Large portable generators are useful for high-power needs such as home backup during power outages, running multiple tools on construction sites, operating food trucks or coffee vans, or supporting outdoor events or industrial machinery. Choosing the right generator can be challenging due to size, noise level, and budget considerations. This article will compare the ‘Cromtech TG7000iE’, a powerful and quiet option with Bluetooth start and up to 17 hours run time, and the ‘Yamaha EF6300iSE’, reputed as the most powerful and user-friendly model with an optional remote start.

Performance & Power

Running Power (W): The Cromtech TG7000iE offers a continuous power supply of 6000 watts, while the Yamaha EF6300iSE provides slightly more at 6300 watts. When using a water heater (3000 W) or a welder (4000 W), both generators could handle either one at a time, but if you need to power both simultaneously, the Yamaha might be your best bet due to its higher running power.

Starting Power (W): With a peak of 7000 watts, Cromtech has enough burst power for starting high-demand appliances. The Yamaha maxes out at 6600 watts which is also considerable but slightly less than Cromtech’s offering.

Engine type: The Cromtech generator utilizes an LC190FD-2 model whereas the Yamaha features a robust 357cc OHV (Overhead Valve) engine designed for improved fuel efficiency and longevity.

Rated Output (kVA): The rated output of Yamaha is specified at 5.5 kVA indicating that it can handle equipment that pulls more current. Unfortunately, this information isn’t available for the Cromtech model.

Inverter: Both generators come equipped with inverter technology, ensuring they can generate clean power — a feature essential for safely running sensitive electronics like laptops. Inverter generators are usually more fuel-efficient and quieter than standard models.

Fuel & Run Time

Fuel Type: Both generators run on petrol.

Fuel Tank Capacity: The Cromtech model sports a larger tank capacity at 25 litres compared to Yamaha’s 17 litres. This could mean less frequent refuelling with the Cromtech if you’re using the generator for extended periods.

Run Time: The Cromtech TG7000iE can run up to 17 hours at 1/4 load, which is longer than Yamaha EF6300iSE’s 12.6 hours. If you need a generator that requires less frequent refuelling, the Cromtech model may be a better choice.

Physical Specs

Dry Weight: Weighing in at 130 kg, the Cromtech TG7000iE could be harder to move compared to the much lighter Yamaha EF6300iSE at 91 kg.

Size: Measuring 95cm x 76cm x 77cm, the Cromtech model occupies more space than the slightly smaller Yamaha (78.0cm x 61.6cm x 69.2cm).

Wheels: Fortunately, both models include wheels, making it easier to manoeuvre these heavy machines as needed.

Outlets & Parallel Use

AC Outlets: Whether you are powering lightings or appliances, reliable AC outlets are vital. The Cromtech generator comes with three AC outlets (2 x 15 AMP and a stronger outlet at 32 AMP), while Yamaha has only three regular outlets.

DC Outlets: Only the Cromtech has DC output—coming with USB(5V – 2.1 AMP) which could be handy for charging devices like phones and laptop batteries.

Parallel Use: While Yamaha doesn’t support parallel use, it’s not clear if Cromtech has this feature.

Features & Usability

Features: Both models come equipped with an electric starter system, more effortless than traditional recoil methods. Additionally, both have oil alerts for engine protection. The Cromtech model even allows fuel gauging via a mobile app, and its outlets are weatherproof. However, only Yamaha has a brushless alternator for improved efficiency and reduced maintenance.

Noise Level

The noise level of Cromtech is between 70-90 dBA, rather loud and akin to an operating blender. In contrast, the Yamaha EF6300iSE operates at a much quieter 58 dBA, similar to the ambient noise of a busy office or restaurant.
