It is a design for the travelers and anyone who need a convenient flashlight.The traditional flashlight maybe too large and heavy to them.And they may need carrying some standby batteries with them.My design is human power flashlight,there is an accumulator inside to save electric by people shaking it.And it is a telescopic flashlight.Can help people to save more space and ease the burden.
