# Can I use any 9V adapter?

### Can I use any 9V adapter?

You can safely use an adapter with the same output voltage, and a current (A/mA) rating equal or higher than the original. If you use one with significantly more voltage (and 12v is a full third more than 9v) then you might burn out your device.Jan 28, 2013

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.Apr 30, 2010

### How do I know what size DC plug I need?

If you are measuring you need the diameter of the center pin for the (ID) and the inner diameter of the port (OD). ID an OD measurements for both the female and male connector must match to connect properly.Nov 30, 2020

### What is A DC 9V adapter?

The adaptor converts AC wall power to 9-volt DC for powering most instrument pedals and other 9-volt battery devices. The tip negative, sleeve positive power supply can handle 500mA to power even your most power hungry devices.

### What happens if I use a 12V adapter on a 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.

### Can you run a 9V motor on 12V?

The 9V batteries are weak because the other half of the story is how much current they can supply. … It’s possible to run a 12V motor on 9V, but it will run slower and with less Torque.

### 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.Dec 14, 2020

### Can I run a 9V fan on 12V?

Yes, you can do it, but the battery won’t last very long. It will probably run at about 3/4 the speed and draw about 3/4 the current (rough estimate) so around 100mA.Jul 1, 2018

### What is a DC adapter used for?

A power supply for electronic devices. Also called an “AC adapter” or “charger,” power adapters plug into a wall outlet and convert AC to a single DC voltage. Computers use multiple DC voltages, and the power adapter is the external part of the power supply for a laptop.

### 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.Jun 17, 2021

### What uses 9V power supply?

A lot of things use those small 9V batteries. Smoke detectors, some transistor radios (not so much any more), lots of handheld test equipment, electronic toys, etc. More and more things that in the past typically used 9V batteries are being designed to run from one to four AA or AAA cells.
