Many fakes are being produced, of both wind-up and Faraday (shaken)
torches. Have read about the wind-ups, can't remember the details, but
the 'magnet' in some Faraday torches is actually a lump of iron and the
'storage capacitor' is a battery. So you think you're charging a big cap,
but in fact the LED is running off a (probably not very good) battery and
a small mediocre cap. I know, I got suckered
