This article provides the USB-C power supplies for the I-Series 4.0 Devices

All I-Series 4.0 Android devices support video, audio, and touch via a single USB-C cable. The 15.6-inch and 22-inch models can also power up to an Elo 1502L touch monitor through USB-C when used with the Elo 90W power supply.

If you're adding a USB-C monitor as a secondary or rear-facing display, you'll need the optional 90W Replacement Cable Kit (which includes NA & EU power cables and a 90W power brick), part number E572635.

However, if no secondary display is being added, the standard 65W Power Brick, P/N: E514304, will be sufficient.

For more details on USB-C and power delivery, please refer to the I-Series 4.0 User's Manual.
