The TZS First Austria 40L Electric Cool Box with Wheels sits at number five in this guide at £99.95, with a 4.3 rating from 233 Amazon ratings. It is a thermoelectric box rather than a compressor fridge: the listing says it cools to 18°C below the ambient temperature and warms up to 50°C, and it comes with both a 12V car lead and a 230V mains lead. It also has wheels, a telescopic handle, cable storage in the lid and an internal divider.

This product is the clearest example of the problem this guide is about. The name calls it a 40L box, while the capacity bullet and the specification field both say 45 litres — a five-litre gap on a box that is listed as holding 65 cans or 15 wine bottles. The listing never says which figure is usable space and which is the outside of the box, or whether one of them is simply wrong. Two smaller details are worth reading twice: the specification lists a moulded 2-pin BS 4573 shaver plug rather than the usual three-pin plug, and the 18°C cooling figure is a drop below whatever the room is, so on a 30°C day the box is working towards around 12°C rather than fridge temperature. Everything on this page comes from the Amazon listing itself; we have not tested this cool box.

## Questions people ask

**Is the TZS First Austria cool box 40 litres or 45 litres?**

The product name says 40L, while the capacity bullet and the specification field both say 45 litres. The listing does not explain the difference or say which of the two figures is usable space.

**How many cans does the TZS First Austria 40L cool box hold?**

The listing says the 45L volume fits up to 65 cans of 330ml, or 15 wine bottles of 750ml lying down.

**Can the TZS cool box run from a car?**

Yes. The listing includes both a 12V car cigarette lighter connection and a 230V mains connection.

**Does the TZS First Austria box keep things warm as well as cold?**

The listing says it cools to 18°C below the ambient temperature and has a warming function up to 50°C. It is a thermoelectric unit, not a compressor fridge.

**What plug does the TZS cool box use on mains?**

The specification lists a moulded 2-pin BS 4573 shaver plug. That is the two-pin shaver format rather than the usual three-pin plug, so it is worth checking your socket before buying.

The listing says it has rugged wheels and a telescopic handle for transport without heavy lifting, plus built-in cable storage in the lid and an internal divider.
