Do I need a power adapter, and what plugs does Morocco use?

Yes, almost certainly — and this is the small thing that trips up otherwise well-organised travellers. Morocco runs on the European standard: Type C (two round pins) and Type E (two round pins plus an earth pin), at 220–240 volts and 50Hz. If you're coming from continental Europe, your plugs slot straight in and you can stop reading. Everyone else needs an adapter, because UK three-pin, US/Canada/Mexico flat-pin, and Australian angled-pin plugs simply won't fit the round Moroccan sockets.

The part people confuse is adapter versus converter. A plug adapter only changes the shape so your pins fit the wall — it doesn't change the voltage. The good news is that the vast majority of modern electronics (phone chargers, laptop bricks, camera and tablet chargers) are dual-voltage: look for tiny print reading 'INPUT 100–240V' and you're safe with just a cheap adapter. The devices to watch are high-wattage single-voltage appliances — some hair dryers, straighteners, curling irons and travel kettles rated only for 110–120V. Plug a US-only 120V hair dryer into a Moroccan 220V socket and you'll fry it (and possibly trip the riad's circuit). For those you need a voltage converter, or better, buy a dual-voltage travel version before you go.

Practically, I tell clients to bring one universal travel adapter plus a small multi-USB block. Hotel and riad rooms, especially in older medina buildings, often have just one or two accessible sockets, sometimes in awkward spots, so a single adapter feeding a multi-port charger keeps your phone, watch, camera and a power bank all topped up overnight without a tangle of adapters. A short extension lead or a power strip is a genuinely smart pack for groups sharing a room.

One more field note: power in remote areas and desert camps can be limited or generator/solar-based, sometimes only on for set hours in the evening, and the sockets are still Type C/E. Charge everything fully before you head into the Sahara or deep Atlas, and carry a power bank — you don't want your camera dying as the dunes turn gold at sunset. In the cities you'll have no trouble at all; it's purely the plug shape, and occasionally an old appliance's voltage, that you're planning around.
