Your Guide for the Best Truck Inverter for Microwave

Many truckers at present have a power inverter of their own. The best ones have a rating of 1,000 watts of power because it’s capable of powering multiple appliances at the same time at that power level. The most optimum microwave for truck drivers is one ranging from 600 watts to 800 watts.

You can go for a 1-kilowatt model but that means turning off the rest of your other appliances to avoid a power overload. You’ll definitely get electrical issues if you were to buy a microwave with the same wattage.

On that note, what’s the best truck inverter for microwave use?


Buyers Guide on Power Inverters for Microwaves

Every inverter brand might make choosing the right inverter for your intimidating, especially if you’ve never bought one before.

In any case, make sure that the inverter you’re buying has double the wattage of your most powerful device at its peak wattage so that you won’t have to switch between devices to use or unplug your power-hungry appliance when using other units.

What Does a Power Inverter Do?

A power inverter changes direct current (DC) electrical power into alternating current (AC) that’s usable for common devices and appliances. A nice heavy-duty power inverter should be able to deal with the rigors of daily use on the road.

The DC output from the vehicle’s battery is where inverters like the semi-truck power inverter take their energy for conversion into AC power in order to power appliances, equipment, and power tools galore. Nearly all inverters include some sort of fan for cooling purposes.

Thusly, it’s only prudent to mount the inverter in an area of your sleeper or cab that has ample ventilation to assist in cooling it down.

How Powerful Should Your Power Inverter Be?

When choosing an inverter, you should find one powerful enough to run the gamut of appliances you have on hand without overloading your battery. The power output of your power inverter should be enough to run all your devices. Not necessarily at the same time, of course.

  • 2,000 Watts for Big Items: If you’re looking to power big items like microwaves, heaters, mini-fridges, and portable air-conditioners or A/C units, you need a power inverter that can supply you with at least 2,000 watts of power.
  • 300 Watts or So for Small Items: An inverter with a 300 or more watt range is usually enough to power a small color TV or laptop with batteries that last about 5-6 hours until requiring a recharge.

The more components in your truck that require energy the more power you’ll need. Get an inverter not only in accordance to the amount of appliances you have presently but also in light of the appliances you might want to add down the line.

Give yourself and your truck room to grow appliance-wise. Larger power inverters will supply the best power but they require hardwiring or direct connection to your truck, camper, or RV battery. The cigarette lighter port or slot won’t cut it.

What are the Different Wattages of Your Appliances?

Below is a chart full of several common household appliances you might bring with you in your semi-truck, truck, RV, or camper. They include each device’s estimated wattage. In order to see the actual wattage of your make and model of appliance, check the operating instructions or the manual.

If the wattage of your appliance isn’t listed on the doorjamb or manual, you can use a simple formula to calculate the wattage. Multiply the amps to the volts in order to get the watts.

At any rate, here are the estimated watts of the following appliances.

ApplianceEstimated Watts
Air Conditioner2.2 to 5 kilowatts (starting)

1 to 1.5 kilowatts (running)

Toaster0.8 to 1.5 kilowatts
Microwave1.1 to 2 kilowatts
Space Heater1 to 1.5 kilowatts
10-Cup Coffee Pot1.2 kilowatts
Waffle Iron1.2 kilowatts
Hot Plate1.2 kilowatts
Frying Pan1.2 kilowatts
Color TV (25 inches)0.3 kilowatts
Refrigerator or Freezer0.6 kilowatts
Laptop Computer0.05 to 0.075 kilowatts

What is a Watt Anyway?

A watt measures the rate of transfer or how much electricity is required in order to power and operate a device. It’s important because it allows you to figure out how powerful or how much wattage your inverter should have in order to power several appliances at the same time or one by one.

  • Starting Wattage vs. Running Wattage: The amount of wattage put out by your appliances will determine the amount of wattage put out by your inverter. Remember that many devices take double the amount of watts in order to get started compared to when they’re in operation.
  • The Air Conditioner’s Wattage: For example, an A/C is estimated to require 2.2 to 5 kilowatts to start but only 1 to 1.5 kilowatts to run. Therefore, instead of buying a 2-kilowatt truck inverter, you might instead need a 5-kilowatt (or more) inverter instead.

It’s still best to have double the wattage of your peak wattage appliance to run multiple appliances simultaneously. With that said, more wattage doesn’t necessarily mean a better inverter. A more powerful inverter can drain your battery faster.

If you’re parked and your truck is running, this might not be an issue because truck drivers sleep inside their trucks while they’re idling. Otherwise, you need a balance between power and drainage.

Pure Sine Wave (PSW) Vs Modified Sine Wave (MSW)

When undergoing DC to AC current conversion, the power inverter should produce a sine wave. Different inverters showcase different results. Some create the pure sine wave. Others generate a modified sine wave instead.

A pure sine wave (PSW) is the same as the appliances inside a house. This is a stable flow that’s constant and has no variation. You need PSW in sensitive electronics like CPAP machines that require continuous operation.

A modified sine wave (MSW) has more instability to it compared to a PSW. They’re sufficient for usage in inexpensive appliances or low-energy uses like lights. MSW power inverters are less expensive because their flow has more variation to them.

They have many drawbacks though. For example:

  • These inverters tend to overheat.
  • They don’t last as long overall as a PSW inverter.
  • They’re noisy and tend to buzz around (especially the cheaper models).
  • They don’t last for an extended period of time compared to their PSW counterparts.

If you plan to power sensitive devices like PCs and large appliances like microwaves and refrigerators, avoid the MSW power inverter. Their power flow varies too much, thus they could cause damage and shorten the lifespan of your most sensitive appliances.

Even if you have a power strip or surge protector, that won’t be enough to safeguard your device from constant power surges care of the MSW power inverter.

The best power inverter for your semi-truck or truck should be the PSW power inverter. Yes, they’re more expensive but you’re paying for their extra reliability at providing energy that most closely matches what you’d get from your home that’s connected to the power grid.
