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.

## Can I use 12V 3A for 12V 2a?

Yes, you can use. The voltage rating of the device should not decrease but for current it will work as it means the device need 1.5A current to work and our adapter is capable of providing till 3A current.

## Can you use different power adapter?

NO! Your output voltage is wrong, which is the important part. You can safely use an adapter with the same output voltage, and a current (A/mA) rating equal or higher than the original.

## Can you use any AC charger?

Use as close to, if not exactly the proper Voltage and Amprage needed by the device recomendations. Better a little over than under… 3. Ac voltage is important but usually AC devices only draw the amperage as neeeded so as long as there are sufficent amp supplied, the device should be ok.

## What is the difference between an AC adapter and a DC adapter?

An AC adapter converts alternating current from one voltage to another, while a DC adapter converts alternating current into direct current.

## Are all 12V adapters the same?

All you do is find a wall adapter with an output that matches the input of your device. There are so many different wall adapters that a list of them all would be impossible to maintain. Every new device that comes out usually has a custom one.

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.

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

• 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.

## Can I use 12V 2A for 12V 1A?

Yes You can 12 V 2A for 12 V 1A.

## Can I use 12V AC to power 12V DC?

If you are looking for an power supply to convert your 12V AC low voltage system to 12V DC, to power up your landscape lights or others 12V product, this 12VAC to 12VDC adapter is a good solution for your application.

## How do I know what size AC adapter I need?

If you go into a shop you can compare and test the connector size, or if you are technically minded you can measure the size of the port and pin yourself. If you are measuring you need the diameter of the center pin for the (ID) and the inner diameter of the port (OD).

## Are laptop AC adapters interchangeable?

Laptops can share power cords so long as the adapter’s wattage and connector tip is correct and compatible for each laptop you wish to use it with.

## What happens if I use a higher voltage adapter?

Higher current (A) is okay because the device won’t use as much, but higher voltage (V) is going to “fry” it. Conversely, lower voltage is unlikely to cause damage since the device simply won’t have enough power, but lower current can cause trouble because the power supply cannot provide enough.

## What happens if you use DC instead of AC?

What Happens when DC Devices Operated on AC? If we connect an AC supply to the DC devices and equipment: The positive and negative voltage will destroy (this is not always the case) some of electronic components such as transistors and electrolytic capacitors.

Other AC rated equipment with inductive components (such as transformers) may also be destroyed by high currents from DC and will again usually not operate. AC solenoids will usually operate on DC but will usually burn out rapidly or at some stage due to high currents.

## How do I replace my AC adapter?

Other AC rated equipment with inductive components (such as transformers) may also be destroyed by high currents from DC and will again usually not operate. AC solenoids will usually operate on DC but will usually burn out rapidly or at some stage due to high currents.
