I had a bad run with phone chargers/cables in 2020. 3 had connector issues and there was a voltage issue with 2 more. So now I test them in the store if possible, if not then as soon as I get home. Best to be sure, especially if you count on it for an emergency.Picked up a battery pack for my flip phone I can keep in my pack in case the power goes out, or if I'm out in the woods for extended time. also a charger to keep in the truck that charges off the lighter receptical.
