    I remember reading how a 12v dc converter can blow the fuse or ruin the 12v battery, is there a safe way to have a 110v outlet installed that runs off the main battery so I could for example plugin my laptop? You'd think an electric car would have an option for an outlet :)

    Off the main battery? Surely you jest. I think a low-wattage12v DC -> 120v AC inverter wouldn't hurt the battery if you unplugged it when not in use. What are you trying to power? Edit - I meant what's the wattage of the laptop?

    Isn't this incredibly inefficient? If you plug a laptop into this, the power brick converts the 120V AC back to low voltage (probably 5V) DC.

    I'm not an EE, but seems like you lose power in converting to AC and then back to DC for a DC appliance.

    I blew the fuze in my 85d. It's a serious shortcoming in an electric car. My last two hybrids had 120v outlets and we used them for the phones and laptops with no problems.

    Agree that this is pretty standard on today's cars. Our other car has a 110V outlet and it is handy when needed.

    you can get adapter that plugs into the 12v outlet and goes directly to the laptop - just do search 'laptop car adapter' on amazon to see examples...

    Does seem silly to go from 12v dc up to 110v ac then back down to 19v dc (most laptops)

    Yes, not ideal, but I wasn't using it for a laptop. Is there a better way to add a 110V outlet?
