Hi, does anyone know if US electrical products will work in Jamaican
According to this website:
The US uses 120V/60Hz, and Jamaica uses 110V/50Hz.
Both countries use identical physical outlet/plug shapes.

And clocks won't keep good time, at least the ones that run on motors.
(They actually keep track, I'm told, at the generating plant to make
sure the average frequency is exactly 60Hz, so that clocks will keep
If emailing, please let me know whether
or not you are posting the same letter.
Change domain to erols.com, if necessary.
And I'm not too sure I'd want to try to run a computer on a 50 Hz supply.

Nobody ever left footprints in the sands of time by sitting on his butt.
And who wants to leave buttprints in the sands of time?
It depends on what you run , some things need 60hz. Id also be
concerned that their 110 drops to 100 or below your apliances
requirements. Bring a volt- Hz meter, a Kill A Watt. Voltage-hz
requirements are often printed on equipment or in manuals.
Thanks Tony! I want to send someone some ultrasonic pest repellers. They are
small appliances, the size of a fist or hand. You plug them into an outlet,
and they emit ultrasonic signals to scare away mice and ants. They click
every few seconds and flash a small red indicator light. they don't draw a
lot of power.
...Sometimes more than just warmer.... Some appliances will smoke and
burn out when plugged into 50 Hz vs. 60 Hz, even though the voltage is
the same. (I saw this happen to a word processor typewriter once.)
The inductive reactance in the primary of the transfomer is less at
the lower frequency, hence more current and more heat....
Computers, especially laptops are generally safe as they often have
"universal" power supplies that accept anywhere from 100 - 250 volts,
50 or 60 Hz.
Desktop computers often have a switch on the power supply to select
between 120 V. 60 Hz and 220 V. 50 Hz. A replacement cordset is
often needed to fit the foreign sockets, though.
For small electronics like recorders and handheld radios, you can buy
3-6-9-12 VDC wall wart power supplies that plug into the foreign
countries outlets. 12 VDC is 12 VDC anywhere in the world.
Clocks may or may not be sensitive. The older electric gear driven
clocks are frequency sensitive and will not work properly. Certain
electronic digital display clocks (Radio Shack?) use the power line
frequency as a reference and hence will not work, yet others will run
fine as they have in internal crystal timebase.
Heating appliances generally do not care about frequency unless they
have some electronics associated with them (The electronic timer in a
coffeepot, for example).
No one can accurately answer your question without the exact
numbers on that appliance. All appliances list their voltage
limits, frequency limits, etc on a label adjacent to where
power enters. That label is important and required. Some
appliances will work just fine at 110 volts 50 hz. Others
will slowly or quickly self-destruct - maybe even become a
fire hazard. Anyone who answered your question without first
obtaining those numbers on the label is only speculating.
First post those numbers. Then get an accurate response.
