Portable generators are handy devices for various situations that need a lot of power, like dealing with home blackouts, using multiple tools on worksites, and running mobile food vans. However, choosing the right one can be a bit of a challenge. You need to consider several things – size, noise level, and of course, your budget. Today, we’re doing a side-by-side comparison of two inverter generator models – the world-class Engel R3000IE and the high-performing Hyundai HY4000SEi.
Performance & Power
Running Power (W): Engel R3000IE offers 3500W while Hyundai HY4000SEi provides 4000W. These numbers are important as they show how much continuous power each generator can supply. The running watts of any device you connect shouldn’t exceed these values. For example, both generators could easily power a water heater which needs 3000W but only the Hyundai model could run a welder requiring 4000W.
Starting Power (W): Both the Engel R3000IE and Hyundai HY4000SEi have the same starting power as their running power.
Engine type: Engel model uses a 212cc engine while the Hyundai model is powered by a 223cc OHV engine. An OHV (Overhead Valve) engine design usually results in better fuel efficiency and an extended engine lifespan.
Rated Output (kVA): Comparing the apparent power rating shows that the Engel R3000IE stands at 3.5 kVA while Hyundai HY4000SEi offers more with a 5 kVA rating.
Inverter: Both models come with inverter technology for cleaner power output – great news if you’re plugging in sensitive electronics like laptops.
Fuel & Run Time
Fuel Type: Both models use petrol as fuel.
Fuel Tank Capacity: Engel’s model comes with an 8.3L tank and Hyundai’s model has a slightly larger tank of 9L. So, the Hyundai generator might run a bit longer between refills.
Run Time: Engel R3000IE can run for approximately 8.5 hours at 50% load. Unfortunately, run-time information is not available for Hyundai HY4000SEi.
Dry Weight: The Engel generator is lighter at 44.5kg while the Hyundai model weighs in at 55kg. The difference could be important if you’re planning to move it around frequently.
Size: Engel R3000IE measures 59 x 47.8 x 51.1 cm and the Hyundai HY4000SEi is slightly bigger at 60 x 45.2 x 50 cm. Consider where you want to store it or how much space it could consume on your job site.
Wheels: Wheels make transportation easier and that’s one advantage with the Engel R3000IE which comes equipped with wheels.
Outlets & Parallel Use
AC Outlets: Both generators come with two AC outlets.
DC Outlets: Engel R3000IE offers a DC outlet of 12V – 8.3A but Hyundai doesn’t specify this.
Parallel Use: The Engel R3000IE allows for parallel usage where you could connect two of its models to double the power output. However, we don’t have this data available for the Hyundai model.
Features & Usability
The Engel R3000IE uses both a recoil and electric start system while the Hyundai HY4000SEi has three options – recoil, electric or remote, making it a bit more flexible in terms of starting options. Both models have a fuel gauge so you can easily check fuel levels. For safety, the Engel model has an oil alert system but we don’t know if the Hyundai model offers this. The Engel model indicates frequency and voltage while the Hyundai generator provides data through a digital display.
Engel R3000IE operates at 67 dBA and Hyundai HY4000SEi at a quieter 59 dBA. To give you an idea, normal conversation falls around 60-70 dBA while a running vacuum cleaner is about 75 dBA.

Both the Engel R3000IE and Hyundai HY4000SEi portable generators have their merits. Those needing more power might lean towards the Hyundai model, which also offers quite a few user-friendly features such as a larger fuel tank and various start options. On the other hand, if being able to move your generator around easily is important, then the lighter Engel model, with built-in wheels, could be a more suitable choice.
