Portable generators are handy devices. They can keep your lights on during a power outage, your tools running on a remote worksite, or your appliances working during a camping trip. Choosing can be tricky because you need one that’s the right size for your needs, isn’t too loud, and falls within your budget.

Today we’re checking out two models: The Engel R2000IS and the Yamaha EF2000iS. Engel’s R2000IS is seen as an affordable option with a long warranty and solid service network. On the other hand, Yamaha’s EF2000iS is touted for its quietness, portability, and long runtime. We will compare them based on performance, fuel efficiency, physical specifications, outlets, features, usability, noise level, and more to help you decide which might be great for you.

Performance & Power

Running Power (W): Engel R2000IS vs Yamaha EF2000iS.
Both generators can continuously provide 2000W of power. This means either could power a large air-conditioning unit or table saw which both require around 2000W.

Starting Power (W): Engel R2000IS vs Yamaha EF2000iS
The ability to produce a momentary surge of electricity is where these generators differ. While the Engel’s starting power matches its running power at 2000W, the Yamaha EF2000iS exceeds it with 2300W. This added starting power may help if you have heavy-duty tools or machinery that require that extra burst of power when turned on.

Engine type: Engel R2000IS vs Yamaha EF2000iS.
Both models use four-stroke engines which are known for their reliability and efficient use of fuel. The Yamaha does stand out with its OHV (Overhead Valve) design which leads to better fuel efficiency and improved power output.

Rated Output (kVA): Engel R2000IS vs Yamaha EF2000iS.
The Engel generator has a slightly higher kVA rating of 1.9 compared to the Yamaha’s 1.6 kVa. This means the Engel model can handle appliances that pull more current, like an air conditioner or large refrigerator.

Inverter: Both generators have inverter technology. They can produce cleaner power, suitable for sensitive electronics like laptops.

Fuel & Run Time

Fuel Type: Both models use petrol.

Fuel Tank Capacity: Engel R2000IS vs Yamaha EF2000iS
The Engel generator has a slightly larger fuel tank capacity compared to the Yamaha model (4.8 litres vs 4.4 litres). This minimal difference might not significantly affect how often you need to refill each one.

Run Time: Engel R2000IS vs Yamaha EF2000iS
When it comes to running time, the Yamaha generator outperforms the Engel model. The Yamaha can run for about 10.5 hours at 1/4 load, while the Engel generator runs for about 7 hours at half load and 4.5 hours at full load.

Physical Specs

Dry Weight: Engel R2000IS vs Yamaha EF2000iS
The Yamaha is lighter, weighing in at 20kg as opposed to the Engel’s 22kg weight. The lighter weight could make it easier to transport.

Size: Engel R2000IS vs Yamaha EF2000iS
Yamaha offers a slightly more compact model making it a tiny bit easier for storage and transportation.

Wheels: Neither model comes with wheels.

Outlets & Parallel Use

AC Outlets: Both generators come with one AC outlet.

DC Outlets: Engel R2000IS vs Yamaha EF2000iS
The DC outlets differ. While the Engel generator offers a USB 1A 5V outlet, the Yamaha model comes with a 12V/8A DC outlet. The Yamaha model might be more suitable if you need to charge larger batteries or operate small appliances.

Parallel Use: Yes, both of them allow parallel use. It means you can connect two of the same model to double your power output. However, ensure the required accessories to enable this are included.

Features & Usability

Features: Engel R2000IS vs Yamaha EF2000iS:
Both models have convenient features like a recoil start system and a fuel gauge. However, the Yamaha generator also includes an oil alert system and a brushless alternator for improved efficiency and reduced maintenance. It also contains a spark arrestor for safety.

Noise Level

Noise Level: Engel R2000IS vs Yamaha EF2000iS
The noise level between the models is strikingly different. With a noise rating of 51.5 dBA at 1/4 load, the Yamaha is much quieter than Engel’s 68 dBA at 7m. For reference, normal conversation is around 60-70 dBA.

The Engel R2000IS and Yamaha EF2000iS both make solid contenders for your next portable generator purchase. With their comparable running power, they offer similar capabilities in terms of what appliances or tools they can support.

However, the Yamaha EF2000iS stands out with its longer runtime, lighter weight, slighty compact design and noticeably quieter operation. Also, it offers extra useful features such as an oil alert system and brushless alternator.

On the other hand, if you are operating appliances that pull more current or value a larger fuel capacity then the Engel R2000IS might be a better choice.

Remember, the best generator for you will depend on your specific needs and requirements.
