JBL Charge 4 Waterproof Portable Bluetooth Speaker - Long Playtime

Our review of the JBL Charge 4 finds it is an ideal portable speaker for people who prioritize loud, clear sound and multi-day battery life without fuss. The Charge 4 pairs quickly with phones and tablets via Bluetooth, delivers prominent bass from dual passive radiators, and includes a built-in USB power bank so users can charge a phone on the go. Rugged fabric and an IPX7 waterproof rating make it suitable for outdoor use at the beach, pool, or on short hikes, and its ability to link with other JBL Connect plus speakers means it can scale for larger gatherings.

Key Features

• Wireless Bluetooth streaming: Lets two devices take turns streaming music for effortless sharing and quick re-connection.
• Up to 20 hours of playtime: The high-capacity rechargeable battery provides long listening sessions and can charge a smartphone via the USB output.
• IPX7 waterproof: The fully waterproof exterior tolerates spills and brief submersion so it holds up at the pool or beach.
• JBL Connect plus: Wirelessly links more than 100 compatible speakers to expand sound coverage for parties and outdoor events.
• Durable fabric and rugged housing: Tough construction resists everyday knocks and travel wear for reliable outdoor use.
• JBL bass radiator: Dual passive radiators deliver punchy low end that makes bass-heavy tracks sound fuller than expected for its size.

Who It's For

The JBL Charge 4 is best for listeners who want a portable, durable speaker that can be used outdoors and at social gatherings, and who value strong bass and long battery life in one unit. Its USB charge-out is useful for commuters or campers who need emergency power for phones.

People who need extremely compact pocket-sized speakers or those seeking the absolute latest Bluetooth codec support for audiophile setups may want to look elsewhere; the Charge 4 is focused on robust, full-range sound and practicality rather than being the smallest or most feature-packed high-resolution player.
