Voltage

Take care: Guam uses lower voltage than Montserrat (Leeward Islands)

Your electric devices from Montserrat (Leeward Islands) will be expecting 230 Volts, but Guam grid is of 110 Volts, this is a substantial difference that requires you to take some extra steps in preparation to your trip:

On the positive side, nowadays many devices will switch automatically to the network voltage and they will work just fine, i.e. mobile phone chargers are typically multi-voltage (but please, do actually check your own). It is important that you pay attention to your device's voltage. Connecting electronics to the wrong voltage, in the luckiest of the cases, the device will break or stop working temporarily; but please don't take this lightly, in the worst of the cases electrocution and fire hazards are a real possibility.

An automatic power supply suitable from 100 Volts to 240 Volts. An automatic power supply suitable from 100 Volts to 240 Volts.

High-power devices don't usually handle different voltages due to the high-currents involved i.e. anything that its main purpose involves generating heat (or cold) like hair driers, baby bottle warmers, kettles, etc. On the contrary, modern low-power devices are likely to auto-detect and auto-adapt to different voltages i.e. usb chargers, laptop chargers, etc.

A hair-dryer showing its consumption of 2000 Watts at 220 Volts A hair-dryer can consume up to 2000 Watts, like the one in the picture above, due to the high power they usually work in one voltage system; this one is suitable for 220-240 Volts systems.

You will need a step down voltage converter a device that can be plugged to 110 volts and it provides an outlet with 230 volts for your Montserrat (Leeward Islands)' device. You will need to pay attention to the maximum power output of the converter and the maximum power consumption of the device.
