[Elecraft] [K2] KBT2 Battery charger/power supply recommendation?

It may be more than you are looking for as you will not need the current it
is capable of supplying, but it's the SEC1223 from Samlex.  23A capability,
as quiet as a mouse rf wise, you will never hear a fan come on and it is
small and extremely well made.  A quick tweak of one preset inside will give
you 14.2 volts which is just about right.  Perfectly safely and without
stressing anything.  I use it to run my K2 and external KPA100. They are
less than 100 ukp over here so should be cheap as anything on your side!
