Short-Question

# Are 12V AC adapters interchangeable?

## Are 12V AC adapters interchangeable?

– 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.

What does mA mean on power adapter?

Glossary Term: mA. Definition. Milliampere, or milliamp: 1/1000 of an Ampere. Ampere is the basic unit for measuring electrical current.

### Can I use lower mA adapter?

NO you cannot do that. If the adapter is not able to supply the required current (mA), your product may not work correctly but more importantly, the adapter will overheat and may burn out. In the worst case it could cause a fire, so don’t do that.

Can you use any power adapter?

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.

#### 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’s the difference between 500mA and 600mA volts?

You’re going to feed it 4.5V with both devices, the difference between the 500mA and the 600mA is just the maximum amount of current the devices can deliver. So basically, a 600mA will be at least as good as a 500mA, since the new Volts require less current.

## What are the different names for power adapters?

Power adapters are known by many names: AC adaptor, AC/DC adaptor, AC/DC converter, or, a PSU or power supply unit.

Can a power adaptor with a lower current rating be used?

A n adaptor with a lower current rating than required may not be able to supply sufficient power for the pedal to operate as intended. But, as we now know, a pedal will only draw as much current as it needs, so any adaptor with a higher current rating than recommended is perfectly safe.

### What makes up the output of an AC adaptor?

Their electrical output is described by four things – the voltage they provide, the type of voltage (i.e. AC or DC), the maximum current the adaptor can supply, and when the output is a DC voltage the polarity of the voltage at the output plug.
