Choosing the right large portable generator can be a challenge. You need one that can power your home during blackouts, run multiple tools on your job site, or support your food truck – all without being too loud or breaking the bank.

Today, we’ll compare two popular models: Cromtech Outback 4.5kW and DeWalt DXIG3600E inverters. Whether it’s power output, fuel efficiency, noise level or additional features you’re concerned with, this comparison should help you make an informed decision.

Performance & Power

Running Power (W):
The Cromtech Outback 4.5kW runs at 3700 watts, while the DeWalt DXIG3600E is slightly less powerful with 3200 watts. This difference could translate to running a more powerful tool or appliance with the Cromtech model.

Starting Power (W):
The Cromtech Outback kicks off with 4500 watts against the DeWalt’s initial 3600 watts. This might appear trivial until one wants to start large appliances like a water heater which needs a significant amount of startup power.

Engine type:
While both generators use petrol engines, the Cromtech Outback sports a larger size at 212 cc compared to DeWalt’s 121 cc engine that comes with an OHV design known for better performance and durability.

Both models are equipped with inverter technology to deliver cleaner power suitable for sensitive electronics such as laptops.

Fuel & Run Time

Fuel Type:
Both models run on petrol.

Fuel Tank Capacity:
The DeWalt model takes the prize here with a larger tank capacity of 9 litres against the Cromtech’s 7 litres implying fewer refills for the DeWalt.

Run Time:
The Cromtech Outback 4.5kW offers a variable run time ranging from 4 to 12 hours depending on the load, while the DeWalt DXIG3600E offers a set run time of 8 hours.

Physical Specs

Dry Weight:
The Cromtech weights less at 37.7kg, nearly 6kg lighter than the DeWalt DXIG3600E at 43kg so it might be easier to move around even though the size difference between them is marginal.

Only the DeWalt DXIG3600E model comes with wheels attached making it more convenient in terms of movement and transport.

Outlets & Parallel Use

AC Outlets:
Both generators are equipped with two AC outlets which are handy for powering up several devices simultaneously.

DC Outlets:
Extra features such as a USB port and greater amperage (from a DC outlet) are located on this Cromtech model whereas the DeWalt model has dual USB ports.

Features & Usability

Differences are noticed in starter systems where Cromtech offers a trio of remote, electric and recoil options but DeWalt opts for both electric start and recoil method only.
While both models feature oil alerts as standard, only the Cromtech generator includes additional items upon purchase – an extra spark plug and dust cover.

Noise Level

Noise Level:
At full load, the Cromtech model’s noise level ranges from 55-60 dBA (roughly the volume of conversational speech), whereas the DeWalt stands slightly louder at 63 dBA similar to a noisy restaurant’s chatter.
