Cambodia has a plug and socket from most western countries so you’ll see sockets and plugs that look like these. A simple adapter to match mismatched plugs and sockets are as little as $1. The power used in Cambodia is 220VAC and 50Hz step down transformers and power stabilizers are readily available. Due to the poor stability of the line voltage a uninterruptible power supply is recommended for any devices which may be damaged by the voltage variances.
Did you know that the reason some countries use 60Hz is because 60Hz is 30% more efficient than 50Hz and the reason we use 50Hz in Cambodia is because the French didn’t like 60Hz because it didn’t fit into the metric system. Makes you wonder why the French still have 24 hour days.
