Will a 12v motor run on 9v?

Can I power a 12V fan with 9V?

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.

What happens if I use a 9V adapter on a 12V device?

Plugging in an adapter with a lower voltage would not generally harm the unit. But if the polarity is reversed then it probably would cause damage and that may be what has happened. It may just have blown a fuse.

How long will a 9V battery power a fan?

An alkaline 9V battery has a capacity of about 560 milliamp-hours. A fan drawing 50 milliamps will therefore run for some 11 hours.

What can I power with a 9V battery?

A nine-volt battery, either disposable or rechargeable, is usually used in smoke alarms, smoke detectors, walkie-talkies, transistor radios, test and instrumentation devices, medical batteries, LCD displays, and other small portable appliances.

Can I use 5v adapter for 9V?

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 9V adapter for 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.

How long will a 12 volt battery run a fan?

A typical 12v RV fan will draw between 400-500 ma. So you can plug it into a cig type outlet, most 12v RV fans already come with that type plug. If you use the upper 500ma (1/2 amp) draw for your calculation, the fan will use 1 AH (amp hour) of power every 2 hours.

Can a 9v battery power a computer fan?

Circulating air is easily done by using an electric fan. … You can use electronic components, such as a computer fan, and wire it to work with a 9-volt battery. To do this you will need a fan and battery that have the same current and voltage.

How many volts does it take to run a computer fan?

5 Volts is necessary for the chassis and CPU fan or USB ports. 3.3 Volts is used to power the CPU.
