Here's The Honest Truth About The Retevis RT637 Walkie Talkies

Retevis RT637 is one of several portable walkie talkies for kids from the Retevis Kids brand. This can also be seen directly from the 6 different, colorful designs in the colors purple, red, green, orange, pink and blue. You can find out whether the radio can meet the requirements for a walkie-talkie for children in the following test report.

Measurements and Weight

As part of my test, I measured the Retevis RT637. According to my measurements, the dimensions are about 15.3 x 5.5 x 2.7 cm at the widest points. This makes the device very comfortable in children's hands. The weight, on the other hand, is 68 g without batteries. Even with batteries, the RT637 weighs just over 100 grams. This means that even children can easily hold it for a long time.

Battery Life

The Retevis RT637 is powered by 4 AAA batteries. These can be exchanged at will. This means that the walkie-talkie can be used for as long as you like with enough batteries. If the batteries are not changed, a charge lasts about a day with intensive use. If the radio is only used occasionally, the batteries can easily last a week.

Private Communication  

The Retevis RT637 uses PMR446 for communication. 16 channels are available for this in the frequency range from 446.00625 MHz to 446.19375 MHz. Furthermore, encryption with 38 CTCSS and 61 DCS codes is possible. This allows conversations to be conducted quite privately. The channels are changed using the buttons on the device. The current channel is shown on the display. This allows even children to compare whether they have set up the same channel.

Full Features  

The number of functions on the Retevis RT637 is quite manageable. Like almost all walkie-talkies, this device also has a VOX function. This enables communication without having to hold the radio in your hand all the time. There is a flashlight on top. This means that children can also use the RT637 in the dark. A key lock prevents the channel from being accidentally changed during use. If this does happen, a channel scan will help find active radio operators nearby and tune to the correct channel. Last but not least, the adjustable volume should be mentioned. This allows you to adjust the volume of the call to your own needs.

Conclusion 

Anyone looking for a simple walkie-talkie for children is well advised with the Retevis RT637. The radio is available in attractive colors, is easy to use and fits comfortably in the hand. There are also helpful functions such as a flashlight or the VOX function. The range of 1.2 km is also perfectly sufficient for most children's activities.
