I recently purchased a Zbook Studio for video editing, and am wondering how to charge it through a power bank. I initially thought of using usb-c but then I read that you cannot charge through this port. The battery life isn't too great on this computer, so when I go to take trips to Yosemite it only lasts a few hours of editing until I have to find a wall port somewhere. I want to charge from a usb-3 power bank, and am wondering how to do this without a larger battery that has a wall power port. Thanks!

The ZBook Studio has 2 usb-c ports that are thunderbolt capable, which means they support PD (Power Delivery). However, the usb-c 3.1 gen2 protocol standard only allows UP TO 100 Watts of PD into the laptop. The ZBook Studio (like the ZBook 15 G3) requires 150 Watts to charge the device. This is why only the Power supply provided by the laptop OR the HP Thunderbolt dock can support charging of the Studio. There may be other options, but any would require the barrel connector for charging
The TB dock has both usb-c/barrel connector in the connecting cable - usb-c for docking needs, the barrel for charging. The same dock, when configured for standard HP laptops, only has a usb-c connector (hp folio g1, hp elite x2 1012 tablet)
USB 3 has really no means of supplying power back to the laptop

I would like to connect the Zbook Studio to the new cintiq pro 16 that comes with 3 thunderbold 3 ports and needs 30w to work
I read that Zbook studio can deliver 15w through his thunderbold 3 port
Could I connect two cables from the hp to the cintiq using two thunderbold 3 ports ( 15w + 15w = 30w ) ?

PD (Power Delivery) of the USB-C (USB 3.1 Gen 2) standard allows up to 100 Watts to be delivery into the device (laptop, tablet, etc.). It is NOT a power output feature to power devices. The ZBook Studio requires 150Watts to power and charge the battery, and the standard only allows up to 100 watts for PD, so HP's 150W Thunderbolt dock supplies a usb-c and barrel connector cable (molded together) to properly power the workstation and supply the docking needs
it is possible the Cintiq input device to be powered by one of the USB-C ports but not sure if it has the 30Watts required for power output to the device. you may have to try it

Thank you for the fast answer .
I read in the Zbook Studio specs that thunderbold 3 can deliver only 15w to other devices . For that reason I thought that maybe using both thunderbold 3 ports to the cintiq ( has 3 thunderbold 3 ) could deliver 15w+15w and deliver the 30w that the cintiq needs .
I don´t know if on the same time 1 of the thunderbold 3 port from the hp will send the display signal to the cintiq pro 16
( The cintiq it is a monitor/tablet )
Thank you again and a greeting
