Do you have a bunch of batteries in that junk drawer in your kitchen? You probably have a pile of battery packs. But are you sure that everything you actually need is there? Look over your whole house, check what you’re really going to need for an emergency, and that you have the battery backup for it.
There’s a rule in the preparedness world:
1 is none and 2 is 1
That means, if you use one, you have nothing left. If you had 2 and use 1, you have 1 left. make sure that you have that backup of your backup battery, especially with anything that you would need during an emergency. That means your emergency lights, your emergency radios, any medical equipment, smoke/carbon monoxide detectors (yes, because house fires still happen in emergency situations), and any other electronic device that you feel you will need.
Back up your backups, folks.
