Here, we’re looking at two big portable generators – the Cromtech Outback 4.5kW and the Engel R3000IE. You might need such a machine if you require large amounts of power during blackouts, if you run multiple tools on construction sites, or for outdoor events.

The downside is that choosing the right model can be challenging. This comparison will focus on their performance, fuel efficiency, physical specs, outlets, noise levels and more, to help you choose the best one.

Performance & Power

Running Power (W): This describes how much continuous power a generator provides. The Cromtech Outback can supply up to 3700 watts while the Engel can deliver up to 3500 watts. Therefore, the Cromtech offers slightly more power and could run appliances that require higher running power such as a water heater.

Starting Power (W): For devices needing a burst of power at start up, starting power is important. Here again, the Cromtech reigns superior with 4500 watts compared to Engel’s 3500 watts.

Engine type: Both models make use of a robust 212 cc engine but it’s not specified whether they are OHV.

Rated Output (kVA): For Engel, we’ve got a rated output of 3.5 kVA which isn’t specified for the Cromtech model.

Inverter: Both these models feature inverter technology which is good news because this can result in cleaner power essential for electronics and they tend to be quieter and fuel-efficient.

Fuel & Run Time

Fuel Type: Both generators run on petrol.

Fuel Tank Capacity: Relatively, the Engel boasts a larger fuel tank (8.3L) compared to Cromtech’s 7L, meaning potentially longer run times between refills with the Engel.

Run Time: The Cromtech’s run time varies between four to twelve hours whereas the Engel will reliably run for roughly 8.5 hours at half load. Depending on your needs, either could be advantageous.

Physical Specs

Dry Weight: Weight impacts portability, with the lighter model (Cromtech Outback) possibly being easier to handle at 37.7 kgs as opposed to Engel’s heftier 44.5 kgs.

Size: In terms of dimensions, both models are similar with the Cromtech model slightly smaller.

Wheels: The Engel has wheels that make manoeuvring easier although it’s not stated if that goes for the Cromtech model too.

Outlets & Parallel Use

AC Outlets: Both generators come equipped with two AC outlets allowing you to power multiple devices simultaneously.

DC Outlets: Both models offer DC outlets handy for charging batteries or smaller devices. The Cromtech features a USB outlet while the Engel supplies 12V at 8.3A.

Parallel Use: It’s specified that the Engel allows for parallel use and unfortunately it’s not clear if this is also true for the Cromtech.

Features & Usability

Both generators come with handy features like an overload alarm, output indicators, and remote/electric/recoil start system for ease of use. However, additional features and accessories included differ between the two models.

Noise Level

When considering noise levels, the Cromtech Outback (55-60 dBA) runs quieter than Engel R3000IE (67 dBA).
