T470s USB Type-C charging via powerbank?



recently bought a T470s, very happy with it so far. Tried out USB Type-C charging from my powerbank and it doesn't react. Is it the cable, the power bank or is it possible to charge through powerbank at all?
Powerbank 10000 mAh, 3.6 V, 36 Wh
Input 5.0 V/2.0 A
Output 5.1 V/2.1 A
Cable - random 2$ Male USB 2.0 - Male Type-C adapter
PS. If it's not possible to charge via powerbank, why would you give it a type-C port at all... Nobody is ever gonna use it for type-C AC power adapter, cause the port is on the right hand side... *palmface*

Re: T470s USB Type-C charging via powerbank?

USB-C supports many voltages and there is a protocol for the power supply and the device to negotiate the requirements.  You have a laptop that needs 20V and a power bank that only outputs 5 volts.  If you look at your charger that came with your laptop, it can output 5V for your phone or 20V for your laptop.  (also 9V and 15V)  You need a better or smarter powerbank
