Not sure how long this has been available but it just stumbled upon it recently. Little usb magnetic battery charger that will work on a multitude of different rechargeable batteries. While it may not be useful if you need to charge several batteries for a headlamp or multiple flashlights at one time, it’ll come in handy in a pinch. For barely over $10 shipped I may order a couple more and toss one in my work backpack and the kids cars.
