Stops charging around 20 percent

The power banks takes over 8 hrs to recharge with a fast charger because of the 30w input. When using a usb-c to usb-c to recharge anything it stops charging around 30 percent. When using usb-a to usb-c to charge anything it stops around 20 percent.

Trash- stops charging at 40%, stopped working after 2 weeks. Doubtful of the claimed capacity as these types of batteries usually mislead and exaggerate capacity. Best Buy return policy SUCKS, so now gotta deal with manufacturers warranty.

When I use this battery with 35% remaining, it will automatically turn off and you will not be able to turn it back on until you recharge it while it has 35% remaining.
