If the the keyword you are targeting is the product itself (i.e, Asus Zenfon 5 A502C2G), the product page might be easier to rank especially in very niche industries.
What you can do is:
1. Optimize the product descriptions for your target keywords
2. Interlink of possible for proper crawling.
3. Create a unique product description for each product. One common problem with product pages is that it creates duplicates.
4. Observe Amazon product pages if you want to learn more.
