[Elecraft] Looking for miniature 14-V power supply for travel

[Phil Hystad]

I bought some nice A123 Li batteries for this kind of thing.  A 3-cell or 4-cell works great and may even last all day and then some with QRP power.  If you had a 100 watt amp, you could run that too!  I bought these from Buddipole and they work great.  Get the little 10s charger too.  Pricey solution but very conveniet.  Batteries are extremely RF quiet.
