bought this speaker from kmart

plugs into the same power supply, as i use with the ozone machine...12volt battery and invertor...today took that into Northbridge to play a few tracks... it has good sound quality, a little heavier in the 40L backpack, also took an ionizer to refresh the air, which plugs into 12volts...then had a nice croissant and coffee, and rode home on my electric bike... Live is good lol
