When I was a kid my family owned a device whose sole purpose was to rewind vhs tapes.

    I have an old 6 volt lantern that uses a battery that is 6 inches wide, 4 inches tall, and 3 inches deep.

    If I turn it on it gives you almost enough light to actually see where you are going and the battery lasts for about 2 hours.

    With two 18650s I could replace that battery for a package 2/3 the size of a pack of cigarettes and run that light for a day or so.

    If I replace the bulb in it with an LED equivalent I could probably stretch that out to nearly a week.
