JBL Boombox 4 portable Bluetooth speaker
A larger portable Bluetooth speaker for gatherings at home, outdoor meals and situations where a compact pocket speaker is not the right size. Its carrying handle helps with moving it between locations. Choose it by the space available and how often you need to carry it, rather than battery life alone.
Published specifications
| Playback | Up to 28 hours; Playtime Boost adds up to 6 hours |
|---|---|
| Protection | IP68 water and dust resistance |
| Wireless pairing | JBL Auracast multi-speaker connection |
Battery life: what does the maximum mean?
JBL states up to 28 hours of playback, with up to 6 additional hours using Playtime Boost. The combined maximum is not the normal-mode battery rating. Runtime depends on volume, audio content and settings; these are manufacturer figures, not an Elechid battery test.
Check before buying
For stereo playback, confirm the exact two-speaker combination in the JBL instructions. Auracast multi-speaker connection should not be assumed to work with PartyBoost or Connect+ speakers. Check the required carrying accessories and charging equipment against the supplied package.
Water-resistance ratings apply under the manufacturer’s specified conditions. Keep the charging connector clean and fully dry before charging; do not interpret the rating as protection in every liquid or situation.
