I'm going to be fitting 2 powerline adapters with an AC socket on the front of them (TP-Link TL-PA251), but I've now discovered that I'll need an extra 2 sockets instead of just the one on the adapter itself. Is it possible to put a 2 or 3-way adapter, such as: http://www.amazon.co.uk/Masterplug-Indoor-MSF3-NK-MS-Adapter/dp/B001GBTMEW/ in the PL's socket or are they only really designed to carry one device plugged into them? An extension lead wouldn't be an ideal alternative as there is a lack of space where the PL will be plugged in. The 2 extra sockets I need are for the cordless phone charger and the wireless router.
