Charging problem with Evoo EG-LP6-BK 17" Laptop

Evoo EG-LP6-BK 17" Laptop FHD i7-9750H 2.6GHz NVIDIA GeForce RTX 2060 6GB 16GB. I have bought this item and realized that I was provided a wrong charger which is not as recommended in laptop's manual for 180 watts rather provided 120 watts. Could any please provide info for a right charger or any buying options?
