JBL Stage 310

The JBL PartyBox 300 is a large, high-output portable Bluetooth party speaker that delivers 240W of signature JBL sound with heavy, aggressive bass. Launched as an early foundational model in the PartyBox series, it features three eye-catching RGB light show modes (Meter, Pulse, and Party) and a massive 10,000mAh built-in battery providing up to 18 hours of playtime. While it lacks modern conveniences like water resistance, dedicated app support, and the telescopic handle/wheels found on newer iterations, it remains highly flexible for audio setups by offering physical mic and guitar inputs, a built-in USB power bank, True Wireless Stereo (TWS) pairing, and a unique 12V DC car input to power the speaker directly from a vehicle
