Can I use a 12V power supply on a 7v
1 Answer. 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.
Can you use 9v adapter for 7.5 v
However if the device is relying on the regulated voltage from the adaptor and has no internal circuit to control or limit overvoltage, then that 9v adapter may damage your device. That said, there are 7.5v devices designed with tolerances wide enough that the 9v you provide it won't make any difference at all.
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 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.
What happens if I use a 12V adapter on a 5V device
You cannot use a 12V power supply on a 5V. It will cause the device to draw more current than it is designed for and will likely burn out, causing fire hazards and explosions. In other words, if the applied voltage is more than the maximum rated voltage then the device will undoubtedly fail due to overvoltage.
Is it OK to use 12V adapter for 9V
Using a higher-rated power supply on a device is hazardous. It can damage the functionality of the device in a blink. It is never suggested to do so. Thus a 12V power supply is not compatible with a 9V.
Can I use 12V power supply for 8v device
As 12V is much greater than the required one, it's never suggested. The current rating is not the primary concern here if the voltage doesn't match. In this case, the device can be burnt or damaged due to overvoltage following overheating.
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.
Is it OK to use 12V adapter for 9V router
It might work depending on whether there's sufficient additional voltage regulation inside your router. But the adapter you're considering using puts out a higher voltage than the original, 12v versus 9v, and stands a good chance of burning up your router with higher current than intended. (Ohm's law says I = E/R.
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.
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 use 12V for 5V
You cannot use a 12V power supply on a 5V. It will cause the device to draw more current than it is designed for and will likely burn out, causing fire hazards and explosions. In other words, if the applied voltage is more than the maximum rated voltage then the device will undoubtedly fail due to overvoltage.
What happens if I use a 12V adapter on a 5v device
You cannot use a 12V power supply on a 5V. It will cause the device to draw more current than it is designed for and will likely burn out, causing fire hazards and explosions. In other words, if the applied voltage is more than the maximum rated voltage then the device will undoubtedly fail due to overvoltage.
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 run a 12V device on 9V
In most cases, a lower voltage adaptor might be plugged in without harming the device. However, if the polarity is switched, it will probably harm the device and blow a fuse.
Can you use a 12V adapter for a 5V device
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 charge 5V with 12V
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 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 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.
