![]() Photo: CUI Two Conductor Versus Three Conductor Japanese Type A plug with two narrow spades (left) and North American Type A plug with narrow and wide spades (right). Some wall mount power adapters have a similar feature, but instead of changing the ac power cord, the ac blades are interchangeable to accommodate different regions or countries. With these products, it is possible to connect to different styles of wall sockets (in other regions or countries) by changing the ac power cord to one with the appropriate wall plug configuration. Many products with ac power cords have a standard ac inlet at the product chassis into which the power cord is connected. Different ratings often employ physically different connector contacts such that mismatched plug and socket combinations cannot be engaged.įor desktop adapters, the ac connection is a cord, whereas a wall plug adapter will have an integrated plug. The maximum current rating for the connectors is also standardized. Since wall plug voltages are standardized, the ac power connectors are similarly rated to provide sufficient insulation for the standard voltages. Most countries have well-defined plug and socket combinations, voltages, and frequencies. Let’s explore common ac and dc input and output power connectors and how they are used.Īc wall plug selection is typically straightforward and comes down to two criteria: In what regions and/or countries is the power supply intended to be used, and does the application require two conductors or three conductors. ![]() Dc output connectors are much less standardized, and therefore only a commonly available subset of the connectors will be discussed. Single-phase ac-dc wall plugs and desktop power supplies with ac wall plugs (input) and dc power connectors (output) are standardized, as are the associated voltages and maximum currents thus, the discussion regarding those connectors is greatly simplified. Traveling to Vietnam soon? Don't miss out on our ultimate local insights.Power supplies have both input and output voltages and thus often have associated input and output connectors. Alternatively, you can borrow one from your hotels/hostels. If you have already landed in Vietnam, you can buy converters or adapters at bookstores and convenience stores and the price is approximately $4 per adapter. You don’t need to worry too much about the voltage as the majority of the world use 220-240 volts, a similar voltage to Vietnam. If you come from the rest of the world (except some areas in the Philippines, Peru, South Korea, and Brazil) Otherwise, you need a transformer to convert the voltage from 110 to 220 volts. If so, it is okay to use them as long as you have the right plug. You need to check the back of your devices to see if it says something like “100-240, 50-60Hz”. Your device's voltage is 110 volts and is different from the electric system used in Vietnam. You can use them anywhere as long as the plugs are also compatible. But what does it mean to you? If your device says something like "100-240, 50-60Hz", it means it is compatible with all of the different voltages used in the world including Vietnam. Vietnam's electricity voltage is 220 Volt at 50Hz. You need to understand the electricity voltage and frequency too. However, even if the plugs fit, it does not mean they can be used in Vietnam. Forcing the plug can result in damaging it and causing a safety hazard. You should only do this as a last resort. However, if your power plug only has 2 pins (doesn’t require a grounding hole), it still can be used if you force the plug hard enough into the outlet's sockets. If you are from Australia, NewZealand, South Africa, Argentina, or parts of China If you are from the UK, Ireland, Cyprus, Malta, Malaysia, Singapore or HongkongĪlthough type G plugs (British) with 3 rectangular pins can be used in Vietnam in some places, it is less common and in most cases require an adapter. If you are from North and Central America or JapanĪlthough your plug can be used in Vietnam, it is important to check the voltage compatibility highlighted below. Lucky! Your power plugs are similar to the ones used in Vietnam. If you are from Europe with the exception of the UK Power plug type A: 2 vertical pins Power plug type C: 2 round pins Power plug type F (also known as Schuko plug): 2 round pins The below 3 powers plug heads can be used in Vietnam with no difficulties. ![]() Plugs A typical Vietnam electrical outlet ![]() There are 2 important things you need to pay attention to when it comes to electricity in Vietnam: plugs and voltage.īefore your trip, read our 15 essential tips to travel to Vietnam to have the best local advice on visas, time to visit, safety, and more.
