The laptop portability equation: weight, thickness and battery

Weight is the first travel cost

Laptop weight affects every commute, flight and walk between meetings. The difference becomes more important after adding the charger, sleeve and accessories.

Thickness changes bag fit

A small difference in thickness can matter in a tightly packed bag, but it may also accompany changes in cooling, ports and keyboard travel. The specification should describe size, not imply build quality.

Battery energy completes the picture

A light laptop with a smaller battery may still last longer if its hardware is more efficient. Use watt-hours as a capacity comparison, then confirm runtime claims for the applications you use.

• Compare the exact configuration.
• Count the ports you actually need.
• Consider charger weight as part of the travel kit.
