I asked Google what Power Sockets Guyana use:
Guyana uses type A, B, D and G electrical plugs with a voltage of either 110 V or 220 V at 60 Hz. In cases where 110 V current is used, you can expect to find type A and B outlets whereas in cases where 220 V current is used, you can expect to find either type D or G. However, voltages and the frequency of current fluctuate extensively. So, it’s important to verify before plugging in any sensitive electronics.
I ask my Uncle what Power Sockets Guyana use:
"Dis one - . Unless your building is old, then it’s anyones guess.”
