Razer Blade 15 Basic 2020 -- can I charge the battery with USB-C??

Hello All, This is my first post on Razer's forums. I'm thinking of buying a 2020 Razer Blade 15 Basic. I can see its battery is mainly intended to be charged with the proprietary connector from the wall adapter. No problem. My issue is I already own several USB-C chargers for my previous HP laptops. Most are 90W or so. The specs for the Blade 15 mention it has a Thunderbolt3 port (USB-C). In most laptops, having a Thunderbolt3 port means you are able to charge the battery using a USB-C charger. However, from what I've read, the presence of a Thunderbolt3 port is not a guarantee that you can charge a laptop's battery via Thunderbolt3. I've looked through the specs for the Blade 15 Basic. Other than mentioning the presence of the Thunderbolt3 port, there's no info to clearly say whether it can be used to charge the battery. Does anyone know the answer?? Thanks, Patrick
