Portable generators are handy tools. They can help keep the lights on during power outages. They can also run multiple tools in construction sites or even sustain a food truck’s needs. But choosing a suitable one may not always be easy, considering factors like size, noise, and of course, budget.
This article will compare two popular models: the Cromtech Outback 4.5kW and the Adventure Kings 3500iO based on their performance, specifications, features, and more. The goal is to help you decide which model fits your needs best.
Performance & Power
Running Power (W): Cromtech Outback has a running power of 3700 watts, while Adventure Kings provides 3000 watts. Less power means you won’t be able to run as many appliances at the same time. For example, with the Cromtech model, you could run more extensive appliances like large freezers or washing machines.
Starting Power (W): Cromtech Outback peaks at 4500 watts compared to Adventure Kings’ 3300 watts. Higher starting power means you can run several devices that have high startup energy needs simultaneously.
Engine type: Both models operate using a similar engine type – an OHV kind with the Cromtech model offering a slightly bigger engine at 212 cc compared to Adventure Kings’ 208 cc.
Rated Output (kVA): For the rated output, only the Adventure Kings stated its kVA at three – it will comfortably allow equipment that pulls slightly higher current to run.
Inverter: Both models come with inverter technology ensuring they provide cleaner power vital for sensitive electronics.
Fuel & Run Time
Fuel Type: Both models use petrol as their primary fuel source.
Fuel Tank Capacity: The Adventure Kings holds more fuel with a 12-litre tank compared to the Cromtech’s 7 litres. This means less frequent refills, although it also may make it a bit heavier.
Run Time: Cromtech Outback runs anywhere from 4 to 12 hours depending on load, while Adventure Kings boasts a 5.5-hour runtime at full load. Longer run time means lower maintenance and less worrying about refilling, especially during extended outages.
Dry Weight: At 37.7 kilograms, the Cromtech model is slightly heavier than the Adventure Kings model, which weighs in at 30.5 kilograms.
Size: The Cromtech Outback measures at 58 x 45.3 x 48.1 cm, while the Adventure Kings comes in slightly smaller at 50 x 48 x 50 cm. Size might be important if storage is an issue.
Wheels: Only the Adventure Kings specifies that it does not come with wheels, meaning transporting it could be slightly more of a challenge.
Outlets & Parallel Use
AC Outlets: Both models feature two AC outlets to plug appliances or tools anytime.
DC Outlets: Only the Cromtech Outback specified that it comes with USB and DC12V-8A outlets great for smaller devices like phones or laptops.
Parallel Use: Parallel use was only specified for the Adventure Kings product where it’s stated as not allowing parallel use.
Features & Usability
Features: Some key user-friendly features of both models vary greatly. For example:
Cromtech’s model offers a remote-starting system amongst electric and recoil options, whereas Adventure Kings only offers a recoil starter system.
The Cromtech device features a digital display indicator providing real-time information while the Adventure Kings uses an overload indicator light.
Additionally, Cromtech has an oil alert feature for added engine protection.
The Cromtech model includes a spark plug and dust cover in its accessories.
Noise Level: The noise generated by the Cromtech Outback ranges from 55 to 60 dBA, which is similar to a conversation or the humming of a refrigerator. In contrast, the Adventure Kings produces between 66 to 74 dBA, making it comparable to city traffic or a vacuum cleaner.
