Features

5W GMRS Long Range: 30,000 sq.m, 30 Floors, 3-5 KM

The Retevis RB48 Plus GMRS walkie talkie has a maximum transmission power, making it a long-range two way radio. It offers a call distance of 30000sq.m, 30 floors, or 3-5KM, keeping constant calls even when you are away.

2000mAh Battery: Up to 18 Hours with Type-C Top-Ups

The Retevis RB48 Plus high power walkie talkie features a built-in 2000mAh battery, allowing continuous use for up to 18 hours. It supports type-C charging and charge stations. Power saving function can extend the life of your batteries.

IP67 Triple Proof: Waterproof, Dustproof, Drop-Tested

The RB48 Plus carries an IP67 rating: it survives 1 m of water for 30 minutes, seals out 0.1-micron dust, and has passed 1,000 drops from 2 meters without breaking. The PC + TPE shell adds grip and shock . For crews that lost radios to rain, grit, or a single bad drop, this is the spec that pays for itself in one season.

Glove-Ready Dual PTT: Front Giant Key Plus Side Key

Two transmit keys, two ways to talk: an oversized front button and a side PTT. The front key is sized for winter gloves, work gloves, or wet hands, while the side key suits a natural thumb grip when the radio rides in a hand. Crews that abandoned small-button radios will find this is the feature that keeps people actually pressing to talk.

One-Key Group Call Reaches the Whole Team

Long-press the group call key and every radio on the channel opens at once - no scrolling through member lists mid-incident. For parade marshals spreading volunteers along a 2 km route, or a job-site foreman calling breaks across crews, one-key group call turns a fifteen-second roll call into a single button press.

Vibration Alerts Cut Through Heavy Equipment Noise

VOX Hands-Free with 0-9 Sensitivity Levels

Set VOX once and the radio transmits when you speak - no button, no clipped words mid-lift. Tuning matters: sensitivity 9 grabs whisper-quiet speech for clean indoor work, while lower levels ignore background roar on sites. Electricians on ladders, kayakers with paddles in hand, and mechanics under a chassis are the crews who set VOX on day one and never go back.

Relay Channels: Extend Range Through GMRS Repeaters

Retevis RB48 Plus advanced triple proof 2-way radio has relay channels. The relay channels efficiently extend the call distance by connecting to the base station.

Three-Color LCD Shows Status at a Glance

The Retevis RB48 Plus with screen helps users check the working status of two way radio. Its three backlight colors refer to different statuses. The red is transmitting, the blue is receiving, and the purple is on standby.

2.5mm Single-Pin Jack Shares RB48 Accessories

The RB48 Plus uses the same 2.5mm single-pin jack as the RB48 line, so earpieces, speaker mics, and accessories already in your fleet plug straight in. Teams mixing RB48 and RB48 Plus units buy one accessory family instead of two, and replacements ship fast because the parts are shared across both models.

Battery Save Mode Stretches Standby Between Shifts

If you open RB48 Plus IP67 waterproof walkie talkie battery save mode, it can reduce battery power consumption, and conserve the battery power for a longer battery life.

Two Charging Ways: USB-C Anywhere or Dock Overnight

The Retevis RB48 Plus drop-proof radio has two charging methods,type-C charging and desktop charging. You can flexibly and conveniently choose the charging method to charge the walkie talkie for longer work time.

Anti-Slip PC + TPE Shell Grips Wet and Gloved Hands

Retevis RB48 Plus long range radio uses an anti-slip design, which reduces the damage to the walkie talkie because of slipping during use. It increases the stability and durability of two way radio.

Local and Remote Emergency Alarms for Lone Workers

The emergency alarm of the Retevis RB48 Plus anti-slip radio helps ensure your safety. Retevis RB48 Plus 2-way radio has two alarm modes, remote and local Alarm. In emergencies, long press the alarm key to turn on the alarm function to seek help.
