Where to find official USB cable for OLED 1000 Vita?

Hi there, I have searched this sub and couldn't find a recent answer so thought I would reach out to the community for help. I recently bought the official Vita portable charger, but I don't have the official USB cable to charge it. Any ideas where I can find an official USB cable for the OLED 1000 Vita? I currently have a generic wall adapter and USB cable.

I have tried eBay, Amazon, and play-asia, but they are either too expensive, knockoffs, or not available for sale any more. I'm in the U.S. if it makes a difference.

I appreciate any feedback. Thank you!
