The recent blackout that left Portugal and Spain without electricity for several hours has shown how we are dependent on mobile and internet to access information and news. But when the battery is over and the signal disappears, how can we continue to follow what’s going on?
The answer may be one of the oldest and most reliable equipment of any house: the radio to batteries. Simple, autonomous and effective, it remains one of the safest means to receive updated information during prolonged energy failures.
Why does radio still be an essential tool?
According to Civil Protection recommendations of the European Union, portable radio should be part of any emergency kit.
In serious failure scenarios on the power grid or communications, radio stations remain active, ensuring real-time updates.
According to Economistthe European Union expressly includes stack radios or crank in the recommended equipment lists for 72 hours of family autonomy in emergencies.
What kind of radio should you look for?
The ideal is to opt for a portable radio that works for AA or AAA batteries, easy to find and store. There are also hybrid models, which include USB charging, solar panel or even crank for manual energy production.
According to the same source, the most complete emergency models combine several power sources, ensuring greater durability in unpredictable situations.
We recommend:
FM: The most reliable channel
It is essential to ensure that the device captures FM emissions, the range where most general, public and private stations are tuned. Some radios also operate in AM (middle wave), useful in more isolated areas.
Write the Economist That, in some countries, public emergency alerts are issued in FM. In Portugal, antenna 1 is traditionally the following channel for official updates in real time.
Models with flashlight and USB port
Some radios include LED flashlights, sound alarms and USB ports to charge mobile phones in case of need. The load capacity is limited, but sufficient for a call or urgent message shipping.
According to the same source, this functionality is common on compact emergency radios, often available in sports stores or online platforms.
How to ensure that radio is operational?
Like other emergency equipment, radio should be tested periodically. Check signal reception and replace the batteries annually, even if they have not been used to avoid escapes or damage.
According to the batteries should be stored outside the device and in a dry place, away from heat and moisture, to conserve their load.
Where to keep and when to use?
The radio must be accessible, in a central cabinet or included in your emergency kit. Ideally, it should be next to flashlights, candles, lighters, medicines, bottled water and non -perishable foods.
Even out of extreme contexts, radio can be useful during storms, localized energy failures or whenever digital networks fail.
A simple solution for uncertain times
In an increasingly digital world, portable radio continues to ensure a direct connection with the outside, even at times when the network or electricity disappears, as in a blackout. And for less than 20 euros, it is an investment that can be worth more than it seems.
