The 8 speakers we track publish 12–30 h of battery and weigh 550–3,000 g — and every one carries an IP code that most listings never explain. Here is the decoder ring.

The decoder ring
An IP rating is two digits: the first is dust, the second is water. An X means "not rated for that half" — so IPX7 promises immersion survival (1 m for 30 minutes) but makes no dust claim at all, while IP67 adds dust-tight sealing on top of the same immersion rating. IP56, the odd one out in our set, trades immersion for high-pressure spray resistance with partial dust protection.
Match the code to the accident you actually expect: poolside dunks and beach sand point to IP67; a shower shelf is fine at IPX7; a patio speaker that meets sprinklers and dust storms is what IP56 is built for.
The playlist math
Every manufacturer rates battery life at moderate listening levels, and every battery shrinks when the speaker is pushed to party volume — by how much is rarely published, so we score the rated figure and flag the caveat instead of inventing one. Our tracked set runs 12–30 h.
For day-long outings, 20-plus rated hours is the comfortable band; the 12 h end of our set is a picnic speaker, not an all-day camper. Off-grid weekends put power on the packing list too — our camping fridge and portable power station comparisons cover the rest of that kit.
The size question
Rated output in our set spans 20–80 W among the brands that publish a figure — and watts alone do not predict loudness, because driver area and enclosure volume do much of the work. What watts do signal is intent: 20 W is a personal speaker, 80 W is built to carry a yard.
Weight draws the same map: our set runs 550–3,000 g, from a 550 g sling-anywhere cylinder to 3 kg movers with handles. Buy the heaviest speaker you will genuinely carry — the best-sounding speaker is the one that actually leaves the house.
