It features a high-capacity internal lithium-ion battery that delivers up to 10 hours of continuous playtime on a single charge.

Frequently Asked Questions
Can I use the speaker while it is plugged into the wall? Yes. The TX412B operates perfectly on standard IEC mains power, which also charges the internal battery while the unit is plugged in.
How long does it take to fully charge? A full charge typically takes around 4 to 5 hours when the unit is powered off.
Is it waterproof for outdoor use? No. While it is perfect for outdoor events, the TX412B is not water-resistant. We recommend using a specialized speaker cover if there is a risk of light rain or moisture.
