Charging my laptop in a car

[Sairaight]

Hi,

I would like to know if it is possible to charge my laptop  HP 15-cx0017nc in a car and how - I assume, there are two options:

1) via USB-C

2) via adapter plugged into car's charging port

My first question - is it possible to charge my laptop via USB-C?

Secondly, I am interested in info regarding what specifications should an appropriate product have, before I buy it - i.e. plug shape/voltage/current... 

Thank you, any help much appreciated

The specs of your machine is

1. Charge using USB-C port: No, you can't. The USB-C port on your machine does NOT support Power Delivery.
2. Using adapter: yes, your machine requires 135 W AC power adapter therefore you need an adapter 12V DC to 135W out for it. Actually I was using the following adapter for many my weekend trips when I was on call support to charge my notebook and batteries for my video and still cameras

Hi,

thank you for your reply. I have additional question -

1) Why does my laptop not support Power Delivery, when it is written in specifications:
"1 USB 3.1 Type-C™ Gen 1 (Data Transfer up to 5 Gb/s, Power Delivery, DisplayPort™ 1.2, HP Sleep and Charge); 2 USB 3.1 Gen 1 (1 HP Sleep and Charge); 1 HDMI 1.4; 1 RJ-45; 1 headphone/microphone combo"

2) Is there some option for charging, where I would plug mu PC in a car cigarette lighter?

Thank you

Sorry my reading. That means you can charge your machine using USB-C port BUT finding a product for charging from your car using USB-C is a question mark. Please let members know when you have found one. Many thanks. Does it come with USB-C charger or normal 135W charger ?

It still recommend my option: using 12V DC to 110V-220V AC and you need 135W.

And what should be the power output/input through the USB-C port?

Firstly please read

Laptops that rely entirely on USB-C, meanwhile, might not charge with just any charger. PCWorld, in its testing, found that HP’s Spectre x2 wouldn’t charge with any USB-C charger besides its own. HP said that that was intentional because a bad charger could damage the device, or cause it to malfunction. Other devices, like the Apple MacBook Pro, don’t have such tight restrictions — a new USB-C authentication system could help with this issue in the near future

That means you need a compatible charger. HP does have

Looks like it needs at least 65W. But it uses AC directly. Many people on this forum say they need more wattage for machines with dedicated GPU. I believe HP does not have 12V to USB-C product(s) at this stage.
