Owners of DA305 and DA310 adapters have reported issues with charging their computer. This happens when you connect your USB Type-C AC adapter through one of the Dell multiport adapters to your computer.
The computer shows a notification about the computer not charging or that it is charging slowly. There is usually a yellow triangle with an exclamation mark on the computer's battery status icon.

The DA305 and DA310 adapters reserve 15 W. This means that your computer gets 15 W less from any power source that is connected through the adapters. Both adapters only support a maximum of 90 W through the USB Type-C power pass-through to the computer.
We recommend that you always connect your power source directly to your computer.
