Hello,

All the TP-Link powerline adapters are compatible with each other, while you buy the TL-PA8010P as the starter kit, then the 8 series will be recommended.

You can refer to the case 2 of the instruction below:

Meanwhile, cause the powerline adapters are sold as a kit usually, few of them are available as a single one, like the TL-WPA8630P, you need to check if you can find a single unit in the local market.

May it help and have a nice day.
