Rockville RPB-XL Portable Bluetooth Boombox — 18W Bass / 12W Treble, USB/TF/Aux, Powerbank, TWS

Compact yet powerful boombox with oversized driver delivering strong low end and clear highs — 18W RMS for the low frequencies and 12W for crisp highs, designed for music lovers who want volume and punch. Built-in 7.4V/4000mAh rechargeable battery provides extended playtimes: up to 32 hours at 20% volume, about 16 hours at 40%, or roughly 5 hours at maximum output; battery status is shown by 5 LED indicators. Connectivity includes Bluetooth via an Actions 4.2 chipset for stable, high-quality streaming from phones, tablets, or laptops with a wireless range of about 33 feet, plus hands-free calling. Playback and charging options are flexible — one USB port supports audio playback from TF cards or USB sticks (supports up to 64GB) while the second USB functions as a powerbank to charge your devices. For a wider soundstage, you can wirelessly link two RPB-XL units in True Wireless Stereo (TWS) mode to create left/right stereo separation for parties or home use.
