Hi Everyone,

I'm looking at picking up a Chicago Electric Generator Model# 97906
from Harbor Freight to run a few things around the hose incase of a
power outage, but I was wondering about the 12V Battery Charging
Socket. Could I run any 12-volt item, specifically a 2m amateur
radio, from this, or is it designed specifically for charging a
battery and nothing else? I've read through the manual online -
http://www.harborfreight.com/manuals/97000-97999/97906.pdf - and it
just mentions using it for a battery ... but it'd be nice to use this
for my radio as well.

Just checking...

Thanks,

Alex

Probably not. Since it's explicitly described as being a battery
charge circuit, it's unlikely that the voltage regulation would be
particulary good, especially when your rig is in receive mode drawing
little current. The amount of noise on the DC would probably be
pretty bad too.

On the other hand, running your rig from a battery which you charge
from the generator (with appropriate filters and charge and voltage
control circuitry) wouldn't be a bad idea.

With the emphasis on emergency preparedness in the past few years,
QST's been full of articles describing how to do this, and ARRL even
has a book, "Emergency Power for Radio Communications", covering the
subject.

I would think that as long as you had a car battery connected, in
addition to your radio, it'd work OK. The battery acts as a BFC,
soaking up transients and boosting sags. If you really want to go
overboard, I'd try an Optima yellow top deep discharge gel battery.

It would be totally 0-14 volts 10 volts average, unless its three phase.
Use a battery in parallel.

What everyone else said. The output from most home generators is
electrically pretty noisy. If I hook my PC up to my generator it runs
fine but when I stick in a UPS in between them (which I always do) I
have to turn off active line monitoring as it is going off almost
continuously.
