Mini-USB to USB-A lead (Kendal LA9)

I've recently been using a brilliant (quite old) teeny speaker, and it'll need charging soon, but I realise I don't have any leads that fit it! It takes a Mini-USB lead (the kind that would fit the socket in the photo). Does anyone have such a lead they no longer need, please, ideally with a "normal" USB-A on the other end (the type that fits into a mains plug head to stick in the wall socket)? Thank you very much if so!
