From backing up your home during a power outage, running multiple tools on construction sites to supporting outdoor events or a coffee van, portable generators serve many purposes. However, choosing the right one that delivers ample power, isn’t too loud and fits your budget can be challenging.

Today, we’re comparing two popular portable generators – the DeWalt DXIG3600E and the Ryobi RPGENINV4K. We’ll examine their varying specifications and features, addressing key points of difference to empower your decision making.

Performance & Power

Running Power (W): DeWalt DXIG3600E offers 3200 watts while Ryobi RPGENINV4K provides slightly less at 3100 watts. Running power refers to the continuous power a generator produces. Both can comfortably support high-drain appliances like water heaters or industrial vacuums that require around 3000 watts.

Starting Power (W): The DeWalt model provides a starting power of 3600 watts, while Ryobi’s generator peaks at an impressive 4000 watts. This high starting power is crucial for devices that need extra power to begin operation.

Engine type: Both generators use Overhead Valve (OHV) engines, renowned for fuel efficiency, improved power output and longer lifespan. The DeWalt model features a 121cc engine while the Ryobi model has a larger 212cc engine size.

Inverter: Both models are equipped with inverter technology, producing cleaner energy suitable for powering sensitive electronics such as laptops with less risk of damage.

Fuel & Run Time

Fuel Type: Both models use petrol fuel types.

Fuel Tank Capacity: The DeWalt has a 9 litre tank capacity which compares to Ryobi’s larger 12 litre tank. Having a larger fuel tank extends the time between refills, but will make the unit heavier.

Run Time: The DeWalt has an 8-hour run time at 1/4 load while the Ryobi outlasts it with a run time of 12 hours at half load. Longer run times indicate fewer refills required and extended uninterrupted power supply.

Physical Specs

Dry Weight: The Dewalt is a tad heavier at 43 kilos, compared to Ryobi’s 35 kilos. A heavier generator might be more tricky to move around.

Size: The Dewalt measures 64 x 39 x 45 cm while the Ryobi is slightly bigger at 58.5 x 38 x 54 cm. A larger generator will occupy more space, so consider where it’s going to be stored or transported.

Wheels: Both generators come with wheels for easy mobilisation.

Outlets & Parallel Use

AC Outlets: The DeWalt provides two AC outlets compared to Ryobi’s three. More outlets mean you can power more devices simultaneously.

DC Outlets: Only the DeWalt model features DC outlets – including two USB ports and a traditional 12-volt outlet. DC outlets are particularly useful for charging smaller appliances like phones or laptops.

Parallel Use: Unfortunately, only the DeWalt model specifies whether it allows for parallel use or not—but doesn’t provide clear information. Allowing for parallel use would mean that you could connect two of the same models together, effectively doubling your power output.

Features & Usability

Features: The DeWalt benefits from features such as an electric key start/recoil, LED indicator for fuel and power, oil alert and low oil auto shut off system which ensures no inadvertent damage is done if oil levels drop too low. While it doesn’t indicate whether a brushless alternator and spark arrestor are present, they’re typically standard on modern generators.

The Ryobi model, on the other hand, champions easy start technology but omits detailed information about additional features.

Noise Level

Noise Level: A lower dBA means quieter operation – and at a 1/4 load, the DeWalt runs at 63 dBA compared to the Ryobi’s louder 67 dBA. For perspective, these levels are lower than heavy city traffic (85 dBA) but likely louder than a normal conversation (60-70 dBA).

Upon comparison, it’s clear that both the DeWalt DXIG3600E and Ryobi RPGENINV4K have their strengths. The DeWalt’s main advantages are in running power and noise level. In contrast, the Ryobi’s larger fuel tank size means longer run times and its greater starting power can make a significant difference when you’re starting up appliances with large motors initially.

Bear in mind these suggestions match certain requirements – you must decide what features top your list of priorities.
