LED light shines usefully for a good while after
a battery charge.
This is accomplished via a fold-out dynamo winding
handle. Also, and certainly more convenient, it
will accept 6Vdc from a commonly available power
supply unit. It comes without such a PSU but they
are pretty ubiquitous.
Nothing more to say, it's pretty useful.
