[Elecraft] Car-Starter battery packs

[Lynn W. Taylor, WB6UUT]

Don't know how much you've looked at these Phil.

Almost without exception, they provide USB "phone" charging and other 
low-current (compared to car-starting) outputs.

They're not optimized for running a rig (or a laptop or a phone) but 
they do have a stack of lithium cells and some protective circuitry for 
a very attractive price.

I agree that I wouldn't use one as a backup power in commercial service, 
but for what I need they seem to work well.

Sometimes perfect is the enemy of good-enough.
