How Walkie-Talkies are Powered.

One of the great inventions has been that of walkie-talkies as they have been making the lives of many easier.

Originally invented at the time of the second world war, separately yet simultaneously by Donald Hings, a Canadian and American inventor Alfred Gross and Motorola. These devices are also known as 2-way radios, although there’s a slight difference between them. Walkie talkies are potable handheld radios that work on shared, single bands and communicate in a wireless system. These are also known as handheld transceivers or HT or handy talkies.

Being wireless and handy, these can be taken anywhere you want. These typically consist of a speaker and a microphone, and an antenna built-in. These handy two-way radios resemble cordless phones or telephone handsets. They are directly held up in front of our mouths to talk. These devices are half-duplex and historically powered by batteries. These are called transceivers because of their ability to receive and transmit radio messages.

A single radio channel can be used by multiple devices to transmit messages. However, only one device can send, and various receivers can listen on the same channel selected. For loudspeakers, unlike modern mobile phones, privacy is not a relatable term for handy 2-way radios. In general, these devices are in receiving mode, and if someone needs to talk, they need to press a button to stop the receiver transmission and convey their message. This system is called a push-to-talk (PTT) system. These are quicker and easier to use for the absence of keypads to dial numbers or even to rely on the freckly signals of cell phones.

These are primarily designed to operate within specific short-distance ranges for communication. The handy two-way radios have several components like batteries that supply power, a microphone, a speaker, an antenna, the PTT button, and some circuitry. For transmission, these radios use electromagnetic waves of frequencies having units mostly kilohertz to megahertz. Sometimes for jamming of several frequency bands or channels, interferences may occur.

Whilst the majority of Walkie Talkies  are retailed with an AC adaptor for traditional charging of the internal battery, they need not be connected to a power source to keep them working. More regularly we are able to source USB or vehicle lighter adaptors for charging on the go. With the drive in technology to sustainable power sourcing, there are more devices emerging to market that enable hand-crank or solar charging of the device batteries.   These help the devices run even in power cuts or in the middle of natural calamities or disasters when the power stations are sabotaged. So, in a literal meaning, these devices do not need the power to work, only batteries.

Whilst we don’t currently (September 2021) have any sustainable power source radios listed, if you are interested in purchasing this alternative technology please do call the office for a tailored quote.


I would just like to say a huge thank you to the walkie talkies team for the delivery of my Pronto radios. I only ordered them at 4pm and they arrived next morning. Great initial communication and the radios exactly as described.

Dear Walkie-Talkies, I just wanted to say a massive thank you for my new charger pack what a fantastic handy piece of kit, it will serve me well on my motorcycle trips and when we go camping. Also may I say what a easy process it is to purchase from your website and the charger arrived next day. If I have any further requirements I will most certainly be coming back to you.

We have been working with Walkie-Talkies to equip our front of house and facilities staff with radio equipment for several years now. I have always found their personnel to be very personable, professional and knowledgeable. They have always strived to tailor solutions to meet our needs and our budget, even allowing us to trial equipment to make sure that it fitted our requirements. Their after care service is also excellent. I would most definitely recommend Walkie-Talkies’ services.

Was looking to upgrade to digital radios for my school and decided upon the Motorola DP1400 and has proved to be an excellent investment. The radios were great value and delivery came early the next day. Will definitely be using you again.
