just got home with my 09 Sienna XLE and have a question. I see the two 115v outlets - can these be used for anything? can i plug my laptop in there and run it continuously while the car is running? i realize when parked it will drain the battery but i'm looking for some guidelines as to what i can use and how long - both while the car is off and when the engine is running.
thanks so much!

I'm sure the power output is limited, but it can probably charge a laptop. I don't think those draw too much power.
 
Check in the owner's manual for the limit on amps.

thanks - appreciate the input - just wondering what people use these for. we're doing a long (1 mo) cross country trip and i'm planning ahead! perhaps a george forman grill!

Those may pull moe power, and if so you may end up blowing a fuse.
 
It's probably meant for things like laptops, portable DVD players, and Nintendo DS/PSP portable gaming systems.

Your 115 VAC power probably comes from a CHEAP(***) MSW (Modified Sine Wave) 150-200 Watt inverter. Not compatible with MANY AC devices/components. Consult your owners manual before plugging anything into that supply.
 
*** Relative to doing it correctly, PSW, Pure Sine Wave, inverter.

my owner's manual says do not use appliances that require a combined total of more than 100W. if more than 100 W is used, the protection circuit will cut the power supply.
 
my laptop uses 90 W (per the fine print on the power adapter). I use my laptop all the time. What I don't know is the following:
is the limit of 100 W total for the sienna between the two outlets and therefore I only have 10 W that can be used in the other outlet or is it 100 W per outlet so if I had another laptop I could run it in the other outlet at the same time.
 
the manual seems to imply it is total for both outlets combined but does not say so explicitly

100 watts equals roughly 10-12 amps from your 12 volt system and manufacturers often choose a 15 amp limit for this sort of option, cigarette lighter, etc.

Does that mean I can use only one laptop (90Watts) per van
 
or one laptop per outlet => two laptops per van (180 Watts) assuming we've only got two AC outlets

My bet would be that provided the laptop battery is already fully charged the typical current draw, wattage use, of your laptop would be in the range of 30-50 watts. 90 watts is probably the maximum rating of the laptop's 115 VAC power supply and only rises to that level with the laptop componentry powered and charging a fully discharged laptop battery.
