A:AnswerHello Farjana,
As long as the rice cooker requires less than 120W AC, then yes it would work. Simply make sure that the total WATT of all the devices you try to plug into this power strip add up to UNDER 120W.
A:AnswerIt depends on the laptop's power consumption. My Dell laptop has a 90 watt adapter, so I am confident this 120 watt inverter will power the adapter.
