External battery charger

Hello,
My Instinct as of yesterday decided it won't charge with the wall battery charger plugged into the wall.  I know it's not the battery because my wife has an instinct also, and i switched the batteries and they charge fine in her phone.  So I have been looking for a Samsung M800 external battery charger.  I see this one: http://www.atomicmall.com/view.php?id=684363

It is for the right model phone and the right model battery, but I am missing the USB to Samsung cable that came with the phone.  Is the USB to Instinct cable necessary or can I use the home cable for this?  It doesnt really describe how it gets charged since it doesnt show a cable in the picture.  Sorry if this is a stupid question, but I figure I should get this answered before I order something I don't need.

thanks

thank you for your time answering this, but I am totally lost on that answer compared to the question that I asked.

Thanks

thanks for the help.  i ordered one.  Dont know why my cellphone can't read the charge anymore, but glad this will solve the problem
