The maximum volume can cut through most ambient noise and easily cover a small construction site or gathering area, allowing you to enjoy a powerful and authentic listening experience even in noisy environments.
• Dustproof, Drop-Proof Design & Low-Voltage Protection: Built with job-site-grade dustproof and drop-proof capabilities, featuring a rugged, shock-resistant construction. Suitable for a variety of environments including construction sites, garages, tool rooms, woodworking shops, outdoor barbecues, parties, and other outdoor settings. Built-in low-voltage protection chip automatically shuts off the speaker when the battery voltage drops below 16V, effectively preventing over-discharge damage and prolonging battery lifespan. No more battery anxiety – keep the music playing on the jobsite all day long.
• TWS Functionality & Bluetooth 5.4：Connect two speakers simultaneously for double the volume and an immersive audio experience. With advanced Bluetooth 5.4 technology, enjoy stable, lag‑free syncing–perfect for job sites, outdoor parties, or any space that needs powerful, room‑filling sound.
• Dual USB Charging Ports & Long Playtime: Features USB‑A and USB‑C ports for emergency phone charging – turning the speaker into a "mobile power station" on the job site. Insert a USB drive and it automatically detects and plays MP3/WMA music files – no Bluetooth needed. Perfect for users unfamiliar with wireless operation or as a backup audio source. Additionally, the ultra-low power design drains batteries much slower than ordinary speakers – enjoy up to 15 hours of playback.
