The recent blackout that left much of Portugal without electricity for several hours alerted the need for emergency preparation. One of the main problems faced in these situations is the loss of access to communications due to the unloaded battery of the mobile phone.
According to the Economistone of the most effective solutions for keeping the operational phone during a power failure is the use of a PowerBank.
This small energy storage device can make all the difference in situations where access to the power grid is not guaranteed.
How does PowerBank work?
According to the same source, PowerBank is basically a portable battery that allows you to charge mobile devices anywhere.
The operation is simple: PowerBank is previously carried through domestic electricity and, if necessary, the energy stored to feed the mobile phone is used.
Write the site that there are several models on the market, with different load capacities. The ability of a PowerBank is measured in milliamperes-hour (MAH) and defines how many times you can load the device without the need to recharge your own PowerBank.
What ability to choose?
According to the same source, the choice of PowerBank must take into account the type of use desired. For emergencies such as prolonged blackouts, a device with a capacity of over 10,000 mAh is recommended, allowing you to charge a modern mobile phone at least twice.

Tips for using PowerBank during a blackout
Explains the site that, to maximize the efficiency of PowerBank during a blackout, it is essential to completely load the device whenever possible.
During use, you should avoid completely unloading the phone battery before using PowerBank, as very unloaded batteries can affect charging performance.
Another recommendation is to keep the phone in power savings mode to consume as little battery as possible. According to the same source, turn off non-essential functions such as Bluetooth, Wi-Fi and GPS, it helps prolong the autonomy.
How to keep PowerBank in good condition
To ensure that PowerBank is always ready for emergencies, it refers to the same source that it is advisable to recharge it every three months, even if it has not been used. This practice prevents internal battery deterioration and ensures that the load capacity remains close to the ideal.
Additionally, it is recommended to store PowerBank in a dry place, far from heat sources or excessive moisture to prevent damage to the device structure.
