10 Best Solar Powered Radios in 2021 (Review)
Under a natural disaster situation, it is highly probable that communication networks will be restricted or may not be active. A radio is always a gadget that you will want to include in your survival kit for an emergency signal or alert.
A battery-based radio is not suitable for this type of condition because as soon as the radio runs out of power, you won’t be able to charge it until you find replaceable batteries. Under natural disaster situations, it is highly improbable that this happens.
Therefore, the best solution for staying safe is to choose one of the best solar powered radios in 2021. Powered by solar energy and by hand cranking mechanisms, you will never run out of power with these radios. Take a look at this short and interesting guide on solar powered radios to find out what the top models are in 2021.

The Best Solar Powered Radios
1. Kaito KA500 Emergency AM/FM/SW Solar Powered Radio
The Kaito Voyager KA500 emergency AM/FM SW solar panel radio is the perfect tool — not only for contingency situations such as climate disasters or power outages, but also for outdoor activities.
The solar radio uses three AA batteries (not included) that can get charged through different methods. The radio acts as an alert system that has an integrated high-quality AC brushless generator that allows it to recharge using a hand crank methodology (spinning a small lever to generate electricity).
Moreover, the radio features an AC/DC adapter port that also allows it to get fully charged rapidly by using an AC power outlet as a source; a useful tool to have before starting a journey. Finally, the Sun, as the inexhaustible source of energy on our planet, also serves as a power source thanks to the integrated solar cell. The solar panel’s tilt angle can be adjusted with a 180-degree angle range to fit the optimum tilt angle and maximize performance. This way, with all these power sources, the alert radio never runs out of power.

How to Choose a Solar Powered Radio – 3 Features to Look For
Available Power Sources
The solar powered radio needs to have multiple power sources available to ensure durability and long performance under extreme situations. The most common methods in these types of devices are hand cranking, solar panels, and USB connections. It is important to notice that those products which can tilt the angle of the panel will always be preferable over the ones that have a flat solar cell installed.
More than that, some products will allow you to select two types of batteries. Either lithium-ion or AAA tech batteries. This feature is very useful. If you run out of power in one of them, you will be able to instantly use the other battery without having to recharge it via solar or through a dynamo.
The working time is the next factor to consider. A solar powered radio is intended to last as many hours as possible on a single charge. Some will provide between 4-6 hours while others may be able to provide up to 8 hours of work with the radio. You must be careful not to confuse the working hours for the integrated flashlights with the working hours for the radio itself.
Finally, additional features can also make a difference. Remember that these radios are intended for both emergency situations and outdoor sports or activities. Therefore, they should be easily combined with solar rucksacks through a carabiner or attachment device.
Other features such as a compass, dog whistles, SOS red lights, headphone jack ports, and an IP rating protection can also make a difference. Always remember that as a valuable camping tool, you can also combine it with other devices such as camping solar panels that will make your off-grid experience much more pleasant.
How Do Solar Hand Crank Radios Work?
Solar hand crank radios work by utilizing one of two mechanisms: solar energy conversion and a dynamo.
One of them is based on solar energy conversion, working just like any other solar-based device (e.g. solar watches) by placing the integrated panel under the sunlight, it generates DC electricity that is later used to charge the lithium or NiMh battery.
The second mechanism is based on a dynamo. A dynamo is an electrical machine that generates DC electricity when its rotor spins thanks to a mechanical force. This dynamo is integrated into the structure of the radio.
A hand crank radio will have a small lever that is connected to the rotor of the dynamo. While spinning the small lever, you are also spinning the rotor which, at the same time, creates an electrical current in the output of the dynamo that is used to power the integrated batteries. To better understand the working principle of a dynamo, you can watch this video.
How to get Weather Updates Using a Solar Radio?
The best way to get weather updates in a solar radio is to stay tuned with the National Weather Service, which sends messages under the following frequencies:
- 162.400 MHz
- 162.425 MHz
- 162.450 MHz
- 162.475 MHz
- 162.500 MHz
- 162.525 MHz
- 162.550 MHz
Solar weather radios already have pre-set channels for these radio frequencies in many cases, and if not, you can simply tune the radio to those frequencies to stay updated.
