VOX hands-free When your hands are not free, there is no need to press the PTT button. The Vox function allows you to better communicate with your companions. Powerful penetration Even in forests or mountains with many obstacles, the communication signal is still strong and maintains clear and continuous call quality. Long battery life With 2000mAh high-capacity lithium-ion battery, the long-term standby power saving mode greatly effectively saves power, and the standby time is longer. Each radio has a charging base with a USB plug so that you can charge it in the car when you are traveling by car. Understanding Walkie Talkie Range: UHF radio waves are weakened and can be blocked by obstacles. Obstacles such as trees will lower radio range while obstacles such as mountains can be expected to completely block transmission. So even though forested areas do attenuate the signal, in these regions you should expect your range to be limited far more by the hills blocking your signal than the trees absorbing it. In more urban areas, buildings will significantly block your signal. Most concrete, brick or metal structures reflect all radio waves. In cities, with a 2 Watt radio, you can expect a range of less than 1 mile.
