DeWalt DXGNI2200
Best OverallPros
- Very quiet operation (52 dB)
- Clean inverter power for electronics
- Compact and easy to carry
Cons
- Not enough power for a large home
- Fuel tank is small (1.1 gal)
The DeWalt DXGNI2200 is a pure sine wave inverter generator that delivers clean, stable power suitable for laptops, phones, and CPAP machines. Owner reviews consistently praise its quiet 52 dB noise level, making it acceptable for camping and neighborhoods with noise restrictions. The parallel capability allows connecting two units for double the output.
Build quality is typical DeWalt with a sturdy frame and reliable Honda-style engine. The runtime is around 8 hours at 25% load, which covers a night of use. It is not designed to run a whole house, but for powering essential appliances and tools, it is a top performer.
Ryobi RYi2300BT
Best BudgetPros
- Very affordable price point
- Lightweight at 39 lbs
- Includes USB ports
Cons
- Not true sine wave (modified sine)
- Louder than premium inverters
The Ryobi RYi2300BT is the best budget portable generator for light duty use. It offers a 2300W peak and 1800W running output, enough for a fridge, lights, and a few tools. Owner reviews highlight its value for money, though some note the modified sine wave output can cause issues with sensitive electronics.
It features a Bluetooth app for monitoring fuel level and runtime, a rare feature at this price. The 1.2 gallon tank provides up to 10 hours of run time at 25% load. For tailgating, camping, or basic home backup, it is a solid, wallet-friendly option.
Milwaukee MX FUEL 3600
Best Job SitePros
- Dual fuel capability
- High output for tools
- Rugged job site build
Cons
- Heavy and not very portable
- High price point
The Milwaukee MX FUEL 3600 is designed for professional contractors who need reliable power on the job site. It runs on gasoline or propane, giving flexibility depending on fuel availability. Owner reviews praise its ability to start heavy tools like compressors and saws without hesitation.
It features a roll cage design and large wheels for transport, though at 105 lbs it is not something you carry by hand. The runtime on propane is about 5 hours at 50% load. It is overkill for home backup but excellent for demanding work environments.
Bosch G4000
Best Home BackupPros
- High running watts for essential circuits
- Low oil shutdown for engine protection
- Bosch brand reliability
Cons
- Heavy and not portable
- No inverter (standard alternator)
The Bosch G4000 is a conventional portable generator built for home backup. With 4000 running watts, it can power a refrigerator, lights, a sump pump, and a few outlets. Owner reviews highlight its reliable Bosch engine and easy electric start. It is not an inverter generator, so power quality is rougher for electronics.
The G4000 features a large 4 gallon tank for up to 13 hours of runtime at half load. It is heavy at 130 lbs and best kept in a garage or shed with a transfer switch. For whole-house essentials during an outage, it offers dependable power at a reasonable price.
Makita EG2200A
Best LightweightPros
- Very lightweight and compact
- Low noise level
- Easy to maintain
Cons
- Limited power output
- Small fuel tank
The Makita EG2200A is a lightweight portable generator ideal for camping, tailgating, or powering a few small tools. It produces 1700 running watts and 2200 peak watts, enough for a fridge, lights, and a radio. Owner reviews appreciate its simple design and easy pull start.
It is not an inverter generator, so power is not perfectly clean for sensitive electronics. The 1.3 gallon tank provides about 7 hours of runtime at half load. For those who prioritize portability and simplicity over raw power, the Makita EG2200A is a reliable choice.
What to check before buying a portable generator
First, determine your power needs. Calculate the running watts of the devices you plan to power and add a 20% safety margin for startup surges. This will tell you the minimum running and peak watts required.
Next, consider fuel type. Gasoline is common and easy to find, but propane offers longer shelf life and cleaner burning. Dual fuel models give you flexibility. Also check runtime at 50% load to ensure it lasts through an outage or work day.
Noise level is important for neighborhoods and campsites. Inverter generators are quieter (50-60 dB) than conventional models (65-75 dB). Portability features like wheels and handles matter if you move the generator often.
Finally, look for safety features like low oil shutdown, circuit breakers, and CO detection. These protect both the generator and your equipment.
Mistakes to avoid
One common mistake is underestimating startup watts. Many appliances like refrigerators and pumps draw 2-3 times their running watts when starting. Always check the peak watt rating of the generator.
Another mistake is backfeeding power through a household outlet. This is dangerous and can kill utility workers. Always use a transfer switch or connect devices directly to the generator.
Do not run a generator indoors or in a garage. Carbon monoxide poisoning is a serious risk. Always place the generator outside at least 20 feet from doors and windows.
Finally, do not overload the generator. Exceeding the running watt rating can damage the generator and connected devices. Use a watt meter to monitor load.
FAQs
What size portable generator do I need for my house?
For essential circuits like fridge, lights, and sump pump, a 4000-5000 watt generator is usually sufficient. For whole house backup, you may need 7500 watts or more.
Is an inverter generator worth the extra cost?
Yes, if you need clean power for sensitive electronics like laptops and phones. Inverter generators are also quieter and more fuel efficient.
Can I run a portable generator in the rain?
No, never run a generator in wet conditions. Use a generator tent or canopy to keep it dry, and always place it on a dry surface.
How often should I change the oil in a portable generator?
Change the oil after the first 20 hours of use, then every 50-100 hours depending on the manufacturer's recommendation.
What is the difference between running watts and peak watts?
Running watts is the continuous power the generator can supply. Peak watts is the surge power needed to start motors and compressors.
Can I connect two portable generators together?
Only if they are designed for parallel operation and you use a parallel kit. This doubles the output while maintaining clean power.
How long does gasoline last in a generator?
Gasoline can degrade in as little as 30 days. Use fuel stabilizer or drain the tank for long term storage.
What is the best fuel for a portable generator?
Propane is best for storage as it does not degrade. Gasoline is more widely available and offers higher energy density.
Do I need a transfer switch for a portable generator?
Yes, for powering hardwired circuits in your home. For plugging in devices directly, you do not need a transfer switch.
How loud is a typical portable generator?
Conventional generators range from 65-75 dB, while inverter generators are quieter at 50-60 dB. Check the decibel rating before buying.
Can a portable generator damage my appliances?
Yes, if the power is not clean (modified sine wave) or if the voltage fluctuates. Use an inverter generator for sensitive electronics.
What is the warranty on a portable generator?
Most brands offer a 2-3 year warranty for residential use. Commercial use often has a shorter warranty period.
