Everyone should have a flashlight in their emergency kit, survival bag, or car, just in case. But there’s one problem with keeping traditional flashlights stored for an emergency — they operate on batteries. Over time, even without frequent use, those batteries run down, potentially leaving you without a working flashlight. If you want a flashlight you can depend on in any situation — no replaceable batteries required — you need a hand crank flashlight. A hand crank flashlight doesn’t need typical batteries to work. Instead, you power it up by turning a crank. They’re ideal for emergencies or survival situations or any environment where you’re without power sources. Check out some of the best hand crank flashlights below.
