Functions and Features

The Honda EG4000 is packed full of unique functions and features, each one making this portable generator fit for many powering situations. Let’s take an in-depth look at each of these so you can gauge the power of this machine.

DAVR

DAVR, or digital automatic voltage regulation, is an advanced technology that is designed specifically for consistent power and enhancing the performance of the Honda EG4000. This voltage regulation can hold the voltage stability within a +/- 1% range during operation, making for much more consistent power.

CO-MINDER

CO-MINDER is an advanced carbon monoxide detection system. Essentially, this means that CO levels will be constantly monitored since these fumes are dangerous to breathe in. If the CO levels are high enough, the Honda generator will automatically shut down for user safety.

120/ 240V Selector Switch

As I’ve mentioned above, the Honda EG4000 has three means of output. This selector switch allows you to choose between using both the 240 and 120 volts, or 120 volts only. This switch allows for the total output of the generator to be available through any of the 120-volt outlets. This adds more versatility to the generator since the switch enables you to power units that have larger wattage requirements. This also means more usable power.

Honda Oil Alert

The Honda EG4000 is protected by Honda Oil Alert. This protects the generator when low oil levels are detected by shutting off the engine.

Long Run Time

The run time for the EG4000 is an impressive 14.8 hours @ 50% load (6.3 gallons). This keeps your generator running all day long no matter what.

Durable Frame

This portable generator features a one-piece welded frame, designed specifically to help protect the generator. This is especially useful in situations where you are using this generator outside, or during an emergency where things can quickly become chaotic.

Spark Arrestor/Muffler

The EG4000 features a USDA-qualified spark arrestor/muffler.

Fantastic Warranty

Last, but certainly not least, who can forget the 3 years commercial warranty?

With the Honda EG4000, you don’t need to worry about a generator that isn’t safe, dependable, or practical. Each feature of the EG4000 addresses most concerns that you’d have with purchasing a new generator. This Honda generator is truly an asset no matter what you’re using it for.
