Choosing a large portable generator can be difficult. Whether your needs are for home backup during power outages, running multiple tools on a construction site, operating food trucks or coffee vans, or powering outdoor events or industrial machinery, finding the right generator is key.

Today, we’re comparing two models – the Hyundai HY3200SEi and Adventure Kings 3500iO – based on their power and performance, fuel efficiency, physical specs and outlet capacity to help readers decide which model is best suited to their needs.

Performance & Power

Running Power (W): At 3200W, Hyundai HY3200SEi beats the Adventure Kings 3500iO which runs at 3000W. This means that for continuous power use, like running heating systems or industrial vacuum cleaners both generators are suitable.

Starting Power (W): Both generators are comparable in terms of start-up power. Adventure Kings 3500iO has a slight edge with its maximum start-up power of 3300W compared to Hyundai’s 3200W. However, this slight advantage is unlikely to make a significant difference in practical use.

Engine type: Both generators run on similar engines: Hyundai uses a slightly larger engine at 210 cc OHV while Adventure Kings uses a 208 cc, 4-stroke OHV engine. The OHV design improves fuel efficiency and lifecycle spanning.

Rated Output (kVA): The rated output displays how much apparent power a generator can produce. The Hyundai HY3200SEi quite visibly outruns the Adventure Kings at a rated output of 4kVA as opposed to the latter’s 3kVA rating.

Inverter: Both the Hyundai HY3200SEi and Adventure Kings 3500iO are equipped with inverter technology, which gives cleaner and quieter power output, ideal when you’re powering sensitive electronics.

Fuel & Run Time

Fuel Type: Both Hyundai HY3200SEi and Adventure Kings 3500iO run solely on petrol which fuels their OHV engines.

Fuel Tank Capacity: The fuel tank capacity of Adventure Kings 3500iO stands at 12 Litres versus the Hyundai’s 7.8 liters. This difference means that with the Adventure Kings generator, refuelling will be needed less frequently than the Hyundai.

Run Time: While the Hyundai operates for 6 hours at 50 % load, Adventure Kings runs for a less time of 5.5 hours at full load. This means that Hyundai generator is more likely to last longer without needing to be refueled.

Physical Specs

Dry Weight: The Hyundai HY3200SEi weighs in at 35 kg whereas the Adventure Kings 3500iO is a little bit lighter at only 30.5 kg. These small differences may make the Adventure Kings slightly easier to handle and transport.

Size: In terms of dimensions, the Hyundai HY3200SEi measures 40 x 40 x 56 cm while the Adventure Kings 3500iO is a bit bulkier at 50 x 48 x 50 cm. This implies that although heavier, the Hyundai will occupy lesser space, making it a better fit in limited spaces.

Wheels: Unfortunately, there isn’t any information about wheel facilities for these two generators.

Outlets & Parallel Use

AC Outlets: Both generators equate with two AC outlets each, providing ample power options for multiple appliances simultaneously.

Neither of the two generators feature DC outlets nor parallel functionality.

Features & Usability

Compared to the recoil start system on the Adventure Kings model, Hyundai features an electric/remote starter system making it more user-friendly. For performance monitoring, Hyundai includes a digital display while Adventure Kings only provides an overload indicator light. Both models include safety features for smooth operation, with overload protection as standard and low oil shutdown for the Hyundai generator.

Noise Level

As expected, a noise difference is evident. The Hyundai HY3200SEi operates at a significantly quieter 54-59 dBA, pitched at normal conversation levels, while the Adventure Kings 3500iO hits a higher decibel range of 66 (at idle) to 74 (2KW load), which is closer to the vacuum cleaner sound level.

In conclusion, the Hyundai HY3200SEi may be more suited for users seeking lower noise levels and longer run time despite having a smaller fuel capacity and being heftier. Conversely, the Adventure Kings 3500iO could appeal to those desiring more powerful continuous operations in a lighter package. It’s important to bear in mind that the best choice will depend largely on prioritised features and specific power demands.
