THE TPL-421E2K

Size-wise the TPL-421E adapter is roughly the same as many others with a built-in power socket (123mm in height, 75mm in width and 61mm in thickness).

Each adapter has three long activity LEDs at the front corresponding to power (on/off), Ethernet connectivity and powerline connection.

It was good to see that the built-in electrical socket has integrated child safety protection.

At the base of the adapters we see the RJ-45 Ethernet port, sync button (connects adapters together) and a reset switch.

Contact information for TRENDnet can be found on a sticker placed at the rear of the adapters (the product serial number and barcode are also present).
