Cooler Shock Cooler Shock Ice Packs for Cooler - 3 Reusable, Long Lasting, Cold Freezer Packs for Coolers, Lunch Bags & Totes to Keep Food Fresh - Clear

Non-Hazardous, 5 lbs. when filled, replaces 7 lbs. of ice. They stay at 18° Degrees F. for hours on end using a phase change process. Our packs release the largest amount of energy at freezer temperatures to get your food and beverages cold quickly. Put them in the freezer for 24-48 hours (depending on if it’s completely warm) and you will have portable cooling power that accelerates cooling. CoolerShock is shipped to you with a dry formula inside. Simply add water and put the screw cap on. The pack turns to gel in 15 minutes. It lasts all day (24 hours) in size-matched coolers. Great for fishing, boating, parties, and tailgating. Add room temperature drinks to your cooler and drink them at near-freezing temperatures a few hours later. Drinks should not be left in direct contact with ice packs for a prolonged period as they can freeze.
