From Cook Islands to Sri Lanka
When travelling from Cook Islands to Sri Lanka: None of your Cook Islands plug types fit in Sri Lanka. You will need a travel adapter. Voltage is different (240V → 230V). Check your charger label; if it doesn’t list 230V you’ll also need a voltage converter. Frequency is the same at 50Hz.

About electricity in Sri Lanka
Sri Lanka uses 230V/50Hz with Type G sockets, the British three-pin standard.
Grid & history
Sri Lanka relies on hydropower from the central hill country, plus coal (Norochcholai) and oil. The 2022 economic crisis caused severe load-shedding; supply has improved but remains tight.
Availability
Reliable in Colombo and tourist areas. Occasional scheduled outages during dry seasons.
Sockets & hotels
Type G is the modern standard. Some older buildings still have Type D. Bring a universal adapter for older guesthouses.
Energy mix
Hydropower is the largest single source.
Practical tips
- A Type G adapter is essential for any non-UK plug.
- A power bank is useful during dry-season outages.
