The most important safety measure that can be taken is to ensure that you are able to communicate during extreme weather.
Emergency response systems have self-contained back-up power good for about 72 hours leaving time to contact the monitoring center for assistance. If you have phone service through your cable company and the power fails the response system fails with it.
Many seniors have cell phones today. They are not dependent upon an immediate power supply if they are kept fully charged. However, it does not take much for the battery to run down.
During the last power outage I was able to maintain 3 cell phones fully charged with a battery pack I purchased from Sam’s Club for $59.
Whatever power supply you choose should have a USB port to charge things like cell phones and laptops. If the power supply is always plugged in it should be ready for use during the next power outage. I was without power for 7 days and the battery pack had more than ample power for 3 cell phones and two computers. Peace of
mind for only $59.
