Just think that you are on vacation with your car, suddenly you need to work on a laptop, but it is out of charge. With a power inverter, you can charge and work in your laptop gracefully at the same time. In-home, your appliances will get smooth power flow even your area has power shortage issues. You can say, a power inverter is a device that saves power for your devices in an emergency. Now the main question is, what size power inverter do I need? No worries, I will give the information, and you figure out how big the inverter you need.

Types Of Power Inverter
The use of inverters is growing day by day. Once, the inverters were considered as expensive devices to use for large projects. But modern inverters are capable of running electric devices, home appliances. Moreover, you can get the best power inverter for trucks also. In the case of a frequent power cut, the inverter provides sufficient power supply. Based on the output characteristics, inverters come in three types. They are:
Square wave inverter:
Among all the inverter, the square wave inverter is the simplest one. With this inverter, the straight DC converts to an unstable AC phase. The output is the square wave, where AC is not pure. This inverter is cheap and has a simple construction.
Quasi sine wave inverter:
This inverter type is a little bit complex but simpler than the pure sine wave inverter. The power convert process takes some pause before the phase shifting. In the square wave, the phase-shifting from positive to negative goes roughly, and in the sine wave, the phase-shifting goes smoothly, but in the modified sine wave inverter, the phase-shifting takes a small pause then converts.
Sine wave inverter:
The most complex inverter is the pure sine wave inverter. It is nothing like the square inverter or the modified sine wave inverter. You will get a pure sine wave by taking a square wave from the square wave inverter then altering the process. This wave is efficient and consumes less power. You can use the wave outputs for your individual power requirements easily. This reliable wave inverter is best for personal and commercial use.
What Size Power Inverter Do I Need
Before purchasing or installing the power inverter, you have to calculate the power need. If you consider the inverter for your car use, then you should be careful about the issue of overloading the electrical system. To make the correct calculation of your power requirement, check out the devices you will need to run with the inverter. Be it one device or more; you have to know the power amount you need to run with the inverter.
The wattage requirements are printed on the devices in amperage and voltage. Add the wattage power of your required devices between 10% – 20%. The number you get here is the size of the inverter you will need to run those devices. You can get a larger one if possible. Let me give information about some common devices and their wattages:
- The cellular phone comes with 50 watts.
- A microwave comes in 1200 watts
- A laptop is 90 watts
- LCD TV is 250 watts.
These are some essential devices that we use on daily purpose. The numbers vary from device to device. Make sure to get the correct watts number before going for the inverter.
Let’s say, for example, you will plug your cellular phone, laptop, TV in the inverter. So, the total power you will use is – (50+90+250 = 390 watts). With this subtotal, add the safety margin of at least 10% – 20%. Then the total amount comes: 390 watts +20% = 468 watts. This number means you will need an inverter that can provide 500 watts or more power. You can also figure out the power requirement with a simple formula, and that is: Amps x Volts = watts.
You may get confused is a big size inverter is a better option to use for home or car. Well, if your devices require more than 600-watt power requirements, then pick the best 2000-watt inverter for use. You will not have to think about enough power requirements for your device. And another thing is, you can add more devices in your plugging list. But do remember to calculate the power requirement.
Make sure the power inverter delivers continuous output because some inverter has peak output where the inverter shuts down and restarts the power supply after a certain point. It is totally harmful to your devices.

Benefits Of Power Inverter
The first benefit I will say is to make life simple and smooth. With the inverter, you can take a long ride with your family charging your devices and a coffee maker to make your refreshing drink on the way.
In some countries, there are places where the power cut is a big issue. For them, the inverter works as a life-saving device. Just think you are doing an important task on your computer or watching breaking news, then the power is gone. If you don’t have an inverter, then you will lose your work instantly, and your TV will face certain damage. The power inverter will not let your work vanish just like that. It will make your device work for some time.
You can’t take the inverter as the power convert device; it is a charger also. But you have to look for the inverter that works as a charger too.
The best thing about the inverter is they are noiseless. You will not get a single noise when it is working. Also, the inverter doesn’t produce smoke while working. It is an environment-friendly device.
You don’t need oil or petrol to run the inverter. You can say the running cost of the inverter is zero. It is a big thing as you can save lots of money by using the inverter. You will not face any regular breakdown experience with the inverter.
The inverter starts as soon as the power cut happens. It doesn’t need any manual maintenance.

Frequently Asked Questions
Have a look at this section to find a solution to your questions. Here we added most of your questions that you ask us several times.
Are power inverters bad for your battery?
No, but if you inappropriately use the power inverters, then the battery will get down.
How much battery power does an inverter use?
A 12- volt inverter with 100 watts needs 10 DC amps of the battery power.
Does an inverter use power if nothing is plugged in?
Yes, the power inverter draws power even no device is plugged in.
Can I leave my inverter on all the time?
No, if the inverter power is not required, then shut off the inverter.
How do I turn off my inverter when not in use?
When the battery is fully charged, then just turn off the switch of the inverter.
While choosing the power inverter, the important part is to understand what size power inverter do I need. So, when you are selecting the size, determine the battery voltage for the power you need. Generally, we use the 12-volt battery, so pick a 12-volt inverter for your use. Power inverters come in different sizes by measuring the watts. Know the required power you need to run your devices then go for the best power inverter for home.
