i think the package said it was 14 oz.
Three weeks later and we still use this quite a bit. Whether its in the shower, sitting outside on the screen porch- this thing has tooken over my big monster bluetooth radio- or just sitting at the kitchen table with it on while im working on a vinyl project. It has really came in handy and very very very portable! This is deff a 5 star for me !
