I'm planning on starting a little side business endevour shortly and I need a generator. I will be running a vacuum cleaner, possibly a compressor, and eventually I will be using it for a travel trailer. Any recommendations? What should I look for and avoid when buying? I may buy a used one to save some money. Thanks
Honda EU2000i. Hands down. Expensive, but oh, so quiet. 2000 watts max, if you need less power, EU1000i at 1KW and $200 or so dollars cheaper. There is also a 3kw model, but now they're getting heavy. (The 2kw weighs about 50 lbs). Only drawback to them is the idiot designed oil fill opening. Buy a funnel and a lenght of tubing!
Rated Watts Out: 5,550
Max Watts Out: 8,550
Horsepower: 10
Type of Engine: Briggs & Stratton OHV
Number of Outlets: 4-120 Volt Household & 1-120/240, 30Apm Locking Outlet
Fuel Tank Size: 5 gallon
Half Load Run Time: 12 hours
That little Honda's a nice unit alright, Yamaha makes one too, but they won't run much of a motor load. A medium shop vac or (not and) a very small air compressure is max.
Figure out the largest load you need to power, then get a generator that is 20% larger in continuose (not peak) capacity.
Always look for the continuose power rating, not peak or surge.
How hard do you expect to use this power, and where?

I put a 1/2" drill motor and an angle grinder on the Honda, and started both at once - Generator hardly burped. Again, they come in 1, 2, and 3KW. As to the
3-400 dollar generators at the home depot/lowes, it all depends on if you can stand the noise. While shopping for the Honda, I ran across a Briggs& Stratton with the same style & specs. for $499, on sale at 449. Too good to be true? Yep. B&S didn't publish one important spec - dB rating. I emailed the seller, who replied that B&S wouldn't furnish a spec, but it was around 75 dB. The Honda is 57-59 light to full load. Normal conversation level is about 58. While 75 doesn't sound like a big increase, remember that for every 3dB increase, the apparent loudness doubles! A 15 dB increase will sound 5X louder!
Anyway, if the sound level is not an issue, go for the cheaper one. But the loud ones seem to get louder the longer you listen to them. Again, MHO.
I have one of the briggs 5.5KW generators and you are correct, it is LOUD. My soultion was to adapt an el-cheapo tractor muffler to it. Sure it adds about ten pounds or so with the custom bracketry, and makes it a little bit bigger but is is Oh so quiet now. Makes the little 1KW Honda seem noisy. BTW: mine doesnt get moved much, so it was no biggy to add the weight and size. Cost about $30 total to add muffler and do fab work.
You need to make sure you know what your power requirements are before you buy your generator. A vacuum can easily pull 12 amps and even a small air compressor can pull 20 amps on startup. A 3500 watt generator isn't going to power that kind of load.

20 amps for compressor (startup), +12 amps vac. = 32 amps total. 32 X 110 = 3520 watts. Obviously you wouldn't start them both at the same time, so why would'nt a 3500 watt work? Did I miss something? I have a Lincoln rated at 7.5 kw that I've hit with a 30% overload, and the engine grunts for a second, and just chuggs on.
It depends on what type of plugs are on the generator. A 3500 watt generator might only have 1 or 2 110v 15 amp plugs, but if it has a single 110v 30 amp plug it should work.
(edited because I just checked out a Honda EG3500 and it does have a 125v 30amp plug)
GotLift should still figure out how much power he needs. I was just throwing out examples with a 12 amp vacuum and 20amp compressor.

The least I will be running is a regular house vacuum cleaner, the most I will be running is a travel trailer. What do you recommend? Is a 5500W generator enough?

2 kw should handle the vac by itself. On the travel trailer, depends on what you are running in it. 2kw probably won't run the Air cond. if equipped, more like 4. Will run a microwave, or charge batteries & run lights, both together. Get the wattage of everything you wish to run, add together the wattages of everthing that will run at the same time, and compare to the biggest item's wattage. Take the larger of the two, add from 20 to 50%, depending on what you feel comfortable with, thats the size you need. Oh yeah, you might want to guesstimate what you could want to run in the future so you don't have to "upgrade" to a bigger one later. Just remember tho, the higher the wattage, the heavier/bigger/bulkier the genset. Another advantage of the Honda/Yamaha gensets - the 2Kw Honda is only in the low 50# range, fueled & oiled.
Weight is a consideration since I will be lugging it around and taking out of my truck by hand at the job site. It has to be under 500lbs. (JOKE). I could probably sling around 150lbs if I needed to.
I have a wife, so if I use it to run a travel trailer I would expect to run the A/C, microwave, TV, DVD player, possibly a satelite, and a hair dryer all at once.
I use mine on a 30ft travel trailer, and if the AC is on and a few other accesories and I turn the microwave on it will trip the circuit breaker. In order to use the micro, I have to turn off the AC. I have a 5.5KW gen.
