Walkie Talkies for All Situations. The walkie-talkie set is fun for leisure activities of all kinds. In particular, children can learn the basics of communication technology through the simple operation. Creativity and fun are thus guaranteed, and every child will be thrilled with such a gift! With these devices, bike trips become twice as enjoyable, and when camping or at an amusement park, you can stay in constant contact with the X4-TECH walkie-talkies. These handy walkie-talkies are also practical companions in everyday life and work. Additionally, walkie-talkie devices are increasingly being used indoors, for example, by staff in large hotels or care facilities. They always work - free of charge, without mobile fees, and without SIM cards. Furthermore, the devices are extremely robust, making them safe to hand over to children without worry. Radio fun for young and old. The walkie-talkie 2-pack allows for registration-free communication for everyone. To communicate with each other, both devices must be set to the same channel. The devices operate in the PMR frequency range at 446 MHz, where radio channels are available for public use (Personal Mobile Radio). The radios have a transmission power of 0.5 watts, allowing for impressive ranges: in open fields, distances of up to 3 km are easily achievable, and if you are on a hill or by the sea, you can even cover up to 30 km. Power supply is provided by batteries. The walkie-talkie set is powered by four AAA batteries. Eight AAA batteries are included in the package, so you can start using both radios right away. No more annoying searching for an outlet to charge batteries - outdoor enthusiasts especially appreciate this.
