Charging in Your Vehicle
The Bass50 includes a 12V vehicle charger for use with your car’s accessory outlet (formerly known as the cigarette lighter).
To protect your vehicle's battery, charging only begins when the vehicle is turned on and the system voltage reaches 12.4V. This prevents draining power when the engine is off.
Using the External Battery Charger
Want nonstop bass for long events or multi-day trips? Add an external battery charger (sold separately) to your setup. It allows you to charge a second Bass50 battery outside the unit—perfect for quick swaps and continuous play.
Final Notes
- The Bass50 is a wireless, battery-powered subwoofer, and you won’t need to keep it plugged in to use it.
- Always use Trulli-approved chargers and cables to ensure safe and reliable performance.
