Possible to charge USB with maintainer

Justjeffy

I have a vehicle maintainer 10 from goal zero and want to know if it's possible to use it to charge a USB device. The only plugs that came with it are related to connecting to a vehicle.

Not seeing that they sold an adapter that goes to usb. I tried to look for male 6mm to usb and I cannot find one.
