Petromax Cooler 50 Liters – for powerless cooling, organization, and supplies on the go
When multiple days are planned outdoors – whether camping, on a boat, or fishing – reliable cooling quickly becomes a decisive factor. The Petromax Cooler was developed precisely for this. It keeps food and drinks cool for up to 12 days and works completely without electricity.
The so-called ultra-passive cooling system uses only ice or ice packs. The double-walled construction with cavity-insulated housing stores cold particularly efficiently and keeps the interior stably cool for many days.
With its large interior volume, the cooler offers ample space for drinks, barbecue food, or fresh groceries. At the same time, it is built so robustly that it can easily be used as a seat or a stable storage surface in the camp.
Why this product?
Powerless cooling only works properly if packing logic, access, and insulation are harmonized. Accessories help maintain order and prevent unnecessary loss of cooling performance.
- better organization in the cooler or bag
- quick access without leaving it open for long
- more practical for vehicles, camps, and hunting grounds
Practical Tip: Packing your cooler correctly
Pre-chill, heavy items at the bottom, frequently used products at the top. The less time the box stays open, the longer the cold lasts.

Our assessment (practical added value)
Passive coolers are primarily used where power supply is absent or not reliably available. Especially when camping, on boat trips, or hunting excursions, this system offers a great advantage: cooling works independently of technology.
The combination of thick insulation and large ice volume ensures that food stays fresh for several days. Especially for longer outdoor trips, such a cooler can serve as a central supply station.
Many users simultaneously use the cooler as a seat or stable work surface when cooking in camp – a practical additional benefit that is quickly appreciated in everyday outdoor life.
Tips from outdoor practice
Pre-cool the cooler before the trip
If the cooler is already filled with cold drinks or pre-chilled ice, the cooling time will be significantly extended.
Use large blocks of ice
Large pieces of ice melt significantly slower than small ice cubes and ensure more stable temperatures.
Open the box as rarely as possible
Every opening allows warm air into the cooler. Frequent opening reduces cooling performance.
Choose a shady spot
Direct sunlight increases the temperature of the box. A shady location significantly extends the cooling time.
