KESSER 42 litres, 12/24/230 V, down to −20 °C, app control review

A 42 litre compressor cool box operating on 12, 24 or 230 V, freezing to −20 °C, with app control and a power cooling mode.

The bottom line The best capacity per euro in this family, on three supply voltages with app control. It publishes nothing at all about battery protection, consumption or noise — four of seven lines empty.

A 42 litre box for a large vehicle.

Three voltages

12, 24 and 230 V. A car, a lorry and a campsite hookup, without a converter. Three of nine boxes here manage it.

The capacity

42 litres, at the lowest price per litre in this family. For a week away with two people, that is the size that works.

The control

App-based temperature setting plus a power cooling mode for bringing a warm box down quickly. The mode is named and its cost in current is not stated.

What is not here

Battery protection. Daily consumption. Noise. Insulation. Four of seven lines. On a box that will run overnight on a leisure battery, the first two are the ones that decide whether it can.

A note on the listing

The bullets are set in decorative mathematical unicode characters. They read normally on screen and are not reliably handled by screen readers, which is worth knowing if that matters to you.

Questions owners ask about this one

Why does 24 V support matter?

Because lorries and some larger vehicles run at 24 V, and a box that accepts only 12 V needs a converter. Three of the nine boxes here accept both; this is one of them.

What is a power cooling mode?

A setting that runs the compressor harder to reach the set point faster, at the cost of more current. Useful when loading a warm box; expensive if left engaged. The listing names it without stating the consumption difference.
