It means that it eats around 1 Kwh per hour.

The best desktop power is around 500 W.

Answer 3

the ac unit

Answer 10

The best way to conserve energy and use laptop economically is to use the Laptop on Battery Mode, shift to A/C connection when the battery is very low.

As you use with A/C connection, the battery also charges up. Again you can repeat when the battery is fully charged.

(But, the more often you use your battery, the faster the internal resistance of the battery increases.) Don't worry about this as it will effect once in 3 or 4 years, by the time, the technology would had developed for other options.

Answer 11

laptop behaves as a single load but in Desktop, there are separate monitor, CPU & sound system which independently act as loads. So,obviously Desktop uses more energy.

Answer 12

In my opinion, aircond unit consumes more energy. Yet, less using aircond and don't let laptop unit on all night. A lightning may spoil your laptop.

Answer 13

AC
