Hopefully you can read my review but short answer is "YES" if you shut down your 2018 MBP and just charge up and run of the battery. I wouldn't try extending battery life once charged by using BOTH at same time, especially if you have a dedicated Radeon 450, 460, 555, or 560/560x. That GPU can kick in an use 35W on avg BY ITSELF, Add that to the 45W TDP of your 15" MBP CPU and it becomes exact same situation with 20,000mah PD juice packs like ANKER, they can deliver 22W-45W but that is more like enough to charge up an internal battery while shut down and THEN run the machine off the internal battery in a pinch. Trying to do simultaneously might even generate an error. But yeah, in a pinch, shut down a 2016-2018 MBP and you can USE this USB C charger safely just like a 22W PD juice pack and at least get another battery charge and just use entirely off battery in a pinch.
