Product: HP USB-C Essential Power Bank
I recently purchased an HP USB-C Essential Power Bank to supplement the battery in my laptop. There is almost no documentation with the product. How do you re-charge the battery? I connected a cable with a USB-C connector on one end and a USB-A connector on the other to the USB-C port on the side of the battery. I connected the USB-A connector to every charger that I have and to the laptop. No lights come on the charger itself and only one status light comes on when I press the status button, no matter how long I leave it plugged in. Do I need to use a cable that has USB-C connectors on both ends and a USB-C charger?
