Seems pointless in taking 12v DC and inverting it up to 230v AC, then reducing it back down to 19v DC.

 

 

I'm not an electronics expert but surely that is actually easier than increasing 12Vdc to 19Vdc directly without converting to AC on the way.

 

Is there a way?

I can but cite my own experiences, that on the boat I plug my Laptop (19v) into the boat 12v system and it works - it don't get much simpler than that.

It will be anything but simple inside that plastic case. 

 

Unless there have been developments since I was at college, there is probably an oscillator in there to change the 12v to AC, a transformer to step it up to 19Vac, and a rectifier to switch it back to DC.

There lies madness !!!

Hence my last sentence!!

 

However, it isnt pointless, and nor is it madness, if it is the only option at the time.

 

As far as i know, the electricity that reaches our homes enjoys a variety of voltages on its journey. Your logic would suggest that is also pointless and madness, whereas, in reality, it is merely a means to an end.
