# Are 12v ac adapters interchangeable?

Looking for an answer to the question: Are 12v ac adapters interchangeable? On this page, we have gathered for you the most accurate and comprehensive information that will fully answer the question: Are 12v ac adapters interchangeable?

The power formula P (watts) = I (ampere) x V (volts) shows you that if for example the needed power is 5 watts and the adapter delivers 12 volts, the adapter must be able to supply a current of at least 0,41 Amps (or 410 mA). There's no risk in selecting an adapter that is able to deliver a current of 1 Amps (1000 mA) at 12 volts.

There's no risk in selecting an adapter that is able to deliver a current of 1 Amps (1000 mA) at 12 volts. The device is not harmed by this. If the current is not enough, voltage might collapse causing slow charging of battery devices or inoperatibility of the device.

As long as the voltage is the same on the adapter and on the device (also, I have 9V DC and 9V AC adapters, do not mix these up) and be sure the current required is less than the amount that the adapter can source otherwise you risk overloading the power supply.

Each AC/DC power adapter is specifically designed to accept a certain AC input (usually the standard output from a 120 V AC outlet in your home) and convert it to a particular DC output. Likewise, each electronic device is specifically designed to accept a certain DC input.

## Are AC power adapters interchangeable?

As long as the voltage is the same on the adapter and on the device (also, I have 9V DC and 9V AC adapters, do not mix these up) and be sure the current required is less than the amount that the adapter can source otherwise you risk overloading the power supply.

– Yes, they are likely interchangeable even though voltage is not the same. This is because the voltage difference is within specs, and I am GUESSING you could go even higher or lower in voltage.

## Is there a difference in AC adapters?

Most AC/DC adapters are not universal and can only be used to power compatible devices. ... These universal power supply adapters are compatible with multiple voltages within a range - for example, 100-240 Volts - and some even feature plugs of different sizes. The latter is also known as star connectors or X connectors.

## What does 12V 1amp mean?

12V 1A, means it can provide the current of 0A to 1A. while maintaining it's 12V. After 1A, the voltage is not guarantee. For the current rating on the product, it indicate the maximum current the product will draws from it's power supply.

## Can you use a 12V 2a charger on a 12V 1.5 a device?

You can use a 12V supply with a higher current rating, but not a lower one. The device will only draw the current it wants, but the supply has to able to put out the maximum current the device wants.

## How do I match AC adapter to device?

The right AC adapter for your device is one with matching electrical ratings. The device's input voltage and current must match the adapter's output voltage and current. Check the device's product label or user manual to see its rated voltage and current.

## What's the difference between 12V AC and 12V DC?

12V DC is safer than 12V AC. Body resistance decreased when the 12V AC still may cause the dead, 12V DC will not be in 100%. However, the hazard degree of electric shock to the human body mainly depends on the size of the current passing through the human body and the length of the energization time.

## Can you swap power adapters?

You can safely use an adapter with the same output voltage, and a current (A/mA) rating equal or higher than the original.

## How do I know if my AC adapter is compatible?

Any AC adapter is considered compatible with any device if it has all the following traits:The voltage of the adapter has to be identical. ... The amperage (amps) of the adapter has to be equal or greater than the device. ... The polarity of the adapter has to be identical.

## Are all 12V adapters the same?

The short version: Voltage (V) should always be the same for both adapter and device. Polarity (plus on the left side or plus on the right side) should always be the same for both adapter and device. Current (A or mA) of the adapter should not be lower than the current of the device but may be higher.

## Can I use 12V AC instead of 12V DC?

simple measurement method: with a stylus pen (non-ordinary pen) on the wire foreskin, 12V AC will still show, 12V DC no display. 12V DC is safer than 12V AC. Body resistance decreased when the 12V AC still may cause the dead, 12V DC will not be in 100%.

## Can I use 12V Adaptor on 8v?

1 Answer. You should never use a significantly higher voltage rating adaptor on any kind of electrical device. If you do so you are risking damaging the equipment and anything else that you might have plugged into it.

## Can I use a 12V 0.5 A adapter with a 12V 1a power rated modem?

Yes. The working voltage matters which connects the power source to any device.

## What happens if you plug DC into AC?

If accidentally AC line touches the DC line connected to the electronic circuit and components, the result may be bad smell smoke, flames or even worse. ... In case of AC components when DC connected to it, it may not work properly (that's why a transformer can't be operated on DC voltage) or even start to smoke and burn.

## What happens if you use 12V instead of 9V?

You can't use a 12V adapter to power a 9V guitar pedal. A pedal that only handles 9V can be destroyed by using a 12V adapter. It's possible for a power supply to ruin your pedal even if you get the voltage right.

## Can I use a 12V 0.5 A adapter with a 12V 1A power rated modem?

Yes. The working voltage matters which connects the power source to any device.

## Can use 12V DC adapter 9V?

If you have a 12V adapter, you might wonder whether you can use it to power your 9V guitar pedals. In most cases, you cannot use a 12V adapter to power a 9V guitar pedal. Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it.

## Are there different AC adapter sizes?

The most common types of connectors are 2.1mm inner diameter x 5.5mm outer diameter female, 2.5mm inner diameter x 5.5mm outer diameter female, 3.5mm male, and even screw terminal connections (Remember to also match center positive or center negative plugs).

## Can I use a 5V adapter for 12V?

So now you know you can get 12V DC from 5V DC but as you increased the voltage, the output current must reduce to respect conservation principle. So in reality you can extract very limited amount of power from your converter.
