Generators for Car Detailing

If you’re a mobile vehicle detailer, you’ve probably encountered instances when you couldn’t utilize the client’s power source. Generators are used in this situation. But, you might be wondering, “What generators for car detailing?

In short, the 3000 Watt inverter generator is the best option for most detailers. This will provide adequate power for all of the tools you’ll need to detail autos.

Should You Buy Generators for Car Detailing?

You’ll need a generator if you’re pumping water, powering polishers, or running a medium to large detailing business. Remember that a good generator is not inexpensive. If you’re just starting off, you might not want to invest $700-$2000 unless it’s essential. If you’re visiting a customer’s home and have access to water and electricity, extension cords and hoses are probably more cost-effective.

However, employing a generator for car detailing has significant benefits, such as powering vacuums and pumps, pressure washers, and everything else a mobile detailing equipment needs.

The first step is to list all the equipment that requires power. This will assist you in determining which generator is appropriate for your company. The 3000 Watt inverter generator is, on average, the best option.

Basic Terms to Understand the Generators

Before we get started, there are a few things you should know. This can significantly assist you in selecting the appropriate size generator for your vehicle detailing business.

What you should know:

  • Continuous power is the number of watts that an inverter generator can continuously distribute. It’s recommended to choose a generator with at least somewhat more continuous power than the gadget you’ll be using it with.
  • Maximum or peak power is the maximum number of watts that an inverter generator can produce in a short time. It’s always a little more than the constant power. It’s significant because some tools have a peak power that exceeds the constant power. Therefore, when you first start up a tool, it usually uses more power.
  • Watts (W) is a power measurement unit. It’s the quantity of energy required for some tools to perform properly.
  • The difference in charge between two places is measured in volts (V). For example, appliances in the United States are typically 110-120 volts, while those in Europe are 220-230 volts.
  • The unit of electric current is the ampere (A).

All of these numbers are given in the description of most gadgets. On occasion, though, you may notice that some tools lack Watts numbers. That is why you must understand how to determine the required wattage for certain electric equipment.

Watts are calculated using the formula Amps * Volts = Watts. So, you’ll need to know the Amps and Voltage figures to determine the required power.

For example, a device with 8A and 120V can be used. 8*120=960 Watts. Alternatively, a 6A 220V gadget. 6*220=1320 Watts.

Generator Types

There are two sorts of generators to consider.

# Inverter generators

Inverter generators are ideal for detailers who want mobility.

Homes often prefer traditional generators since they can become rather large, have large fuel tanks, and run for a long period.

When it comes to detailing, though, you don’t need anything that takes up a lot of room (assuming you don’t already have one). Because you’ll most likely just use the generator for up to an hour at a time, an inverter generator should suffice, especially if you don’t need to pump water or run a lot of tools.

Inverter generator advantages

  • Due to improved mufflers and quieter engines, these run substantially quieter.
  • Portable and light — frequently less than 100 pounds (Honda models are around 47 lbs)
  • Microprocessors and other electronics save fuel by alternating engine speeds.

The disadvantages of inverter generators

  • Beginners should expect to pay upwards of $1,000 for most items.
  • Most larger units have a maximum power output of roughly 4,000 watts, which is insufficient for powering many devices at once.
  • Repairs are more expensive.
  • They are a little more expensive than other generators, which start at approximately $500, but they are well worth the money.

# Standard multifunctional generators

The normal multifunctional generator is the most popular choice I see many detailers employ for trailer setups.

If you have the space, you can’t go wrong with a simple 3500-watt generator unless you’re working out of a van and need the portability.

Advantages of traditional generators

  • Starting price is lower.
  • Muffled capability (still louder than inverted generators, but quieter)
  • Larger fuel tank for equipment power
  • Power ranges from 10,000 to 20,000 watts

The disadvantages of traditional generators

  • Bulky and awkward to store and maneuver (especially in vans)
  • Some people can be quite noisy (a big deal for office parks, etc.)
  • In comparison to inverter generators, they often consume more fuel.
  • For pumping water from a tank, conventional generators are ideal.

If you’re using a pressure washer and can’t utilize the customer’s water supply, having a generator on hand is ideal for generating the pumps required by your water tank.

Unless you buy a belt or gear-driven unit washer instead of a cheaper direct drive, most pressure washers require roughly 20 psi of pressure to work. At a minimum, these pressure washers cost $2,000-$3,000, but they do away with the requirement for a generator to pump water. Just something to think about.

For novices, smaller conventional generators are less expensive to operate.

Most bigger 6,000 watt+ generators can use up to 2.5 gallons of petrol every hour, although smaller generators can use as little as a gallon. So unless you have a lot of equipment to power, I would recommend starting with a smaller generator for beginners.

What Is the Finest Brand of Car Detailing Generator?

I highly recommend Honda generators based on my research and personal experience. Honda is one of the most trustworthy brands of inverter generators available in the detailing industry; news crews and other organizations appreciate them.

If I had to choose, the Honda EU2200i would be my choice based on Amazon evaluations and testimonials, and it simply lasts longer than many others. With a peak power of 2200W, it’s ideal for mobile detailing and small enough to take anyplace.

Because the noise from your generator is practically as quiet as a conversation, you’ll never be bothered by it while it’s running.

Now, let me tell you about the Eco-Throttle system that comes with this generator: depending on how much load the machine has to handle, you get more power and higher fuel efficiency (up to 8 hours of use without charging)

Honda generators are, in general, composed of pure awesomeness. It is one of the most popular mobile detailing generators, and professional detailers and car owners utilize it on a daily basis.


If you’re a mobile vehicle detailer, you’ll need a high-quality and reliable generator. I hope you now have a better idea of what size generator you require for your auto detailing business or hobby. More power is always better, so I suggested you have a 3000 Watt generator. Unfortunately, most auto detailing equipment will only function at half of its potential.

Purchasing a generator is expensive, but it will pay off soon. You’ll be more productive. Electrical cord reels are unnecessary to take along.
