Charging Samsung Chromebook from USB socket
 

We make occasional 500 mile car trips, and have a USB charger that plugs
into the car cigarette lighter, which is great for charging phones. What
I cannot find is a lead or adaptor to charge a Samsung Chromebook from
the USB socket. The Chromebook has a tiny circular socket for charging,
rather like earlier mobiles, but smaller.

Cannot find anything suitable via eBay, Amazon or Google, but am
probably asking the wrong question. Any bright ideas, or is there a
good reason why such a device would not work? I can find a charger that
plugs into a cigarette lighter, but that really just duplicates the
charger we already have.

I suspect the answer is that the voltage required by the Chromebook is
higher than that supplied by USB?

I've just answered my own question. The output from the mains charger
is 12v, and USB provides 5v, which presumably explains why the
Chromebook requires a dedicated car charger. Bugger.

Yes USB is 5V, don't know about chromebooks specifically, but many
laptops are 19V give or take a volt

More than likely, You'll have to settle for cigarette lighter-laptop
charger instead of some cigarette lighter-USB-laptop arrangement, it
would take ages to charge even if you could find one.

Eventually USB3.1 will provide sufficient power, it remains to be seen
if laptops will come along that can be charged that way.

Quite possibly have you not measured what comes out of the charger for the
mains to see what it is and how much current charging and operating on that
supply uses?

Just look for a car charger for your specific Chromebook. Something like this?

Alternatively do what I did a long time ago and just get a small 100W or so inverter for running the multitude of chargers that seem to need plugging in. Just be sure it can't be powered when the engine isn't running or you're sure of a dead battery very quickly (they don't like being used for anything other than a short burst of high current for starting the car).

I've got an inverter that plugs into the cigar lighter, and has a 13A
socket on the end. 140W continuous. It was to enable me to charge a
laptop on a hire boat that didn't have its own inverter but did have a
cigar lighter. A bit like this:

I found a 'universal' laptop power supply that runs direct off the car
battery. Works with the three assorted laptops I've tried it with. Cost
about 20 quid.

I also installed a motorbike power outlet on the car - smaller than a fag
lighter one and the plug also clicks in place so doesn't vibrate or
whatever loose. I positively hate cables training from a car fag lighter -
they always seem to get in the way of something. I positioned the
motorbike one in a sensible place for a power outlet.

Yes, for simplicity, I think that is the answer. I was just trying to
avoid carrying two different chargers, but using the one I already have
is not going to be practical.
