We will gladly forward Sujushi's answer to you:
It's enough for charging. (Suggested on the Razer website)

But keep in mind!
If you connect a second usb-c device to the power supply, the performance will be reduced.

I would also recommend that you don't play games when charging the laptop, as the performance may not be sufficient and the GPU and/or CPU may slow down.

For on the go or just charging during normal use yes


Hope I could help
