Dell 7840 slow charging

Hello, i've problem with my Dell 8 7840 charging. When i'm charging with wall charger, tablet shows that it's  "usb charging" instead of "AC charging". And charging time is very slow. It takes for about 10-12 hours. I tried different chargers, but nothing helped. Having any ideas?

Thank you for writing to us!

There would be issues with the connector / Ac Adapter port or there could be an issue with the battery or the operating system. Kindly check if there are any damages or bent pins on the tablet or the adapter.

Kindly private message the service tag and email address.
