It looks to be powered through a cord going into a socket on the wall. As far as I know IKEA does not sell those cords nor those sockets, let alone the electricity delivered through these so this is not an IKEA-powered home lab. That does not mean such a thing is not possible, at least not for those using SBCs. The solution used to be called 'IKEA KOPPLA' ('connect') but for some reason is now called 'IKEA SMÅHAGEL' (small hail) [2,3]. This 3-port USB charger works fine with all Raspberry pies I've thrown it at even though RPi3 sometimes complains about low voltage (which can be ignored and disabled if required as long as you're sure the power supply does actually provide enough power). Here [1] is an example of such, a file/print server I made for my daughter when she started university a few countries away from home, the empty space is now partly filled with a 2TB USB SSD (WD Elements SE Portable SSD). All of this runs fine off a single SMÅHAGEL output even though these theoretically can only deliver 2.4A (2.68A according to the formula presented on the datasheet for the current limiting chip TD 9521 [4], ILim=120k*1.14V/Riset where Riset is 51K in this charger). If this were to become a problem it would be possible to use two outputs but thus far I have not needed to do so.
