What the raw specs tell you
These are calculations from the listed specifications, not additional manufacturer ratings.
Weight per kVA
30.5 kg of listed weight per rated kVA. This represents one of the heavier designs per unit of rated output in this dataset.
Engine power / rated output
1.35 kW of listed engine power per kVA of nominal generator output. This is a simple specification ratio, not an electrical efficiency rating.
Listed production span
15 years based on the supplied 1996-2010 range — a very long listed production run.

Honda EX 4000 S FAQ
These answers change with the model’s actual figures and its position within the Honda dataset.
Is the Honda EX 4000 S a high-output generator?
Its 4 kVA nominal output lands around the middle of the Honda dataset (49th percentile). The comparison-group median is 4.15 kVA, so this is broadly a mid-range Honda output figure.
Is the Honda EX 4000 S easy to move?
No — not in the casual carry-around sense. At 269 lb (122 kg), its listed weight is high enough that mechanical help, wheels or multiple people would normally be more realistic than lifting it. Within this Honda dataset it sits at the 97th percentile for weight.
Does the Honda EX 4000 S have a good power-to-weight ratio?
It works out to about 30.5 kg per rated kVA. Compared with the other Honda models that have both figures available, that represents a relatively heavy package for each unit of rated output. This is only a weight/output comparison, not a fuel-efficiency or electrical-efficiency measurement.
Does the Honda EX 4000 S have electric start?
Yes. The supplied equipment data lists an electric starter, which makes routine starting more convenient than a recoil-only setup.
Is the Honda EX 4000 S a quiet or silenced generator?
The supplied equipment data marks the model as silenced. That suggests noise-reduction treatment is part of the configuration, but no dB rating is provided here, so the specs do not support a precise loudness claim.
Does the Honda EX 4000 S have low-oil protection?
Yes. Automatic oil-deficiency shutdown is listed, adding protection against continued operation when oil level is too low.
How does the Honda EX 4000 S engine size relate to its generator output?
The listed engine power is 5.4 kW against 4 kVA nominal generator output, a simple ratio of about 1.35 kW of engine power per rated kVA. That ratio is useful for comparing specification layouts, but kW of engine power and kVA of electrical output are different quantities and should not be treated as a direct efficiency calculation.
