The emergency tool has a built in hand cranked charging system.
Safety tools are great but they are only good if they are charged when you need them. We all have multiple items to keep charged and everything always seems to need charged.
In an emergency, you can crank up enough power to run your flashlight for over 20 minutes. It will also get you 6 minutes of the flashing warning light.
Maybe most importantly, it can charge your phone in an emergency situation. This truly could be life saving.
