Document Type and Number:
WIPO Patent Application WO/2008/034363
Kind Code:
A1
Abstract:
A charger for a portable electronic product having a charging circuit includes a
motorial mechanical-energy collecting device (1) that is mounted on the main body
of the portable electronic product and is used to collect and store a part of the
motorial mechanical-energy from a carrier for the portable electronic product,
a mechanical-energy to electrical-energy converter (2) that is coupled with
the motorial mechanical-energy collecting device and converts the mechanical-energy stored
in the motorial mechanical-energy collecting device into electrical-energy, a
current processing circuit (3) that is connected between the output of the mechanical-energy to
electrical-energy converter and the input of the charging circuit for the portable
