Short answer: the Teufel Rockster Air 2 for off-axis consistency, the JBL Partybox 300 for battery. The Teufel’s single horn-loaded compression driver gives it more consistent off-axis sound than a JBL Partybox 130, though its bass is not as deep as that JBL’s boosted low end, which is boomy, not truly deep. The 300 has an 18-hour battery and hard punchy bass, but it is hard to carry and its bass extension only matches a Partybox 100.
Buy the JBL Partybox 300 ($300) for a party speaker; the Teufel Rockster Air 2 ($599.99) suits a battery-powered PA speaker instead.
There is a real battery-life gap here: the Teufel Rockster Air 2 is rated for 58 hours, the JBL Partybox 300 only 18 hours.

JBL Partybox 300: $300 Discontinued eBay
Newer model: the JBL Partybox 330, ranked higher, rated 4.6/5.
Pros: Exceptional sound quality with crisp, crystal clear highs and midranges, hard punchy bass without muddiness. 2x 6.5” woofers + 3x 2.25” tweeters, bass boost function, 45Hz-20kHz frequency range. 18-hour battery with 10400mAh capacity. Multiple inputs (RCA, USB, 3.5mm aux, mic, guitar). LED light modes (meter/pulse/party). True Wireless Stereo pairing up to 2 units. Measured bass extension of 40Hz (-10dB).
Cons: Hard to carry, too tall, drags on the ground. Max spl and bass extension are only as good as the Partybox 100. No real reason to ever get one, get a Partybox 100 instead. Discontinued.

Teufel Rockster Air 2: $599.99 Amazon eBay
Older model: the Teufel Rockster Air (ranked lower, rated 3.4/5).
Pros: More consistent off-axis sound than the JBL Partybox 130, thanks to its single horn-loaded compression driver. Projects sound more evenly to the sides, unlike the JBL’s narrower front-firing dispersion. Cleaner instrument separation at high volume than the JBL Partybox 130, which turns anemic and loses bass at max volume despite its bass boost.
Cons: Bass isn’t as deep as the JBL Partybox 130’s boosted bass, though the JBL’s is boomy rather than truly deep. Bass and treble aren’t perfectly controlled at maximum volume: can sound hollow or too bright unless turned down from default. Not meaningfully louder than its 3-year-old predecessor, and the reviewer found the overall tuning a bit worse.
