The Acefast K12 Pro portable wireless speaker delivers room-filling audio with 30W peak power for home, travel, and outdoor use. Its proprietary low-frequency algorithm provides powerful, punchy bass even at low volumes, while two EQ modes let you choose a mellow tone or a vibrant sound. Stream music wirelessly through BT v6.0, connect a USB flash drive or TF card up to 32GB, or use the AUX input. The speaker supports MP3 and WAV formats, so compatible files do not need conversion. A clear digital display shows the battery level, volume, track number, and current audio source in real time. The upright design stays firmly in place, and the included elastic carrying rope makes the speaker easy to carry or hang. Use TWS pairing to link two speakers for a true stereo experience with an expanded soundstage. Five vibrant RGB light effects add visual flair, including pulsating beat sync and calm ambient glow options. The high-capacity 2400mAh battery provides up to 8 hours of music playback at moderate volume and takes about 3.5 hours to charge fully. For calls, the single microphone with ENC and AI-powered call noise reduction filters background noise for clear voice transmission. BT v6.0 provides stable audio streaming with minimal interference and a transmission distance of at least 10m. With home and outdoor sound modes, multiple playback options, RGB lighting, and a compact 525g design, the Acefast K12 Pro is built for flexible listening.
