Is a Portable Power Supply Necessary In a Disaster?

Nowadays, various natural disasters occur all over the world, such as earthquakes, super typhoons, volcanic eruptions, heavy rain, snow disasters and other natural disasters occur frequently. For example, the Turkish earthquake that was sent recently, at 9:17 on February 6, 2023  (4:17 on February 6, local time), a magnitude 7.8 earthquake occurred in Turkey with a focal depth of 20 kilometers and an epicenter at 37.15 degrees north latitude , 36.95 degrees east longitude. At 18:24 on February 6, Beijing time (13:24 on February 6, local time), a magnitude 7.8 earthquake occurred in Turkey, with a focal depth of 20 kilometers and an epicenter at 38.00 degrees north latitude and 37.15 degrees east longitude. The death toll from the earthquake has exceeded 50,000. Turkish President Recep Tayyip Erdogan stated that the damage caused by the earthquake has exceeded 104 billion US dollars.

In addition to earthquakes, the number of floods and landslides caused by typhoons and heavy rains has also increased year by year in recent years. In July 2020, the torrential rains that hit southern Kumamoto Prefecture in Japan caused great damage to the watershed. It may be necessary to reconsider what to do when lifelines such as power, gas, and water are cut off.

In the "What-if" Disaster Preparedness White Paper - Disaster Awareness Survey conducted by Panasonic Japan in 2021, when people were asked what difficulties they had in preparing for power outages due to natural disasters, 19.7%  answered "mobile phone batteries" ;  17%  answered "power generation products", and power supply related products ranked high, which shows that the preparation of batteries is not perfect. The capacity of mobile power is larger than that of mobile phone batteries, so the biggest advantage is that you can have power anytime, anywhere. In addition, when combined with a solar panel, as long as there is sunlight, power can be secured even during long-term power outages, and power saving can be achieved through power storage. Many people originally purchased it to use it at the campsite, but with the increased awareness of family evacuation, the number of households preparing portable power sources has increased year by year.


Scenes in which a portable power supply is used:

Preparation of "power supply" necessary for securing information

Smartphones play a very important role as an information gathering tool in emergency situations. It will be a reassuring ally in information gathering and exchange. Phone batteries are mainly used to charge smartphones and tablets, so many people probably have them. But most mobile phone batteries only have USB output, which cannot be used for computers and lights. The portable power supply not only has a large capacity, but also has the characteristics of high output power and various output terminals. For example, ALLPOWERS S1500 mobile power supply has a capacity of 295200mAh/1092Wh. That's a capacity that can charge about 98 smartphones. In addition to 4 AC outputs, it also has 3 ports for cigarette lighter output and USB output.

Can be used for evacuation at home

When a large-scale disaster occurs in which lifelines are cut off, it is normal to go to an evacuation center, but in reality, it is difficult to accommodate all residents in a densely populated metropolis. With more and more local governments calling for "evacuation at home", large residential complexes are less likely to collapse. The needs of each household for disaster countermeasures equivalent to "self-help" are increasing year by year. You may be wondering if your home is an environment where you can evacuate at home. In fact, it seems that there are many cases where people who evacuated at home went to the evacuation center to charge their smartphones. So, what do you need to prepare for sheltering at home? Specifically, we need three things: preserved food and water, energy sources such as electricity, and toilets. Storing electricity is the hardest. Portable power supplies that can store large amounts of electricity can be used for this purpose. The portable power supply has many types of terminals and high output power, and it can be used with all electrical appliances in case of power failure. In addition, since there is less self-discharge, it can be charged and stored as a backup power source. In addition, if a solar panel is prepared, it can be charged by sunlight, and the power supply can be ensured even if there is a long-term power outage, which is more secure.

How to get the most out of your portable power supply


A portable power supply purchased for emergencies. I think there are some people who keep it in the closet. If you try to use it in an emergency, you will inadvertently run out of battery. In order to keep the portable power supply in a good state of charge, it is important not to leave it for a long time and to get used to using it on a regular basis. For example, how about using it as a power supply for a barbecue in the garden, or going outdoors with your family and friends once a month with a portable power supply? In addition to checking the battery status, you can also experience how long a product can be used. Please try to prepare while incorporating it into your daily life. For storage, if you are not using a portable power source to charge your device, we recommend turning it off. A dry and well-ventilated area is also important.
