As one of the most essential purchases in your detailing business, a generator is one of the purchases that can truly take your business to the next level.
After doing research and weighing factors like portability, noise level, affordability, and efficiency, I’ll share 5 of the best generators for detailing, followed by a few top picks for detailers on a budget.
My top overall choices
#1: Honda EU2200i 2200-Watt Inverter Generator – Click to View on Amazon

This one tops the list for a few different reasons. The first being that it is one of the most portable on the list, and perfect for the needs of most detailers. The EB line was designed for industrial use, but is pretty similar to the EU line.

#2: Champion 3500-Watt Portable Generator – Click to View on Amazon
This one made by Champion is a solid choice by a reputable generator brand. Marketed as portable, it has a12 hour run time which should last all-day
In terms of affordability, this one is ideal for someone just starting out, since it costs significantly less than others. It can be a little noisy like most in this class, but still a solid option for most beginners.

#3: Champion 2000-watt Inverter Generator – Click to View on Amazon
This particular Champion unit produces 1,600 watts of continuous output, 2,000 maximum and is a great portable option at less than 50 pounds. This one features two 120V outlets and one 12V, and should be enough to power smaller tools (like an orbital buffer). If you are running large compressors or vacs, then you will want something a little larger.
If you need a portable generator, the Champion unit is still smaller than the Honda EU2200, and many say this line (including larger units) gives the industry-standard Honda units a run for their money. It also runs on propane or gas.

#4: Pulsar 3500-Watt Portable Generator – Click to View on Amazon
This portable unit is a great budget option with 3,000 running/3,500 peak watts. This one features two 120V outlets and one 12V, and should be enough to power at least one major appliance, and most tools you will use as a detailer.
In terms of affordability, this one is ideal for someone just starting out, since it costs significantly less than others. It can be a little noisy like most in this class, but still a solid option for most beginners.

#5: Briggs & Stratton 5500-Watt Portable Generator – Click to View on Amazon
This one by Briggs & Stratton is among the most powerful I’m recommending, and ideal for teams of around 2 people that will be simultaneously powering a vac or amp. The B&S brand is known for reliability and serviceability which makes it a good long-term option.
For the power you’re getting, this one is ideal for someone just starting out due to its affordability at less than $1,000. It can be a little noisy like most in this class, but still a solid option for most beginners.

Considerations to keep in mind
There are many factors to consider when purchasing a generator for detailing, but probably the number one factor is the type of equipment you will be powering. If you will be powering large vacuums or compressors, just make sure you have a generator capable of powering it.
If you are on a budget, brand names may not be as big of a deal if you only expect to spend $300 or less, but anything in the $700+ range, I would highly suggest looking into a reputable brand name like Honda, Champion, DuroMax, Pulsar, or Yahama.
Here are some basic considerations to keep in mind before purchasing:
- Run time – Will your generator be on more than 8 hours per day?
- Rated Watts – how many watts to expect when running continuously
- Maximum output watts (surge watts) – Maximum power produced to start certain equipment
- Portability – will you be leaving it in a van/trailer or moving it around?
- Weight – How much weight can your trailer/rig support?
- CARB (California Air Resources Board) or EPA Compliance
- Ability to parallel (link together)
- Fuel type options (gasoline, propane, or natural gas)
- Noise – Do certain office parks/cities have certain noise level ordinances?
Top budget generators to consider for detailing
