Re: [Elecraft] [OT] Jump starter system for K3 portable power?

[Ramon Tristani]

I bought one of these:

http://www.harborfreight.com/5-in-1-portable-power-pack-with-jump-start-62747.html
 


Seems to be more than enough to fill up tires, drive AC power tools and feed 
some 12 volt equipment within its ratings. I don’t know if this is exactly what 
you want or need but for its purpose it has worked just fine for me.

Re: [Elecraft] [OT] Jump starter system for K3 portable power?

[Richard Fjeld]

Rick,
I don't know if you will find something that meets all your 
requirements. Perhaps you will need to modify something that has the 
hardware you want.

In my limited exposure to jump starters, I have found that the data is 
sometimes vague. I have had the same brand be both good, and sorry.  I 
have also found unusual sized gel-cells within. So I want to consider 
battery replacement.

There are 'boat' batteries that are a compromise for both deep cycle and 
starting.  They come with some weight, and charging considerations.

I will be interested in the replies you receive.

Dick, n0ce
