Small inverter for emergencies

I've had several laptops in the last few years, and a 300W inverter is
barely adequate most times to keep it going.

Really ? Have you bought ones with desktop CPUs, powerful graphics
cards and lots of fans ? My reasonably new (~2 years old) laptop draws
just 27W when the battery is full and runs beautifully on my 150W
sinewave inverter. Then again, it is better to use the 12V adapter
accessory than an inverter.

If you can get past the startup surge, most furnace motors are 1/6 to
1/3 horsepower, and consume about 1-1.5 amps, which is a little more
than 120-160 watts.

I was window shopping for inverters the other day. One thing I noticed
was that the peak power rating seemed to be worthless. I quote:
400Watts 800watts peak (for 0.01 seconds).

Shucks Auto supply had a brand PowerXone
Auto Zone had Schumacker
and CarQuest had Vector.

CarQuest had by far the highest prices around.

For sure. But those are a relatively rare, and with $300 Chinese
generators showing up seemingly everywhere, the days of making use of
such old stuff are all but gone. I still have some 50 year old
equipment here, but my last small engine without recoil start was
about 35 years ago. I did have to start one on a friend's cement mixer
a while back. Wrapping shaggy poly rope around the remains of the
long-gone recoil starter's hub. And an old wool sock for an
air-cleaner to boot.

On Ebay there is a guy selling these little 850 watt 2 stroke generators for
$134.99 with free shipping. The feedback on these units seems good. They
have a 6.2 hour run time on 1.2 gallons of fuel.
Our power was out for more than a day and I didn't want to start my 5,000
watt generator, even though it has a full tank of gas. I was about ready to
fire it up to run the well when the power came back on.
We used a small camping propane heater and propane lantern. We got 4.5
hours of heat on one 16 oz propane tank. So we also got light and heat from
the lantern. It was 26 degrees outside during the power outage. Yet we were
nice and warm and had hot food from the small camp stove. A small B&W TV for
entertainment that ran on D batteries.
Yet even though we did fine a small 3,000 watt generator would have been
nice. I have been thinking about one of these inverter generators on Ebay
for about $300.00. He claims a 15 hour run time on 12 liters of fuel. But I
don't know anything about these generators. Are these better than the 3,000
watt units at Shucks auto parts for $329.00?
Also when I replace an alternator it comes with a warning that it's not
for battery charging, but only for maintaining a charge in a battery. So
does this mean that an inverter run from a car is not a good idea?

Just try not to pull too hard on the starter. The little plastic bits in
mine have shattered (probably not intended for use in -20C and lower) and
reconstructing it has proved too much for me.
