Short answer: the B&O Beolit 20. It ranks #46 of 99 boombox speakers by sound quality (rated 3.4/5) at $749 and is still sold new; the Teufel Boomster NG (2017) ranks #56 (rated 3.2/5) and is discontinued, so it is only an option used. The Teufel Boomster NG (2017)’s replacement, the Teufel Boomster 4, is rated 3.4/5.
The case for the B&O Beolit 20: Wireless phone charging. Watch for: Warm sound. Rolled off treble. Bass not as deep as the Onyx Studio 7.
Buy the B&O Beolit 20. It is rated higher for sound quality and still sold new, while the Teufel Boomster NG (2017) is discontinued.
Battery life favors the Teufel Boomster NG (2017): rated for 18 hours against 8 hours for the B&O Beolit 20.
