I take photos and videos and have a lot of adapters and cables on my desk so I needed a compact one Solution. trick on my 13" macbook pro. i plug in 2 ssds, an sd card, charge my laptop and connect an external monitor through this thing and it keeps all the performance while my macbook is charging, and keeps the connection between everything seamless.I think it's because it runs on a 15V 2.3A output.It loses charge on my 15" Macbook Pro when I have everything plugged in. The maximum output is 20V at 1.75A, so when all my devices are plugged in it gets kind of warm (though not hot) and it loses some power, maybe 2%-5% per hour, which is perfectly acceptable , if you have a few p hours working on a medium sized project in an SSD and SD card that will keep battery level of existing Macbook Pro 15 and maybe charge it by 1%-2% every hour. I'd say if you're planning on using the full setup with a MacBook, this works great with anything under a Macbook Pro 15" 2018.
