Retevis RB48 Review: Worth It? (November 2026)
The Retevis RB48 is a buy for crews that need gloved-hand PTT and weatherproof FRS radios, since the four-pack pairs a 22-channel FRS set with IP67 sealing and 2000mAh batteries. Skip it if you only need two radios or want a radio that talks straight to an RB48 Plus without a menu change.

The Retevis RB48 is a buy for work crews that need a tough, gloved-hand FRS radio set, and the four-pack makes sense when you're equipping a small team. Its front PTT, IP67 sealing and long battery life fit construction, landscaping and outdoor jobs better than most consumer FRS pairs.
This Retevis RB48 review walks through what the radio offers, how it sets up and where the four-pack format gets in the way. If you want two radios for casual walks, this is more kit than you need.
If you're handing radios to four people who wear gloves and work outdoors, it's a strong fit.
Retevis RB48 at a glance
The RB48 is a 22-channel FRS radio sold as a four-pack, built around durability and easy use with gloves. Retevis rates the shell to MIL-STD-810H and IP67, and each radio carries a 2000mAh Li-ion battery that the maker says lasts up to 20 hours.
Retevis RB48 FRS Walkie Talkies, 4 Pack: Best for gloved jobsite crews
- IP67 waterproof, 1 m for 30 minutes
- MIL-STD-810H durability
- Large front PTT and dual PTT
- 2000mAh battery, up to 20 hours
- 22 FRS channels
- NOAA weather alerts
- Vibration alerts
A four-pack of FRS radios built for gloves and bad weather. The front PTT, IP67 shell and long battery cover most outdoor team needs.
Pros
- Glove-friendly front PTT
- IP67 water and dust sealing
- Up to 20 hours per charge
- NOAA weather alerts and vibration alerts
- 5-year radio body warranty
Cons
- Four radios may be more than a small pair needs
- CTCSS/DCS settings must be turned off to talk to an RB48 Plus
The radio measures 1.3 in deep, 2.4 in wide and 7.1 in tall, so it's a full-size handheld rather than a pocket unit. That size is what makes room for the large front PTT button and the dual PTT design, which are the features most buyers will notice first.
Retevis puts the coverage at up to 300,000 square feet and 25 floors. Those are open-area figures, and the maximum talking range is 3 miles.
Treat both as best-case numbers for clear, open ground. The set weighs about 730 g, and each unit runs on a 3.7 V pack.
The yellow shell helps you spot a radio on a crowded bench or in tall grass. One order covers a four-person team without buying pairs twice.
Who the Retevis RB48 suits
This radio is best for small work crews, outdoor teams and event staff who need to talk without taking off gloves. The front PTT sits where a thumb naturally lands, and the oversized button works with a bare hand or a work glove.
The dual PTT gives a second talk path for a second channel without a menu dive, which suits a team that runs a main call channel and a separate one for the foreman or dispatch point.
It also fits anyone who works in wet or dusty conditions. The IP67 rating covers rain and splashes, and the dust sealing is tested against fine particles.
A landscaping crew, a construction site or a wet-weather event setup is the natural home for this set.
Skip it if your group is two people on a weekend hike. Four radios plus two charging docks is more hardware than a pair of casual users needs, and a smaller FRS pair will cost less.
For that kind of trip, the walkie talkies for hiking roundup covers lighter options. The same advice applies to a couple who only needs to stay in touch across a campsite.
Specs that matter in daily use
The features that carry the RB48 day to day are the PTT layout, the battery and the sealed shell, not the channel count. FRS gives you 22 channels, standard for this class and enough for most teams.
The radio also carries NOAA weather alerts and a vibration alert, so it can double as a storm warning device for a crew that works outside.
The 2000mAh battery is the standout number. Retevis says a full charge gives up to 20 hours of use, and the battery average is 18 hours.
For a workday that means one charge covers a full shift with room to spare, and the two charging docks let you rotate pairs. The 2000mAh pack is included with each of the four radios, so the set is ready once you charge it.
The dual PTT design is useful when different tasks need different calls. The large front button handles the main channel, and the second PTT gives a separate talk path without changing channels.
Vibration alerts help when the radio sits in a pocket or on a belt and you can't hear the speaker. Retevis lists this as a heavy duty FRS radio for construction, and the big button, belt clip and vibration alert are what make that label fit.
NOAA weather alerts are built in, so the radio can warn the team about storms, which is a real safety feature for anyone working outside.
Setting up the Retevis RB48 four-pack
Start by charging all four batteries in the two docks before the first shift. The set includes two charger adapters and two charging docks, so plan to charge in pairs and keep the other two radios in service.
USB-C on the radios means you can also top up from a power bank or truck outlet when the docks aren't nearby.
Fit the belt clips before you hand radios out, since a clip that's loose on a belt is easy to lose in the field. The yellow shell makes a dropped radio easier to find under a truck seat or in a pile of gear.
If your team also runs RB48 Plus radios, set the RB48 to match. The two models ship with different CTCSS/DCS privacy settings, so they won't talk out of the box.
In direct call mode, press MENU twice and turn the CTCSS/DCS number to 00, and the radios can reach each other directly. Our Retevis RB48 vs RB48 Plus comparison covers that difference in full.
If the radio seems to transmit without anyone pressing the button, VOX is on. Press MENU four times in standby, find VOX on the screen and set the level you want.
The vibration reminder is set the same way: press MENU eight times, pick ON or OFF, then save with PTT.
Care and weatherproofing in real conditions
The RB48 is built to take rain, dust and drops, and the care routine is mostly about keeping the seals and battery contacts clean. Retevis rates it at IP67, which means it withstands 1 m of water for 30 minutes.
That's rain and puddle-proof, not dive-proof, so don't leave it sitting in water. Retevis also describes a floating design, which matters when a radio goes overboard on a wet job.
Retevis says the shell passed an 8-hour sealing test against fine dust and 1,000 drops from 2 m without breaking. The RB48 also passed 19 durability tests, including temperature shock, salt fog, humidity, sand, vibration and immersion.
The PC and TPE shell is chosen to stay tough in heat and cold. Those are maker claims, but they describe a radio meant for rough handling.
Keep the battery contacts and charging pads clean and dry. Wipe the shell with a damp cloth and dry it before charging.
A dirty contact can stop a charge from taking, which is the most common way a sealed radio fails in the field. There's also a protective plastic film on the LCD when the radio arrives.
Peel it off, and the screen is easier to read in sunlight. The RB48 also carries a 5-year warranty on the radio body and a 1-year warranty on accessories.
Beyond the warranty period, Retevis says it still offers maintenance for a cost.
Trade-offs before you buy the four-pack
The biggest trade-off is the four-pack format itself. If you only need two radios, you're paying for two spares and a second charging dock.
The upside is that the spares stay charged and ready, which is worth it for a crew that runs radios all day. The docks charge in pairs, so a full set of four takes two rounds unless you also use the USB-C ports.
The second trade-off is compatibility with the RB48 Plus. The two radios don't match on privacy codes until you set the RB48 to 00, so a mixed set takes a minute of menu work before the first call.
The same privacy settings matter when you talk to other FRS radios on the same channel, so keep a note of the codes your team uses.
Range is the third limit. The 3-mile maximum is a best-case figure, and FRS radios lose distance quickly in dense woods, between buildings or across floors.
The 300,000 square feet and 25 floors figures assume open space. Plan coverage around the real terrain, not the box numbers.
Finally, compare what two pairs would cost before you decide the set is the better deal, and weigh that against the two docks and spare batteries you get here.
Alternatives to the Retevis RB48
The RB48 is a strong jobsite radio, but it isn't the right set for every trip. These three uses point to different priorities.
For a cruise ship
A cruise ship puts radios on steel decks and between cabin floors, so a set tuned for indoor range and simple charging beats a rugged jobsite build. The RB48's sealing and battery life still help on deck, but its four-pack size and front PTT are more than a family on vacation needs.
If your trip is a cruise, the walkie talkies for cruise ship roundup covers sets built around shipboard use. The sealed shell and vibration alert matter when a radio sits in a beach bag and the speaker is muffled.
For hiking
On a trail, light weight and long battery life matter more than gloved-hand controls. The RB48's 2000mAh battery and NOAA alerts fit a day hike well, and the IP67 shell handles rain.
The 22 FRS channels also keep you clear of busier family bands on a crowded trailhead.
For lighter packs and simpler pairing, the walkie talkies for hiking guide compares options. The RB48 makes most sense when you're outfitting a group, since a set of four covers two hiking pairs and the spare pair stays charged at the trailhead.
For skiing
Cold weather and gloves are where the RB48 earns its keep. The front PTT works with ski gloves, the IP67 shell handles snow, and vibration alerts help when the radio is zipped in a jacket.
The sealed shell also shrugs off the wet snow that gathers when a radio is set down on a lift or in the lodge.
The walkie talkies for skiing roundup covers sets built for the cold. If your group skis together and needs four radios, the glove-friendly design is the reason to pick it.
Verdict: is the Retevis RB48 worth it?
The Retevis RB48 is worth it for a small crew that works outdoors, because its glove-friendly PTT, IP67 shell and long battery life are built for that job. The four-pack format also means everyone on a four-person team gets a radio and a spare battery in rotation.
The MIL-STD-810H rating and 19 durability tests back that up on paper, and the 5-year radio body warranty makes the set a longer-term buy than a typical consumer pair.
Buy it if you need four rugged FRS radios for construction, landscaping, events or winter sports, and you want weather alerts and long battery life in one set. The included batteries, docks and belt clips mean the set is usable straight from the box once charged.
Skip it if you only need two radios for casual walks or a family trip. A smaller FRS pair will do that job for less, and the RB48's front PTT and four-pack size are more than a light trip needs.
Also skip it if your team already runs RB48 Plus radios and you don't want to change privacy settings on the RB48 before the first call. Check the channel and privacy settings you need before you order, and the rest is a straightforward handoff to your team.
Frequently asked questions
Is the Retevis RB48 really waterproof?
Retevis rates the RB48 at IP67, which means it is sealed to withstand 1 m of water for 30 minutes. That covers rain, splashes and brief drops in puddles, but it does not mean you should leave the radio submerged or use it for diving.
Does the Retevis RB48 need a license to use?
No. The RB48 runs on FRS channels, and FRS needs no license for personal or business use in the US.
Stay on the FRS channel and privacy settings, and keep in mind that FRS power limits keep the practical range short.
How far do the Retevis RB48 radios reach?
Retevis gives the RB48 a maximum talking range of 3 miles. Real distance depends on terrain, so expect less in dense woods or between floors and more across open ground with clear line of sight.
Why won't my Retevis RB48 talk to an RB48 Plus?
The two models ship with different CTCSS/DCS privacy settings, so they won't match on the same channel out of the box. In direct call mode, press MENU twice and set the CTCSS/DCS number to 00 on the RB48, and the radios can talk directly.
What comes in the Retevis RB48 four-pack box?
The set includes four RB48 radios, four 2000mAh Li-ion batteries, two charging docks with charger adapters, belt clips and a user manual. That setup lets you charge two radios at a time while the other pair stays in service.
