Type A Plugs and Plug adapters
- consisted of two parallel flat prongs
- neutral prong in the polarized plug it’s wider than live prong, allowing the plug to be inserted into the socket only one direction.
- Polarized type A plugs will fit into new type A and type B power outlet sockets
- Japanese type A plugs do not have the polarized feature, therefore a Japanese plug will fit into a North American outlet, but a North American polarized plug, will not fit into a Japanese power outlet socket.A non-polarized type A adapter it’s needed.

Outlets for Type A
TYPE A Plugs and Outlets
(Used in North American and some Central and South American countries as well as Japan)
Type A plugs are considered class II non-grounded plugs.It consists of two parallel flat pins and it’s standard in countries such as: American Samoa, Anguilla, Antigua, Aruba, Bahamas, Bangladesh, Barbados, Bermuda, Bolivia, Brazil, Cambodia, Cayman Islands, China, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guam, Guatemala, Guyana, Haiti, Honduras, Jamaica, Japan, Laos, Lebanon, Liberia, Maldives, Mexico, Micronesia, Montserrat, Netherlands Antilles, Nicaragua, Niger, Okinawa, Palmyra Atoll, Panama, Peru, Philippines, Puerto Rico, St. Vincent, Saudi Arabia, Tahiti, Taiwan, Thailand, Trinidad & Tobago, United States of America, Venezuela, Vietnam, Virgin Islands, (U.S.& British) Yemen.
The Japanese does not present the polarized feature, which ,makes the 2 prongs Identical in diameter and length. Japanese outlet also have identical receptacles in diameter and length,which might present itself as an issue when trying to plug a polarized US style plug into a Japanese outlet receptacle.Japanese plugs should be able to fit into a American outlet with no problems.
It’s also important to keep in mind that while the US, Canada, Mexico and other countries that often present type A plug and receptacle style operate in 110-120 Volts, Japan operates in 100 Volts. Which means that a voltage converter might be needed. See our Japan Voltage Converters section for more information on these converters
Type A plug does not have grounding, and is still used in most of North America, Central and South America on equipment that does not require a ground connection, such as lamps and small appliances.
Type A plugs are still very common because of their capability to be used with type A (non-grounded) and type B (grounded) power outlets.
NEMA 1-15 power receptacles, are no longer allowed in new construction in the United States and Canada since 1962, but are still sold for replacement purposes.
Rules of Thumb for Appliance Voltage Compatibility
It’s important to understand that there’s no such thing as a “standard” electrical input/output for electrical appliances. The information below is just a general guideline, and it may or may not be correct for your specific brand and model. The only way to know for your specific appliance is to check.
Laptop computer: Usually 100-240V, 50/60Hz, auto-switching. A travel plug adapter works just fine all by itself.
Desktop computer: Usually switchable between 110-120V and 220-240V via a small switch on the back of the computer, near the cooling fan. A travel plug adapter will work fine as long as the voltage switch is set to the proper position.
Cell phone: Usually comes with a charger that is 100-240V compatible, but that is by no means always the case. It’s very important to check the charger. If it says “100-240V” then a plug adapter will work fine. If not, the easiest solution is probably to contact your cell phone provider and buy a new charger which is multi-voltage compatible, and attach the appropriate plug adapter to the multi-voltage charger.
PDA/Blackberry/etc: Almost always comes with a charger that is 100-240V compatible. Simply attach a plug adapter to the charger’s plug.
Digital camera: Chargers are usually 100-240V compatible. A plug adapter is usually sufficient.
Hair dryer/curling iron/flat iron/etc: Most U.S. and Canadian hair care appliances are only compatible with 110-120V, though some higher-end models can be switched between voltages. If your brand/model has a voltage switch, then a plug adapter is sufficient. Otherwise, the appliance will require that the voltage be changed. Since hair dryers and other hair care appliances usually don’t contain any electronic circuits, a voltage converter is usually more convenient than a step-down transformer.
Electric shaver: Most U.S. and Canadian corded electric shavers are only compatible with 110-120V. Cordless/rechargeable shavers often come with chargers that are 100-240V compatible.
CPAP Machine: 50/50 shot, there’s no telling. A lot of CPAP machines are built with DC motors because they’re quieter. DC motors plug into AC power sources, of course, through an AC adapter. Since AC adapters are converting an AC voltage to a smaller DC voltage anyway, the AC input voltage is often irrelevant. If the AC adapter says “100-240V” then a plug adapter will work just fine. But this is by no means true of all CPAP machines. Some brands/models use AC motors and are only compatible with 110-120V. If that’s true of yours, then theoretically a voltage transformer + a plug adapter would at least allow it to power up. But in practice, the difference in frequency (Hz) may negatively affect the machine’s performance. For most appliances, the effect is negligible. But for a CPAP machine, we’ve been told that the effect can be significant. The better solution may be to just buy a multi-voltage compatible CPAP machine, rather than to depend on a transformer.
iPod: You’ll have to check the iPod’s charger. There are so many different versions, it’s impossible to keep up with what kind of charger ships with any particular model. If the iPod’s charger says “100-240V” then a plug adapter is sufficient. Otherwise, if it says “120V” then you’ll need a voltage transformer. Or you’ll need to replace the iPod’s charger with one that is 100-240V compatible.
Audio/Video Equipment, including Televisions, Stereo Components, VCRs, DVD Players, Video game consoles (X-Box, Wii, Playstation, etc.): Most equipment of this type is purposely manufactured to be localized to a particular country or geographic region. It’s all part of the “war on piracy” and for the most part, it’s not worth the trouble to bring this kind of item abroad. Even if you want to fight the battle of getting power to the device, there will probably be compatibility/standards issues related to the audio/video signals, scan rates, etc. These are beyond the scope of our business, and we don’t claim to be authorities on those matters. Television broadcast standards are different (NTSC vs. PAL), audio broadcast standards are different, CD and DVD media are usually “region-locked” to a particular geographic area (i.e. European DVDs/game discs won’t play on most North American DVD players/game consoles) and a host of other issues beyond simply getting power to the device. If you’re dead set on bringing A/V equipment to another country, you’ll want to consult an A/V specialist.
Power Tools: Most U.S. and Canadian power tools are built for 110-120 volts, and will require a step-down voltage transformer as well as a plug adapter. However, some cordless/rechargeable power tools ship with chargers which are 100-240V compatible. Check your charger. If it says “100-240V” then a plug adapter is sufficient.
Air conditioners, refrigerators: Appliances which contain a compressor require a special type of transformer called a “3-tap transformer” because in order for the compressor to function properly, the output voltage supplied by the transformer needs to be slightly adjusted up or down to compensate for the difference in frequency (Hz.)
Clothes dryers and Electric ranges: North American clothes dryers and ranges usually connect to a specialized 2-phase household electrical circuit. You’ll want to consult an electrician.
Using Appliances Abroad:
What do I need to use my appliances abroad ?
They do not convert electricity. They simply allow a dual-voltage appliance, a transformer or a converter from one country to be plugged into the wall outlet of another country. The plug of a Continental European appliance will not fit into an outlet in a foreign country without an adapter.
Converters and transformers both step up or down the voltage, but there is a difference in use between them. Converters should be used only with “electric” products. Electric products are simple heating devices or have mechanical motors. Examples are hair dryers, steam irons, shavers, toothbrushes or small fans. Converters are not designed for “continuous duty” and should only be used for short periods of time (1 to 2 hours). Additionally, most converters can only be used for ungrounded appliances (2 pins on the plug). Converters must be unplugged from the wall when not in use.
Transformers also step up or down the voltage, but they are more expensive than converters and are used with “electronic” products. Electronic products have a chip or circuit. Examples are radios, CD or DVD players, shavers, camcorder battery rechargers, computers, computer printers, fax machines, televisions and answering machines. Transformers can also be used with electric appliances and may be operated continually for many days. The advantage of converters, however, is that they are lighter and less expensive.
Computers are electronic devices and therefore they must be used with a transformer, unless they are dual voltage. Fortunately, most laptop battery chargers and AC adapters are dual voltage, so they can be used with only a plug adapter for the country you will be visiting.
Transformers are sold in various sizes based on how much wattage they can support. Therefore one must pay careful attention to the wattage ratings of the appliances to be plugged into a transformer. The wattage rating of the transformer must always be larger than the wattage rating of the appliance to be plugged into it (plus a 25% buffer to allow for heat build-up in the transformer or converter). When plugging multiple items into a power strip, then into the transformer, you must calculate the combined wattage of all appliances and the power strip, then add an additional 25% to that total.
The appliance’s voltage and wattage requirements are listed on the manufacturer’s label located on the back or at the bottom of the appliance. In some cases, the voltage and amperage will be listed, but not the wattage. If this is the case, simply multiply the voltage by the amperage rating to find the wattage rating (e.g. 230 V * 1 A = 230 W).
Below is a list that gives an idea what the wattage of common appliances is. Use this as a guide only. Always check your appliance first !
- 75 watts: small, low-wattage appliances such as radios, CD players, heating pads, and some televisions.
- 300 watts: larger radios, stereo consoles, electric blankets, sewing machines, hand mixers, small fans and most TV sets.
- 500 watts: refrigerators, hair dryers, stand mixers, blenders and some stereo equipment.
- 750 watts: projectors, some sewing machines and small electric broom type vacuums.
- 1000 watts: washing machines, small heaters, some coffee makers and vacuums.
- 1600 – 2000 watts: dishwashers, most appliances that have heating elements such as toasters, electric deep-frying pans, irons, and grills.
- 3000 watts: heaters and air conditioners.
Transformers and converters only convert the voltage, not the frequency. The difference in cycles may cause the motor in a 50 Hz appliance to operate slightly faster when used on 60 Hz electricity. This cycle difference will cause electric clocks and timing circuits to keep incorrect time: European alarm clocks will run faster on 60 Hz electricity and American clocks will lose some 10 minutes every hour when used in Europe. However, most modern electronic equipment like battery chargers, computers, printers, stereos, DVD players, etc. are usually not affected by the difference in cycles and adjust themselves accordingly the slower cycles.
