Hi Bose_Luddite,
Thanks for the question!
The Soundbar 700 uses an industry standard C7 power cable. You should be able to find this cable on Amazon by searching "C7 power cable".
Let us know if you have any questions!

Hi there,
Welcome to the community!
You could use the same C7 power cable, or look for a similar cable with one squared off side.
Best,
Brandon
