Best way to cool cans bottles with no power

[Long john]

Hi
Would like to keep some cans cool for up to 12 hours
Would an ice box filled with ice last? Do the thermo boards last longer then ice cubes?

Thanks

ice packs will last longer than ice cubes

Best just to try it and find out.

If you have an insulated box like a picnic hamper then put as much ice init as you can and then your bottles.
Leave the melted water in the box and it will keep at temp for hours.

In the weather we have just had maybe not 12 but it will keep to temp for hours.
