Insulation thickness and lid discipline, not the litre figure · review
The longest cooling figure published in this hub at 40 hours, and the listing itself says the number rests on the four ice packs built into its lid.
The bottom line The biggest number in the hub, honestly attributed to the four ice packs in its lid. What it will not describe is the seal those ice packs are cooling through.
A rigid passive cool box stated at 22 litres, measuring 27.5 × 44.5 × 38.3 cm, in food-safe BPA-free PU/PP, with four 450 ml ice packs built into the lid and a stated 40 hours cold or 18 hours warm.
40 hours is the highest cooling figure published anywhere in this hub. The listing does something the rest do not: it says what the figure rests on — the four integrated ice packs, frozen and fitted in the lid.
That is not the same as stating conditions. There is still no fill ratio and no ambient temperature. But an attributed claim beats an unattributed one, and this is the only one here that names its cold source.
The practical point is space. Cooling from above, with the packs out of the load area, leaves 22 litres for food rather than 22 litres minus the ice. It also means the cooling stops when the packs thaw, which is what a passive box is.
No insulation thickness. No gasket or catch on the lid. No drain. No empty weight.
The 40 hours assumes four fully frozen 450 ml packs. Freezing that mass properly takes longer than a night in a full domestic freezer, and the listing does not say how long.

It is what the maker states, tied to the four supplied 450 ml ice packs and to nothing else. There is no fill ratio and no ambient temperature behind it, which is true of every figure in this hub. A number that names its cooling source is slightly better documented than most here, and it is still not a measurement you can repeat.
The same ice packs are stated to work in the other direction, and the same conditions are missing. The point worth taking from the pair is that the lid does the work in both cases, which is why the lid seal — undescribed on this listing — matters more than the figures do.
Soft folding basket · 38 × 24 × 25 cm open · heat-sealed lining · zip closure · 30 kg stated load · no litre figure published
A folding insulated shopping basket with an aluminium frame and a stated 30 kg load, and the only listing in this hub that publishes no capacity in litres at all.
Best for: Carrying a full shop from car to table, where the frame and the handles do more work than the cooling does.
≈ 20 €
Soft folding bag · 30 litres in the title, lunch bag in the bullets · over 12 h stated · isothermal lining, unnamed · no closure described
A folding cool bag whose title says 30 litres and whose bullets describe an office lunch bag five times over — the two halves of the listing do not agree, and this page reports both.
Best for: A packed lunch rather than a picnic, on the reading of this listing that its own bullets support.
≈ 25 €
Soft folding bag · 33 litres stated · about 45 × 25 × 29 cm · 14 h cooling stated · shoulder strap · no insulation named
The largest stated capacity in this hub at 33 litres, with a 14 hour cooling figure and no word anywhere about what the insulation is made of.
Best for: A family picnic where volume and a shoulder strap matter more than the construction behind the cooling figure.
