JBL Charge 4 Portable Waterproof Wireless Bluetooth Speaker - Renewed

Our review of the JBL Charge 4 (Renewed) finds it best for buyers who want a rugged portable speaker that balances strong sound, long battery life, and simple Bluetooth pairing. The single biggest reason to consider this model is its combination of a high-capacity rechargeable battery and waterproof construction, which makes it especially suitable for outdoor use and long listening sessions. This review looks at real-world performance, battery behavior, connectivity, and build quality so you know what to expect from a renewed unit.

Key Features

• Dual device pairing: Allows two smartphones or tablets to connect and take turns, which is convenient for shared listening without re-pairing each time.
• Long battery life: The built-in rechargeable li-ion 7800mAh battery supports up to 20 hours of playtime, reducing the need to recharge during multi-day outings.
• Device charging: The speaker can double as a power bank, letting you charge a phone from its USB port when you need extra runtime away from an outlet.
• Waterproof design: Rated for use at the beach or pool, it survives spills and brief submersion so you can worry less about moisture during outdoor use.
• Expandable sound: JBL connect+ lets you wirelessly link more than 100 compatible speakers to amplify audio for larger gatherings.
• Wireless and wired connectivity: Bluetooth and USB options give flexible ways to play music from a range of devices.

Who It's For

This speaker is ideal for people who prioritize portability and battery life: hikers, beachgoers, and small-group hosts who want dependable sound without frequent charging. The waterproof build and rugged feel make it a practical choice for outdoor activities and casual poolside use.

It is less suitable for audiophiles seeking studio-accurate sound or buyers who need the latest wireless codecs and ultra-low-latency connections for gaming. Also, those who require guaranteed brand-new packaging or factory seals may prefer a new retail unit instead of a renewed item.
