On top of our list, we have the Briggs & Stratton P3000 for its good friendly, user-friendly nature and efficient power output. This is no surprise coming from the very well renowned, Briggs and Stratton. Its very own unique quiet power technology helps make this unit not only quieter but also more fuel-efficient.

This is basically done by adjusting the speed of the engine according to the load on the unit in order to optimize fuel usage. Along with that this unit is also parallel capable which means it will deliver twice the power output when parallel connected with a similar model without even having to connect it to the main power outlet.

With a run time of up to 10 hours at quarter load, the Briggs & Stratton P3000 operates at a running current of 21.7A. This long run time means minimum disturbance and having to refuel less often. The power output is clean and safe in order to safely power appliances. It features a 1.5-gallon fuel tank which is also one of the reasons behind its long run time.

This unit also has some user-friendly features including the LCD screen which displays the run time, amount of power used, and also when the unit requires maintenance. The USB port allows you to directly charge electronics and a telescoping handle on the unit makes it easier for you to carry it around.

On the downside, it is quite heavy which reduces its portability and increases the effort required to move it around.

In conclusion, the Briggs & Stratton P3000 offers good value for money and also offers parallel capability at the same time.

The WEN 56380i is a sturdy inverter generator even though it seems to be quite small. It delivers the power required to run appliances in an RV using a NEMA TT-30R plugin. All the key outlets in addition to the USB ports are placed on the unit and the power it delivers can safely power even the most sensitive of electronics.

The portable inverter generator is specially built to work as efficiently and quietly as possible. While delivering quarter-power output, noise levels are similar to a window unit AC. 57 dba is not very loud for an inverter generator delivering 3000W.

The fuel shutoff feature in the WEN 56380i makes sure of the fact that the fuel line is shut off completely before the system turns off. Any remaining fuel in the carburetor is used up which helps prevent any stale fuel in the engine hence eliminating any cause for corrosion in the system.

This also helps improve the lifespan of the system making it more durable. Digital fuel and load display make it much easier to keep an eye on fuel levels and power output. Run times are rated at 8 and a half hours at half capacity using a 2.2-gallon fuel tank. Last but not the least, this unit is also parallel and capable of greater power needs.

It doesn’t have many cons but some users might not appreciate the boxy design.

Best 3000-Watt Inverter Generator Buying Guide:

If inverter generators are new to you, don’t worry because we’ve got that covered. Here are some of the things you need to look for in a good inverter generator.

1. Portability:

Look for units that are lighter in weight because at some point you will have to move it around and trust me you will be grateful for this advice. If you can’t find a good inverter generator that is lightweight, look for one with a handle and wheels in order to make it easier for you to move it. This is especially important if you want to use the unit in RVs or for camping trips.

2. Noise levels:

If you’re using the unit indoors or at night, it would be much more comfortable to have one which has a quieter operation. You can also choose to look for some muffling mechanism in case it turns out to be too noisy for you.

3. Eco-friendly:

If you’re keeping it indoors or using it inside an RV, it is important that it is CARB and EPA compliant because this ensures that it will not be producing toxic exhaust fumes which could prove poisonous in a closed environment.

4. Power requirement:

This is extremely important! Make an estimate of the amount of power you require to run your respective appliances and look for inverter generators that supply that much power. Don’t go for ones that make too much or too less power as compared to your requirement. You can also choose to invest in two parallel capable inverter generators instead of one huge unit.

5. Budget:

This is also a very important consideration. Make sure you have set a budget limit otherwise you will end up spending a lot and regretting it later.

Conventional Generators vs. Inverter Generators:

A conventional generator basically delivers AC power from its power outlets. This is how it functions. However, an inverter generator works differently. It produces power in phases. Firstly, AC power is produced which is converted into DC which is finally converted back to AC. This is done in order to ensure a safe and clean power supply that can be safely used for sensitive gadgets.

However, inverter generators usually cost more than conventional generators as they are relatively new and have a more advanced design. But generators offer good value for money they as they are more fuel-efficient and much quieter during operation. When considering power output, conventional generators take the lead because they are more powerful in general.


Frequently Asked Questions
