How useful is the 220V AC socket in the Prado 150?

220V AC socket in the Prado 150 - how useful is it? It's a 220V AC socket that is rated for 100W.. and it seems like its not particularly useful. Supply obviously comes from the vehicles single battery, and it only gets power when the vehicle is running.

Is there a 12V DC socket in my Prado?

Most gear like tire air compressors or camping fridges run on 12V in any rate, yet there is no 12V DC socket in the back of this Prado that I can find. Also a 12V socket would have been better as I suppose their are less losses than converting the 12V to 220V.

Can a nl90 run off a Prado's 100W socket?

I run a NL90 off the Prado's 100W socket when traveling. No problem. Low voltage reticulation we use (12V) is not always as good as its cut out to be. Low voltage means high current, high current means thicker wire for same losses or just higher losses with heat generation. Also hotter joints if it not a good one.

How much power does a 240V inverter take?

The power supply for the fridge when running on 240V would only be about 75% efficient therefore it would be taking about 3.75A form the inverter. The inverter is again proberly about 75% efficient so the inverter would be pulling around 4.7A from the battery when it's running. Not very efficent!
