I have a power bank and would like to load my laptop Unfortunately, de Powerbank has only Usb outputs and the cable has only such a socket connection. Is there a possibility?
Not really, from the bank by inverter to 230V and then by power supply back down to DC is conceivable inefficient and quite a detour. Aiming would be what made with a Boost Converter on the normal input voltage of the power supply also outputs, but comes heavily on the bench to see if that really helps.
OK
With this cable, you will probably only be able to load your power bank to later z.Bsp. To be able to use on the campground. I think you need a usb - usb cable for your laptop and also a usb - mini usb for your phone. Everyone should find this at home. The manufacturer assumes this and does not deliver it.
Sorry, I think my answer was not correct, but maybe this video will help you
