Klein Tools AEPJS3 Bluetooth Jobsite Speaker — Magnet Mount, Hook, 20-Hour Runtime, USB-C/USB-A

Meet the Klein Tools AEPJS3 Bluetooth Jobsite Speaker, a compact yet capable companion built for demanding environments. Its 10W dynamic driver paired with a dedicated passive radiator delivers clear highs and convincing bass, making music, podcasts, or progress updates easier to enjoy during a hard day on site. The device is designed to travel with you, offering versatile mounting options and real-time flexibility so you can choose how and where you listen while you work.

Beyond sound, the AEPJS3 doubles as a power bank with USB-A and USB-C charging ports, allowing you to fuel essential devices when outlets are scarce. Its rugged, IP54 rating protects against dust and water splashes, and the enclosure includes drop protection up to 2 meters, making it well suited for busy workshops, outdoor sites, or busy job sites where gear takes a few bumps. This speaker isn’t just about listening; it’s about keeping momentum going when you need it most.

Flexible mounting and hands-free use

The product combines an integrated hook for hanging on nails or screws with embedded magnets for secure mounting to metal surfaces. This versatility means you can position the speaker exactly where you need it, whether it’s mounted above a workbench, attached to a metal cabinet, or hung from a ceiling hook for better coverage.
