Charging a HP Spectre using a power bank

[littleb999]

Hey guys

I'm trying to make use of the USB-C connectivity and mobility of the HP Spectre 13 by charging it with a powerbank.

The regular charger reads an output of 5V 2A / 12V 3A / 15V 3A

The power bank I'm trying to use is EC technology linked below, it produces an output of 1A , 2A or 2.4A with a capacity of 3.4V 22400 mAH / 82v8Wh

I tried using it to power the laptop and it fails to charge, is it because of the low voltage?

Are there any powerbanks made specifically for charging ultrabooks?

Thanks

Ahhh... YEA!

Your power bank puts out 5V and the laptop requires 12/15 volts?

HP locked down the USB C charging ports so only their chargers work on them. Powerbanks won't work. See article: http://forum.tabletpcreview.com/threads/hps-usb-c-charger-lock-crisis-explained.69523/
