Comparison – Retevis RT21 vs RT27
Since it already has the same frequency programmed, Retevis RT21 can be used directly, making it the best choice for anyone looking for an easy-to-use walkie talkie. Just switch the power button on, and press the PTT button to turn the transmitter on and the receiver off. It only has a few buttons for much more convenient usage. Additionally, it comes with soft buttons that are easy to adjust.
On the other hand, Retevis RT27 has a different and more complicated setup, unlike the previous model. To turn it on and adjust the volume, the power button must be switched clockwise. The channel knob must be rotated clockwise to switch between channels to change the channel up and counterclockwise to reduce the channel down. Press the PTT button to transmit a call, and then release it to receive a call.
RT21 is not waterproof, but it is water-resistant. There is no need to worry if it gets splashed with water as it comes with a compact shell. This feature also makes it drop and heat-resistant. Similarly, RT27 is not a waterproof device; however, its product details suggest that it is not water-resistant, unlike the previous model.
Both devices can keep up with light splashes of water, but they may malfunction once exposed to water for a long period of time. Although the devices do not have a waterproof feature, both have a protective sealed design, making them very durable.
When choosing a walkie talkie, considering its battery life is a must. You have to ensure that you can use it for a long period of time without recharging the batteries from time to time. Both RT21 and RT27 run on 1,100mAh Lithium-ion (Li-ion) batteries, which are said to last about 10-12 hours depending on their usage. Both batteries are rechargeable, and it takes around four hours to charge, but only Retevis RT21 offers a quick charging feature. Additionally, Retevis RT27 also has a USB charging feature for more convenience.
There is no need to compare both devices’ power sources since they use the same battery type. Both models can last long when they’re not used a lot, and it’s also a perfect choice for activities that require much longer use of walkie-talkies.
The Retevis RT21 can reach its range between 0.5 to 2.5 miles, depending on various conditions and obstructions. It has a power output of 2.5 watts. You can achieve an extended range if you use the device in an open field with no barriers. However, its range is restricted and reduced when used in the city, where there are many buildings and other interferences.
With Retevis RT27, it can only reach a range of 0.5 to 1 miles with 2 watts output. Just like the previous model, its range is dependent on obstructions. It works best in an open field, but it has a restricted range when used in the city due to interference.
The frequency band of RT21 is Ultra High Frequency with 400 to 480MHz and contains 16 channels to prevent call interruptions. On the other hand, RT27 has a frequency range of 462 to 467MHz with 22 channels available. Additionally, Retevis RT21 is highly operational over American FRS channels, and it is compatible with other radio models if set to the same frequency.
Both devices use an FRS channel, which makes it license-free, but it is stated that a license is required when the FRS channels of RT21 will not be used. If you want to purchase RT27, the device must be exposed to Local Government Regulations. If classified, you may need to acquire a local government license.
A walkie talkie with outstanding features is a must. We look for these features to ensure that there will be clear communication once the device is used and ensure that we are getting our money’s worth without compromising its quality.
