Get one of those USB-C 65W GaN Charger. I have been using this charger for a while. Can get around RM100 in Lazada/Shopee. You need to get a good quality 100W 5A USB-C charging cable as well.

Your laptop must have a USB-C port supporting Power Delivery (PD). If not, you need to get a decoy cable adapter from USB-C to your laptop charging port. This decoy cable will "trick" a 65W charger to deliver 20V to your laptop.

Of course, your phone must support USB-C charging as well.
