Not sure what the power input for laptop is? 5V i think but at how many amps? I seen 3A for the cpu card... So i guess a 2.4A usb power supply won’t be suitable?
Cus if it will work well from 2.4A 5V input, then i was thinking of getting this usb power supply. 6port version, really nice, efficient : https://www.mymemory.co.uk/anker-powerport-6-2-4a-usb-desktop-charger-white....
