What to Consider When Buying Solar Radios
Solar radios come with so many features. It can get confusing, but here’s what we think are the top three features to look out for.
Whether you want a solar radio for emergency or everyday use, its running time is a very important feature.
Most solar radios have a run time of around four to six hours, while some last up to 10-12 hours.
Choose a solar radio that has an average working time relevant to your needs. For example, if the radio is only for your early morning fishing trips, a shorter working time should be enough. If you’re planning on using it during your overnight camping trips, you probably want one with a longer run time. Of course, the longest run time is always the best for radios that are used during emergencies.
It’s always best to pick the most compact and lightweight solar radio you can get. When you’re out camping or fishing, you don’t want a radio that’s heavier and bigger than most of your gear. An extremely portable radio is also super handy when trying to rush or evacuate in cases of emergencies.
Speaking of portability, consider other features such as carry handles, collapsibility of antennas, hooks, or strings. They make carrying the radio easier and allows you to attach or store them in your clothing, bag, or vehicle.
Waterproofing and Durability
You want to pick a radio that works in any sort of weather condition and built to last. Pick a radio made of rugged or sturdy materials and one that has water-resistant properties. Of course, the most ideal solar radio is one that is not only water-resistant but water and weatherproof.
Check if the radio you want has an IP rating and what it is. The IP rating is essentially a value that denotes how protected your device is from dust and water. Try to choose a solar radio with a rating of at least IP65 as this denotes dust protection and water-resistance.
Solar Radios Frequently Asked Questions
How do solar radios work?
The mechanism of solar-powered radios is really simpler than it sounds. Solar-powered radios are equipped with solar panels, otherwise known as PV or photovoltaic panels. These panels are responsible for absorbing the sun’s energy, or what is more popularly known as solar energy.
The solar energy is then directed to a semiconductor. The semiconductor’s job is to remove atoms from the photons (the sun’s light particles). This process creates an electrical current, which is what is needed by the radio to operate.
What are the benefits of a solar-powered radio?
Perhaps the most essential benefit of a solar radio is that it can be used almost anywhere. Unlike traditional radios, you don’t need to be near a power source to have a functioning radio.
Another benefit of a solar radio comes from the benefits of solar energy itself. There are no electrical bills or having to buy batteries, as all the energy you need comes from the sun. It’s cost-efficient, sustainable, and, most of all, environmentally-friendly as it doesn’t emit harmful emissions.
Lastly, one significant benefit of a solar radio is that it provides everyone with crucial information. Some people reside in isolated areas who otherwise have no access to broadcasting technology nor electricity. This inaccessibility limits information they receive, so solar radios are great for keeping them up-to-date with the world’s current affairs.
Can I get weather updates using a solar radio?
Not all solar radios do, but most of them should be weather update capable. Solar radios are designed for emergency use, so it makes sense that they can provide important weather updates.
Most solar radios already have preset weather alert channels in them, which is handy. If your choice of solar radio doesn’t come with preset channels, that’s still okay. Simply set the frequencies manually, so it matches the frequencies set by the National Weather Service.
Solar radios may not be as sophisticated as our high-end home radios, but they’re definitely great for outdoors and emergencies. Our top pick and a clear winner for the best solar radio is none other than FosPower Hand Crank Solar Radio.
This solar radio is compact, portable, has a reasonably powerful battery, and can run for an impressively long time. It’s also packed with other extra helpful features, which turns this radio into an all-in-one emergency or outdoor device. This FosPower solar radio is definitely a must-have addition to your emergency or outdoor kit.
