On my road trips, I typically take my Flip 3 and my friend gets his Charge. And they both make for a good time. Decent sound and long enough battery life. Since I typically don't use anything at max volume, I couldn't see much of a difference between these two apart from the higher battery life of the Charge. But then the usecase has been not too loud music on the calm areas like beaches or mountains rather than loud house parties so take that with a pinch of salt.
