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.
Can I use a 5V LED on 12V
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.
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 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 charger to charge 12V battery
No way it'll do 12V or any other chemistry. To charge any battery, you need to give it a voltage higher than what it's going to charge to.
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.
Can I charge 12V battery with 15v adapter
yes, but it will charge it slow due to low difference of voltage, generally we use such as for 3.7 volt battery 5 volt charger and for car 12 volt battery we use solar panel of 20 volt.
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 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 19.5 V charger for 12V device
19v chargers in general are considered too high for a 12v device. In most cases venturing beyond 14-15v is highly discouraged.
Can I use 16V charger for 12V battery
It is not recommended to charge a 12V battery with a 16V wall charger. Batteries have a specific voltage range in which they can be safely charged, and charging them outside of this range can damage the battery or even cause it to catch fire or explode.
Is 5V stronger than 12V
So the 5V system is 2.4 times more efficient than the 12V system, meaning you need to provide 2.4 times as much power as a 5V system to achieve the same outcome. Where is all this extra power used up in the 12V system you may ask Well, it is dissipated in the form of heat!
Can I use 5v charger to charge 12v battery
No way it'll do 12V or any other chemistry. To charge any battery, you need to give it a voltage higher than what it's going to charge to.
Can I use 5v charger for 12v battery
Never, To charge 12v battery you need 12v or higher charger.
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 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 6 volt charger on a 12 volt battery
On the first place, 6 V charger will not be able to push current through 12 V battery. Next, a trickle charger will just supply trickle current, enough to keep battery in charged position by feeding the current it loses by self discharge. This cannot charge a battery even if the voltage is 12 V.
What happens if I plug 19V into 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.
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.

What happens if you don’t match voltage
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, then it may run hotter than normal, which can shorten the life of the device or cause immediate damage.
