I'm planning to take the KX2 on a long trip, and it occurred to me that
it might be useful to be able to charge my phone from its battery. I
just took apart a cheap automobile charger and wired a socket to its
input. It works down to about 8 V. You could build your own, but at $3
it's hard to beat. If weight weren't an issue, you could just make an
adapter from the battery plug to a cigarette lighter socket.
If you really want to build your own, look at the data sheet for the
MC34063A.
