I noticed that Sam's Club is selling a Coleman "5000 Maxa ER Plus"
generator (10HP Tecumseh engine) for $500. I assume that it's 5000
watts, but I don't have a note of that, and this model does not appear
on their Web site. Does this seem like a good buy? We are looking for
something to keep our refrigerator, freezer, furnace fan and control
circuitry running, as well as provide basic lighting (most of our lights
are compact fluorescent, so the load should be low).
No, I doubt that it's regulated. I wouldn't use it on the computers or
TV/stereo gear: I'd consider a small Honda (with an inverter) for those.

ever-growing pot of cybersoup:
I run my computers and two way radios on the Coleman without any trouble.
There is a 2000 volt/amp UPS between the genset and the computers that smooths
the rough spots out (like when the well pump kicks in)
In actuality, a switching power supply, like in a computer or in many
electronic devices, can take a very wide range of input voltages and
frequencies. So, those items probably will run with no problems. And
as Steve mentioned, a UPS will guarantee continuous power when the
genset hiccups from sudden load changes.

If you plan on puting few hours on it, it may last for many years.
It will probably run all you ask about, but sometimes generators can be hard
on electronics, so be aware!
I have an older Coleman 5000 watt generator. It claims the max output is 6250
watts. 10 HP Briggs engine. I purchased it from Home Depot just before
hurricane Floyd came up the coast around 1999.
At the time I read on the internet that they were cheap machines that quickly
wore out. In real life I run it monthly for 15 - 20 minutes to make sure all is
working and perform annual maintenance including mobil 1 synthetic oil change.
It averages 2 to 3 real uses per year running 4 to 6 hours per event. I have
had no problems with this unit. It does what I ask it to. It runs the well
pump, some lighting, the computers, tv, radio, freezer, fridge, and oil furnace
but NOT all at once. If you run the heat you don't run the well pump, etc. Load
balancing is the key.
The one significant issue is the noise is creates. It is not quiet even with an
extra optional "quiet" muffler. I put it behind a shed out in the backyard as
far away from the house as possible. Otherwise the drone gets to you over the
Decide if it is worth twice to three times the money for a quieter unit but if
all you want to do is keep the food cold, the house warm, be able to flush the
toilet once and awhile and stay in contact with the world the Coleman will
probably do the job. If I had power problems on a more regular basis I would
consider a better unit.
This from personal experience: They have an oil sensor. If the oil runs low,
the machine won't run.
This from my father's experience: If it won't start, don't let the neighbor
spray ether in the spark plug hole. It will sieze the piston, and then throw
a piston rod.
I agree, they are quite noisy. Better than nothing. Chain it to something,
folks like generators and might steal them.
A good idea is to run the generator an hour or so in the morning, plug in
only the fridge for an hour. Then an hour, and plug in the freezer.
Refrigeration equipment has a high startup current. Try them on the
generator while you still have power.
From memory, a galon of gasoline provides about 2000 watts of power for one
