Can I use 9V adaptor for 12V
When not loaded, a 9V supply that is unregulated could provide you with up to 14V or somewhat higher if you need regulated (steady) 12V. There's a good chance that it will, but it's not certain. Just purchase a compatible new power supply. Although you can try, it's not suggested.
Is it OK to use higher voltage adapter
An AC adapter supplying electricity at a higher voltage than required will cause the connected device to run hotter. Sending power at a higher voltage will also shorten the lifespan of the device and may fry its internal circuits. Using an AC adapter with a different current rating can be an issue.
Can I use a 12V power supply on a 9V keyboard
Can you use a 12V power supply on a 9V device Not Recommended. Unless supply just barely supplies full load current and is a simple brute force transformer and two diodes. These drop a lot of voltage on load.
Can I use 24v adapter for 12V
Not likely. You always want the voltage to be as close as possible between the device and the power source. The current (amps) can be equal or greater than what the device accepts. I would not try to use a power adapter if it is more than 3–4 volts different than what the device is rated to accept.
Can you power 12V LED with 9v
A 9-volt battery can satisfy the requirements of a strip with a 12-volt rating, but only to an extent. Since a 9V battery generally has a lower power output, it won't provide enough juice to power your 12V strips at full performance. The result would be a lower brightness emission.
Can I use 18V adapter for 12V
18V would be risky, I would not try to plug a 12V device into an 18V battery. But if you happen to have 18V for whatever reason, you can always use a DC-DC converter.
What happens if I use a 5V adapter on a 12V device
That said, I'd suggest against using a 5 volt supply for a 12 volt device. For a start, if it really requires 2 volts (or close to it), you will have a problem because 12 x 2 = 24 watts, while 5 x 2 = 10 watts, so the power supply is under-specced to do the job at maximum load.

How to convert 12V adapter to 9V
Step Down the Voltage
Install the smaller resistor first, stepping down your voltage from 12V to 11V. Once you've added the first resistor to your circuit, install the larger resistor to step the voltage down again. This resistor will take the remaining 11V current and reduce it to the 9V output you desire.
What happens if I plug 24V into 12V
Charging from a 24 volt system to a 12 volt system
Using a split charge relay (VSR) would just send the alternator's 24V charging voltage to the 12V battery which would cause damage. Instead, you would need a 24 volt to 12 volt DC-DC charger.
What happens if I use a 12V adapter on a 9V router
If you use one with significantly more voltage (and 12v is a full third more than 9v) then you might burn out your device.
Can I power a 12V DC motor with a 9V battery
In principle, it's probably possible to run a 12V motor on 9V — it'll just run slower and with much less torque. But if by "a 9V battery" you mean a typical PP3 size battery (i.e, the rectangular ones with a snap connector on top), the answer is almost certainly "no".
Can I use 16V adapter for 12V
The 16v adapter would raise the voltage too high and could cause damage. A 4A maximum current would be fine and would not cause any damage, but you need a 13.8v source.
Can I use 5v adapter for 12V device
That said, I'd suggest against using a 5 volt supply for a 12 volt device. For a start, if it really requires 2 volts (or close to it), you will have a problem because 12 x 2 = 24 watts, while 5 x 2 = 10 watts, so the power supply is under-specced to do the job at maximum load.

Can I use a 6v adapter for 12V
The short version: Voltage (V) should always be the same for both adapter and device. Polarity (plus on the left side or plus on the right side) should always be the same for both adapter and device. Current (A or mA) of the adapter should not be lower than the current of the device but may be higher.
Can I use 12V adapter for 9.5 V
Is it safe to use an adapter that has higher voltage than what is required by the device being powered by it No. Using an adaptor with a higher voltage than the device being powered is risking damage to the device.
Can I use 19v for 12v
19v chargers in general are considered too high for a 12v device. In most cases venturing beyond 14-15v is highly discouraged. Although the appliances work for a while, they will very likely be damaged after that period has passed. It could be seconds, minutes, hours, days, or even months in some cases.
What is the maximum voltage for a 12v LED
between 10V and 12.8V
We've shown that for a 12V LED strip, it can go from dark to overdriven in a narrow range between 10V and 12.8V. While it is possible to supply a voltage that is slightly different from the rated voltage, you will have to be careful and precise to ensure that you do not cause any damage to the LEDs.

What happens if you plug a 12V into a 6V
It is never recommended to use a 12V power supply on 6V. This will deplete your battery and result in a severe thermal runaway situation. Some individuals use a 12V charger to jump-start their 6V battery, however, it is never a good idea to try to fully charge your 6V battery with a 12V charger as well.
What happens if you put a 12 volt charger on a 6 volt battery
This will run your battery dry and create a thermal runaway scenario, which is very dangerous. Again, some people use a 12V charger to get their 6V battery jump started, but it is never advisable to use a 12V charger to try to fully charge your 6V battery.
Can I use 12V 1a adapter for 12V 1.5 A device
Can you use a 12V 1a charger on a 12V 1.5 a device or 12v 2a device 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.
What happens if you plug 19v into 12V
