Can I use 5V adapter for 12V
Most likely not. But as always it depends on what product you are trying to power up with the 5V instead of a 12V source. A fan may work but slow, a heater will work but at 17% power output, a peltier cooler/heater will work but will not remove as much heat.
Can I use a 5V 2a charger with a 5V 3a device
5 Answers. Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger.
Can I use 12V 2A for 5V 2A
No, You can use a 12V 2A Adapter with a higher current rating, but not one with a lower current rating. The device draws only the current it needs, but the power supply must be able to output the maximum current that the device requires.
Can I use a 12V power supply on a 5V LED
A 5V LED must not be run on 12V. But there are lots of options to convert 12V to 5V. As Jason Vaughan notes, a USB charger intended for a car will do a good job – unless you need a lot of power.
What happens if you use a 12V charger on a 5V battery
Can you power 5V with 12V The device will very likely burn out. In addition, depending on what the device is and the capacity of the 12V supply, connecting a 12V supply to a device rated 5V max could lead to a hazard – fire, explosion, etc. Device consists of components which are rated for a given voltage and current.
Can you use a 12V charger on a 5V battery
The technical answer is yes. But you need to limit the charge current somehow and make sure that it shuts off when the battery is full.
Can I use 12V 2A for Arduino
With a 12V source, yes, current should limited to avoid overheating/shutting down the regulator.

Can I plug 12V into 5V RGB
Without question the 2 versions of RGB are not interchangeable and do not work together. Plugging 5v circuit into 12v header may cause damage to the product you are plugging in. Notice a couple things.

Can a 5V motor run on 12V
You can not power a 5V motor with a 12V supply, unless you keep it submerged in liquid nitrogen to deal with the heat.

Is 12V OK for Arduino Uno
"The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts."
Is 12V too much for 5V
Long story short, you should avoid using a 12V power supply on a 5V device. Unless there is a protective measure in the device to tackle the resultant surge of current, it is best to avoid using a higher voltage than the maximum rated voltage.

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.
Can I use 12V on a 5V relay
More videos on YouTube
No, it is not recommended to use 12V on a 5V relay. A relay is a type of electrical switch operated by an electromagnet. Relays are commonly used to control the electrical components on a circuit.
Can I use 12V adapter for Arduino
You can use any 12V AC-DC adapter with proper out voltage and proper connector to power your Arduino board. It is more convenient when deploying your project where it's not constantly monitored. You can also use a 9V battery to power the Arduino Uno, with the help of a snap-in connector with a DC Barrel Jack.
