It is a 2-channel amp, (yes it has an XLR input) with built-in recharageable power source that is supposed to run 10 hours or so.
It is wedge-shaped like a monitor; also can be set up vertically on a stand (yup you could use 2 together with an unpowered board for a ultra-transportable mini-PA), the guy that showed it to me is someone I trust for many years back (I didn't plug in and try it); and there is a larger 30-watt variant for an entirely reasonable $230 Cdn!
If I was in the market, I'm pretty sure I would use this as the benchmark cause it has everything I'd be looking for including price. W-O
