Razer blade stealth: power bank charging issues.

[Mars_Flugstad]

Hey, so to start I have had my blade for a while and I love it, the biggest problem I have had is it's terrible battery life.  I can pull 4 hours if I only have like one tab of edge open.  Its ridiculous.  So I wanted a portable battery bank to charge it.  But the razer power bank is only 12,000 mah and its $140.  So I have been looking for other options, I found the imuto power bank: (I chose this one because it was light, I know I could find a heavier more powerful one.)

it has power delivery 2.0 at 20v 2.25 amps (45 watts) which is what the blade runs at.  I have also bought a compatible usb type c cable with power delivery:

but when I plug it in I hear the usb sound like when you plug in a flash drive.  How do I solve this? I have checked and the battery bank charges my phone over usb type a and a Nintendo switch over type C.

Does razer have a proprietary control over what power bank you can use?

Is there a fix so that I can use this power bank?

I have not seen a lot of threads about the stealth and power banks, so I feel like I'm treading in new territory.
