Retevis RB37 Bluetooth FRS walkie-talkie is a license-free two-way radio set sold as a 4-pack with paired Bluetooth microphones. Each radio auto-connects to its mic on power-up, and the mic's 40mm speaker keeps calls loud and clear in busy sites.
Built for camping, security and business use, the radios have a simple body with flashlight, emergency alarm, VOX, noise reduction and low-battery reminder. Each handheld runs on a 2000mAh battery for about 24 hours with its own charging base, while each mic runs about 12 hours on a 1000mAh cell charged by USB-C.
