Short answer: the JBL Partybox On the Go. It ranks #46 of 75 boombox speakers by sound quality at $300; the Demerbox DB2 ranks #51 and costs $400, so there is little reason to consider the other one.
What the JBL Partybox On the Go offers: JBL Partybox On the Go uses 5.1” woofer + tweeters. Its 7.5 kg, claimed 6 hours (Manufacturer specified) battery life, IPX4 protection, aux input, up to 94dB and limited-stereo playback make it a practical option for its intended room or portable use. Watch for: Bass is limited by its 49Hz specification. No EQ adjustment.
What the Demerbox DB2 offers: 40+ hour battery life even at higher volumes (real-world: ~14 hrs with phone charging mixed in). Built from a Pelican case - nearly indestructible and waterproof (IP67). Multi-pair up to 6 units. Doubles as power bank and waterproof container. Watch for: Bass is not as deep as better speakers. Very overpriced.
Buy the JBL Partybox On the Go. It ranks higher for sound quality than the Demerbox DB2 and costs less, which settles it without a real tradeoff to make.
There is a real battery-life gap here: the Demerbox DB2 is rated for 40 hours, the JBL Partybox On the Go only 6 hours.
There is a real gap in water resistance: the Demerbox DB2 at IP67 (brief submersion) against the JBL Partybox On the Go, which has IPX4 (splashing).
