Shimano Di2 intern charger for ST2 S


New Member
Hi all, I bought a used Stromer ST2 S, but seller lost the Shimano Di2 charger. Is there another way to charge the electronic shift unit instead of buying the $130 Shimano internal charger? Seems really expensive for a charger. I just need that wire that connects the control to the USB port.

Any advice would be greatly appreciated thanks!
I misplaced my Di2 charger and think I used an old Blackberry charger for awhile.
