Introduction
The typical walkie-talkie looks like a telephone handset with an antenna put on top, a speaker built into one end, and a microphone built into the other (with some devices the speaker also doubles as the microphone). To speak, they are raised to the face. A half-duplex communication device is a walkie-talkie. Two-way radios are high-end, feature-rich radios intended for commercial users, such as companies with big sites, hospitals, security, event management, and other scenarios where a quality device is necessary, according to the majority of professional users.

Frequently Asked Questions
That depends on the power level you have it set for. The radio can be set to 2 watts, or 5 watts, or 8 watts. When set to 8 watts the typical, line of sight, range will be about 5 miles. With lower power setting or obstructions between radios the range will decrease accordingly. Being a ham radio operator I can contact a ham repeater that is on a hill top about 10 miles away. So the actual answer is “the range varies under varying conditions.
We only used the docks for charging.
You have to be in same channel.
No programming. Simply select and match pre-programmed channels to numerous units to communicate
i would imagine if you were in the out of doors and needed to communicate. i just got the one to listen to emergencies. no power sever stuff happening. still haven’t been able to pick anything up thou
There is no separate battery pack. Rechargeable batteries are sealed within the walkie talkie unit itself. To recharge the unit it is placed on a charging stand which is powered by standard 117 v AC. There is no USB connection/connector.
I’m not aware of one oh, but that doesn’t mean they don’t exist keep searching
Yes they can work without the antenna, but the signal decreases significantly if no antenna is installed.
Hi there, the charging docks are designed to be compatible with the power source of 110-230V input.
Yes! They worked great for the 6 of us, on the ship, even in the elevators, but not in the medical center. We had to change channels a few times. They also worked in the towns in Alaska, when we were on excursions.
Yes, a half mile would not be a problem for these radios.
You can use any two units in any location as long as you are within radio range of the other unit
It comes with the antennas pictured and the ear piece is just like what you can buy at walmart with a mic on it. I am highly satisfied with this purchase. I would recommend them they are good quality at a low price.
No, these have their own battery pack and they come with a charging station.
I bought 4 and only used them together. They worked GREAT tho!!! Way cheaper than upgrading 4 cell phones with international plans.
Hi there, it depends on which model you are referring to. Greaval GV-8S walkie talkies use the 2-pin earpiece jack, an earpiece with 2-pin plug would be compatible with Greaval walkie talkies.
Hi there, yes they can get charged once you put them on the charging base and connect the base to your power supply, you will see the LED indicator on the base show a red light during the charging progress and it will turn green when charging is complete.
