I'm looking at electrical chain saws, a Poulan and a Husqvarna.

Brand Poulan Husqvarna
Item Number 118147 328965
Bar Length (Inches) 16.0 14.0
Amps (Amps) 13.5 13.5 Horsepower (HP)
3.5 9.7

They are both 13.5 Amp saws, but the Husqvarna gets almost three times the
horsepower of the Poulan. How is this possible?

Also, the Poulan costs about $75, the Husqvarna about $270.

I think it's in the step-down gearing.

13.5 hp? Nah, and i don't believe the 3.5 and 9.7 either. not on a
13.5 amp motor. Maybe .97 and 1.35... that would be more realistic.

i know what you're saying though. Yes the gearing might make a
difference, and I would think that the Husky would have a slower chain
RPM.

But also one reason they rate a higher hp is the shorter bar. The
Husky would be a better saw, but IMO, not a $200.00 better saw.

Manufacturers of electric tools play a lot of games with horsepower.
It's really very simple however.

watts = volts x amps = 120 x 15 = 1800 watts from a typical 15 amp
circuit

1000 watts = 1 kw = 1.34 horsepower at perfect (100%) efficiency.

Therefore the absolute maximum horsepower you can get on a 15 amp
circuit is 1.8 x 1.34 = 2.41

In reality you'd be lucky to get 2 hp at normal efficiencies.

Gearing has nothing to do with it, hp stays the same, RPM and torque
change.

What's more interesting is that they are made by the same company -
Electrolux.

It's all about the label.

Thanks. Thought there must be something fishy going on.

True. instead of torque and hp, I am beginning to like the measurement
of watts, KW,s mega-w's etc.

I think it's a lot more accurate.

some neat things about an electric chainsaw is 1. they're light 2.
great if you just have some yard trimming to do 3. quiet -(well,
sounds like a circular saw but not even that loud.) good for noise
restricted areas, 4. no mix fuel. 5, fuel doesn't go bad in them and
they're easy to start. plug in and pull the trigger. 6 They're cheap.

bad part is unless you get a cordless one, you are only restricted
to the length of your extension cord.

Luckily, my house is about in the middle of a lot 200' long, so a 100' cord
ought to do quite well.
