AC To 12V Adapter Buying Guide

AC To 12V Adapter Image
Picture: 300W Power Inverter DC from BESTEK

Many portable electronics and appliances run on 12-volt DC power. They do so because most vehicles have electrical outlets that supply 12 volts. You'll need an AC-to-DC adapter if you want to run such equipment in your home or office without using batteries. This accessory plugs into a standard wall outlet.


If you have the right type of adapter, you can use a wide range of car-oriented appliances while remaining indoors. These machines range from air compressors to portable coffee makers. Other 12-volt devices include heated mugs, hand-held vacuum cleaners, fans, Boomboxes, small TVs and certain tablet computers.

Ampere Limit

It's particularly important to pay attention to the maximum amperage when you compare adapters. Different models' limits generally range from 300 milliamps to 15 amps. Look at your electronic device, its DC power cord and the instruction manual to find amp requirements. This data probably appears in a list of specifications.

Some brands specify a maximum number of watts rather than amps. For example, your portable fan might have a panel that reads "12V, 15W." You can multiply 12 volts by the maximum number of amps to discover an adapter's wattage limit; a two-amp unit will power devices that need up to 24 watts.

If an AC-to-DC converter can deliver more amps or watts than your equipment needs, it won't cause any harm. On the other hand, serious problems may develop when you try to power a machine with an adapter that doesn't supply enough amps. Call a device's manufacturer or visit its website when you can't find the electrical specifications.

Input Voltage

If you never leave North America, feel free to buy a converter that only runs on 110-volt AC power. However, a number of foreign countries use higher voltage levels. They include China, India, Russia, Germany, the U.K. and others. An adapter that accepts 110 to 240 volts will benefit global travelers.

Plug Styles

Most of these converters have North American two-prong plugs. If you plan to travel abroad, you can order a model with a plug that fits EU or British outlets. An alternative is to buy a separate international outlet converter and attach the AC-to-12V adapter to it when you venture overseas.

The shape of the DC output connector also varies. Most adapters have sockets that resemble the cigarette lighters in vehicles. Other models use small round plugs or alligator clips to deliver 12-volt electricity. Remember to select a product that's compatible with your device's power input terminal.

A few adapters offer USB ports in addition to conventional DC outlets. These jacks supply five volts rather than 12. They can power or charge a wide variety of small gadgets. This feature greatly increases an adapter's versatility. However, some people already have access to more than enough USB charging ports.

Output Voltage

Most of these adapters exclusively deliver 12-volt DC power, but some models can operate at other voltage levels. Users set the number of volts by adjusting the position of a switch. The output level typically ranges from three to 12 volts. These universal adapters are versatile but tend to have relatively low ampere limits.

Cord Style

Many converters feature compact one-piece designs with integrated plugs and no wires. Others have separate AC and DC cords that attach to a rectangular transformer. The cord length usually ranges from three to eight feet. A converter with long wires will let you use 12-volt equipment in a greater variety of locations, especially if your device has a short built-in cord.

Some adapters have detachable AC electrical wires. This design proves beneficial if you eventually decide that you want to use a longer or shorter cord. It also allows you to easily replace the wire if its plug or rubber coating becomes damaged.

Power Switch

Only a few adapters have switches that allow owners to turn them on and off. This feature comes in handy when you need to use a device with no power switch of its own. It will reduce wear and tear on the adapter and outlet.


A number of AC-to-12V converters have small indicator lights. Thanks to efficient LED technology, they consume a negligible amount of energy. A light will remind you to disconnect or turn off a device when you finish using it. These indicators may also help you diagnose any problems.


A shoddy adapter might fail, overheat or supply the wrong amount of energy. It could damage your equipment and increase the risk of a fire. Some poorly made cords and plugs can quickly deteriorate with regular use. Be sure to look for a certification from UL or an equivalent organization.


Adapters usually include guarantees that remain in effect for 12 to 24 months. A few brands supply lifetime coverage, and some retailers will provide a supplemental warranty when you pay a fee. Keep in mind that a guarantee might expire early if you don't remember to complete the product registration form.


Prices generally range from $5 to $40 and vary depending on the product's quality and capabilities. A high-amperage adapter normally costs somewhat more than a unit that only delivers one or two amps. Lengthy cords and USB ports may raise the price as well.


Every converter model is appropriate for a different group of buyers. If you just want to use a radio, portable light or other low-wattage device at home, try to find a basic adapter with no extra features. You don't need a high amp capacity, but a fairly long cord might make your life easier. International travelers may prefer one-piece cordless converters that accept multiple AC voltage levels.

On the other hand, spend some extra money on a more capable unit if you want to power a demanding machine. Things like tire inflators and cooking appliances draw numerous amps. Either way, don't forget to look at certification details and read reviews. It's crucial to find a well-made adapter that will safely power your equipment.
