Maximum Wattage of Power Points??
I have an HP laptop with the i720 processor. Because of this, it comes with a 120 watt power supply.
I recently flew a SQ A380 flight, biz class from SIN to MEL. When I plugged in, the power dropped off, as though tripping a circuit breaker. This same phenomenon occurred when tested on several other seats.
Coming back, I rode a SQ 747, top cabin. The same thing occurred.
What is the max allowed power draw on these power points? I want to buy a smaller power supply, just under the limit.
TIA
