UPDATE: MARCH 12, 2024: My great gang just invited me way up north to a fishing camp. No electricity. Beautiful sky, stars, air, nature, bears, trout. No way rechargeables would work. So glad I will switch to the Lumity battery model so I can continue to love the outdoors, on or off the grid.
Please consider carefully before getting rechargeables. If you never travel, spend lots of time at home and are unlikely to have any emergency that takes you out of your living space, rechargeables are the way to go. If you put in long days, travel often, are frequently called away from your home base, batteries are the way to go. You do not want to get stuck late at night in an Emergency Room after a long day, when your recharging station is at home and you MUST understand medical instructions for yourself or others.
