Best for the default right answer
JBL Flip 7
The size the category settled on, with the highest ingress rating here and a battery that covers a full day outdoors.
This is the size the whole category has converged on, and the Flip has been the reference point for several generations. The seventh version's meaningful change is the ingress rating: IP68 means it is rated for immersion beyond the one meter for thirty minutes that IP67 covers, which in practice means a kayak day or a rainstorm on a picnic table is a non-event rather than a worry.
Treat the battery number the way you treat a car manufacturer's range figure. Fourteen hours is at moderate volume; outdoors, where you turn everything up because there are no walls to reflect sound back at you, it is less. The Playtime Boost mode buys more hours by cutting the low end, which is a genuinely useful option on a long weekend and not something you want on day one. If you want music and a phone charger from the same object, the Charge below does that and this does not. See <a href="/road-trip/best-road-trip-gadgets">road trip gadgets</a> for the rest of the car kit.
Specs
- IP68 rated for dust and water
- Manufacturer-quoted 14 hours, extendable with JBL's Playtime Boost mode
- Cylindrical body, stands upright or lies flat
- USB-C charging; Auracast multi-speaker pairing
Good for
- IP68 rather than IP67 -- the difference is depth and duration, and it is the highest rating on this page
- The cylinder shape fits a car door pocket, a cup holder and a side pocket on a pack
- Playtime Boost trades some low end for extra hours, which is the right trade on day three
Bad at
- Bass is modest for the size; it is a clear speaker, not a loud one
- Playtime Boost noticeably thins the sound, so the headline battery figure is not the figure you will hear
- Nothing to clip it to without buying the accessory strap
