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 12V 1a adapter for a 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.
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.
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 12V adapter for 6V
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 on 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.
How to supply 12V to 5V
12v to 5v DC Converter InstructionsConfirm which wire on your DC power supply is POSITIVE, and which wire is NEGATIVE.Connect the DC converters Input RED wire to the POSITIVE wire of your DC power supply.Connect the DC converters Input BLACK wire to the NEGATIVE wire of your DC power supply.
Will too much amperage hurt a device
It will be perfectly safe. A device that only requires a certain amount of current will not draw more from the supply than it needs. Think of it this way: Voltage is pushed to the device from the power supply, so an excessive voltage can easily damage the device.
What will happen if I use a 5V 1A charger to charge a 5V 2A device
Using the 5V 1A charger to operate a device that is normally charged with a 5V 2A charger is a bad idea. The smaller rated 1A charger is likely to overheat when used in this manner. In the worst case it could even catch fire so don't do this.
Can I charge a 5V battery with a 12V charger
No, the charger needs to have an output a little higher than the battery you are trying to charge. If you use less, no charging will occur.
Can I use 12V adapter for 9V
You shouldn't. Many electrical gadgets have extremely delicate constructions that cannot withstand even a very little voltage that is higher than what is recommended. Such as most of the time, a 9V guitar pedal cannot be powered by a 12V adaptor.
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 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 wrong voltage
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.
Can 100 amps hurt you
The answer is very little. A current of as little as 0.007 amps (7mA) across the heart for three seconds is enough to kill. 0.1 amps (100mA) passing through the body will almost certainly be fatal.
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 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.
Will too much amperage hurt A device
It will be perfectly safe. A device that only requires a certain amount of current will not draw more from the supply than it needs. Think of it this way: Voltage is pushed to the device from the power supply, so an excessive voltage can easily damage the device.
Can I use 12V adapter for 7.5 V
You should never use a significantly higher voltage rating adaptor on any kind of electrical device. If you do so you are risking damaging the equipment and anything else that you might have plugged into it.
Will too much voltage hurt a device
Voltage that is too high can cause premature failure of electrical and electronic components (e.g. circuit boards) due to overheating. The damage caused by overheating is cumulative and irreversible.
Can a human survive 10,000 volts
Dr. Michael S. Morse, a professor of electrical engineering at the University of San Diego, explains that while 10,000 volts can be life threatening in certain circumstances, it's possible for something to have 10,000 volts behind it and be relatively harmless.
Is 1 amp harmful
Death is possible. 1.0 to 4.3 Amps Rhythmic pumping action of the heart ceases. Muscular contraction and nerve damage occur; death is likely. 10 Amps Cardiac arrest, severe burns, death is probable.
Can you use A 12V adapter for A 6V device
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.
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.
