In detail: Indel B TB41 Black, 40-litre compressor cooler
The Indel B TB41 is a portable 40-litre compressor cooler made by Italian manufacturer Indel B, a brand with more than 50 years of experience in mobile cooling for motorhomes, 4x4s and boating. Positioned as the big sister of the TB18 in the range, it targets more intensive use with more people, with a genuine storage compartment rather than just raw volume.
The SECOP BD1.4F Micro FSD compressor, of automotive-grade design, offers two speeds: an economical ECO mode for stable cold retention, and a MAX mode for a fast temperature drop when loading in produce at room temperature. The temperature range, continuously adjustable from +12°C to -22°C, allows use as either a fridge or a small backup freezer. A metal basket with a removable divider is included to help organise storage between drinks and fresh produce.
At 12.6 kg empty (excluding packaging) and outer dimensions of 585 x 350 x 445 mm (700 mm including handles), it remains carryable between two people but is really built for use inside a vehicle rather than being carried on foot over any distance. Power supply is exclusively 12V or 24V DC, with three built-in battery protection levels to prevent the vehicle's battery from being fully drained.
For anyone after a larger-capacity compressor cooler than entry-level models, with a genuine storage compartment and Indel B's well-known mechanical reliability, the TB41 remains a solid choice for intensive use in a van, 4x4 or boat.

Comparison
In the 35 to 45-litre compressor cooler segment, the Indel B TB41 is naturally compared with the Engel MT45F, the Japanese reference of similar size, in searches such as "Indel B TB41 vs Engel MT45F". Here's how the two compare, based on both manufacturers' public specifications.
| Criterion | Indel B TB41 | Engel MT45F |
|---|---|---|
| Capacity | 40 L | 40 L |
| Weight | 12.6 kg | 24 kg |
| Storage | Basket with removable divider | No dedicated compartment |
| Power supply | 12V / 24V DC | 12V / 24V DC and 230V AC |
| Price observed | ≈€483 | ≈€1054 |
In short, the Indel B TB41 stands out for its markedly lighter weight and organised storage basket at a more accessible price, while the Engel MT45F keeps the edge with 230V mains power and a digital display that's been standard on it for longer. Both target intensive use in a van, 4x4 or boat.
Our tester's verdict: Gilles Caron
I took it along for a week-long road trip for two in a converted van, wedged behind the front seats thanks to its handy side handles for carrying it between two people. With 40 usable litres and a metal basket with a removable divider, it lets you actually organise storage (drinks on one side, fresh produce on the other), unlike small top-opening models with no compartment at all. MAX mode brings the temperature down noticeably faster than ECO on first fill, a real advantage for quickly chilling groceries picked up warm in the middle of the day. Once the target temperature is reached, ECO mode holds a stable cold with very reasonable draw on the van's auxiliary battery. My only gripe: at 12.6 kg empty, it's still carryable but noticeably bulkier than the TB18, not really built to be carried on foot over any distance. For intensive use in a van or 4x4, backed by Indel B's well-known mechanical reliability, it more than delivers.
Frequently asked questions: Indel B TB41 Black, 40-litre compressor cooler
ECO mode prioritises lower power draw for stable cold retention once the target temperature is reached, while MAX mode speeds up the compressor for a faster temperature drop when loading in produce at room temperature.
No, this model runs exclusively on 12V or 24V DC. A TB41A version exists with a 230V adapter not included as standard, available separately if needed.
Yes, the metal basket with removable divider lets you separate, for example, drinks from fresh produce, a real advantage over compressor coolers of this size with no built-in compartment.
The TB41 offers more than double the capacity of the TB18 (40 L versus 18 L), with a dedicated storage basket, but it also weighs more (12.6 kg versus 8.6 kg) and targets more intensive use for several people rather than light solo nomadic use.
