FAQ
What materials are these cool boxes made from?+
The exterior is typically constructed from durable polyethylene plastic, known for its resistance to scratches and UV damage. The insulation often utilises expanded polystyrene (EPS) foam, which provides excellent thermal retention. Internal liners are usually a food-safe PVC.
How many ice packs would I need to fill a 26L cooler?+
For best results, especially in warmer weather, you’ll likely want around 3-5 standard-sized gel ice packs. The exact number depends on the ambient temperature and how frequently you open the cooler.
Are these cool boxes suitable for long trips?+
While capable of maintaining coolness for shorter trips (1-2 days), extended use may require more ice packs or supplemental cooling. Consider using block ice rather than crushed ice for longer durations to minimise melting.
How easy are these cool boxes to clean?+
The polyethylene exterior is easily wiped down with a damp cloth and mild soap. The internal liners are typically removable and dishwasher safe (check manufacturer's instructions). Regular cleaning prevents the build-up of bacteria.
Can these cool boxes be used in direct sunlight?+
Prolonged exposure to direct sunlight will significantly reduce their cooling efficiency. Ideally, position them in shaded areas or use a reflective cover to minimise heat absorption.
What is the warranty on these cool boxes?+
Amazon offers a standard 30-day satisfaction guarantee. If you’re not completely happy with your purchase, you can return it for a full refund – subject to Amazon’s terms and conditions.
Are these cool boxes suitable for transporting frozen food?+
While they can hold frozen items for a short period (a few hours), prolonged freezing is not recommended. The insulation isn't designed for maintaining consistently low temperatures for extended durations.
Do the seals on these cool boxes leak easily?+
High-quality models will have robust, airtight seals. However, it’s important to inspect them regularly and ensure they are properly aligned when closing the lid. Minimal leakage is normal with ice packs.
Are these cool boxes suitable for use in a car?+
Yes, these cool boxes are generally suitable for car transport. However, be mindful of space constraints and ensure they don’t block your view or interfere with driving safety.
What is the maximum weight capacity of these cool boxes?+
Each cooler is designed to hold up to 26 litres of contents. However, avoid overloading them as this can compromise their structural integrity and insulation performance.
