Best Power Inverter for Car 2021

Table of Contents

In today’s world, where technical devices are ubiquitous, plenty of devices need more than a USB port for charging. Power inverters are easy for converting the car’s electric DC into AC electric power. The conversion of DC to AC helps in charging a wide range of appliances and devices.

The cars have pre-installed USB ports for charging your and the passenger’s mobile devices. While USBs come in handy in most cars, but they are not compatible with high-power devices. 

Now, it is obvious that you won’t be charging a fridge in your car, but the power inverter makes it easier to plug and charge a laptop, hairdryer, or even a coffee maker. It makes the road journey smooth and hassle-free.

Shopping for a power inverter for a car may seem like a straightforward task, but it isn’t. You will find power inverters plugged into the cigarette port or a 12v accessory socket in the market. There are, however, many power inverters that can be installed in the car’s battery or fuse panel.

Below are the top power inverter recommendations that are currently trending in the market. We have detailed each product with pros and cons, so you find it useful to choose the right one.

Features To Look Out for Power Generator

Buying a power generator that has all the benefactors you want needs a checklist. For example, power inverters convert direct current to alternating current or AC power. But what should you look for before buying a power inverter?

What factors are deciding factors while buying an inverter? Here is the answer for you with a breakdown of each point in a detailed form. 

#1 Wattage

Before buying any power inverter, you must check for the wattage it can supply. Depending on the wattage, it can take the load of the appliance.

Low wattage battery tends to be smaller, lighter, and cheaper. These inverters are plugged into the cigarette lighter receptacle, and it does not take electricity from house batteries.

The low wattage can charge the phone or laptop on the go. It generally has 2 USB ports, although Bestek 200W power inverter is exceptional with 4 USB ports.

High wattage can provide enough power to run a toaster, vacuum cleaner, micro-oven, and charge the devices like laptops and cell phones. Choose the inverter depending upon the standard power need. Put 15-20% margin on standard power load. 

For instance, a coffee maker requires 300w, a laptop 100W, and a phone 25W. If you add up, it becomes 425 W, which means you should buy a power inverter with a 500W power supply.

#2 Safety Features

You shouldn’t proceed to buy a power inverter without comparing the safety norms and features. The inverter should allow you to monitor voltage fluctuation, and it is a plus point to know the voltage before connecting the device.

Knowing about voltage protection, overheating, and short-circuit protection helps you narrow down the inverter with safety features.

The products listed above have these protection features making them suitable for your car. Make sure the power inverters have a thermal cooling fan to balance overheating of the inverter. 

#3 Size/Weight

While traveling, who wants a heavy inverter onboard? It is efficient to use if the size is compact and lightweight. In-car, there are only a few places to keep the power inverter, considering the plug-in inverters. 

A smaller unit means you don’t need to brainstorm too much on finding a place to keep the power inverter. The Super one and Bestek are popular for compact and lightweight sizes. It fits in easily anywhere in the car. If you like traveling for weekend trips, then you can purchase this for charging batteries on the go.

#4 Power Storage Capacity

Power inverters have great storage capacity, and they can store up power and deliver at a steady pace to the connected devices. While buying the power inverter, check the continuous power supply and peak power of the inverter.

For instance, Krieger is a heavy-duty inverter with a 4000W continuous power supply to 8000w peak power. Some inverters can provide peak power in few minutes like Energizer can peak the power in a couple of minutes.

The more power it generates, the higher appliance you can connect. For instance, if you are traveling into the woods with an RV, Krieger is the best. 

#5 Power Quality

Power quality is the stability of the power in the voltage and harmonics. The power supply has a harsh wave through its AC power. This causes excessive jerking and buzzing sound in the inverter.

The products mentioned in the article do not jerk and do not produce a buzzing sound. It maintains the power and so the circuit in the control board does not burns out.
