Can you use a 12 volt 5 amp power supply on a 12 volt 2 amp device?

Absolutely.
As long as the converter (or any power source) is rated at the same voltage, with more current than the device needs.
Sometimes, a device may have a higher initial current surge than it's operating current, keep this in mind. Some converters do a good job handling momentary surge, some don't.

∙ 17y agoIf the device is drawing 3 Amps of power and your converter only generates 2 Amps, something bad will happen, either the fuse will go, the winding of the transformer will overheat or the thermal protection will blow. If the device is rated at 3 Amps, use a 4 Amp or higher rated converter to avoid problems. If the converter is always running at maximum output, it will fail.
Wiki User
∙ 14y agoYes - the amperage rating on a power supply denotes the maximum output current that it can supply at the rated voltage. Drawing less than the rated amount of current (i.e. a 2 amp device with a 5 amp supply) will not damage the supply or the device being powered.
Wiki User
∙ 11y agoNo, it may power the device on, but only for a limited time. You are trying to draw five times more amps out of the power supply than what it was designed to operate at. If left connected to the five amp device smoke will soon appear and the power supply will probably burn open never to work again.
Wiki User
∙ 10y agoYou can, but it probably won't provide sufficient current to power the device.
While you have to match voltages from supply to device, the current spec on the power supply has to equal or exceed the current requirements on the device. The device should naturally use whatever current it needs, based on its load. However, if the power supply does not provider enough current, then the device may not function.
Wiki User
∙ 11y agoNo. If the device is designed to run on 5 amps, it won't run on 2 amps.
Wiki User
∙ 11y agoNo, the voltage of the power supply is not high enough to operate a 12 volt device.
Wiki User
∙ 11y agoYes, 1.5 amps is the same as 1500 mA. Connecting a 1000 mA device to this supply will work fineleaving 500 mA capacity left over as spare.
Wiki User
∙ 10y agoNo the power supply must be capable of supplying the full load current.

Can you reduce 12 volt 5 amp powers supply to power a 12 volt to 150 milliamp camera?
You don't need to reduce the power supply. A device will only draw as much as it needs. A power supply of 12 volts 5 amps is the same as 12 volts 5000 mA. So you see that the power supply has more that ample capacity to operate a 150 mA camera. The thing to watch for is that both supply and camera need the same type of voltage, be it AC or DC. You can not cross that up and use AC on a DC device or vice versa.
Is it okay to use a 5 volts amp DC power supply with a device that says it needs 5 volts 2 amp?
It looks like the crucial number was left out of the question, between the words "volt ... amp DC". If the device says it needs 5 volts at 2 amp, it will run safely on any DC power supply rated at 5 volts and (2 or more) amps.
Can you use a 12 volts 3 amp power supply on a 12 volt 500 milliamp device?
Your power supply can supply 1 A, but your device requires 2 A. So the power supply will be overloaded. So the simple answer is no.
Will a 12 dc volt 8 amp power supply run a 12DC volt 9 amp motor?
Yes but only up to a load torque of 8/9 of the rated torque.
Can we run a 110 volt 100 watt DC motor with 12 volt 5 amp power is the same so it should run?
Sorry, won't work. You need a 110 volt supply.
What does Volt-Amp mean?
A 'volt ampere' (not 'volt amp'!) is the unit for theapparent power of a load in an a.c. circuit. It is simply the product of the supply voltage and the load current.

How much power is produced by a circuit by a 9 amp 27 volt circuit?
Power equals the product of current and voltage. The power used by a 9 amp 27 volt circuit is 243 watts. The power produced by the device, however, depends on the device's efficiency.
What will be the effects of using a 12V 1.5A power source to a 15V 1A device?
Most likely, yes. If your device requires 12 volt and draws 1 Amp of current, a 12 volt power supply will give the required voltage and will be able to supply the 1 amp of current it needs to run. A power supply that supplies a little more voltage might also work but depending on the device may cause the device to fail sooner. Much more than 12 volts will most likely destroy the device and result in a burning smell and smoke. A power supply for less than 12 volts may fail to power the device or may make it run slower. This would be like using a battery in a device and as the battery gets weaker, it supplies less voltage and the device slows down or a flashlight get dimmer till it stops working. A 1.5 amp power source is capable of delivering 1.5 amp of current to the device. If the device need less (only 1 amp), it still gets the amount it needs to function. If the power supply was rated at 10 A or 100 A, the device will still only use 1 A to function. If the power supply were rated at less than 1 amp. The device might not get enough current to run.
Can you replace a 7 amp 125 volt power cord with a 3 amp 125 volt power cord?
If the device you are powering requires 7 amps of power, then no. You will need to find a replacement cord with 7 amps. Check the power input requirements of the device to find out.
Is it okay to use a 5 volts amp DC power supply with a device that says it needs 5 volts 2 amp?
It looks like the crucial number was left out of the question, between the words "volt ... amp DC". If the device says it needs 5 volts at 2 amp, it will run safely on any DC power supply rated at 5 volts and (2 or more) amps.

Your power supply can supply 1 A, but your device requires 2 A. So the power supply will be overloaded. So the simple answer is no.
Will a 12 dc volt 8 amp power supply run a 12DC volt 9 amp motor?
Yes but only up to a load torque of 8/9 of the rated torque.
Can you use 5 volts 1.2 amp power supply on 5 volts 3.0 amp device?
No you can not. The power supply output of 1.2 amps is under sized. You would need to have a power supply of 3 amps or larger.
How many amps does a 220 ac use?
There is no standard Amperage for a 220 volt outlet. It all depends on the wires/conductors used to supply the outlet and the breaker that protects it. You can have an outlet with: 15 amp, 220 volt 20 amp, 220 volt And so on.....
Can you use a 9v-1a power supply when it calls for 9v-2000ma?
Unfortunately no, if the device calls for 2000ma you will need a 2A (amp) power supply to adequately power it.
Can a 12 volt 0.5 amp ac adapter substituted with a 7.5 volt 1 amp adapter?
No, it is not recommended to substitute a 12 volt 0.5 amp AC adapter with a 7.5 volt 1 amp adapter. The voltage and amperage ratings need to match the requirements of the device you are powering. Using a lower voltage adapter may not provide enough power, and using a higher voltage adapter can potentially damage the device.
