[NAME]  There actually are some adapters meant to take a USB PD signal and provide power to a barrel-style connector.  This is one of them.  I've never used one of these, so I can't speak to how well it will work.  One reviewer claims to have successfully used it with a Dell laptop after changing the battery charging from Adaptive to Standard, though.[NAME] Anh  If you want to research those, make sure your USB-C power source provides at least the amount of wattage that your laptop expects, and I would specifically focus on checking for compatibility with Dell laptops, because if Dell laptops can't properly identify the wattage of the power source, they treat it as an unknown adapter and reduce their power consumption as much as possible as a safety precaution, but that causes performance throttling.
Hello everyone,As you know that USB-C PD charger is quite popular these days.I just wonder if it would work for any previous gen of laptop which still use round 4.5x3.0mm one through an adapterIf there is any possibility to do it, please kindly let me know, I appreciate it. 'Cause I want to change my old laptop charger to a GaN one for multi-devices charging
