Re: Low-voltage DC is just USB now
If this was a 24W charger, it was already using USB-PD. 5V on USB tops out at 15W. Given this, the laptop should at least be able to charge slowly from that power source. While it wouldn't be able to run and charge because the power is too low, it should be able to charge for use later. If Dell has decided it shouldn't, I entirely understand the irritation.
