Rockville RPB-XL Portable Camo Bluetooth Speaker Boombox USB/Powerbank/SD/Aux

The Rockville RPB-XL portable Bluetooth speaker is designed to deliver powerful sound performance in a rugged and travel-friendly boombox format. This extra-large portable speaker uses a dedicated amplifier channel for low frequencies along with separate amplification for high frequencies, producing balanced sound with strong bass output and clear highs.

Dual passive radiators help extend low-frequency response beyond what is typically expected from a portable speaker of this size. Wireless audio streaming is supported through Bluetooth connectivity, while True Wireless Stereo linking allows two RPB-XL speakers to be paired together for left and right channel stereo playback. Multiple playback options include USB audio, TF card support, and a 3.5mm auxiliary input for connecting external devices.

Dual USB ports allow one connection for music playback and another for charging compatible mobile devices. The built-in rechargeable 7.4V lithium-ion battery supports long listening sessions and features LED indicators to display remaining battery life. Integrated playback controls and a built-in microphone allow users to manage music and phone calls directly from the speaker. With a durable enclosure, rubberized carry handle, and compact footprint, the RPB-XL is suitable for indoor listening, outdoor use, and portable entertainment setups.
