Short answer: the Soundboks 4 for raw battery-powered output, the Bose S1 Pro+ for a compact PA. The Soundboks is tied for the loudest battery-powered speaker and carries a removable 40-hour battery, but it is very large, not stereo and behind the top Partyboxes on neutrality and bass. The Bose is compact and light with crystal-clear audio and a real three-channel mixer, though full-range music distorts above about two-thirds volume.
Buy the Bose S1 Pro+. It is rated higher for sound quality than the Soundboks 4 and costs less, which makes it the one to get unless you need something the other one does better.
If battery life is a priority, the Soundboks 4 is rated for 40 hours versus 11 hours for the Bose S1 Pro+.
Water resistance is not close: the Soundboks 4 is rated at IP65 (water jets), well ahead of the Bose S1 Pro+ at no water resistance.
