I intend to use my HP Pavilion Laptop 15-dk0xxx for external usage and I need a solution for power supply for 3-4 hours after battery is charged off.
I think of using a laptop power bank with a capacity of 50000 mAh, with maximum power of 130 watt, for my laptop whose power is 135 watt. My question is if due to the power of the laptop the power bank will be insufficient to properly charge the laptop.
