Charge your 12V devices using a regular wall outlet without any trouble. This is possible because of an AC to DC converter. It allows you to use your gadgets freely at home, work, or when you’re out and about.

Now, Here are the top 3 factors to consider before purchasing an AC to DC converter.

  • Power Requirements: Determine the power consumption of each device. This is usually stated in watts (W) or amps (A) on their labels or user manuals. Add the power consumption of all your devices gives you the total power requirement. Select a power converter that can handle this total power requirement. 
  • Compatibility and Connectors: Ensure the converter is compatible with your devices, including voltage, current, and connector types.
  • Safety and Protection: Look for safety features like overload, overcurrent, short-circuit, and over-temperature protection.

Buying Guide for Best AC to DC Power Converter

AC (Alternating Current) is the electricity that comes from your wall socket. If you need an adapter for a device, it might be to either lower the voltage of AC or to convert it to DC (Direct Current).

DC flows in one direction, while AC switches back and forth. The electricity from the wall is usually around 100 to 240 volts, and it alternates at a frequency of 50 or 60 times per second. These standards are followed in the USA. 

1. Volts

When it comes to voltage (measured in volts), you might encounter a range like 1.5 to 24 volts for various products. Any voltage within that range will work fine.

If you’re dealing with audio devices, it’s a good idea to choose the higher voltage option if it’s available, as it can provide optimal performance. However, for most devices, using a twelve-volt adapter is usually sufficient.

2. Regulated vs Unregulated Power Supply

Regulated converters maintain a constant output voltage, while unregulated ones may fluctuate based on the load. For sensitive devices, a regulated power supply is recommended to prevent voltage fluctuations. For devices like some small appliances, toys, or lighting, an unregulated power supply is recommended.

3. Amperage

If you opt for a regulated power supply, make sure it can provide 2000 milliamps or more. If an adapter can only deliver 1000 milliamps,  it can lead to overheating or even a fire risk. However, if your devices need 1000 milliamps and the supply can deliver 2000, it can handle the current without any issues. Having a bit more amperage isn’t a problem, but never go below what the device requires.

4. Current Type & Polarity

Polarity indicates the direction of the electrical current flow. When you examine a product, such as an adapter, you’ll notice the centre pin. In some cases, it’s positive, but it can also be negative. To match this, you’ll need an adapter with a centre pin that’s positive if your product requires it.

It’s essential to keep in mind that since AC power alternates back and forth, AC plugs don’t have polarity.

5. Plug Size

To determine this, you’ll need to measure the pin and barrel size in millimetres. In most cases, the barrel size is around 5.5 mm. As for the pin size, it can vary, but a common pin size is either 2.1 or 2.5 mm, so those are usually a safe choice.

Consider using multi-adapters as they can be quite handy in situations where you encounter different plug sizes.

6. Safety Features

Look for safety features such as overload protection, overcurrent protection, short-circuit protection, and overheating protection. These features can safeguard your devices from potential damage.

AC to DC Power Converter – FAQs

1. What is the easiest way to convert AC to DC?

Ans: The easiest way to convert AC (alternating current) to DC (direct current) is by using a rectifier, which can be as simple as a diode or a bridge rectifier circuit.

2. Can AC to DC converters regulate the output voltage?

Ans: Some AC to DC converters, like switching power supplies, can regulate the output voltage, providing a stable DC voltage regardless of input fluctuations.

3. What are the applications of AC to DC converters?

Ans: AC to DC converters are used in numerous applications, including charging devices, powering electronics, supplying energy to industrial machinery, and more.

4. Can I build my own AC to DC converter?

Ans: Yes, it is possible to build a basic AC to DC converter using diodes and other components, but for more complex and high-power applications, it’s recommended to use commercially available converters.

5. Can AC to DC converters be used for renewable energy systems like solar panels?

Ans: Yes, AC to DC converters are commonly used in solar inverters to convert the DC power generated by solar panels into usable AC power for homes and businesses.


Certainly, based on the top 3 recommendations and considering common user preferences, here’s a summary:

  • Suacopzar AC to DC Converter can be considered a budget-friendly choice for those looking to power low-power devices and not high-power ones. It is suitable for products with a rated power of less than 24W and a maximum current of 2A.
