Best Power Inverter for Truck Reviews

The best power inverter for trucks is the Voltworks VS-3000QBR. It provides 3000W of continuous power, and also produce pure sine waves that help protect your electronics.

Below you’ll find a list of the best inverters for trucks available on today’s market. However, before exploring them in detail, it’s necessary to understand the difference between pure sine wave and modified sine wave models – they are 2 main types of inverters.

  • Pure sine inverters are ideal for delicate equipment like medical instruments, new TVs, fridges, and microwaves with AC engines, etc. Such inverters provide consistent, clean, and light energy that allows your electronics to run smoothly. However, these models have one disadvantage: they are more expensive than modified versions.
  • Modified sine inverters produce an AC signal that is pretty similar to a genuine sine wave. Furthermore, they may quickly change polarity from positive to negative, causing interference and damage to devices with sensitive elements. On the other hand, modified sine inverters are more cost-effective and function well with basic tools like chargers, laptops, pumps, motors, etc.

How to choose the right inverter for trucks?

What size power inverter do I need for a truck?

Before shopping around for an inverter, determine your goal and how you’re going to use this device. For instance, if you plan only to charge your phone in your truck occasionally, you may buy a smaller size inverter with a 12-volt adaptor. However, if you want to use it for more demanding tasks, you should pick a more powerful model.

To determine the necessary size of your inverter, follow these steps:

  • Add up the wattage of all devices you’re going to run
  • Add 20-30% of the total wattage
  • The inverter size should be rounded up to the next size, e.g., if your total exceeds 1600 watts, purchase a 2000-watt unit.

Required connections and remote control capability

Consider how many devices you plan to hook up to your inverter. Typically, inverters include USB connectors as well as AC outlets, allowing you to power your laptop and phone simultaneously. The number of ports required is determined by the number of gadgets you have. More ports imply a higher-priced inverter with a larger AC power.

Safety certification

A great power inverter for truck drivers must be certified and meet all industry standards. So, what certifications should you look for?

In the United States, the ELT, UL, and FCC seals all signify that the unit meets all electrical and durability criteria. While these certificates aren’t required by law, having one on your inverter will give you extra protection and peace of mind.


How many batteries do you need for a 3000-watt inverter?

That depends on the type of battery. In general, they should be deep cycle batteries, not a car or marine batteries. In most cases, you will need more than one battery for a 3000-watt inverter. For example, four 100 amp hour Deep Cycle Batteries would be what you are looking for if you need to run your entire house for a week.

How long will a car battery power an inverter?

It depends on the inverter, but it will not last very long at all. Also, note that a large inverter may require a deep cycle battery or even two batteries.

Car batteries are not meant to be discharged below about 50% regularly. They are only designed to provide bursts of high current, followed by the shallow current until they can recharge again. A deep cycle battery, however, is designed to discharge between 20-50% regularly.

What inverter do truckers use?

It depends on the trucker. Some use the simple cigarette lighter inverters, some spend a little more for an inverter that is also a radio and phone charger, and others may go with the biggest one they can find, including air conditioning or even satellite internet.

Will an inverter drain my semi-truck battery?

An inverter will not drain your battery if it is completely disconnected from the truck (meaning there is no power coming in). It will only draw current if it has a load on it like an appliance.

What gauge wire do I need for my inverter?

This depends on how much power you need. For example, a 1000 watt inverter would require about 10-12 gauge wire. An inverter that is twice as powerful would require 20-22 gauge wire, and an inverter that is four times as powerful would require 14-16 gauge wire.

Where do you put an inverter in a truck?

An inverter can be located anywhere in the cab of the truck. Most often, it is placed in a space near where it will be used (the front seat, underneath the bunk, etc.). Many inverters are designed with heat sinks to assist in keeping them cool, so placing them in an area with airflow is essential.

What are the most reliable power inverters for trucks?

This depends on your application. For example, if you are looking for a power inverter that is reliable to run an electric blanket, then the most reliable would be one of the small cigarette lighter style inverters. On the other hand, if you are looking for a power inverter that can support all of your truck appliances at once, then several larger hardwired inverters are very reliable.
