When identifying a portable generator, there are several reasons you might need a large one. High-power needs like providing home backup during power outages, powering multiple tools on a construction site, running food trucks or coffee vans, or sustaining outdoor events or industrial machinery are common examples. However, figuring out the right size that isn’t too loud and fits your budget can be challenging.
Today, we’ll be comparing two models, the DeWalt DXIG3600E and Yamaha EF3000iSE. Our comparison will focus on specs and features like performance, power, fuel type, runtime, physical dimensions, outlets available and noise level.
Performance & Power
Running Power (W): DeWalt DXIG3600E provides a continuous power of 3200W whereas the Yamaha EF3000iSE offers 3000W. While this difference might seem small – around 6% more power in the DeWalt – it can be significant if you’re running close to the unit’s max capacity. This amount of power allows both generators to run appliances like water heaters or an industrial vacuum.
Starting Power (W): With starting powers of 3600W for the DeWalt and 4000W for the Yamaha. The higher ‘burst’ of power on the Yamaha may make it more suitable for items that require more juice to start up.
Engine type: Both models feature OHV (Overhead Valve) engines which are generally better in terms of fuel efficiency, engine lifespan and improved power output. However, at 121cc, DeWalt’s engine is significantly smaller than Yamaha’s 171cc engine.
Rated Output (kVA): The only available data is for the Yamaha EF3000iSE with a rated output of 2.8kVA. This means it can handle a higher apparent power, beneficial for equipment that pulls more current.
Inverter: Both DeWalt DXIG3600E and Yamaha EF3000iSE feature inverter technology, ensuring cleaner power output which is essential for sensitive electronic devices.
Fuel & Run Time
Fuel Type: Both generators run on petrol.
Fuel Tank Capacity: The Yamaha holds noticeably more fuel than the DeWalt (13L vs 9L). A larger tank should typically provide a longer runtime between refills.
Run Time: The Yamaha’s significantly longer runtime (20.5 hours at 1/4 load) compared to the DeWalt’s 8 hours, is most likely down to its larger fuel tank and potentially enhanced fuel efficiency.
Dry Weight: At 67kg, the Yamaha is significantly heavier than the lighter 43kg DeWalt. Heavier models bring stability but compromise portability.
Size: Yamaha’s larger dimensions (68.0 x 44.5 x 55.5 cm) suggest it will take up more space compared to the smaller DeWalt (64 x 39 x 45 cm).
Wheels: Wheels on both generators ease movement despite their weight differences.
Outlets & Parallel Use
AC Outlets: Both models offer two AC outlets letting you power multiple devices simultaneously.
DC Outlets: While both models provide DC outlets, only DeWalt features dual USB ports for charging smaller appliances or devices.
Parallel Use: No information available whether DeWalt allows parallel use; however, Yamaha does not support this functionality.
Features & Usability
Compared features of these generators reveal some key differences:
- Both have a fuel gauge (LED Indicator on DeWalt and unspecified type on Yamaha), oil alert systems, and are air-cooled.
- Only DeWalt DXIG3600E offers LED power indicators.
- While DeWalt DXIG3600E features a low oil auto shut-off safety feature, no safety details are provided for the Yamaha EF3000iSE.
- Yamaha EF3000iSE features a brushless alternator and a spark arrestor.
Comparing noise levels, the DeWalt DXIG3600E (63 dBA) is noticeably louder than the Yamaha EF3000iSE (51 dBA). The sound of a normal conversation is typically around 60-70 dBA. A quieter generator such as the Yamaha would be more suitable for noise-sensitive environments.
