A portable generator can be beneficial for various reasons – from powering camping trips and outdoor events to providing backup power during outages. However, picking the right one can be a challenge. You need to find a generator that’s right in size, isn’t too loud, and is within budget.

In this article, we’ll compare two models: the Cromtech Outback 2.4kW and Engel R2500IS. Both are inverter generators. This means they can produce clean electricity safe for sensitive electronics like laptops and phones. These two models also promise durability and good performance, but they do have differences that might affect your buying decision. We will compare their performance, power, fuel usage, physical specs, additional features, and noise level.

Performance & Power

Running Power (W): The Cromtech Outback offers a running power of 2100W while the Engel R2500IS touts a slightly higher running power of 2500W. This indicates how much continuous power each generator can supply. When using these generators, it’s essential to make sure your devices’ total running watts don’t exceed these numbers. For example, both generators can independently power a large air conditioning unit requiring approximately 2000 W.

Starting Power (W): The Cromtech Outback’s starting power is 2400W while the Engel R2500IS remains at 2500W. Some devices need extra power when they start, and these figures indicate how much each generator can provide for a short period of time.

Engine Type: The Cromtech Outback uses a 79cc OHV engine, while the Engel R2500IS utilizes a larger 122 cc engine type which is more powerful but not stated as being OHV – an engine design that typically yields better fuel efficiency and output.

Inverter: Both the Cromtech Outback and Engel R2500IS incorporate inverter technology, ensuring a clean power supply ideal for sensitive electronic devices.

Fuel & Run Time

Fuel Type: Both the Cromtech Outback 2.4kW and Engel R2500IS use petrol as their fuel source.

Fuel Tank Capacity: The Cromtech holds a little more fuel with a 5.0 L tank versus the Engel’s 4.5L capacity. This may influence how often refuelling is required.

Run Time: The Cromtech provides a long operating time of up to 20 hours at a quarter load, while the Engel is slightly less running for 3 hours at full load.

Physical Specs

Dry Weight: The Cromtech is lighter at 19.8kg, making it easier to transport compared to the Engel model, which weighs in at 23.5kg.

Size: Size-wise, there’s very little difference between the two generators, only marginal differences in dimensions.

Wheels: Unfortunately, neither of these two models come with wheels attached which might make their portability more challenging.

Outlets & Parallel Use

AC Outlets: The Cromtech wins out here with two Single Phase AC outlets allowing for more devices to be powered simultaneously compared to the Engel which only has one 15 amp outlet.

DC Outlets: Here, both generators provide DC Output but differ in their offerings. The Cromtech has two USB outlets and one 12V-8A outlet while the Engel offers USB outlets at different amperages: one at 1A (5V) and another at 2.1A (5V).

Parallel Use: While it’s not specified for the Cromtech, the Engel generator allows parallel use where you can connect another identical model to double its power output. This is especially useful for larger applications that require more power.

Features & Usability

Features: Both generators use a Recoil Start system, and the Cromtech comes with a Low Oil Alarm and Overload Protection. They also both include Outlets. Notably, Engel offers safety features such as Overload Protection and provides a convenient fuel gauge.

Noise Level

Noise Level: If noise level is a concern, the Cromtech operates quieter at 52-64 dBA compared to the Engel’s louder 68 dBA rating.

Choosing the best generator depends on your specific needs and circumstances. The Cromtech Outback might be better if you need to power more devices simultaneously due to having more outlets or prefer lower noise levels. However, if you’re looking for more power overall, then Engel R2500IS may be your better option, particularly for larger tasks requiring longer run hours.
