I have a Dell Precision 7750, which has a strong GPU, and therefore a power adapter with 240W.
When I'm on the road, I need to charge the laptop with a power bank. My power bank is 65W.
I want to charge the computer, even if it is very slow to charge. I don’t want to run the GPU when doing this, so probably the computer does not consume 240W but much less.
When I plug the power bank via the USB C Thunderbolt 3 connection, nothing happens, and warning comes up that the PC is not charging.
What can I do?
