How long do these stay frozen for ?

Mine have stayed frozen for approximately 9-10 hrs. I left food in the cooler,which was well-insulated, and it which was still cold when I got home. This was kept in office setting with temps in room in the 70’s.

When you say that this item is colder than ice, what does that mean? ice can be cooled to any temperature unless i'm mistaken. a rock can be 18*f.

Karæthon's answer is correct. Freezing or melting overcomes the "latent heat of fusion" which is about the same heat as is required to raise the temperature of (for example) liquid water by almost 80°F, or frozen water (ice) by about 150°F. So an ice pack in a cooler will spend most of its time at it's melting point. Once it's all melted, the subsequent temperature rise will be very quick.

They are reusable. There is an initial "just add water" setup to change the dry powder to gel, then you throw them in the freezer for several hours and they are ready for use.

If I were to use two of these together, would I have similar cooling capacity as one of the medium-sized packs?

Not positive of that but I am amazed at how well these things work. 4 of them keeps a large cooler super cold.
