Your mobile phone is turned off because its battery power became fully exhausted.
In this place you are, there're no one and nothing to get help from.
(Like as a power supply unit, a personal computer, a vehicle.)
How can you do for this situation ???

The answer is 'VOJO dynamo'

In emergency case, If you spend only small effort to trundle it few times,
You can make your mobile phone being turned on a moment.
You can take a short time to call someone or check some telephone numbers or check a map.
And you can use it as a flash light in the darkness.
