Brick to wall cord depends on the country where your wall is located. Also, there's about two standards of power cord connection: trapeze like on desktop PC PSUs and three cylinders merged, so company can outsource power cords to a wholesale OEM. But USB-C will solve your problem. I currently throwed away my laptop brick and just using a GAN power supply with two USB-C ports. It also charges my phone, and, eventually, other stuff like VR headset, joysticks and so on. I have two things micro-USB left: Kindle reader and JBL speaker. I hope next generation of those will be manufactured with USB-C charging ports.
