What to know before buying

Listing details to confirm

Battery claims differ: the details list 34 Hours, while the feature text specifies up to 28 hours of Bluetooth playtime plus an extra six hours with Playtime Boost. Treat these as mode-specific claims rather than one guaranteed duration. The listing also gives a 40 Watts maximum output while describing sound as bold and powerful without a comparable performance measure. Waterproof is listed, and the feature text also claims dustproof design, but no protection rating is supplied. Confirm the exact power cord and plug supplied for your region.

How long does the JBL Boombox 4 battery last?
