I am trying to find out if the yoga 3 pro has the ability to be charged using a power bank and the original lenovo power cord ( usb adapter). The power bank i am trying to use is a unifun power bank i have also tried the mophie with the dual usb port for smartphone/tablet.
The specs for the unifun power bank are
▪Out2: 5V/2 .1A(MAX)
Or if there is a power bank out there that does charge the yoga 3 pro what is it?
Solved! Go to Solution.

Good day and welcome to the community.
The Yoga 3 Pro looks for 20V input, 4x what that power bank can output. Also, the proprietary cable has extra contacts.
There may be power banks that can supply the proper voltage, but I think it unlikely that one has the proprietary receptacle configuration to match the cable.

There is no power bank we've seen, to date, that offers the extra two leads which supply the 20V that is required to charge the Yoga machines. The cable is proprietary.
