This Champion 6250W DH is a hybrid that combines the power of the conventional with the efficiency of inverter generators. It can support up to 1 ½ HP well pumps with its 5000W running and 6250W peak power capacity.
What I like about this and other inverter generators is that it’s capable of throttling the engine when it’s not at 100% capacity. This helps you save a lot more on fuel costs specially in the long run.
- Pros
- Highly efficient inverter type helps save fuel
- 13.5 hours between refill
- Quieter than others in its range
- Great build quality
- Cons
- Needs more initial investment than conventional types
Best value for larger pumps
- Key Features
- Running capacity: 7500W
- Starting capacity: 9500W
- Est. run time: 11 hours at 50%
- Tank capacity & fuel type: 6.6 gal. gasoline

- Starter: Electric with remote key fob, recoil
- Weight: 192 lbs.
- Warranty: 3 years
- Outlets: GFCI 5-20R 120V Household Duplex Receptacle (2) and L14-30R 120/240V Twist-Lock Receptacle
This Westinghouse portable generator is the best you can get for larger well pumps. It’s a 7500W gasoline generator with 9500W of peak capacity.
Although it doesn’t have dual fuel capability, this generator makes up for it with a slight boost in efficiency. It can run up to 11 hours at 50% load. Giving you more time between refills.
My favorite part about it though is that aside from having an electric starter, it also comes with a remote key fob. That’s some sweet icing on top of this great generator.
- Pros
- Great fuel economy
- Has an electric start and remote control
- Rugged construction
- Cons
- A bit noisy
Best dual fuel for larger pumps
- Key Features
- Running capacity: 7500W (G); 6750W (P)
- Starting capacity: 9375W (G); 8400 (P)
- Est. run time: 8 hours (G); 5.5 hours (P) at 50%
- Tank capacity & fuel type: 6.0 gal. gasoline & propane
- Noise level: 74 dBA
- Starter: Electric, recoil
- Weight: 200.6 lbs.
- Warranty: 3 years
- Outlets: 120/240V 30A Locking (L14-30R), 120V 30A Locking (L5-30R), GFCI 120V 20A Duplex (5-20R) (2)
If you want both power and flexibility, this Champion Dual Fuel generator is the best you can get. It’s rated for 7500W on gas and 6750W on propane with peak capacity each at around 25% above that.
Unlike the DH series, this is a conventional type generator. This means that even though it makes more noise and uses more fuel it would have been a lot cheaper if it weren’t for all the added features. Like the electric start for the engine which is definitely nice.
Unfortunately, it seems that the outlets are uncovered. Although that’s definitely an easy fix if you have to.
All in all, its price, adaptability, and performance more than make up for it. This is a great portable generator for well pumps nearing the 3 HP range.
- Pros
- Dual fuel capabilty
- Has an electric starter
- Great build quality
- Cons
- Outlets aren't covered
The best for whole home supply
- Key Features
- Running capacity: 9000W (G); 8000W (P)
- Starting capacity: 12000W (G); 10800 (P)
- Est. run time: 8.5 hours (G)
- Tank capacity & fuel type:6.6 gal. gasoline & propane
- Noise level: 69 dBA
- Starter: Electric, recoil
- Weight: 242 lbs.
- Warranty: 2 years warranty
- Outlets: 14-50R/50A/125V-250V L5-30R/30A/125A
- Also comes with 25' extension cord
When you have a more powerful well pump, you need a generator that can match it. This A-iPower dual fuel generator is rated for up to 9000W (12000W peak) with gasoline and 8500W (10800w peak) with propane. Giving you enough wiggle room for your pump and other equipment.
It’s equipped with a 50A receptacle for a much larger current capacity. It even comes with a 25 feet extension cord as a bonus.
The only drawback is that it only has 2 years of warranty compared to the 3 years from others. Although I think you could trust A-iPower’s quality, the extra year would’ve been nice.
If you can live with that, I’m sure this generator will make you happy.
- Pros
- Dual fuel capability
- Electric starter
- High capacity for powering up more appliances
- Great price point
- Cons
- Warranty is only 2 years
