The Krieger 3000 Watts inverter is a modified sine wave inverter built especially for the average layperson who isn’t exactly an expert electrician. It is designed to be easy to set up, easy to run and easy to maintain, with minimal care or concern. Packed full of features, the Krieger is an excellent power inverter.

WHAT WE LIKE

The Krieger 3000 Watt Power Inverter is not here to mess around. Packed with a ton of safety and convenience features, this plug-and-play inverter comes ready to help. With 3-ft battery cables ready to go, all you need is a battery to get started. 

The built-in LCD display gives you a constant read-out of the information you need to stay safe, including current power draw, system temperature, and more. If any problem occurs – such as short circuit or an overload of some sort – not only will the power inverter warn you, it will shut itself off to protect itself and you.

The 3000 Watt size is perfect for most anything you need, but should you require a little more “oomph” Kreiger has you covered with a built-in hardwired kit for applications larger than 15 amps.

PROS

  • LCD display for information and safety
  • Operates at 3000 Watts continuous
  • Smart shut-off features when problems detected
  • Easy to set up, easy to use
  • Comes with a three-year warranty

CONS

  • Modified sine wave power means some appliances and electronics won’t work as well
  • Only two outlets means minimal simultaneous operations, but two USB ports makes up for it somewhat

The Go Power! Inverter is another solid entry in the field. With two more outlets than the Krieger, you know this is made for convenience. It doesn’t have all the features as the Krieger, but it can still run your applications regardless.

WHAT WE LIKE

The Go Power! Inverter is a solid entry in the power inverter field. It might not have all the bells and whistles of the Kriger, but what it lacks there it makes up for in pure usefulness. With four outlets, you know this is built to run multiple applications at once. 

The Go Power! Inverter hooks up to existing systems with relative ease, but it’s not quite as easy or as convenient as the Krieger. There are kits available to help you with your hook ups.

PROS

  • Three outlets plus one USB plug mean many applications can be run at once
  • Durable, solid construction
  • Boasts five different protections systems: thermal, overload, over voltage, under voltage and low voltage protection
  • Pure sine wave means more applications and appliances can run smoothly with the GoWISE

CONS

  • One year warranty is good, but not great.
  • Multiple reports of the company being difficult to work with concerning said warranty
  • Not as easy to hook up as some other model inverters

The GoWISE is a pure sine wave inverter, which means it already has a leg up on the Kriger and Go Power! Models. Pure sine wave inverters are able to run more things easier, which might at first glance make this one a slam dunk. However, a higher price tag and some less-than-convenient features sets this back enough to make it a good choice, although maybe not the best one.

WHAT WE LIKE

As said above, a pure sine wave inverter is better at handling some things. Depending on your need, this might be an important point. Newer, more complicated electronics such as laser printers, medical equipment and high-range appliances might not work if you don’t have a pure sine wave inverter. Always make sure to do your research to see the needs of the appliances you will be running!

PROS

  • Three outlets plus one USB plug mean many applications can be run at once
  • Durable, solid construction
  • Boasts five different protections systems: thermal, overload, over voltage, under voltage and low voltage protection
  • Pure sine wave means more applications and appliances can run smoothly with the GoWISE

CONS

  • One year warranty is good, but not great.
  • Multiple reports of the company being difficult to work with concerning said warranty
  • Not as easy to hook up as some other model inverters

The AIMS Power3000 is a pure sine inverter that can power your complicated and newer electronics. Perfect for boats, RVs or any other vehicle or situation you can think of.

WHAT WE LIKE

This is a decent, solid power inverter, even if it lacks a lot of the bells and whistles that come with some of the other inverters. As a pure sine inverter it is capable of handling newer, more complicated devices, but with only two outlets and one USB port it can only power so much at any given time.

PROS

  • Pure sine wave means this can handle any appliance or electronic you want
  • Short circuit protection as well as low and high voltage shutdown

CONS

  • Only three outlets total means minimal use at any given time

The Haitral 3000Watt Power Inverter is a lightweight addition to the 3000Watt power inverter lineup. As a modified sine wave inverter its use is limited when it comes to certain types of applications, and with only two outlets (and no USB ports) you won’t be able to power as many items as you might with other inverters.

WHAT WE LIKE

As a smaller entry, this isn’t a bad power inverter. It’s just that, when you put everything together, this particular model doesn’t have the “wow” factor that some of the other interters deliver. We like that it’s smaller and much more manageable, and the ease of setup (two included cables; that’s it) makes that a breeze.

PROS

  • Small, lightweight
  • Comes with a ton of safety features and protections

CONS

  • Only two outlets total, with no USB ports
  • Modified sine wave, instead of pure

How Does a 3000-Watt Inverter Works?

3000-Watt inverters work by drawing power from a DC battery – such as a car or boat battery – and converting it to usable AC power. Because many smaller applications only use a fraction of the total 3000 watts delivered, multiple things can often be powered at one time. 

Some inverters – with modified sine waves – are not able to power newer, more complicated electronics, while more powerful pure sine waves can power pretty much anything you throw at them. This means that microwaves, toasters, computers, radios and even heavier power users such as hair dryers can be powered, offering you the comforts of home no matter where you find yourself.

Conclusion

As you can see, there are a lot of different 3000 Watt power inverters available on the market today. Of course, what you need depends a lot on how you’re going to use it, but when it comes down to it, you need an inverter that offers dependability, safety and versatility. When you put those factors together, our pick is without a doubt the Krieger 3000.
