Whether you're building a new home, renovating your house, or simply want to fireproof your home, we're here to help....
If you lose power during an emergency, staying in the know is a priority. This is where a hand crank radio comes in.
But what exactly is a hand crank radio? How does it work and why do you need it?
If these questions live in your mind rent-free, we got your back. This post explains how a hand crank radio works and why you need one.
What Is a Hand Crank Radio?
A hand crank radio is a crucial part of any emergency scenario. But before we discuss what a hand crank radio is, let’s see what a hand crank means.
A hand crank refers to an arm (or lever) with a rotating shaft. The arm can be attached to the shaft or be a bent extension of the shaft. When you turn the arm, the shaft reciprocates the circular motion.
As the term implies, a hand crank powers the radio. Turning the hand crank for two minutes usually powers the radio for up to an hour.
Many hand crank radios include other power sources. Some have batteries, while others can be charged or solar-powered. These radios also have additional features, such as flashlights and LCD screens.
Since these devices don’t rely on power, they can provide you with potentially life-saving emergency information. They’re also extremely helpful during emergencies like house fires and blizzards.
Additionally, most hand-crank radios are NOAA (National Oceanic Atmospheric Association) weather radios. They can receive emergency and weather updates from the association’s 24-hour radio station.
So, if an emergency occurs (e.g., you’re affected by tornado season), you’ll be updated with the current situation. This lets you know what to expect and how to prepare for it.
How Does a Hand Crank Radio Work?
The radio generates power by turning the hand crank. As you turn the crank, it heats up and produces power for the radio.
In particular, the crank generates power with the help of a conductive coil wire and a magnet.
The coil wraps the magnet. As you turn the hand crank, the coil around the magnet rotates. This produces the power the radio needs.
In addition, a regulator exists to ensure you don’t generate too much power and burn the circuits.
Hand crank radios have helped many people through fires, hurricanes, and storms. They’ve also helped those in places without electricity and areas to charge.
Plus, hand crank radios have saved many lives, keeping people safe from danger during emergencies.
Why Do You Need a Hand Crank Radio?
Here’s why you need a hand crank radio in your emergency kit:
1. Hand crank radios give you weather updates.
Hand crank radios are usually weather radios that can receive weather updates from NOAA’s 24-hour station.
You can receive severe weather and emergency alerts in real time. During a crisis, instant alerts make a lot of difference.
However, you must choose weather alert radios, not weather band radios. Weather band radios must be tuned in to a local station to work, while weather alert radios update you regardless of the station you’re tuned in to.
2. Hand crank radios are reliable.

During big disasters, hand crank radios are usually more reliable than phones. Disasters such as earthquakes, hurricanes, and volcano eruptions can disrupt cell towers.
When disaster strikes and the power goes out, hand crank radios are the best option for staying updated. Plus, many hand crank radios have multiple sources of power, including solar batteries and rechargeable ones.
In addition, hand crank radios come with flashlights, clocks, and LCD screens that come in handy during emergencies.
3. Hand crank radios are durable.

Hand crank radios can last for years. They’re also waterproof and shock-resistant.
So, you don’t have to worry about getting another one for the next several years.
