Barbados has a very reliable mains electricity supply operating on a 110 Volts/ 50 Hertz generation system (unlike North America - 110V/60H and the UK 240V/50H).
Most personal electronic devices operate on a DC current via the transformer in their power cord and will work in Barbados.
A back-up generator has been installed at Palm Beach to supply the commercial building and the common areas (elevators, walkways and parking areas) with electricity in the case of power outages. No power is supplied to any of the condominium units.
