  • Cell phone charging = 10 watts
  • Electronic logbook = 10 watts
  • Dashboard camera = 5 watts
  • Small television = 100 watts
  • DVD player = 100 watts
  • Toaster oven = 700 watts
  • Microwave oven = 800 watts
  • Refrigerator = 400 watts
  • A/C cooler = 700 watts
  • Heater = 300 watts
  • Laptop computer = 75 watts
  • GPS navigator = 15 watts

The second step is to find out your truck’s compatibility presumably from the truck manufacturer. It is to ascertain the limits to the amount of power that can be drawn using an inverter if any to prevent the blowing up of a fuse while on the road as a result of over-consumption of energy. You may need an approval from your employer for such an installment hence running it through them would be a good idea.

The third step is to consider the safety features. The majority of the power inverter would come with the most common safety features like over and under-voltage protection, short circuit protection, overheat protection, surge protection, etc. If the inverter doesn’t come with these common safety features, you should avoid it.

Ampeak 2000W Power Inverter

ampeak power inverter

With STL and ETL products, Ampeak has become a leading dealer in the automotive industry. This power inverter gives various features to enrich safety. It has a digitalized LED display which shows fault codes, wattage and voltage. Automated shutdown system protects faults issues. It will turn off when your inverter overload, up-down voltage or overheats.

Plus, the audible alarm and cooling fan are paramount when it comes to safety. The cooling fan will cease once the inverter overheats while the alert notifies the critical warnings.

Boost 3000 Watt Inverter

This inverter is one of the most powerful semi-truck inverters on the market. It has an articulate, durable design. It produces 3000-watt continuous output with 6000-watt startup surge. Furthermore, some benefits of this inverter are overload protection, thermal protection, and low battery shutdown. It does not have the UL458 certification.

Xantrex Inverters – PRO Watt Series

Here is another major brand of commercial inverters worth mentioning. They are widely regarded to be the most reliable in the market. It has a slightly lower wattage of 2000. An important thing to note is Xantrex PROwatt inverters do not identify their power inverters by the RMS wattage. They can manage, but they handle slightly less than their model number advertises.

The output frequency of Xantrex PROwatt varies only by .5hz whereas other brands can vary over this number hence its dependability. Another fundamental fact is the inverter operates at 90 percent efficiency while other operate at less. As a result, increased durability and the energy that is not of need exits the inverter as heat.

GoPower 3000-HD

This inverter is a pure sine wave inverter and does not use modified sine waves. Pure sine wave means there is very low harmonic distortion in the electricity supply and the output of power is cleaner, faster, quieter and more relaxed. Perhaps, it is suitable to state this is the best power inverter for semi trucks. It is UL458 certified which is the industry standard certification.

The Occupational Safety and Health Administration approves UL the organization that provides the safety certification. The UL458 standard is designed to protect both the user and the inverter from sudden power surges. It is essential to look at this standardization mark when looking for a power inverter because you want a product that is safe, reliable, and affordable. This same product is available in different watt configurations.


It is clear how important a power inverter is to a trucker and with a wide range of options to choose from, you are almost sure to find what you need. Keep in mind that pure sine wave inverters will be more expensive than modified sine wave inverters and the main difference between them is the level of efficiency. This article should provide you a decent idea of how to go about your search with ease.
