Thanks for your purchase from Zerolemon and sorry to hear your trouble.

Please note that the Type-C port of this power bank can work as output port and also input port.

When you use the power bank to charge your PC, please plug the charging cable to the power bank first, and then your PC. 

So the power bank will start charging your PC.

Or, if you connect your PC first with the cable, then your PC will charge the power bank, instead of being charged.

Any other concern you have, just feel free to contact us!
