Portable generators are incredibly helpful when you’re on the go and need an external power source. Maybe you’re camping, out on a day trip, or encountering a power outage at home. Whatever the situation might be, having access to power can be a game changer. Choosing the right generator, however, can be tricky. You’ve to consider size, noise level, and of course price. Today we are comparing two products: The Hyundai HY2000Si and the Yamaha EF2200iS inverter generators.

Both of these models offer several key selling points according to their brands. Hyundai markets its HY2000Si as quiet, reliable, efficient with an ECO mode that allows running sensitive equipment. On the other hand, Yamaha’s EF2200iS boasts about an extra 200 watts of power in a compact package that is lighter and smaller than its predecessor model, the EF2400iS. We’ll be comparing specific features like performance & power, fuel capacity & run time, physical specifications and extra features to guide you in making the best choice.

Performance & Power

Running Power (W):
With 2000 watts running power, Hyundai HY2000Si is robust enough for several applications including off-grid solar systems as well as professional usage. The Yamaha EF2200iS offers slightly more punch with 2200 watts running power – letting you run bigger devices like air conditioners.

Starting Power (W):
Both these units have different starting powers with Hyundai offering a continuing stable output of 2000W while Yamaha peaks at 2300W before settling down to its running wattage. This helps when starting motor driven appliances which demand an initial surge of power.

Engine Type:
They both use OHV engines which is overhead valve technology known for its efficiency and longevity. The Hyundai has an 80cc engine while Yamaha’s is marginally smaller at 79cc.

Rated Output (kVA):
This number reflects the overall power output. Here, the Hyundai leads with a rated output of 2kVA as compared to Yamaha’s 1.8kVA. While it might not seem much of a difference, this could potentially affect how you use your generator.

Both generators come with inverter technology which ensures the power output is smooth and stable – essential for powering sensitive devices like laptops, televisions or mobile phones.

Fuel & Run Time

Fuel Type:
Both models run on petrol so no major differences there.

Fuel Tank Capacity:
Here, the Yamaha EF2200iS pulls ahead with a larger fuel tank – 4.7 litres as opposed to Hyundai’s 3.8 litres which means less frequent refills.

Run Time:
The slight edge in fuel capacity and efficient design allows Yamaha to run longer on a tank of fuel – an impressive 10.5 hours at a quarter load compared to up to 8 hours from the Hyundai model.

Physical Specs

Dry Weight:
The lighter weight of the Hyundai HY2000Si at 21kg against Yamaha’s 25kg makes it easier to manoeuvre around and transport.

When it comes to size, the Yamaha again pulls ahead being more compact than the Hyundai generator, perfect for situations where storage space is a premium.

Information about wheels isn’t given for either generator so we won’t delve into that here.

Outlets & Parallel Use

AC Outlets:
Both products feature two AC outlets letting you power multiple devices simultaneously.

DC Outlets:
They both feature a single DC outlet but missing details on Hyundai’s DC outlet specifications doesn’t allow me to delve further here.

Parallel Use:
The ability to connect two generators to double your power output is only stated in the case of Yamaha EF2200iS. A potentially useful feature for larger power demands.

Features & Usability

In terms of features, both products showcase a recoil start system – a tried and tested manual method of starting the generator. They differ mainly in their indicator systems and safety features. The Hyundai model provides overload protection and a digital display while no specific indicators are mentioned for the Yamaha model. Although, Yamaha adds an oil alert system, brushed alternator and spark arrestor not specified in Hyundai’s data.

Noise Level

Noise Level:
Both generators are remarkably quiet in operations with the Hyundai HY2000Si operating at 58 dBA which is just slightly louder than the 57 dBA from the Yamaha EF2200iS. To put it into perspective, this noise level is less than that of a average conversation, making both models suitable for campgrounds, picnics or any settings where noise is a concern.

When looking at all aspects combined, the decision rests on what you deem most important. The Yamaha EF2200iS offers extra power and run time with a compact design – an ideal option for those needing extended operation time and higher power capacity without worrying about storage space. On the other hand, if you’re looking for overall efficiency combined with lighter weight, then the Hyundai HY2000Si might be just right for you.
