Will a metal vacuum mug beat a cooler bar with 300mL Ice?

    I guess the question is also when.

    If you have some food or liquid to store. If you use a low quality cooler bag with 200mL to 300mL Ice pack at what point will a Vacuum seal with no Ice beat the cooler bag?

    I guess at the 10 hour mark or 24 hour mark or at some very long period of time.
