A universal wall socket that accepts plug types A, B, C, D, E, F, G, I and O.
Since Cambodia mixes so many different kinds of plugs and sockets, all wall outlets are universal sockets. There are two types of universal sockets that are used across Cambodia: an ungrounded version (which accepts types A and C) and a truly 'universal' version (see image) that accommodates no fewer than 9 plug types (types A, B, C, D, E, F, G, I and O).
Keep in mind, that despite using American-style plugs, Cambodia's electricity does not run at 120 volts, but at 230 volts. Because of this, tourists from North America and Japan — where the standard voltage is 120 volts — should make sure their appliances can handle 230 V. Always check your device’s voltage specification to avoid any issues: "INPUT: 100-240 V" means that your appliance is multi-voltage and that it will work with any voltage between 100 V and 240 V. Luckily, many travel gadgets (such as laptops or phone chargers) are multi or dual voltage, so most tourists will not have a problem. If your device is single voltage (e.g. "INPUT: 120V"), you will need a transformer to step down the voltage.
