It worked good for us. While at the campsite we had it plugged in. Then we unplugged it and took it on the golf cart rides and to the pool. It went hours without being plugged in and we had no problem.
Their "5 hour battery" will depend I'm sure on how you are using it. The more volume and bass you use the more battery power it uses.
Super low volume probably gets you 5 hours, rocking out probably gets you an hour or two.
