How much power the device consumes when it's switched on.
3.width

1.23m

1.23m

The width represents the horizontal dimension of the product. We consider a smaller width better because it assures easy maneuverability.
The power consumption in standby mode, also called energy-saving mode, measures the amount of power the device consumes when shut down but still plugged in.
5.weight

21.3kg

1.72kg

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
6.thickness

33.1mm

57.4mm

We consider a thinner chassis better because it makes the product more compact and portable. Thinness is a feature highlighted by many manufacturers of mobile devices, but it is essential for a wide range of products.
The more power per year a device consumes, the less energy efficient it is, making it more costly over time.
8.shipping weight
