5 Best 400 Watts Inverter

Searching for a portable alternating current (AC) that can take you on a road trip without stopping? Then a 5 Best 400 Watts inverter will do justice to that.

Though new generational vehicles now come with a built-in power inverter, there are still some that do not have. Therefore, having a 400 Watts inverter will be an added advantage to you.

You will not only be needing this 400 watts inverter for your vehicle alone. You can still use it to power your household appliances or even office equipment.

This guide on 5 Best 400 Watts Inverter is here to give you an insight on how to choose a perfect inverter for your vehicle.

Hence, in this PowerVersity buying guide, I will be covering some vital details to guide you in choosing the best 400 watts inverter.

First of all, I will be giving a brief discussion on what a 400 watts inverter is about.

Best 400 Watts Inverter; An Overview

Best 400 Watts Inverter; An Overview

When you talk about inverter power, you are actually talking about the power source which converts the direct current into alternating current. This alternating current is what then generates some powers, one of which is knowns as a 400 watts inverter.

This 400 watts is similar to the other alternating current that comes from the inverter through the conversion of DC to AC. The power either comes from a power source or via battery.

So if the power source from the inverter gives 400 watts to the inverter, it means 400 watts power inverter.

Furthermore, if you have a 400 watts inverter, just know you a converting the power of the battery into 120 VAC.

A 120 VAC is an electrical flow of current from negative to positive and from positive to negative. This is calculated in 60 Hertz, meaning it changes every 60 seconds per day – from 0 – 120 volts.

Therefore, a 400 watts inverter can power any appliances or equipment loaded to it. With full freedom, you can charge up all your office equipment.

In that case, let me give you an example of what a 400 watts inverter can power or run. There are some daily use household accessories a 400 watts inverter can run, this includes:

Television, laptop, DVD player, blenders, cameras, tablets, and even refrigerators, etc. Most of this equipment uses up to 80 -400 watts to be able to run smoothly.

Likewise, television runs from 80-400 watts, blender from 200-400 watts, and a large laptop may consume from 100 – 400 watts inverter.

Basically, if you are planning on running equipment on a 400 watts inverter, you should, first of all, calculate the watts of each of them. The watts of all should not exceed the 400 watts inverter, if not the voltage may fluctuate.

Important Features To Look Out for In A 5 Best 400 Watts Inverter

Important Features To Look Out for In A 5 Best 400 Watts Inverter

Once you make up your mind going after a 400 watts inverter, there are things you need to have in mind.

Similarly, when purchasing a good power inverter, this is one of the best criteria you should aim at. This is because the appliances you are going to use have a life cycle and this life cycle will depend on the type of power source it gets.

Thus, here are the things you should not overlook when purchasing a 400 watts inverter.


Safety will determine the enabling features the appliances will be needing.


Here you have to consider the wattage you are going to run on the inverter. For instance, if a blender uses 200 watts to be able to power, then a 400 watts inverter should do that.

Again, using a microwave on a 400 watts inverter doesn’t go well. For example, a vacuum cleaner makes use of 500 watts, then imagine what will happen if you plug two electricals on the 400 watts inverter.

That would become a disaster to the inverter. You will have to calculate the wattage of the appliance, then add it up to determine if your 400 watts inverter can handle it.

Note that when you finish calculating, a comparison of your inverter and that of the appliance capacity, you will have to leave about 150 – 200 watts differences.

That is to say, if you check the wattage of the appliance like a blender which is about 200 watts. Then you will be needing a space of 150 watts to match up the 400 watts you have.

The reason for the calculation is for you to give room for a short period of overheating via the appliances. If overloaded with many gadgets or appliances, it may blow up the inverter.

Hence, wattage is a necessary thing to consider when using your appliances on a 400 watts inverter.

High quality

In this case, you will be needing a 400 watts inverter built with high-quality software.

This has a lot of benefits with the quality software you won’t have any problem using your appliances.

Remote control

On purchasing a 400 watts inverter, look for the one with remote control. This is for easy operation – with that you can operate from anywhere in your office or house.

Again, it will make your work more handy and easy.

Battery type

No time should you purchase an inverter without knowing the type of battery it uses. To be on the safer side, check for the battery type in order not to make a wrong choice.

Power drain

When there is no alternating current (AC) available, the inverter draws power from the direct current which is the battery to power AC gadgets.

Therefore, you must be sure of the inverter you are purchasing if it can enter idle mode. The idle mode is when the inverter goes off when it is no longer in use.

So the inverter should be able to detect the idle mode when you are not using it.


The working mechanism of your inverter will be determined based on how efficiently it works. If you make a mistake buying a 400 watts inverter without knowing the output ability then you are not on the right track.

The ability of the inverter to work for a prolonged hour when there is a power outage will be effective in getting your work done.

Having said much about what to consider before buying the 5 best 400 watts inverter, let’s quickly look out the types.

Types of 400 Watts Inverter

Types of 400 Watts Inverter

Categorically, there are three major types of an inverter. But I will be listing and explaining them below.

Pure sine wave

A pure sine wave is one of the three major inverter types commonly seen in the market. Even though they are complicated, it is still most wanted in the market.

The name pure sine wave is because it doesn’t mix with other waves, hence the reason for the popularity in the market.

However, you should also consider the battery capacity. This will determine how long the battery will last, even though the output voltage is somehow like that of the electrical generator.

Square wave inverter

This is the cheapest among the three inverters. It converts direct current power to AC power by shifting powers, hence giving output power as a square wave.

Regrettably, a square wave inverter is not used by many people because most appliances can’t run on it. The reason is that most appliances in the market are made to run on a sinewave inverter.

Modified sine wave

This type is more complex than the square wave but less complicated than the pure sine wave. It is neutral, it doesn’t shift nor is it in any of the other two inverters.

It is just in between them. But the power does not shift like a square wave, nor moves straight.

Apparently, I have taken much time explaining other information about the 5 Best 400 watts inverter.

Therefore, let’s move to the comparison table.

5 Best 400 Watts Inverter; Final Thought

5 Best 400 Watts Inverter; Final Thought

On the discussion made so far on my 5 best 400 watts inverter, I told you that a 400 watts inverter is a power source which you can convert your direct current to alternating current.

Hence, the need to power your appliances using a 400 watts inverter. However, if you must power multiple appliances, make sure the wattages are low.

There should not be a point that you will use a 400 watts inverter to power equipment that is up to 500W. It may damage the equipment and even the inverter itself.

I advise you purchase low power consumption equipment that can take up to 200 – 400 watts without creating issues to your inverter. That is if you want a 400 watts inverter.
