Author: Rey Rowe  |  Last update: Saturday, November 20, 2021

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. ... Those pedals will work perfectly fine with a 12V adapter.

## What happens if you use a 12V on a 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.

## What happens if you plug a 12V into a 6V?

If the device has its own internal switching regulator, the voltage probably won't be a problem, but since the 12V power supply has a lower maximum power (12V * 0.35A = 4.2W, and 6V * 1A = 6W), it may draw too much power and the power supply will be damaged.

## 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 power supply on a 10v?

No it's not safe for the most of cases. There are two reasons. Since newer adapter has more terminal voltage therefore device is liable to draw more current and bad thing is that newer adapter is ready to provide more current. That's why things will get worse.

## How do you convert 12V to 9V?

To reduce a 12V circuit to 9V, place two resistors in series within the circuit. Find the difference between the two voltages (12V - 9V = 3V) to determine the total amount of resistance needed.

## Can I use 12V ups for 9V router?

However, the 9 Volt router cannot be run on the 12 Volt UPS. The 9 Volt router is meant to be run on 9 Volts and attempting to power it with the 12 Volt UPS will result in an overvoltage thus permanently damaging the router. No, it will not be possible to do that.

## Can I use 8v adapter for 9V?

If the old supply put out 8 V and 2.6 A and the equipment says it wants 8 V, then the obvious answer is a power supply that puts out 8 V and 2.6 or more amps. The equipment might be OK with 9 V, or not.

## Can I use 5V adapter for 9V?

The 5V supply and 9V need are close enough that it may work, for a while. In technical terms, a lower voltage can cause transistors to not turn on all the way, which produces waste, which produces heat that can burn them out.

## Are all 9V DC adapters the same?

– 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. Those are some very beefy supplies by the way!

## Can I use 500mA instead of 300mA?

What happens if I use a 9V DC/500mA power adapter for a guitar pedal that requires 9V DC/300mA? - Quora. Assuming the polarities are the same (center negative most likely), it will work just fine. The pedal's mA requirements are a minimum, and the power adapter needs to provide at least that much current.

## Will 12 volt LED lights work on 6 volts?

yes 12v LEDs will be much dimmer or possibly wont wont work at all if ran on 6v. Too dim to safely use as tail light.

## Can you run a 6 volt motor with a 12 volt battery?

A 12v battery is a 12 volt battery, you can't use it at 6v. It doesn't work that way. Each of the 3 cells in a 6v battery produces a bit over 2 volts, just like each of the 6 cells in a 12v battery produces a bit over 2 volts.

## Can you power a 9V pedal with 18V?

Generally you can safely plug an 18v pedal with 9 or 12 V but there is a good chance that it will work poorly... (although it might give an interesting distortion effect). If an 18V ped has digital save data, better not chance it. You may corrupt your sweet patch or loop.

## What happens if you use a higher voltage power supply?

If the current is the same but the voltage is too high, the device will shut itself off. It can run hotter than normal if it doesn't, which can shorten the life of the device or cause immediate damage.

## What does DC 9V mean?

it changes the Alternating Current from your wall into 9 Volts of Direct Current.

## What happens if I use a 5V adapter for 9V device?

Voltage too high – If the adapter has a higher voltage, but the current is the same, then the device will likely shut itself off when it detects an overvoltage. The device could power on and draw more current from the adapter than it's designed for. This could cause the adapter to overheat or fail.

## Can I use a 12V power supply on a 5V device?

The device will very likely burn out. In addition, depending on what the device is and the capacity of the 12V supply, connecting a 12V supply to a device rated 5V max could lead to a hazard - fire, explosion, etc.

## Can I use any 9V adapter for guitar pedal?

If you already have a 9V adapter and buy another pedal, the good news is that you don't need to buy another 9V adapter. It's possible to use the same adapter to power both pedals. ... Daisy chaining is as simple as buying a connector lead that allows you to plug multiple guitar pedals into your 9V power supply.

## Can I use 12V adapter for 24v?

Connecting AC adapters in series increases the voltage. ... By connecting two 12V adapters, you can achieve the 24 volts of current you need without the extra cost. You will be connecting the two adapters in series, which combines the voltage of the two adapters into the total of both without increasing the amperage.

## Can I use 7.5 V for 9V?

The long term effect of using 9 V instead of 7.5 V is unpredictable. It depends on the construction of the baby monitor's electronics. It may work or fail... Chances are that the 9 V adapter outputs a bit less than 9 V.

## Can I use 4.5 V instead of 5v?

They're very stable on the output voltage and can kick out an amp or so. It'll work fine.

## What does 12V 1A mean?

Output: 12V 1A means this equipment can handle ( consume or generate) 12Watts of power. And similarly. Output: 12V 2A means this equipment can handle ( consume or generate) 24Watts of power.

## Can I connect router to 12V battery?

Yes, it is safe as long as you don't short out the battery. The battery's voltage is not an issue, as almost all routers contain an internal regulator, especially when they do not use a lower voltage power supply. However, a better solution would be to get a 12V 1A switching wall adapter with the right connector.

## Can I use 12V 2A for 12V 1.5 A?

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.
