PSU compatabiliy for USB-C powered compatability

A very basic question. I have a Razer 13 laptop with original psu. It outputs at ....5v 3A and 9v 3A and 15v 3A and 20v. 5A

I have another psu by a different manufacturer that is much lighter which I was hoping to take travelling.

It wont charge the laptop though. I have a cable for it that is capable of carrying 100w. This second charger can supply up to 120w. But it outputs (according to the info printed on it) at 5v 3A. 15w.....9v. 3A. 2.7 W...11v. 6A max. 66w. max ...20v. 6a max. 120w maximum

So this second unit doesnt output at 15v unlike the otiginal one .

I am wondering if this is why the second psu wont power the laptop. and if i should give up trying!
