I am getting a Solio solar charger
to charge my electronic items while on cycling trips.
It will have a female USB socket,
which means that any items that can be charged through USB
can be charged by the solar charger.

So I'm looking for a charger for my Canon Digital IXUS 500 Camera's NB-1LH Li-ion batteries
that plugs into a USB socket and charges the batteries through the USB socket.

Does anyone know if anyone makes such a charger?
Many Thanks.
