Honda EM5000S Overview
The Honda EM5000S is a 5,000-watt, 120/240 V portable generator with electric start, built for backup power during outages and brownouts. It is part of Honda’s Deluxe Series, which uses a heavy-duty full frame, wide handles, voltage regulation and several front-panel outlets, and it includes CO-Minder carbon monoxide shutdown.
A 389cc iGX390 engine drives it, and iAVR regulation limits voltage swings while permitting 7,000 watts for 10 seconds to start larger loads. The generator can run in 120/240 V mode or in 120 V only, which makes the entire output available through any 120 V outlet within that outlet’s own limit. Honda lists a 3-year limited factory warranty. Honda adds that the EM Series delivers quiet, durable and efficient power. Noise is listed at 66 dB(A) at rated load and 63 dB(A) at 50 percent load. The unit weighs 226.4 lb and measures 41.1 x 27.8 x 28.3 in.
