Q: What is the difference between the Honda EB, EM and EU generators?

by Thomas W Murphy from Wisconsin on June 26, 2014

A: Thanks for your inquiry.

The Honda EU series is considered the "Super Quiet" series and range from 1,000 watts to 7,000 watts. These units are totally enclosed and primarily used for recreational purposes.

The Honda EB series are considered "Industrial" and range from 3,000 watts to 10,000 watts. These units have Full GFCI protected outlets to meet OSHA standards on jobsites.

The Honda EM series are considered the "Deluxe" series and range in 4,000 watts to 6,500 watts. These units have electric start and are primarily used for home backup.

Q: Is there anything I need to know about these generators since they have a longer filler neck?
by Karen from Illinois on March 15, 2011

A: This generator has a longer filler neck and filler cap/dipstick for checking the engine oil.

This generator must not be filled with oil until the oil runs out of the filler neck. This will cause the engine to be overfilled with oil.

You must use the gauge in the oil filler cap/dipstick to verify the correct amount of oil in the engine. The engine is full of oil when the oil is up to the top of the cross-hatched area of the filler cap/dipstick. As always, do not screw in the filler cap/dipstick when checking the oil level.

You can find this information in the Owner's Manual as well.

Quality Generator
Received the EM4000 generator with lift gate delivery. Easy handle and wheel assembly. Wheel kit is stout. Filled with oil and fuel and fired right off. Warmed up before I put a 1500 watt load on. Motor was surging slightly for about 10 minutes. Was slightly concerned but figured it needed to break in. Came back a hour later and it was running smooth. Huge difference in noise decibels from my previous generator, brand doesn't matter. We needed to upgrade to electric start, wife couldn't start... more
Pros: Easy To Use, Quiet, High Quality, Easy To Store
Cons: Expensive

Like The Honda Em4000 Generator
Received my generator as scheduled. There was no shipping damage and the assembly was very easy. The handles fold up to help with storage space, and moving the unit was easy. Gasoline was added and unit fired right up with the electric starter. The manual pull starter worked as promised too. We are very pleased with the quiet operation which was much better than my previous unit.

Waiting For My First Use
Purchased my generator to be ready for this summer, after 5 days with no electricity last year, courtesy of Hurricane Irene. It's all set up and ready to go whenever the power goes out. Nothing but good things to say about PED/EGD. Good website, great service. A shout out to Josh, who was very patient working with me to answer my questions and take my order over the phone.

Honda EM4000SX generator: it's everything I expected. Construction seems solid, easy starting, easy to understand... more
