How long does Techni Ice last?
It depends on how often you open and close your cooler, how many sheets you use, how cold you froze the Techni Ice (recommended time of freezing is 24 to 36 hours before using. The longer you freeze, the colder your freezer, the quality of your cooler, the longer it will last). A typical camping cooler with Techni Ice should give you 1 to 4 days approximately of lasting coolness, a day cooler will last a day, and a lunch box will last through a normal lunch period.
