I have got 3 different USB cables at home, they all fit for PRS-650. One of them is the original one

.
I think I have been using all of them for the last 6 months but now my reader has the problem with battery drainage and I need to make sure I am using the right one. Could you tell me what the cable for prs-650 looks like ?
Is is the one about 1m long with e166307 awm 20376 ... SHIUNG on it.
Is there Sony logo on it ?
Thanks a lot
