[Elecraft] [K3] UPS for K3

[David Cole]

For those that like to build things, see:

http://k2jji.org/files/Power_Gate_Assembly_Instructions_v2.pdf

for instructions on building your very own power gate...

Even has a rudimentary battery charger you can add...  The devices cost
a whopping 3 bucks delivered from eBay.

This item is a compact, relatively low cost, well regarded solution that would be appropriate for use in the scheme Bruce has suggested. A yellow or blue top Optima, or other good AGM battery, along with a PWRgate, wouldn't cost too much more than the UPS being considered, but would be much more useful & versatile.
