Acefast Portable Speaker K2 Pro

Experience cinema-grade sound anywhere with the ACEFAST K2 Pro portable wireless speaker. Delivering 120W peak power from 2×50W full-range and 2×10W high-frequency drivers, it fills rooms with powerful bass and crisp highs. A DSP processor, along with four speaker units and two diaphragms, creates rich, dynamic audio, while colorful RGB lighting adds party-ready visuals. When you pair two K2 Pros via TWS, you unlock 360-degree surround sound for a home theater–level KTV experience.

Rugged enough for travel and long sessions, the K2 Pro houses a 9600mAh battery for up to 10 hours of playback. It supports Bluetooth 5.3 with a range of about 10 meters, plus USB flash drive and AUX playback for versatile listening. USB-C input supports 5V/1A, 5V/2A, or 9V/2A charging, with a 2.5–4.5 hour recharge time. IPX5 water resistance, a convenient carry handle, and a compact footprint (386 x 197 x 152 mm, 3.1 kg) make it ideal for parties, outdoor gatherings, and on-the-go use.
