These are not really the same size class, and that is the honest framing here. The Onn XL Wireless Party Speaker ranks #11 of 46 party speakers by sound quality at $249; the Teufel Rockster Air ranks #11 of 16 battery-powered PA speakers by sound quality.
The Onn XL Wireless Party Speaker is the tougher option. A compelling all-in-one party and karaoke package: dual 8-inch woofers, 240W claimed output, two included wireless microphones, dual mic/guitar inputs, karaoke effects and USB-A phone charging. It is rated IPX4, while the Teufel Rockster Air has no water resistance. It has an adjustable EQ, which the Teufel Rockster Air lacks. Watch for: Sound favors punch and a forward/bright top end over refinement.
The Teufel Rockster Air is the longer-running option. Exceptional 58-hour battery (31 hours at full volume with ECO mode). It is rated for 30 hours of battery against 16 for the Onn XL Wireless Party Speaker. Watch for: Peaky midrange, not very natural sounding.
One note: the Teufel Rockster Air is no longer in production and isn’t widely stocked new anymore. The Teufel Rockster Air’s replacement, the Teufel Rockster Air 2, is still sold new.
Buy the Onn XL Wireless Party Speaker for a party speaker, or the Teufel Rockster Air for a battery-powered PA speaker instead.

The Two Speakers In Full
Onn XL Wireless Party Speaker: $249.00 Walmart $249.00 eBay
Pros: A compelling all-in-one party and karaoke package: dual 8-inch woofers, 240W claimed output, two included wireless microphones, dual mic/guitar inputs, karaoke effects and USB-A phone charging. It plays loudly enough for backyard use and has punchy bass; owners especially like the wheels, telescoping handle and colorful light effects. At 44 lb it is still a substantial cabinet, but the trolley design makes moving it far easier than carrying it.
Cons: Sound favors punch and a forward/bright top end over refinement. Independent comparisons and owner reports find the bass less deep and the overall balance less satisfying than the JBL PartyBox 320; several consider the far-cheaper Onn Large Party gen 2 the better sound-per-dollar buy. Some owners report distortion or static at high volume, and a few report wireless-mic pairing/dropout problems. Large (30 inches tall, 44 lb) and only IPX4 splash-resistant, not a speaker to leave out in rain.
