Can a 9 volt fan run on 12 volts?

Can a 9 volt fan run on 12 volts?

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.

Can I use 9V battery for 12V DC motor?

Yes, either in series or in parallel. Most 12v dc motors will rotate on only 9v. Putting two 9v batteries in parallel will increase the current and give you better result than two 9v batteries in series since motors like current more than voltage, i.e. they suck a lot of current when starting up.

Can you use a 9 volt adapter on 12 volt equipment?

It depends on whether your power supply is regulated. If you need regulated (stable) 12V, and the 9V supply is unregulated, it could give you up to 14V or slightly higher when not loaded.

Can you run a fan at lower voltage?

There is generally no harm in running a fan or any DC motor on lower voltage. If the voltage is too low, then the motor will not run (or continue running if already spinning but not start), because there is not enough torque generated to oppose the “cogging” effect of the layout of magnets inside the motor.

What happens if you plug a 9V into a 12V?

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.

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.

Can I use 9V adapter for 12V router?

You cannot use that adapter because it is outputting more voltage than the original (12v vs. 9v). This has a likely chance of burning out one or more of the components within the router. The output voltages must be identical.

How much voltage a fan takes?

Voltage, Current, and Wattage

Voltage Range: Higher voltage ratings above 100. Common Voltage Range: Lower voltage ratings below 100.
AC voltages include 110, 115, 120, 220, 230, 240 Common DC voltages include 3,5,12,24,48

How much power does a 120v fan use?

Typical ceiling fan current draw (amps) at 120V:

Fan speed or mode Power (W) Amps (A)
Off 0A 0A
Low 12 0.17A
Medium 42 0.58A
High 46.6 0.65A

Will any 9V adapter work?

any 9v with the correct polarity (- inside +on the outside i think) that supplies enough amperes (250 milliamperes minimumi think) will work fine. As long as the voltage matches up, 9v DC pedal with a 9v DC power supply, you will be fine.

What is the difference between 9V and 12V?

However, there is not much difference between 9V and 12V. It does not take much current to be drawn from the battery before it drops 2V at its terminals. A small mount of extra drop in the wiring and the internal 9V supply drops. After that, the available current from the controller drops quite quickly!

How long will a 12 volt battery run a fan?

Nominally, a 12 volt 100Ah battery has and energy capacity of 12 x 100 = 1200 Wh (watt hours). So nominally the fan would run for 1200/100 = 12 hours.

Is a 12V fan with a 1 amp power supply good?

Low amperage 12v fan + strong 12v power souce = good On the flip side, if you put a 12v @ 1 amp fan and the power source can only do 12v @ .40 amps it will cause problems. The fan will want more amperage than the power source can supply causing it to overheat (or other nasty issues).

Should I change the voltage or amperage of my fan?

Lower or same amperage can’t really hurt. More amperage could blow a fuse, fan controller, etc. Also keep in mind if this is a 12V brushless fan like PSUs usually use, or a PWM fan. Also check if the original has a stall output.

Why does a fan use more power when it is off?

The fan will be doing a certain amount of work in turning itself, and resisting the air it is pushing. If the fan is in free space, plenty of air is available for the fan to move, and it does more work. Therefore, it slows down, and uses more power.

How long will a 9v battery run a laptop?

It will probably run at about 3/4 the speed and draw about 3/4 the current (rough estimate) so around 100mA. Looking at a typical datasheetfor an alkaline 9V battery, we can see the capacity will be perhaps 350mAh (down to 4.8V) so it might work for 3-5 hours, as the current will drop as the battery discharges.
