I have not yet tested how long it can feed my laptop which normally is externally powered from the mains via an AC Adapter.

While visiting a DIY-store I saw this nice and affordable torch. I did not hesitate and bought it immediately, because recharging it is so simple: wind for 10 seconds and you have light for 10 minutes [and 30 seconds will give you 30 minutes light]. It has white LEDS which give a blueish white light; one of these days I might make a red cap.

This HP AC/DC Adapter: Mains to 18Volt DC feeds my LX200 very well !
