When things go wrong, you don't want to fall into the dark. Don't know if the storm will get worse or not sure if the rescue will come before the situation worsens. This is not a good feeling.
Hand crank radio as an emergency radio will help you stay connected to the latest news and updates, even if the internet doesn't work or there is no electricity. Receiving key information that can save lives in an emergency can be your last line.
The most basic purpose of emergency radio is to provide a functional means to receive AM and FM transmissions in the event of a power outage or isolation from civilization. Emergency radio typically uses minimal or renewable energy sources such as batteries or solar energy.
In this article, we will offer a list of 5 best emergency radios to help you make your choice.
Suitable for all types of emergencies and natural disasters, the Kaito KA500 emergency radio is equipped with high-quality AC brushless generators and solar panels to power the unit and charge the internal battery.

The United States often experiences hurricanes. Once the hurricane has been confirmed, you will realize that the connection may become a matter of life and death. However, for many of us, the concept of buying an emergency radio is comparable to buying a typewriter. Is it really necessary to rely on this old technology in an emergency?
The short answer is yes. This old technology is still the best choice to keep abreast of the situation in an emergency.
The hand crank radio is a portable receiver that allows you to be permanently informed about news or environmental conditions in an emergency. Forgive me for taking the time to explain.
The radio wave travel distance is much farther than any LTE transmission, which makes it easier to receive signals and the radio transmission reaches more people, which is the biggest priority when making emergency transmissions. In addition, this concept makes more sense if we consider how radio waves work. Basically, radio waves have two important factors to consider, frequency and range.
The higher the frequency of a radio wave, the more information it can transmit, but the smaller its range. This works in the same way in another way, the lower the frequency, the less information to transmit, but the farther the wave propagates.
Traditional hand crank radio waves operate at low frequencies, typically between 525 and 1705 kHz, and in the case of AM, 88 to 108 MHz (1 MHz = 1000 kHz) for FM radio. This means that the range of AM stations is much larger than that of FM stations. The latter has a higher frequency and is often more local.
Whether it is 2G, 3G or LTE, cellular technology operates at 700 to 2100 MHz in the current network. This means that cell towers are great for transferring large data volumes, such as your Netflix stream, videos you upload to YouTube or Instagram photos, but the same speed means it's much lower. This is why a city has a larger number of cell phone towers to provide the same coverage as radio stations.
On the other hand, the number of transmitting antennas required to transmit emergency information to most parts of the country is a few hundred times greater than the number of transmitting antennas required to transmit information only to major urban centers. Therefore, the radio is the best choice because it is the choice to deliver the same information to more people with the fewest resources.
On the other hand, in the most recent emergency, both technologies have a certain amount of bandwidth, and in the case of cellular technology, millions of people are trying to communicate at the same time, especially in such an emergency. Can cause congestion and service disruption. For the radio, as a passive system, there is no personal monopoly bandwidth, so you can always rely on the emergency radio to get new useful information that can save your life in a real emergency.
When the terrible hurricane season is coming, you must be vigilant and prepared to keep you and everyone safe. When a storm occurs, security agencies always recommend taking all predictions and carrying a range of potentially useful items. Emergency radio or hand crank radio is one of the items you need in your emergency package, it will keep you informed, and then we will present the best 5 hand crank radio and emergency radios.
