plugged into them. The extension cords you use with the TG72K12 need to be able to handle 30 amps of current at 120 to 250 volts.

The other option you have with the ETQ is to use a transfer switch to hook it up to your home. These are fantastic options because they allow you to run all of the appliances that are hardwired to your home, like your furnace fan, sump pump, and water heater. You can even use your light switches inside and all of your wall outlets. Transfer switches connect directly to your home circuit breaker and will cost you a couple $100 or so, which in my opinion is money well spent. I’d also recommend having a certified electrician install it as it may be just a little too complicated for the average do-it-yourselfer. Another nice thing about a transfer switch is that you just need one extension cord connecting the TG72K12 to the switch. Then you can plug your appliances into your wall sockets just as you normally would.

Safely Power Your Sensitive Electronics

The TG72K12 has an alternator designed using unique technology called “Clean Sine Alternator Technology” that creates a low total harmonic distortion (THD). THD, when talking about engine alternators, refers to the level of distortion of the electricity produced. The lower the distortion levels and hence the THD, the better quality and cleaner the power produced and the less likely it is to cause power surges. When the THD is over 6% electrical components and circuits in devices like personal computers and DVD players can be damaged. The ETQ TG72K12 produces electricity with a THD of less than 5%. So you can rest assured that all of your electronic equipment will be safe plugged into it.

For A Big, Powerful Portable Generator, the TG72K12 IS Not That Loud

Now you can’t expect a 14 hp, 8,250 watt portable generator to be quiet. On the other hand you don’t want to hear it all the way down the street in your neighborhood during a blackout. The TG72K12 puts out about 70 decibels of sound from 23 feet away. This is on par with other portable generators in this wattage capacity and not that much louder than most 4,000 watt generators which on average put out about 68 dBA at 21 feet away.

To give you an idea of what this means, 70 decibels is about like street noise in the city. You can talk over it and it’s not so loud that you can’t tune it out after a while. 60 decibels is about the level of a normal conversation. There is a video below where an owner is able to talk to the camera over the sound of the generator and you can hear him just fine.

A couple of owners mentioned in their reviews that they could carry on a conversation about 10 feet away from the unit.


The ETQ TG72K12 Gets 4.5 out of 5.0 Stars

Check for the Best Prices for the ETQ TG72K12 Portable Generator

The Good

  • Easy to move around for its size – It has heavy duty solid foam rubber tires and a handle that make for easy pushing. You shouldn’t have any trouble even though this baby weighs in at over 200 lbs. If you need to lift it up into your RV or truck, you’ll need some help though. The unit also comes with a special bracket that allows you to hook up to a mini crane or cherry picker and lift it up. That makes things a lot easier.
  • Auto throttle – The ETQ will throttle down or up depending on the load. This helps to save fuel and increase run time and overall efficiency.
  • Very affordable – An 8,250 watt generator for under $800 plus free shipping is a really great deal in my opinion.
  • Great control panel – You get a lot of features on here including a fuel gauge and an hour meter.
  • The engine shuts down when the oil is low – This a great safety feature and can really save the engine especially when you’ve been running it for hours and don’t think about checking the oil.

The Bad

  • Not CARB Compliant – This means that the TG72K12 cannot be sold or used in California because it does not meet the California Air Resources Board’s strict engine anti-smog emission guidelines. You can use it every else though with no problem.
  • Only a 1 year warranty for consumer use and a 90 day warranty for commercial use – It would be good to see a longer warranty, especially for a high capacity generator.
  • Doesn’t come with a battery – You’ll have to buy this yourself if you want to use the electric start function. You don’t have to have a battery though because you can just use the pull recoil starter.

    After reading many positive reviews I purchsed this generator. The unit is heavy duty and has lots of good features for the price. Much quieter than I expected. During the recent (Oct 2011) snow storm here in the Northeast I was glad to have this unit because most of the Northeast lost power including myself. After starting the unit it seemed to run fine for several hours then all of a sudden there was a problem. The motor continued to run but there was no power (juice). Since it was late I decided to shut down the unit. The next day it was no better. Curious, I checked the output voltage at an onboard receptacle, it was fluctuating between 12vac and 59vac. I contacted ETQ about the problem but they told me the cost of repair would be mine because it’s out of warranty. Yes, it’s out of warranty but I didn’t have a need to use it until just recent and it only has a total of ** FIVE ** hours on the unit when it failed. It’s still brand new. Even though I appealed to ETQ that they should stand behind their product regardless of the expired warranty they continued to play the warranty card game. Next time I will pick a unit with a multi year warranty.
