Ion makes a battery-powered box called the "Block Rocker" which is really
a small battery-powered keyboard amplifier. This appears to be selling
for about $180 new. It is loud enough for even large rooms and the usual
outside demo venue, and has an iPod jack (plus RCA inputs).
I noticed that many of the musicians at Pennsic were using a
battery-powered keyboard amplifier from Roland which was suitable even for
the Pennsic performance tent (medium size venue in a tent with no
reflective walls). I don't know anything about model or price, but it
can't be cheap (nothing from Roland is really cheap).
On the other end - I now own an Alesis Sumo 300 keyboard amp. It has a
four-channel mixer, mic inputs, line level inputs, minimal EQ facilities,
and a 300 watt power amp driving a 15" bass driver and horn HF driver. It
has wheels and a handle and is not very heavy, but is definitely not
battery powered. It can be slaved with another Sumo as a stereo PA
system. The Alesis Sumo 300 is no longer made, but can be found used for
$150-$200.
I have fond memories of a demo 30 years ago where we used a pair of 15"
coaxial monitors driven by a Marantz 1060 power amplifier and cassette
tape player. The rock band nearby came over and asked us to turn down our
system....
