I purchased these items 25 years ago, but I'm selling them because I have duplicates. One item's outer box has been discarded, but the contents are unopened. The other item has been used for a short period. There are small scratches near the plug-in area, but no damage or discoloration. Unopened and used set Approximately 38 x 33 x 30mm Full-Speed Charging Technology Anker's proprietary PowerIQ technology automatically detects connected devices and provides the optimal current needed for the fastest charging, enabling full-speed charging. Simultaneous Fast Charging for Two Devices A total output of 12W is possible from the two ports. You can charge two tablet devices simultaneously. I am not considering selling these items separately or offering a discount. Thank you.
