Short answer: the Wonderboom 4 keeps things small, the Charge 2 keeps your phone charged. The Wonderboom 4 is notable for its small size, but its bass is not as deep as the top-ranked speakers and is a little thuddy. The Charge 2 doubles as a 6000mAh power bank, though its bass compresses at higher volumes.
Buy the Ultimate Ears Wonderboom 4, since the JBL Charge 2 is discontinued and only worth hunting down used.
