What is the electricity/voltage in the Dominican Republic?

Generally the electricity operates at 110 volts (like in North America) but voltage irregularities are quite common here – sometimes providing less, sometimes providing surges of far more. For this reason, expensive appliances and computers should have surge protection if they are going to be used here. Appliances from countries that use more voltage, 220 volts for example, will generally require converters or adapters.
