Naturehike Camping Cooler Box - 24L

Naturehike does not publish an hours figure for this particular model and we are not going to invent one. In practice a pre-chilled 24 litre box packed properly will hold ice through a hot day and into the next morning. Ask us and we will tell you what customers report.

Pre-chill the box overnight, fill it as full as you can, and use block ice rather than cubes. Air is what warms a cooler, so a full box holds far longer than a half-empty one, and every opening costs you.

Roughly a third of the volume as ice for a hot Tanzanian day. Frozen water bottles do two jobs at once: they chill, and you drink them as they melt.

Not straight away. Cold melt water keeps things cold better than the air that would replace it. Drain it when it stops being cold or when the food is sitting in it.

Out of direct sun and off a hot floor if you can, and never in a closed boot in the sun with the lid facing up. Shade is worth more than insulation.

Wash it out with warm water and bicarbonate of soda after every trip, dry it fully, and store it with the lid ajar. A cooler closed damp in Dar humidity will smell within a week.

No. Dry ice is far colder than the plastic is rated for and can crack the liner, and a sealed box with dry ice in it is a pressure risk.

These are insulated, not heated. They will hold hot food warm for a while but they are designed to hold cold.
