ACEFAST K3 Max Portable Waterproof Speaker

The ACEFAST K3 Max is a powerful and rugged portable Bluetooth speaker engineered for both indoor use and outdoor adventures. With a peak power output of 80 W (1×48 W + 2×16 W) and a rated continuous output of 40 W, it produces rich, room-filling sound with deep bass, clear mids, and crisp highs. The speaker features a 2.1-channel configuration — one mid-to-low driver, two tweeters, and a passive diaphragm — that delivers immersive 360° audio, amplified through a built-in DSP processor that optimizes clarity and balance across frequencies. It supports TWS (True Wireless Stereo) interconnection, so you can pair two K3 Max units for stereo surround sound. For customizing your listening experience, it offers three EQ modes (Music, Movie, Party) and dynamic RGB lighting effects (constant, breathing, flashing) to match the mood. The speaker runs on a 5,000 mAh battery, giving up to 20 hours of playtime per charge and recharging in roughly 6 hours via USB-C. Built for portability, it includes a textured silicone strap, anti-slip pads, and weighs about 1.43 kg, while its durable build with metal mesh and IPX6 water resistance makes it splash- and sweat-proof for outdoor settings. You can also play music from a USB flash drive, TF card, or AUX line-in, and there’s a built-in HD microphone for hands-free calls.
