Crank radio, Dynamo radio or solar radio?

In the event of an emergency, you need to be able to receive important information  from the authorities or weather broadcast. You also need to be able to follow media reporting no matter where you are.  
 
Therefore, a crank radio, dynamo radio or solar driven radio is a good thing to have your emergency box. A crank radio is not dependent on the mains, but you charge the built-in battery through the crank dynamo or through the solar cells on the top of the emergency radio. Usually the emergency radio also has built-in flashlight and USB output so you can also charge your mobile phone.

What Is an emergency Radio?

A hand-crank radio is a portable radio powered by a hand-operated crank. By manually turning the radio's hand crank, mechanical energy is converted into electrical energy, which in turn powers the radio. Often, the crank is combined with rechargeable batteries or solar panels.

Hand-crank radios are often referred to as emergency radios because they are specially designed for use in crisis situations or remote locations. They come in various models and are equipped with features such as built-in flashlights, mobile phone chargers, and AM/FM radio reception.

Purchasing a hand-crank radio is simply an excellent insurance policy for receiving information from the authorities during emergencies, making it an essential item to have in your emergency kit.

 

Why Is an emergency Radio Important in Emergencies?

In a crisis situation, having access to information from authorities is of utmost importance, as they provide updates on dangers, risks, how to respond, and where to seek assistance if needed.

But what if the power goes out, the internet stops working, and phone lines are down? That's where a hand-crank radio, capable of being powered by alternative sources, becomes invaluable.

A hand-crank radio can be a lifesaver during a crisis. It's easy to use, and you don't have to worry about it breaking down if the power fails. A fully charged emergency radio can provide crucial information for many hours, helping you make decisions that can impact your survival and safety.

Ensure Communication During a Crisis with an AM/FM Radio

In Sweden, information about the country's situation is broadcasted through P4. Therefore, having a hand-crank radio is essential if the power goes out and your batteries run out.

In case of important public messages, known as VMAs (public warnings), they interrupt certain private radio channels' broadcasts to reach as many people as possible.

The broadcasting frequency for these channels varies in different parts of the country, with 25 local channels, also called preparedness channels, having a specific responsibility to inform the public during emergencies or major disruptions.

Information is crucial in an emergency! That's why it's a good practice to always set your radio to the relevant frequency after using it.

How much do I need to crank to use the radio?

How much you need to crank to use your hand-crank radio depends on several factors, such as the radio's model, battery capacity, the signal strength of the radio station, and how long you want to listen to the radio.

In general, you may need to crank for a few minutes to get a few minutes of listening time. It's good to keep in mind that just a minute of cranking quickly provides a little over 10 minutes of listening.

Below, we've compiled a table that provides an approximate overview of how long you need to crank to get a certain listening time on a hand-crank radio with a 1000 mAh battery capacity:

Cranking Time – Listening Time

2-3 minutes of cranking gives 10 minutes of listening.

7-8 minutes of cranking gives 30 minutes of listening.

15-20 minutes of cranking gives 1 hour of listening.

45-60 minutes of cranking gives 3 hours of listening.

2-3 hours of cranking gives 6 hours of listening.

4-6 hours of cranking gives 12 hours of listening.

Please note that this is only a rough estimate, and the time it takes to crank can also vary depending on factors such as your physical condition and the speed of your cranking.

Hand-Crank Radio – A Multifunctional Solution

Listening to Radio: You can listen to both AM and FM radio with a hand-crank radio.

Receiving Emergency Broadcasts: Hand-crank radios can receive emergency broadcasts from authorities and organizations.

Charging Your Mobile Device: Some hand-crank radio devices have a USB port that allows you to charge your mobile phone or other electronics.

Using as a Flashlight: Many hand-crank radio devices have built-in LED lights that can be used as flashlights.

Surviving an Emergency: Hand-crank radios don't require an external power source, making them essential tools in emergency situations where power and batteries are unavailable.

A Hand-Crank Radio Is Useful in Many Situations

A hand-crank radio is very practical in survival situations, but there are also other occasions where it can come in handy.

On a Boat

As a boat owner, a hand-crank radio is an excellent addition to your communication equipment. Regardless of the type of boat and existing equipment on board, you can always listen to maritime reports with a hand-crank radio. Moreover, it doesn't take up much space and can be easily stored in a confined area.

At the Summer Cottage

If you spend time in a location with poor mobile coverage, such as a summer cottage, a hand-crank radio can be very helpful. Some hand-crank radio models also come with a mobile charger, so even if the power goes out, you can still charge your phone and communicate with the outside world.

During a Hike in the Mountains

When you find yourself in more adventurous environments, such as a mountain hike, you often can't get reception any other way than with a radio with an antenna. Additionally, you're far from modern conveniences like power outlets.

Charging Methods for Hand-Crank Radios

Hand-Crank Charging

An emergency radio with a hand-crank that is charged by manually cranking it. This is essential for the reliable operation of the radio.

Solar-Powered Hand-Crank Radios

Some hand-crank radios have built-in solar panels to provide power. Solar charging usually serves as supplementary maintenance charging for the battery.

USB-Powered Hand-Crank Radios

Certain hand-crank radio devices can be charged via a USB cable. This means you can charge the radio using a computer or a mobile charger.

AC Adapter-Powered Hand-Crank Radios

An adapter that allows the radio to draw power directly from an electrical outlet. Nowadays, it's more common to use a USB cable to charge the radio.

Battery-Powered Hand-Crank Radios

Most radio devices support regular batteries (AAA or AA).

Important Considerations

Rechargeable batteries discharge over time, even when not in use. Just like a car battery, rechargeable batteries in a hand-crank radio need maintenance charging to prevent them from going into a deep discharge state. If this happens, the battery can be damaged, affecting its performance and, in the worst case, rendering it unable to charge.

Here's what you should do:

When you receive your hand-crank radio, charge it overnight using the included Micro-USB cable.

Then, charge the hand-crank radio as needed but at least once every other month to ensure that your radio's battery remains healthy and operational when you need it.

Batteries are considered consumable items and are not covered by the warranty. Therefore, it's crucial to follow these instructions to maintain its function over time. If handled correctly, the radio's batteries can last for many years and withstand thousands of charges.
