Retevis RB648A PMR446 Rugged IP67 Waterproof Heavy Duty Walkie Talkie
Built on the PMR446 platform, the Retevis RB648A is a professional heavy-duty two-way radio designed for construction sites, contractors, and business teams. Featuring two-way noise reduction, it suppresses background noise on both the transmitting and receiving ends for clearer voice communication in demanding environments. With IP67 protection, durable PC+TPE construction, and proven resistance to 1,000 drops from 2 meters, the RB648A is built to withstand tough working conditions. Its 2000mAh rechargeable battery provides up to 12 hours of runtime, delivering reliable communication throughout the workday.

Long-Range Communication
The RB648A delivers dependable long-distance communication across a variety of outdoor environments. With a communication range of approximately 0.8–1.6 km in urban areas, 1.2–1.9 km in suburban settings, and up to 3 km in open outdoor areas, it helps keep teams connected across wider spaces—from hiking trails and campsites to large outdoor worksites and remote areas.

Two-Way Noise Reduction
The RB648A features advanced two-way noise reduction, filtering background noise on both the transmitting and receiving ends. From construction equipment and heavy machinery to noisy outdoor environments, it helps reduce distractions and keeps team communication clear and easy to understand.
Professional Rugged Protection (IP67)
Built to handle water, dust, and accidental drops, the RB648A meets the IP67 protection standard. It can remain submerged in up to 1 meter of water for 30 minutes and withstand exposure to dust and debris. Drop-tested from 2 meters for 1,000 times, this durable construction helps the radio remain operational through demanding daily use.
Long Battery Life
A built-in 2000mAh rechargeable lithium battery gives the RB648A up to 12 hours of continuous operation. With enough power to support extended shifts, it reduces the need for frequent charging and keeps teams communicating throughout the workday.
Easy Operation
Stay focused on the task with hands-free VOX communication and dual PTT buttons. The RB648A lets you switch effortlessly between voice-activated and push-to-talk operation via intuitive controls — even while wearing gloves.

Oversized PTT Button
Easy-to-press even with gloves. Dual PTT buttons for flexible, efficient operation on the job.

Floating Design
The RB648A floats effortlessly on water, making it ideal for beach trips, kayaking, boating, and other water activities. If it accidentally slips into the water, its buoyant design keeps it visible and easy to retrieve, helping reduce the risk of loss or water-related damage.

Emergency Alarm
The RB648A supports both local and remote emergency alerts for faster team response. With one press, users can activate a loud local alarm while simultaneously sending an alert to teammates on the same channel, helping quickly draw attention to emergencies and improve on-site safety.
