Sockets will be compatible with most European systems (C, E and F), however other systems will need an adapter.
Electric sockets are mostly the same as for Europe (220V/50Hz), outlets are two-prong European style but not grounded. If your device is compatible with the voltage, there are lots of plug adaptors and power bars available for US-style plugs.
Adaptors (so you can plug in US devices into Egyptian outlets) are available in many stores in Cairo for just 1 LE each. Check on Shara el-tahrir near Midan el-Tahrir if you don't see them elsewhere.
You might be better off buying a multipoint from home though. I am yet to find a multipoint that lasts me over a month, even when just the laptop and wifi transmitter are plugged in.
Could be the absence of grounding in the electrical connections here.
