These generators are ridiculously quiet. The secret, as I understand it, is that they are low-volt 12v DC generators that take advantage of the new, very efficient inverter technology to produce the needed 120v AC. There are two sizes to choose from in the EU series (Honda’s quietest and most efficient): 1,000 or 3,000 watts. Both have the ability to be hooked up to another generator to double the rating. The 1,000-watt model weighs less than 30 lbs., fits in a trunk, and can power a few appliances. On the other hand, I have used the 140-lb., 3,000-watt generator to power a camp of twenty people in the desert, including a full sound system, for ten days round the clock, and it hardly was breathing hard at all. With an optional cord you can use the 12v DC current directly to charge batteries. These generators also automatically shut off if they get low on oil. They have electric start with pull-start backup. Best of all they completely decimate the track record for efficiency of most gas gennys. Instead of the usual one gallon per hour they can operate for between seven and twenty-four hours (depending on load) on a single 3.5-gallon tank. In short, they take all the usual horrors and worries out of using generators.
