KICKER's KPw2 takes the best features of its predecessor and adds convenient volume and track forward/back rubber membrane buttons; and charging capability to a portable speaker that sounds awesome, rain or shine. The cylindrical KPw2 speaker – about the size of a water bottle – fits anywhere (purses, backpacks, water bottle caddies, etc.), with up to 10 hours of output from a single charge. It's the perfect companion for anybody who wants to enjoy their favorite music, wherever and whenever!
