Short answer: the Teufel Rockster Air for battery, the JBL Partybox 300 for sound. The Rockster Air runs an exceptional 58 hours, has a user-replaceable battery and reaches 112dB, but its midrange is peaky, it is not very natural and it distorts above half volume. The 300 has 2x 6.5-inch woofers, an 18-hour battery and hard punchy bass, but it is hard to carry and its bass extension is only as good as a Partybox 100.
Buy the JBL Partybox 300 if you want a party speaker. Buy the Teufel Rockster Air if you want a battery-powered PA speaker instead.
