5 Best generators for mobile detailing reviews
People who know more or less how much power they need could make a choice with the list of top picks and performance table.
That being said, you will likely find it easier to find the best generators for your mobile detailing operation after checking out the reviews below.
1. WEN 56380i 3800 – Best generator for mobile detailing
The WEN 56380i 3800 does get the top pick for the best generator for mobile detailing but your power needs will influence your choice.
With 3800 starting watts and 3400 running watts, you should be able to run two smaller tools like a vacuum and steamer or a medium tool like an air compressor.
If this is the right power range for you, the WEN 56380i 3800 is a great option thanks to its combination of solid features and a reasonable price.
For example, with the good run time of 8.5 hours at 50% load, you should be able to complete your mobile detailing sessions without too many obligated refuel breaks.
Pros
- WEN 56380i 3800 offers 3800 starting watts, 3400 running watts, 30 amps, and 120 volts
- Parallel capability
- Relatively low noise levels of 57 dBA
- Good run time of 8.5 hours at 50% load
- Less than 1.2% THD
- Electric start
- Weight of 99.2 lb (45 kg)
- Relatively positive customer reviews
- 2 years limited residential and 90 days limited commercial warranties
- A lot of customers
- Budget-friendly
Cons
- Relatively short commercial warranty
Additionally, the 1.2% THD is low enough for any sensitive mobile detailing tools you might have.
The noise levels of 57 dBA (at 25% load and 23 feet away) and 90 days commercial warranty are not ideal.
However, as the many happy customers can confirm, the WEN 56380i 3800 is still a relatively quiet portable generator and will often last a nice amount of time.
In short, unless you have you really like the unique details of the next Westinghouse iGen4500DF, you will generally find the WEN 56380i 3800 a good investment.
| Brand Model | Power Capacity | Run Time | Quiet Operation | THD | Reliability Reputation | Fuel Efficiency | Ease Of Use | Portability | Price Category | Current Price |
|---|---|---|---|---|---|---|---|---|---|---|
| WEN 56380i 3800 | 6.5 | 9 | 8.5 | <1.2% | 9 | 9 | 8 | 8 | $ | Check Price |
2. Westinghouse iGen4500DF – Best quiet generator for mobile detailing
The Westinghouse iGen4500DF has two main unique aspects that could make it worth the investment for your mobile detailing operation.
First of all, it is the best quiet generator for mobile detailing with its noise levels of 52 dBA.
If you know that a regular conversation is about 60 dB, it becomes clear that these low noise levels can really make a work day of 8 hours a lot more pleasant for you and the people around you.
Secondly, the Westinghouse iGen4500DF has a dual fuel feature which means it can also run on propane (LPG).
Pros
- Westinghouse iGen4500DF offers 4500 starting watts, 3700 running watts, 30 amps, and 120 volts (gasoline)
- Parallel capability
- Dual fuel means generator can run on propane too
- Best quiet generator for mobile detailing with noise levels of 52 dBA
- Long run time of 18 hours at 25% load
- Less than 3% THD
- A lot of performance tracking metrics
- Optional CO sensor
- Weight of 104.7 lbs (47.5 kg)
- Relatively positive customer reviews
- 3 years limited residential and 1 year limited commercial warranties
- A lot of customers
Cons
- Some customers find changing the oil challenging
If you are working on mobile detailing, you will likely not get in a situation where gasoline is not available.
However, if you will only use your generator occasionally, using the propane function instead allows you to avoid gummed carburetors.
If you do plan to use gasoline, the run time of 18 hours at 25% load can be a welcome detail.
This allows you to focus more on actually using this generator for running pressure washers, vacuuming, steaming, or whatever other services you offer.
The full one year commercial warranty could also put your mind just a bit more at ease if the relatively positive Westinghouse iGen4500DF reviews did not do so already.
| Brand Model | Power Capacity | Run Time | Quiet Operation | THD | Reliability Reputation | Fuel Efficiency | Ease Of Use | Portability | Price Category | Current Price |
|---|---|---|---|---|---|---|---|---|---|---|
| Westinghouse iGen4500DF | 7 | 9.5 | 9 | <3% | 8.5 | 8.5 | 8 | 8 | $$ | Check Price |
3. WEN 56225i 2250 – Best small
The generators above are great but you may find them a bit too big and pricey for your current mobile detailing operation.
If that is the case, you could also consider starting with smaller models like this WEN 56225i 2250 although you want to make sure you don’t expect too much either.
More specifically, the 2250 starting watts, 1800 running watts, and 15 amps can be enough to run a smaller vacuum, steamer, or potentially pressure washer.
However, if you want to run multiple of these, you can only keep one device turned on at a time.
Pros
- WEN 56225i offers 2250 starting watts, 1800 running watts, 15 amps, and 120 volts
- Parallel capability
- Relatively low noise levels of 53 dBA
- Nice run time of 6 hours at 50% load
- Less than 1.2% THD
- Light weight of 48.5 lb (22 kg)
- Relatively positive customer reviews
- 2 years limited residential and 90 days limited commercial warranties
- A lot of customers
- Budget-friendly
Cons
- Relatively short commercial warranty
- Uses a lot of oil
Something more specific to the WEN 56225i 2250 is that the commercial warranty is relatively short at 90 days.
A more positive point is that you should have no problem taking the 48.5-pound (22 kg) WEN 56225i 2250 out of the car and moving it around.
The 53 dBA should also not disturb your ears of you and any nearby clients too much.
More serious mobile detailing operations likely want to go for one of the stronger generators on the list.
However, the WEN 56225i 2250 could be a good first step to figuring out how much you would actually benefit from a generator during your services.
| Brand Model | Power Capacity | Run Time | Quiet Operation | THD | Reliability Reputation | Fuel Efficiency | Ease Of Use | Portability | Price Category | Current Price |
|---|---|---|---|---|---|---|---|---|---|---|
| WEN 56225i 2250 | 5.5 | 8 | 9 | <1.2% | 9 | 7.5 | 7 | 9.5 | $ | Check Price |
4. Champion 100519 6250 – Best large
Even the more above-average generators above could still be lacking for the tool combinations that would make your mobile detailing sessions faster and more convenient.
For not that much of a bigger investment, the Champion 100519 6250 could be strong enough to offer this extra power with its 6250 peak and 5000 running watts.
While the sizes of your tools matter, this could theoretically run a reasonably sized air compressor, vacuum, and steamer at once.
One thing you do want to keep in mind is that the noise levels of 69 dBA are somewhat louder compared to the other best generators for mobile detailing.
Pros
- Champion 100519 6250 offers 6250 starting watts, 5000 running watts, 30 amps, and 240 volts
- Nice run time of 13.5 hours at 25% load
- Less than 3% THD
- Weight of 121 lb (54.9 kg)
- Relatively positive customer reviews
- 3 years limited residential and 270 days limited commercial warranties
- A lot of customers
Cons
- Noise levels of 69 dBA are somewhat louder
- Oil change is somewhat inconvenient
- No parallel capability
- Fuel efficiency is not that good
In locations where you don’t have the ability to put the portable generator really far away, these noise levels could be disturbing to you, your colleagues, and your clients.
Changing the oil of the Champion 100519 6250 is also somewhat inconvenient although this should not be the end of the world for a mobile car detailing service.
That being said, the Champion 100519 6250 definitely still deserves a spot on this list.
At this price point, the nice run time, good reliability, and nice warranties really stand out positively.
| Brand Model | Power Capacity | Run Time | Quiet Operation | THD | Reliability Reputation | Fuel Efficiency | Ease Of Use | Portability | Price Category | Current Price |
|---|---|---|---|---|---|---|---|---|---|---|
| Champion 100519 6250 | 8 | 8.5 | 5.5 | <3% | 9 | 7 | 8 | 7.5 | $$ | Check Price |
5. Champion 201067 9000 – Best very large
Mobile detailing businesses that really have a few employees and the matching tool amounts and sizes could consider investing in large inverters like the Champion 201067 9000.
This model appears in many best generator selections for good reasons.
First of all, it will be hard to find other portable generators that offer this much “clean” low THD power at a reasonable price like this.
Additionally, the good reliability reputation can be a valuable investment for mobile detailing businesses that are in it for the long term.
Pros
- Champion 201067 9000 offers 9000 starting watts, 7250 running watts, 50 amps, and 240 volts
- Run time of 10.5 hours at 25% load
- Less than 3% THD
- Electric start
- CO sensor
- Four GFCI outlets
- Weight of 152.2 lb (69 kg)
- Relatively positive customer reviews
- 3 years limited residential and 270 days limited commercial warranties
- A lot of customers
Cons
- Run time is not the most impressive compared to other mobile detailing generators
- Not everyone will need this much power for mobile detailing
- Noise levels of 72 dBA are somewhat louder
One thing you do want to keep in mind is the somewhat shorter run time of 10.5 hours at 25% load.
On a busy day, you may need to interrupt your services to refuel the generator a good number of times.
Additionally, the noise levels of 72 dBA are on the louder side which can become annoying. Especially during a long work day.
These downsides need to be noted but at the same time, the Champion 201067 9000 is still the best very large generator for mobile detailing.
If you need around 9000 starting watts, 7250 running watts, and/or 240 volts, this is likely the right choice for you.
| Brand Model | Power Capacity | Run Time | Quiet Operation | THD | Reliability Reputation | Fuel Efficiency | Ease Of Use | Portability | Price Category | Current Price |
|---|---|---|---|---|---|---|---|---|---|---|
| Champion 201067 9000 | 9.5 | 7.5 | 5 | <3% | 9 | 8 | 8 | 7 | $$$ | Check Price |
Popular mobile detailing generators that did not make the list
There are two popular generators that often make it to lists of the best models for mobile detailing but not this one.
More specifically, I did not include the Honda EU2200i and Honda EU7000iS in the list of top picks. Mainly because of their high prices.
Honda generators can be worth the higher investments if you really need reliability, durability, and silent operation.
While these things would be somewhat helpful for mobile detailing too, I assume most people will not value these things enough to justify the big price jumps.
FAQ
What is a good size generator for mobile detailing?
If you don’t mind switching between smaller tools, a 2200 peak watt generator could be good enough for mobile detailing.
To run two smaller tools or one medium tool during your mobile detailing sessions, you want to turn to a 3800 or even 4500 peak watt generator.
If you have a somewhat bigger two-man operation, a generator of around 6000 to 7000 peak watts may be necessary to run two medium-sized tools and slightly more.
Lastly, for bigger mobile detailing businesses, something like 9000 peak watts or even a bigger size generator could be worth the investment.
What size generator do I need to run a car detailing vacuum?
To run a car detailing vacuum you generally want at least around 1000 to 1400 running watts which means you need a 2000 peak watt generator and preferably even bigger sizes.
Our top pick
The WEN 56380i 3800 gets the top spot for the best generator for mobile detailing. At least if you want just enough capacity to run two small or one medium tool.
If you only want to run one small tool at a time, the WEN 56225i 2250 can be good enough and save you some money.
For bigger mobile detailing operations, you likely want to go in the direction of the Champion 100519 6250 or even a bigger generator.
