Zanzibar Power Plugs, Wall Sockets & Electrical Outlets
In Zanzibar, power plugs and sockets (electrical outlets) of Type D (BS 546, three large round pins in triangular pattern, grounded) and Type G (BS 1363, three rectangular pins in triangular pattern, grounded) are used. Wall sockets run at 230V and 50Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Zanzibar.

Zanzibar Travel Adapter Guide
A Zanzibar power plug follows the British-derived electrical standards still used across much of East Africa, meaning visitors from North America, mainland Europe, and much of Asia will need a travel adaptor to connect their devices. Zanzibar's electricity supply runs at 230V and 50Hz, and the island uses both Type D and Type G sockets depending on the building and its age. Packing a universal travel adaptor that covers both pin configurations is the safest way to ensure your AC power plugs and sockets work wherever you're staying, whether it's a beachfront hotel or a local guesthouse.
Dual-Voltage Devices and Zanzibar
Most modern electronics, including phone chargers, laptop power supplies, and camera battery chargers, are dual-voltage and designed to accept anywhere from around 100V to 240V. For these devices, a simple plug adaptor is all that's needed to physically fit Zanzibar's Type D or Type G sockets, since the voltage conversion happens automatically inside the device. However, single-voltage appliances such as hairdryers or shavers built for 110-120V markets will require a separate voltage converter, or risk damage when plugged into Zanzibar's 230V supply.
Power Sockets and Plug Types in Zanzibar
Zanzibar's power infrastructure reflects its historical ties to British colonial electrical standards, resulting in two plug types in common use. Type D, based on the older BS 546 standard, features three large round pins in a triangular pattern and is rated for 5A at 220-240V, making it suitable for smaller household devices but not heavy appliances. Type G, the more widely recognized British BS 1363 standard, uses three rectangular pins and is rated up to 13A, with an internal fuse offering extra protection for higher-power equipment like kettles or hair dryers.
Grounding and the Earth Pin
Both plug types found in Zanzibar are grounded, providing an added layer of safety for appliances and electronics. On a Type D plug, the grounding pin is noticeably larger in diameter than the live and neutral pins, while on a Type G plug the earth pin is the longest of the three and also acts as a safety key that opens the socket's protective shutters. This ensures the earth connection is made before the live and neutral pins engage, reducing the risk of electric shock.
- Type D: three round pins, 5A rating, common in older buildings and some African nations
- Type G: three rectangular pins, 13A rating with internal fuse, widely used in former British territories
- Voltage: 230V, Frequency: 50Hz
- Both plug types are grounded for added electrical safety
Frequently Asked Questions
Yes, most travelers will need a travel adaptor since Zanzibar uses Type D and Type G sockets, which differ from plug standards used in North America, mainland Europe, and many other regions. Bringing a universal adaptor covering both types ensures compatibility across different accommodations.
Zanzibar uses both Type D (BS 546) and Type G (BS 1363) plugs, reflecting its British-influenced electrical history. Type D has three round pins and a 5A rating, while Type G has three rectangular pins and a 13A rating with a built-in fuse.
Yes, both Type D and Type G sockets used in Zanzibar are grounded. Each design includes a dedicated grounding pin, larger or longer than the live and neutral pins, to provide reliable earth protection for connected devices.
In most cases, yes, since smartphone chargers are typically dual-voltage and can handle Zanzibar's 230V, 50Hz supply without a converter. You'll still need a plug adaptor to physically fit your charger into the local Type D or Type G sockets.
