In recent years a number of battery-less radios and flashlights (and some combination units) have come on the market. These devices use a hand-cranked dynamo or small solar panel to charge an internal battery. Typically two to three minutes of cranking will give you five minutes or so of light or 10 minutes of radio.
While they have the advantage of not needing batteries, think about whether you can or want to continuously crank them to keep the light or radio going. You may be better off having a regular flashlight and radio, plus a large package of standard alkaline batteries.
Whatever you choose, get the items and get them now. They will fly off the shelf if the need arises for them.
