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

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.

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.

Can I use a 5V adapter to a 12V object and work?

A 5V adaptor cannot drive a 12V device. Also, an adaptor of voltage higher than the device needed would damage your device.

Can I use a 10v adapter for 12V?

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.

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!

Is it OK to use higher voltage adapter?

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. If it doesn’t, it may run hotter than normal, which can shorten the device’s life or cause immediate damage. This could cause the adapter to overheat or fail.

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 6v adapter for 12V?

– 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 a 9V adapter for 5V?

A 9v to 5v voltage regulator can be implemented with an LM7805 step-down voltage converter. It is used for (10mA to 1 Amp and more) medium to the high current application. The unique about this circuit is its ability to provide the same output current as applied at the input end.

Can I use a 9V power supply on a 5V?

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.

Can You charge a 12 volt battery with a 9 volt?

For example a car battery is 12 Volts but to be considered full it would have to show aboujt 13.5 Volts if you would check with a Volt meter. If you take a AA or AAA battery that is new, it will show you about 1.6 Volts or even more. The short answer is you can not charge a 12 Volt Battery with a 9 Volt battery.

Can you use a 6v AC adapter with a 9V adapter?

If you are talking about an ac adapter, then using a 9V or 12V adapter where 5V is required is not a good idea. 6V is only 20% off. I would not chance it but it might work.

Is the voltage of a 5v adaptor regulated?

Not necessarily. Most wall adaptors are not regulated, this means that the voltage they produce varies with load. For a “5V” adaptor with minimal load the voltage may be as high as 12 or 15 V. For this reason, most equipment designed to run off cheap wall adaptors contain internal voltage regulators to protect the sensitive electronics.

What happens if the voltage on an adapter is too low?

Voltage too low – If the voltage on an adapter is lower than the device, but the current is the same, then the device may work, albeit erratically. If we think back to our analogy of voltage being water pressure, it would mean that the device has “low blood pressure.”
