Short answer: the Teufel Rockster Air if battery life is what matters most. Its claimed 58 hours, or 31 at full volume in ECO mode, and its user-replaceable cell are unmatched here, and it plays to 112dB, but the midrange is peaky and it distorts above half volume. The Ultimate Ears Hyperboom is the better-behaved of the two for sound, at the cost of output and that battery advantage.
Buy the Teufel Rockster Air if you want a battery-powered PA speaker. Buy the Ultimate Ears Hyperboom if you want a party speaker instead.
