Chewing Minibook

Hi. I recently got the minibook with the M3-8100y processor. I had thought that a power bank was capable of charging this minibook but so far I’ve tried three different ones without any success using the USB c cable. Are there only specific Portable power banks which Can charge this device?

Any powerbank that can charge at 30 Watts with 20V/2amp should be good in charging it. I am using Xiaomi Mi Power Bank 3 20,000mah 50W Max Turbo Charge,
Huawei 12000mah 40W Supercharge Power Bank, Rock 20000mah Power Bank with LED Digital Display 63W PD QC3.0 Fast Charging Powerbank, Lenovo 14000mah Power Bank. These are all that are capable of charging your Minibook

Ok, thanks. I’ll have to do a bit of research before buying a suitable charging device but I’ll look out for some of those. Thanks. Mike
