Electricity
Bonaire, Curacao, and Jamaica have two things in common. The first is that they are all located in the Caribbean. The second is that they share the same electrical power characteristics. The default power from an electrical outlet here on Bonaire is 127 Volts AC at 50 Cycles (or Hertz or Hz). This doesn't really match either the power requirements of most European appliances (220V, 50Hz) or American appliances (110V, 60Hz), and while both European standard and U.S. standard outlet connections are visible in just about all Bonairean structures, it's not always clear what voltage the outlet is running at, so it's important to check this with whomever operates the house, hotel, apartment, etc. that you'll be staying in.
Assuming you have a 127V outlet (which looks like a U.S. standard outlet typically), most resorts have transformers available for rent for your more sensitive plug-in appliances, such as battery chargers. Such transformers can also be bought in local stores such as Kooymans, Inpo, and Playa Trading for between $50 and $100.
Some things may be plugged into a 127V socket directly without a transformer, as long as you understand that some U.S. voltage specific devices may run warm, and may burn out if left plugged in for a long time. Note that many notebook computers already have universal power supplies and should work fine plugged into any outlet (check with your manufacturer or your notebook power supply for details) .
However, it is also said that Bonaire is occasionally "generous" with its power, and surges and brownouts are not uncommon. If you plug anything electronically delicate into a wall outlet, it might not be a bad idea to have a small surge protector in between. These are available at most consumer electronics stores, such as Radio Shack.
