The 13-inch MacBook Pro and 14-inch MacBook Pro with 8-Core M1 Pro processors come with 61W and 67W power adapters, respectively, meaning a USB-C monitor with 60W or 65W power delivery should be able to keep them charged while using them.
However, 60W isn't enough to charge the 10-core 14-inch MacBook Pro and 16-inch MacBook Pro.
