Yes, you can connect several Powerline adapters to this device, i.e. more than one receiver. If you buy the product multiple times, you can connect one adapter to the router and use other adapters around the house, for example three or more.

To integrate additional adapters into your existing Powerline network, you need to press the pair button on an existing adapter and then on the new adapter to pair them. You can then plug the new adapter into the desired location and connect it to your device. This makes it easy to expand the network.

Note that there is a maximum number of adapters per powerline network, which is limited by chipset and firmware. The exact maximum number depends on the model, but for normal home use, several adapters are possible without any problems.
