Must have adapter to power them - no usb adapter from goal zero for sherpa. - Goal Zero Light-a-Life 350 LED Light

I was so excited about these lights and multiple trips I had planned to use them for. Unfortunately, I have no way to connect them to my Sherpa and Nomad 200 that are set and ready to go. USB adapters are lost in the world (hope it's a supply issue not out of production) Either Goal zero needs to change the 6mm plug for other adapters or have accessories available to use that work. I see the lighter plug adapter and an Anderson but for backpacking and remote use, these are not options. Almost $300.00 worth of lights I can't even turn on. The one goal zero USB adapter I found on an ebay store did not even work when it came in (figures)
