The Acefast K12 Air Portable Wireless Speaker delivers flexible audio for home and outdoor listening. Choose from BT streaming, AUX input, TF card playback, or TWS pairing to enjoy music your way. The speaker supports MP3 and WAV files from a TF card up to 32GB, while BT v6.0 provides a stable connection with a transmission distance of ≥10m. Its proprietary low-frequency algorithm produces powerful, punchy bass even at low volume levels. With 16W peak power, one full-range speaker unit, and two diaphragms, it delivers room-filling audio from a compact portable design. RGB lighting adds a visual element to playback, and the included lanyard makes carrying or hanging the speaker convenient. Two EQ modes let you switch audio settings for relaxing at home or adventuring outdoors. TWS pairing links two speakers for true stereo sound and a richer, more immersive listening experience. The single-mic AI call noise cancellation algorithm filters background noise and enhances voice quality for calls in busy or windy environments. A 3.7V / 1800mAh battery provides up to 7 hours of music time and up to 9 hours of call time under the stated test conditions. The upright design stays firmly in place during playback, while the IPX4 waterproof rating supports portable use. With USB-C charging and a charging time of about 3 hours, the Acefast K12 Air is designed for versatile listening at home and on the go.
