If your laptop turn off automatically for several seconds or minutes, it may caused by overcurrent/lowcurrent protection.

How Can i Know Whether My Laptop Will Cause Power Bank Overcurrent or not?

Please Check the label pasted on the adapter, if it is more than 130W (DC output current is more than 7A). it may cause our power bank turn off during charging for overcurrent. so we do not suggest to use our power bank to charge your laptop.
