Hi, I'm getting ready to travel the Western Coast of the United States and I'm trying to find if it exists a device that can provide charge to my HP ProBook laptop. Short of simply buying two extra laptop batteries and charging them, is there any device that can adapt from 12V to a laptop WHILE it is currently on and being used? I was thinking just a massive power bank but the issue is that a laptop is not charged via USB it is charged via its power cord connection. So, is there any way to find a 12V male to laptop-adaptable cable or is that connection to an HP ProBook simply proprietary?

My goal is basically to try and achieve continuously renewable and sustainable power efficiency without having to leave my vehicle.

Thanks for Info!

This is the one I used to use with my old laptop. It works well and did the job.

How are you travelling? do you have access to a 12V cigarette socket in a car? You could get a cigarette socket to an inverter and then just use the power brick for the laptop.

Other than that consider that a laptop battery will be in the 10's of thousands of mWh, so maybe 40,000 mWh. The bigger Li-ion battery packs are perhaps 20,000 (at a lower voltage), so you'll get about 1/3rd out of it, so you'll be carrying something that weighs at least 6x a 20,000 battery pack per charge.

Travelling via car. So, I don't have my 12V adapter where the cigarette lighter should be (GRRRR!) because I made the mistake of letting CarToys turn that into a capped USB port. Little did I know that once that is done it is very difficult to revert it back. What I did get is one of those mobile car jumpers (1300A) that has a cable that will convert to female 12V so if I do have something that uses the 12V to draw power I can use that. I did also research into getting an inverter in my car but I was told that there is a danger to the car battery and to the alternator and that if not careful this can actually kill your car so that scared me away from that idea pretty quickly.

How did you find a cable that adapted this to your laptop charging port? Did it come with it? What kind of laptop do you have?

Thanks!

Mine came with a short cable and a couple switchable plugs. My previous laptop was a Clevo p650 or something like that (I sold it a month ago so can't check the model number). I of course could not use the powerbank and game on it at the same time since that laptop was way too powerhungry for that but for notetaking in class and working on the train it was more than good enough.

No worries, there's no such thing as a gaming laptop anyway but I would like to use my laptop for web browsing (I have an unlimited Gigabit data plan built into my laptop) and movie watching in the evenings while I'm travelling. Thanks for the tip! I'll have to try and see if this will adapt to an HP ProBook.
