Portable generators are handy tools. They can provide backup power during blackouts, run equipment on construction sites, support outdoor events and even power food trucks. However, finding the right one can be tricky. You need to consider size, noise level and, of course, cost. Here we take a look at two models: the high output and fuel-efficient Honda EU70is and the powerful, user-friendly Yamaha EF6300iSE with an optional remote start.

Performance & Power

Running Power (W): The running power is the amount of continuous power that a generator can provide. It’s vital to ensure that your devices don’t require more power than what is available. Both the Honda EU70is (5500 W) and Yamaha EF6300iSE (6300 W) can comfortably supply heavy-duty appliances like water heaters or welders which typically need around 3000 W – 4000 W.

Starting Power (W): Both generators are also similar when it comes to starting power — the initial surge of energy required to start some devices, specifically those with motors. The Honda peaks at 7000 W while the Yamaha maxes out slightly lower at 6600 W.

Engine type: The Honda uses a 390cc overhead valve (OHV) engine while the Yamaha EF6300iSE has a slightly smaller one at 357 cc. OHV engines tend to have better fuel efficiency and lifespan besides providing improved power output.

Rated Output (kVA): Both products show no significant difference here, rating at 5.5 kVA. This means they’re both capable of providing sufficient current for equipment that pulls larger loads.

Inverter: Both these models have inverter technology; great news if you need to charge sensitive electronics as it ensures cleaner power output compared to a conventional generator.

Fuel & Run Time

Fuel Type: Both models use petrol, providing convenience and easy fuel access.

Fuel Tank Capacity: The Honda EU70is bests its rival here with a capacity of 19.2 litres against the Yamaha’s 17 litres. This could mean slightly fewer stops to the petrol station if you choose the Honda over the Yamaha.

Run Time: The Honda excels again at this aspect, offering up to 18 hours of run time at quarter load compared to Yamaha’s 12.6 hours making Honda an excellent choice for extended usage.

Physical Specs

Dry Weight: Adding to its heft is the weight: the Honda weighs in at 118 kg while the Yamaha is lighter by nearly 30 kg at 91 kg, which could make a difference when moving them around.

Size: Honda’s bigger engine and fuel tank make for a larger generator (848 x 700 x 721 cm) than the more compact Yamaha EF6300iSE (78.0 x 61.6 x 69.2 cm).

Wheels: Thankfully, both generators come with wheels which will assist in moving these hefty pieces of equipment.

Outlets & Parallel Use

AC Outlets: Both these generators feature three AC outlets each, enabling simultaneous power for multiple devices.

DC Outlets: Neither of the models has DC outlets as per the information provided.

Parallel Use: Only Yamaha EF6300iSE doesn’t have parallel capabilities mentioned, an essential option if you plan on doubling your power output in future.

Features & Usability

Features like starting system, fuel gauge, oil alert and others all enhance efficiency, user-friendliness and safety.

Both generators offer an electric starter system which many find easier to use compared to recoil starters. Fuel gauge and oil alert systems are present on both units as well; these help in monitoring fuel levels and preventing engine damage due to low oil.

The Yamaha EF6300iSE comes with a brushless alternator which can reduce maintenance while improving efficiency.

Noise Level

The noise levels of these generators differ significantly. The Yamaha EF6300iSE operates at an impressive 58 dBA (akin to regular conversation level), significantly quieter than the Honda EU70is, which registers at a much louder 90 dBA (close to blender noise).

Conclusion

Between the feature-packed Honda EU70is and the user-friendly Yamaha EF6300iSE, your choice should depend on your specific needs. If power output, longer run-time and larger fuel capacity are more critical, the Honda could be the best fit for you. If you prefer lower noise levels, lighter weight and compact design, then the Yamaha EF6300iSE might be your best option.
