The Retevis RT21 combines simplicity, class and efficiency if we’re to go by the testimonies of verified users and our own experience. With 10 radios in the pack, this two-way radio product is rechargeable and is often prescribed for heavy-duty activities.

What’s more, it ranks very highly among portable walkie talkies on the market. The black exterior gives it a simple and serious look; a pointer that it is for adults and for serious business.

It is a pretty sturdy radio with multiple channels and considerable range for neighborhood use. It operates on the UHF band, giving it considerable penetration power through walls in buildings and other obstacles in the neighborhood.

A selling point is that the offer contains 10 packs, which can be used by 10 members of your team at a price that is largely unbeatable among its peers.

Retevis RT21 Walkie Talkie Review

This radio has a very long antenna, which is quite sturdy and won’t be damaged easily. This length also supports its range and signal quality.

When compared with other products within its category, the Retevis RT21 FRS walkie talkie has some pretty positive ratings that give it an edge over several competitors.

Frequency Details of Retevis RT21 Walkie Talkie

The Retevis RT21 radio operates on the Family Radio Service (FRS) Frequency over the UHF band. This means it comes ready to use and requires no license from authorities.

The UHF band also means it can penetrate through walls easily. While the radios are properly programmed to connect to themselves, you may require reprogramming to connect to other FRS/GMRS radios.

Also, because all the channels are assigned the CTCSS or DTC squelch code, you’ll need to reprogram other radios without squelch codes before they can work with these.

Range of Retevis RT21 Walkie Talkie

The maximum range of the Retevis RT21 is 2.5 miles. This can be achieved in an open area, without obstacles.

Within buildings, underground and from valley to mountain, this range can reduce significantly to a range between 0.5 miles and 2.5 miles.

So, if you’re using this in a building with multiple walls, you should achieve a range of just around 1 mile.

While this might be great within controlled spaces, you’ll lose track if you take this beyond reasonable limits.

How Long will Retevis RT21 Walkie Talkie’s Battery Survive?

The two-way radio is powered by 1,100 mAh lithium-ion battery that is fully rechargeable within 3 to 4 hours. Battery life is up to 12 hours of talk time.

This large capacity li-ion battery is secured with an aluminum plate which can dissipate heat easily. This makes it long-lasting and durable; it can survive a drop up to 2 meters.

Accessories of Retevis RT21 Walkie Talkie

  • Earpiece: The Retevis RT21 comes with a factory secret-service style earpiece that takes away the bulkiness of regular earpieces and gives you that class you desire. The earpiece is also discreet and has the capacity to prevent noise and distortion. The earpiece also has a mic for easy, hands-free communication.
  • Charging Base: With this design, the radio cannot be connected directly to a charger. The battery is detached and plugged in separately. If you have spare batteries, this means you can go ahead with your work while you charge a battery.
  • Belt Clip/Hand Strap: Depending on the kind of job you do; you may not be able to hold a walkie talkie as you move about. You need the hands-free advantage. This radio is equipped with both a belt clip and a hand strap, so you can easily fasten it on your waist, your chest area or on your arm.

Important Features of Retevis RT21 Walkie Talkie

1. Power-Saving Function

With a battery life already reaching 12 hours, the Retevis RT21 also has a battery-saving function which preserves battery power when the radio is not in use.

This can significantly increase talk time by several hours and reduce how often you recharge the battery.

2. Emergency Alarm

This is a great feature that every walkie talkie should have. Imagine you’re working construction and an accident occurs with no one close to you.

How do you call for help? You may also get trapped somewhere or be in some other kind of emergency. All you have to do is push the emergency button to alert other members of your team.

3. VOX Hands-free

The VOX hands-free function is another important feature that makes this radio very convenient for use.

In a restaurant, for instance, a waiter may not have the freedom to hold on to a talkie while he moves around with trays and dishes.

This function allows voice activation for calls and ensures smooth communication even without touching or holding the radio.

4. Noise Reduction

A restaurant is typically rowdy and noisy. This can impede on smooth communication if not addressed.

With the covert earpiece, audio is not dissipated, but targeted only at the ears, which enhances clarity and reduces distortion from surrounding noise.

Apart from this, it has a Squelch function that runs from levels 0 to 9 and helps to cancel out external noise.

5. 50 CTCSS 208 DCS

Walkie Talkies require protection against interruption. The Retevis RT21 has 16 channels through which it can communicate with other radios.

The Continuous Tone-Coded Squelch System (CTCSS) ensures that this is done effectively and over discreet channels.

It prevents interference by other radio users which can disrupt your communication over two-way channels.

6. Portable Build

Portability is also very important when it comes to two-way radios. No one wants to drag a large radio around the place, because bulkiness can make you very uneasy and uncomfortable.

This walkie talkie can fit into your hands easily and is regarded as one of the most portable radios on the market.

7. Best Usage of Retevis RT21 Walkie Talkie

As an FRS Radio on the UHF band, this Retevis RT21 is suitable for indoor, commercial uses, including restaurants, hotels, malls, museums, factories, warehouses, departmental stores, church, event management, school and other retail or distribution purposes.

We don’t recommend this radio for very long-distance purposes like hiking, kayaking, or mountain climbing due to its limited range.

More so, this two-way, portable walkie talkie is suitable for neighborhood use and for family.

If you need to keep tabs on your kids or your aged parents who need constant care and attention, this can work. Such uses do not require very long-distance radios and this will do pretty well.
