A portable generator can be a lifesaver during power outages, camping trips, or for running tools on a job site that lacks main power. But choosing the right generator can be tricky. It needs to be the right size for your power needs, not too loud, and within your budget.

Today, we’re comparing two popular models: the DeWalt DXIG2200 and the Yamaha EF1000iS. These models have unique selling points; DeWalt DXIG2200 focuses on easy transport and an ECO throttle, while the Yamaha EF1000iS boasts about being quiet with a small lightweight design and long run time. We’ll examine their performance, fuel efficiency, physical specs and more to help you decide which one is best for you.

Performance & Power

Running Power (W): The DeWalt DXIG2200 offers 1800 running watts, sufficient to power a space heater (1500 W) or an electric grill (1650 W). On the other hand, Yamaha’s EF1000iS provides 1000 watts that could easily run a kettle or belt sander each requiring 1000W. Here, the DeWalt has an upper hand with higher continuous power offering.

Starting Power (W): When dealing with starting power DeWalt can generate a peak of 2200 watts while Yamaha produces 1600 watts. This difference in starting power might be significant when operating devices that require an initial burst of energy.

Engine type: Both generators use OHV engines; however, DeWalt DXIG2200 has a larger engine at 79cc compared to Yamaha’s 50cc engine. This signifies that they offer impressive power output and durability.

The Rated Output (kVA) of Yamaha EF1000iS is 0.9. DeWalt’s kVA is not specified, making a comparison challenging.

Inverter: Both generators boast inverter technology, offering clean power essential for delicate electronics like laptops, and they are both generally quieter and more fuel-efficient.

Fuel & Run Time

Fuel Type: Both generators run on petrol, which is universally available and yields a good balance of cost-efficiency and performance.

Fuel Tank Capacity: DeWalt DXIG2200 carries more fuel with a 4.5L tank compared to Yamaha EF1000iS’s 2.5L tank. This larger tank would mean fewer refills but might add weight to the unit.

Run Time: Despite having a smaller fuel tank, the Yamaha EF1000iS offers longer run time of up to 12 hours at quarter load while DeWalt DXIG2200 runs for 8 hours at the same load. This could mean fewer interruptions for fuel refills with Yamaha.

Physical Specs

Both generators lack wheels for mobility. However, differences exist in their weight and size:

Dry Weight: Weighing only12.7kg the Yamaha EF1000iS is significantly lighter than the DeWalt DXIG2200 which weighs 21.9kg.

Size: The DeWalt is larger (51 x 45 x 30 cm) compared to the Yamaha (45 x 24 x 38 cm). This size difference could impact storage and transport options depending on your available space.

Outlets & Parallel Use

Both models offer one AC outlet for alternating current devices; however, when it comes to DC outlets that can power batteries and small appliances, there are differences:

DC Outlets: The DeWalt features a dual USB outlet while the Yamaha only has one 12V outlet. Having more DC connections provides more flexibilityl as you can charge multiple devices simultaneously. Unfortunately, Yamaha doesn’t offer parallel use, whereas it is not specified for DeWalt.

Features & Usability

Both generators have a manual recoil starter system and an oil alert feature. The DeWalt DXIG2200 features an LED indicator for fuel and power and a safety feature of auto shut-off for low oil. The availability of brushless alternators
and spark arrestors in Yamaha EF1000iS makes it more efficient and safe to operate.

Noise Level

The DeWalt DXIG2200 operates at 55 dBA which is equivalent to the noise level of a refrigerator, whereas Yamaha EF1000iS is quieter, producing only 47 dBA almost like the sound of a quiet home.
