Duplicate content: I am selling USB hubs, many hubs have the same ports as other hubs, do I need to write a new description for each product page?

Basically what the title says. I have a H2 for the most important ports of each hub on each corresponding product page, is that bad? For example, many hubs have a HDMI port. Do I need to write a different description for each page?

Also, is it harmful to use the same keyphrase "usb hub" on all usb hub product pages? Yoast SEO plugin seems to think so.
