Retevis Walkie Talkie Review: H777, RT22, RT29 and RB48 Compared

What to look for in a Retevis walkie talkie

Output power and real range

Retevis lists “5-mile range” on half their boxes. That number assumes you’re standing in an open field with no obstructions. In a city or a building, cut that by 70%. The H777 and RT22 both run around 2W in practice — expect 0.5 miles in urban conditions, up to 2 miles in open terrain. The RT29 runs 5W and gets closer to 2 miles in a city, 5 miles in open fields. For anything beyond 2 miles you’re looking at GMRS radio service radios with a license, not standard FRS.

FRS vs non-FRS models

Most Retevis handheld radios sold in the US operate on FRS frequencies — 22 channels, no license required. The RT22, RT628, and RB48 are certified FRS. The H777 is technically UHF and not FRS-certified, which means it operates in a legal gray area for US consumers. The RT29 is a higher-power radio that requires GMRS licensing at 5W. Know which category your radio falls into before you buy.

Battery type

Retevis models split between Li-ion rechargeable batteries and AA battery models. The RT22 and H777 use rechargeable Li-ion packs with a charging cradle. The RT628 runs on 3 AAA batteries — good for emergencies, bad for daily use. The RB48 charges via USB-C directly, which is the most convenient option for a work crew. If you’re running radios across two shifts, get the RT29’s 2800mAh pack — it’ll run 20 hours before you need to swap.

Earpiece compatibility

This trips people up. Almost every Retevis radio uses a 2.5mm single-pin audio jack — not the 3.5mm you’re used to. Standard earbuds won’t fit. You need a 2.5mm surveillance kit or acoustic tube earpiece. Retevis sells their own earpieces that are model-specific, but any 2.5mm walkie talkie earpiece will work. The RT29 is the exception — it uses a Kenwood-compatible 2-pin jack, so you have a lot more third-party options. I have a full breakdown on the walkie talkie earpiece page if you need specifics.

Durability and IP rating

The H777 and RT22 are both plastic with no official IP rating. They handle drops and light dust but don’t trust them anywhere near water. The RT29 carries an IP67 rating — fully dustproof and survives 30 minutes at 1 meter underwater. If your job involves rain, mud, or anything wet, the RT29 is the only Retevis model worth considering.

Channel lock and VOX

VOX (VOX hands-free operation) is a feature on most Retevis radios that auto-transmits when you talk. It sounds useful. In practice, the sensitivity is hard to tune and it picks up background noise constantly. I recommend leaving it off unless you’re in a hands-free situation where you physically can’t press the PTT button. Most radios let you disable VOX via a menu setting — hold the Menu button, navigate to VOX, set it to 0 or OFF.

The RT22 is the radio I hand to people who just need it to work and don’t want to think about it. No display, no confusing menus — just power on, set the channel, and talk. At $35 for a 6-pack it’s the best per-radio price in the Retevis lineup.

The range is honest for 2W FRS. In an open parking lot I got just over half a mile before audio started breaking up. Inside a concrete warehouse I could reliably reach across two floors — maybe 400 feet. Don’t expect more than that. But for what most crews use a walkie talkie for, this is enough. It rides all 22 FRS channels and the 121 privacy codes (CTCSS tones) keep your crew off other channels in a busy venue.

Battery runs about 12 hours on a charge. The charging cradle accepts up to 6 radios at once, which matters when you’re storing a fleet overnight. The 2.5mm earpiece jack is the only pain point — standard earbuds don’t fit, so budget for a compatible surveillance earpiece if you need hands-free.

• $35 for 6-pack — unbeatable per-radio cost
• 22 FRS channels, no license needed
• Multi-unit charging cradle included
• Simple operation, no training needed
• Belt clip included on every radio

• 2.5mm earpiece jack, not 3.5mm
• No IP rating — not waterproof
• No display (can’t see which channel you’re on)
• Range drops significantly indoors

Bottom line: Best Retevis walkie talkie for price-conscious buyers and light-duty use. If you’re equipping a retail team, event staff, or family outing — this is the one to buy.

Honestly? The H777 is the radio that made Retevis a name people recognize. It’s been selling since 2015 and it’s still the cheapest way to hand two people a working radio under $25. It’s not the best radio here. But it’s not bad either.

The H777 runs on 16 UHF channels in the 400–470MHz band. It’s not FRS-certified, which technically puts it in a gray area under Part 95 for US consumers. If you’re just using these on a job site or family hike and not broadcasting near air traffic, nobody is going to care. But know what you’re buying. The 2W real output gets you similar range to the RT22 — half a mile urban, 1.5 miles open. The 1200mAh battery lasts about 10 hours, less if you’re transmitting constantly.

Where the H777 falls behind the RT22 is build quality. The plastic feels cheaper, the buttons get stuck after heavy use, and the battery contacts corrode faster. For a construction crew running these 5 days a week, you’ll be replacing them within a year. For occasional use, they’re fine.

• Cheapest Retevis radio under $25 a pair
• Simple 16-channel operation
• Strong community — lots of user guides available
• Replacement batteries easy to find

• Not FRS-certified for US market
• Cheaper build than RT22
• Only 16 channels vs RT22’s 22
• No privacy codes (CTCSS tones)

Bottom line: The H777 earns its place as the entry-level pick for infrequent users and tight budgets. If you’re using these more than twice a week, step up to the RT22.

This is the radio for serious use. The RT29 runs 5W output with an IP67 waterproof rating and a 2800mAh battery that lasts a full double shift — I’ve run one from 7am to 10pm and still had charge left. Nothing else in the Retevis lineup comes close on any of those numbers.

The RT29’s range is the biggest gap versus the RT22. In an open field I consistently hit 5 miles before audio degraded. On a construction site — concrete, rebar, equipment noise — I got clean transmission at 2 miles across different floors of the same building. That’s genuinely useful. The RT22 gave up around 400 feet in the same building. For more information on how walkie talkie power affects range, see our walkie talkie range guide.

The IP67 rating means it survives rain, drops in puddles, and dusty sites without a second thought. The radio is heavier and bulkier than the RT22, which matters if your crew is carrying it all day. And the 5W output technically requires a GMRS license — something most job sites overlook but worth knowing. The two-pin Kenwood-compatible jack means you have far more earpiece and headset options than the 2.5mm Retevis standard.

• 5W output — double the range of RT22
• IP67 waterproof and dustproof
• 2800mAh battery, 20+ hour runtime
• 2-pin Kenwood jack — wide accessory compatibility
• LED flashlight built in

• 5W requires GMRS license in the US
• Heavier and bulkier than FRS models
• Higher price point ($50–$70 per radio)
• Only 16 channels vs 22 on FRS models

Bottom line: The RT29 is the only Retevis radio I’d run on a real job site. If you need range beyond a quarter-mile and can’t afford a dead radio mid-shift, this is your pick. See how it stacks up against other long-range walkie talkies.

The RT628 is not for adults. The power, the build, the battery — everything about this radio is tuned for occasional use by kids or casual hikers. And for that specific use, it does the job.

It runs on 3 AAA batteries, which is actually useful for emergency situations where you can’t charge. Range is limited at 0.5W — FRS Part 95 rules cap it — so expect 300 feet in a neighborhood, maybe half a mile in an open park. The buttons are big, the interface has two settings (channel and squelch), and there’s nothing complicated to configure. A ten-year-old can figure it out in two minutes. Check out our best walkie talkie for kids guide if this is what you’re shopping for — there are better options at this price point from other brands too.

• 3 AAA batteries — no charging needed
• 22 FRS channels, legal everywhere
• Extremely simple to operate
• Lightweight and small

• 0.5W output — short range
• AAA batteries drain quickly with heavy use
• Not suitable for professional use
• No earpiece jack

Bottom line: The RT628 earns its spot as a kids’ radio or camping backup. Don’t buy it for work.

The RB48 is where Retevis starts taking business users seriously. USB-C charging directly through the radio body — no separate battery pack to swap — plus a multi-unit dock that charges 6 radios overnight. That matters when you’re managing 10 or 20 radios for a team.

It runs 22 FRS channels at 2W with an IPX4 splash-proof rating. Not IP67, but enough to handle rain and spills. Range is similar to the RT22 — half a mile urban, up to 2 miles open. The 1500mAh battery gives about 15 hours on a charge. The display shows channel and battery status, which the RT22 doesn’t have. If your team needs to know which channel they’re on at a glance, the display pays for itself.

• USB-C direct charging — convenient
• Multi-unit charging dock available
• Display shows channel and battery
• IPX4 splash resistant
• 15 hours battery life

• More expensive than RT22 per radio
• IPX4 only — not submersion rated
• 2W range same as cheaper RT22

Bottom line: The RB48 is the right call for business teams managing multiple radios who want USB-C charging and a display. If you don’t need those features, the RT22 saves you money.

How to use a Retevis walkie talkie

Most Retevis radios work the same way. Here’s the standard setup procedure that covers the H777, RT22, RT29, RT628, and RB48.

Basic setup

Power on by holding the volume knob up (most models) or pressing the power button. Set both radios to the same channel. On the RT22 and RB48, channel changes are made with the up/down arrow buttons. On the H777, turn the channel dial at the top. On the RT29, use the side buttons and the display to confirm your channel selection.

How to change channels

RT22 and RB48: press the up arrow or down arrow button until your target channel appears on the display or is indicated by the LED indicator on the RT22 (which has no screen). H777: rotate the top knob clockwise or counterclockwise. RT29: short press the up/down keys on the side — the LED display shows the current channel number.

How to turn off VOX

On the RT22: hold the Menu key (3 seconds) — press Menu again to scroll to the VOX setting — use the up/down keys to set VOX to 0 — press PTT to save. On the RT29: same procedure, but navigate using the side keys and confirm with PTT. The H777 has no VOX function. The RT628 has no menu system at all.

How to change language

Some Retevis models include a voice prompt that reads channel numbers in Chinese by default. To switch to English: hold Menu — scroll to the Voice setting — select English — press PTT to confirm. This option only appears on models with a voice prompt feature (RT29 and some RT22 variants). If the radio has no menu system, there’s no voice prompt to change.

How to pair two radios

Retevis two-way radios work on shared channels, not paired connections like Bluetooth. Both radios must be on the same channel and the same CTCSS/DCS privacy code. Set both to Channel 1 (or whichever you choose), set the CTCSS code to the same value on both (or OFF on both), and press PTT. If the receiving radio’s squelch breaks, you’re connected. For a full explanation of how privacy codes work on two-way radios, see our guide on CTCSS privacy codes.

Retevis walkie talkie earpiece compatibility

Not all earpieces fit all Retevis radios. Here’s the breakdown:

The 2.5mm pin is the standard Retevis connector across most models. You’ll find acoustic tube surveillance earpieces in this format for $8–$15 on Amazon. The RT29’s Kenwood 2-pin compatibility opens up a much wider range of professional headsets, including full over-ear options for noisy environments. For detailed earpiece comparisons, see our walkie talkie earpiece guide.

Retevis walkie talkie channel frequencies

The RT22, RT628, and RB48 operate on FRS channels as defined by the FCC. These are the frequencies assigned to each of the 22 channels:

Channels 8–14 are FRS-only and limited to 0.5W maximum — that’s why the RT628 gets worse range when it defaults to those channels. Channels 1–7 and 15–22 support 2W on FRS and up to 50W on GMRS. For a full breakdown of all GMRS and FRS frequencies, see our FRS/GMRS radio frequency chart.
