USB type C charging

[Vatexa]

Is it possible to slowly charge my laptop with A USB-C charger?

Hello Vatexa,

If an HP laptop has a USB-C port but did not come with a USB-C charger, it is generally not recommended you try to buy a charger and see if it works as it is highly unlikely it will. Unless you get firm confirmation from HP for the USB-C charger, it's recommended you stick with your current charger.

On some HP laptops with an included USB-C charger, they sometimes seem to work with 3rd party chargers but may charge slower if the output power is lower and may cause compatibility issues.

Hope this helps,

Eddy

Hello! if I plug the charger into my laptop into the USB type-c port, will my laptop not fail? My laptop HP Pavilion Power 15-cb038ur 3FY78ЕА. Thanks for the info!

Hello @nethill,

Nothing will "fail" but my guess is that a USB-C charger is unable to charge this device. 

The USB-C port is described as being capable of "Data Transfer up to 5 Gb/s, DP1.2, HP Sleep and Charge". Please don't get confused by the "HP Sleep and Charge" part. It's quite misleading and I did try to get HP's attention with this matter.

Furthermore, your current AC adapter is 150W while the max USB-C PD output is only 100W therefore even in the best case scenario, the charger would be providing a slower charge.

Best regards,

Eddy

Yes the "Charge" in the port description is very misleading. It means it provides a charge OUT to something like a cell phone, not a charge in. With no circuitry to accept a charge in you can hook up a USB-C charger but risk damage to the laptop at worst and futility at best. In other words, nothing will happen.

Thanks for answers!

But, what do you say about this:

Hello @nethill,

I can confirm with HP Documentation that the HP Pavilion Power - 15-cb038ur is compatible with the HP 22400mAh Power Pack 1AJ42AA.

However, this is a power bank designed to charge your device through the designated power port, not through USB-C. 

Let me just ensure with an employee that this setup will work because the employee made it seem like the power bank mentioned in the thread you posted is not compatible with the device of the OP (in that thread).

Kind regards,

Eddy

I think I understand what you're saying but my question is why?  They know this is exactly what we want, to basically charge your laptop anywhere from anything via usb C.  Isn't this what the whole thing is about?  This is the 21st century.  We're on the the go.  It's easy to find a charge port at home.  If you're away from home, the last thing you want to do is drain your laptop to charge something else.  I want power coming in, no matter how slow.

According to HP,  "Some 2015 or newer HP commercial notebooks can draw power from an external device such as an AC adapter, at different input voltages such as 5V, 9V, 10V, 12V, 15V, and 20V voltages. Not all voltages are supported on all models."

Which models would those be?  

It doesn't outright say it can take a charge through usb C but why why wouldn't it?  At the very least this is misleading and bad business practice.
