Petromax Cooler Backpack 27 Liters – for unpowered cooling, organization, and on-the-go provisions
When long outdoor tours are planned, cooling quickly becomes a challenge. That's exactly what the Petromax Cooler Backpack with 27 liters volume was developed for. It combines the cooling performance of an insulated cooler box with the mobility of a backpack – ideal for hikes, hunting trips, boat tours or camping.
The cooler backpack works completely without electricity or battery. Thanks to strong insulation and a waterproof zipper, ice cubes or ice packs remain reliably inside and keep food and drinks cool for extended periods.
Thanks to padded shoulder straps, the backpack is comfortable to carry, even when fully loaded. At the same time, several external pockets offer additional storage space for small equipment or cooking utensils.
Why this product?
Unpowered cooling only works properly when packing logic, access, and insulation are aligned. Accessories help keep things organized and prevent unnecessary loss of cooling performance.
- better organization in cooler box or bag
- quick access without leaving it open for long
- more practical for vehicle, camp, and hunting grounds
Practical Tip: Packing a cooler correctly
Pre-cool, put heavy items at the bottom, frequently used products at the top. The less time the box stays open, the longer the cold will last.

Our Assessment (Practical Added Value)
The biggest advantage of a cooler backpack compared to classic cooler boxes is its mobility. While cooler boxes often have to be transported, the cooler backpack can be comfortably carried on the back – especially practical for hikes or longer walks to the campsite.
The large volume of 27 liters offers sufficient space for food, drinks, and ice. Especially on multi-day outdoor trips, it can transport a complete meal.
Many outdoor cooks also use the cooler backpack as a mobile supply station: fresh meat, vegetables, or drinks stay cool, while the rest of the backpack remains free for equipment.
Tips from Outdoor Practice
Pre-cool cooler backpack before the tour
If the interior is cooled before packing, the cooling time is significantly extended.
Use ice blocks instead of ice cubes
Large pieces of ice melt slower and ensure more stable cooling.
Pack backpack as full as possible
A well-filled cooler backpack maintains the temperature more stably than a half-empty one.
Avoid direct sunlight
The cooler backpack should ideally be in the shade to maximize cooling performance.
