Choosing a large portable generator can be challenging. But why would you need such a generator? They serve high-power needs like powering your home during outage periods, running multiple tools on construction sites, supporting food trucks or outdoor events, or even powering industrial machinery.
Today we’re looking at two models: the Honda EU70is and the Hyundai HY6500SEi. The Honda is touted as a high output, fuel-efficient machine while Hyundai claims theirs provides high performance and works well for professionals or as back-up for off-grid solar systems.
We will compare these models on various factors – running power, engine type, fuel capacity and run-time amongst others – to help you make an informed choice.
Performance & Power
Running Power (W):
A generator’s running power is important; it’s the continuous power provided by the machine.
The Honda EU70is offers 5500W of running power while the Hyundai HY6500SEi provides 6500W. You could use either of these generators to power large electric tools like water heaters or welders.
Starting Power (W):
The starting power is the generator’s peak wattage that is used when devices start; the Honda offers 7000W and Hyundai stands with its 6500W running power.
Look at the engine size and type as they play an important part in overall performance. Both generators have a ‘Overhead Valve’ (OHV), 390 cc, 4-stroke engine – providing smooth operation with better fuel efficiency and improved power output.
Rated Output (kVA):
The apparent power of a generator is measured in kVA. The Honda has a rated output of 5.5 kVA and the Hyundai has a larger rated output of 6.5 kVA.
Both generators feature inverter technology, ensuring cleaner power output suitable for sensitive electronics.
Fuel & Run Time
Both machines utilise petrol.
Fuel Tank Capacity:
More fuel means longer running times. The Honda’s fuel tank can hold 19.2L, while the Hyundai holds slightly less at 18.5L.
Possessing an impressive run time of up to 18 hours at ¼ load, the Honda drastically reduces the need for frequent refuelling.
The weight of a generator can affect its portability. The Honda weighs 118kg compared to Hyundai which stands lighter at 89kg.
The dimensions of the generator will determine how much space it occupies. The Hyundai is slightly smaller than the Honda and would be easier to transport and store.
For easy movement, the Honda comes with wheels.
Outlets & Parallel Use
The Honda has 3 AC outlets while Hyundai offers two 15Amp and one 32Amp AC outlets.
Unlike the Honda, the Hyundai includes two DC outlets – one is a 12V and other is a 5V outlet.
No data was available about parallel use for either model.
Features & Usability
The generators provide different starting systems: Honda offers both electric and recoil start system while Hyundai provides four types including electric, recoil, remote and auto start. A fuel gauge and oil alert system can be found in only the Honda model whilst indicators are present in both models. Only Hyundai lists specific accessories.
The noise level of these generators varies quite drastically; running at a quarter load, a Hyundai operates at around 65 dB which is around the level of a normal conversation. On the other hand, Honda registers at 90 dB, which is about as loud as a chainsaw.

Both generators can cater to higher power demands. The Honda EU70is might be better for those who need longer run times and do not mind the larger size and weight. On the other hand, the Hyundai HY6500SEi could be a better choice if you’re after smaller, lighter and quieter backup power supply.
