Generators can be a lifesaver during power outages, offering a reliable backup for your home. They also bring power to remote sites for construction tools, fuel food trucks, and acquire electricity for outdoor events or heavy machinery. But, finding the right generator involves finding the right size, managing sound levels, and working within your budget.

Today’s comparison places Cromtech Outback 4.5kW against Hyundai HY4000SEi. Both models are marketed for their noteworthy features: Cromtech touts pure sine wave technology and quiet operation while Hyundai highlights its performance and compact design.

To help you decide between these two models, we’ll evaluate them on power performance, fuel use and runtime, physical specs, outlets, usability features, noise level, and utility.

Performance & Power

Running Power (W): The Cromtech offers 3700W and the Hyundai delivers a slightly higher 4000W. The running power is the continuous power a generator can deliver; it’s important that your device requirements don’t exceed this number. For instance, using the Hyundai model could power a water heater (3000W) or even a welder (4000 W). Having higher running watts generally means being able to power more things at once.

Starting Power (W): Starting power is the burst of energy needed to start devices with motors. The Cromtech generator has a starting power of 4500W compared to Hyundai’s 4000W. This might not matter unless you’re using appliances that need an initial burst of high energy to start up.

Engine type: Both generators are equipped with engines around the same capacity (Cromtech – 212 cc; Hyundai – 223 cc) and run on petrol. The Hyundai engine also has an Overhead Valve (OHV) design which is known for better fuel efficiency, engine life, and power output. A feature the Cromtech model doesn’t specify.

Rated Output (kVA): Not specified in Cromtech; Hyundai – 5 kVA. The rated output measures the generator’s apparent power that combines real and reactive power. Real power does useful work while reactive power is needed for some equipment to operate. Having a higher kVA rating like that of Hyundai might be beneficial if your appliances pull more current.

Inverter: Both Cromtech and Hyundai generators have an inverter. Inverters produce clean power, safe for sensitive electronics like laptops. They also tend to run quieter and use less fuel.

Fuel & Run Time

Fuel Type: Both models run on petrol.

Fuel Tank Capacity: Cromtech has a 7L tank while Hyundai has a larger 9L tank. A bigger tank means you could go longer without refilling but the unit will be heavier.

Run Time: Hyundai’s runtime isn’t specified. As for Cromtech, it varies from four to 12 hours, depending on the load size. Depending on your needs, this would either allow you to work continuously through the day or need frequent refills.

Physical Specs

Dry Weight: Hyundai weighs more (55kg) than Cromtech (37.7kg). A lighter model like Cromtech would be easier to transport but could compromise on other features like fuel tank size or power output.

Size: The difference in size between these two generators is marginal with the Hyundai being only slightly larger than Cromtech’s 58cm x 45.3cm x 48.1cm. This shouldn’t impact storage nor transport too much.

Wheels: Neither product specifies whether they have wheels which could affect their portability particularly if you plan on moving them frequently.

Outlets & Parallel Use

AC Outlets: Both Cromtech and Hyundai generators are equipped with two AC outlets, allowing you to power more devices simultaneously.

DC Outlets: Cromtech comes with a USB (5V-2A) and DC outlet (12V-8A) while Hyundai does not specify its DC outlet features. These can be used to charge smaller appliances and batteries providing additional convenience.

Parallel Use: Neither product mentions the option for parallel use which would’ve doubled the power output by linking two of the same generators together.

Features & Usability

Cromtech stands out with its remote, electric and recoil starter system, offering versatility compared to Hyundai’s lack of specifics. An added bonus is Cromtech’s oil alert feature – an essential safety measure that notifies you when oil levels are low, preventing damage to the engine.

Noise Level

In terms of noise generation, both models are quite similar. Cromtech operates at 55-60 decibels (dBA), much like a normal conversation or a household refrigerator. Hyundai runs slightly louder at 59 dBA but it’s still about as loud as a conversation.
