Klein Tools AEPJS3 Rugged Bluetooth Jobsite Speaker & USB Power Bank

The Klein Tools AEPJS3 rugged portable Bluetooth jobsite speaker delivers 10 watts of crisp, high-fidelity audio across active construction jobsites, commercial service vans, and industrial fabrication shops. Engineered with a multi-port USB-A and USB-C power bank to charge smartphones, wireless headlamps, and small electronic gear, this wireless audio unit provides up to 20 hours of continuous runtime per charge. Outfitted with heavy-duty embedded mounting magnets for secure attachment to steel electrical panels and toolboxes, an integrated wire hanging hook, IP54 dust and water resistance, and Broadcast Mode to pair up to four additional units, it equips electricians, mechanical contractors, and tradespeople with versatile audio streaming and mobile device charging.
