What type of charger for Lenovo Yoga 720 13ikb?

It was looking like the type C charger being used for phones in pictures but I thought it might be different or I read that's just an option? *What charger comes in the box?* I'm thinking of buying a used one that doesn't come with a charger.
Providing an amazon link to the charger would be most helpful

Here is an amazon link for UK

and for the US

Search [google works fine] using the exact model number. Vendors will tell you which charger to get. I check two or three to make sure they're the same voltage output

You must buy a special laptop charger specifically compatible with that model. Phone chargers with a USB C will not work. The links David posted are good.
