The simple answer is, No. But I'll give you the long answer, too.
The power rating of most devices is the maximum power used under unusual circumstances. Most devices, unless it's something like a light bulb which is either on or off, don't use their max power 99% of the time.
If you protect the circuit with a 1.0 amp fuse you protect your power supply and device and you can safely see if it works.

∙ 14y agoThe protection a one (1) amp fuse provides to a device will not be present when a larger fuse is used.
Wiki User
∙ 13y agoMaybe. It depends if the device really draws 3 A. If all else is equal, it shouldn't hurt to give it a try. Monitor supply for excessive heat and device for rated performance.

Wiki User
∙ 11y agoNo, the charging units output should be higher that the device that is to be charged.
Wiki User
∙ 11y agoYes, there is more than enough capacity in the power supply. Just make sure that the voltages match.

Can you use 16v 4.5 amps for 16v 1.5 amps?
First, let me clarify the question: You want to use a 16V, 4.5 amp power supply to operate a device that uses 16V, 1.5 amps. That's not a problem, the larger power supply simply has the capacity of 4.5 amps, meaning that you can use anything UP TO 4.5 amps. On the other hand... if you want to try using a device that pulls 4.5 amps, using a 1.5 amp power supply... sorry, won't work out well. That would overheat the power supply and it would fail.
Can your 40 amp electric stove be use in your new apartment of 20 amp?
If the supply is a 20 amp supply it cannot supply a 40 amp stove, you need a bigger supply or a smaller stove.
Can you use a 3 amp adapter on 5 amp device?
NO
Can you use a 19v adapter on a 15v device?
In short: Yes. As long as the voltage is the same, it makes no difference if the rated current is higher on the supply than on the device you want to operate. If you would take a 1.5 amp adapter for a 2 amp device, you overload the adapter which results in shut down or failure.
Can you use a 12v 1200 ma power supply on a 12v 3 amp monitor?
No, you should not use a 12V 1200mA (1.2A) power supply on a 12V 3A monitor. The power supply needs to provide at least the same amount of current (or more) than the device it is powering. In this case, the 1.2A power supply would not be able to provide enough current for the 3A monitor, and it could potentially damage the power supply or not provide enough power for the monitor to function properly.
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.
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.
Is it okay to use a 12 volts 600 milliamp DC power supply with a device that says it needs 12 volts 1 amp?
No, 1 amp is 1000 milliamp your power supply will only deliver 600 milliamp or .6 of an amp.
Can I use a 16vac 4A power supply to power 16vac 1000ma tube amp?
Yes, 1000 ma equates to 1 amp. The 4 amp power supply will have more than enough capacity to operate any device drawing 1 amp.Just make sure that the voltages match. AC voltage of the power supply to AC voltage on the device. You can not cross voltages using a DC power supply to operate an AC device, or the other way around, an AC power supply to operate a DC powered device, even though the voltage values are the same.
Can I use 1.5 amp power supply to operate a 220 miliamp device?
yes, as long as the voltage is the same, the device will only take what it needs as far as amperage.
Will a 12v 1.5 amp device work with 12v 2.5 amp replacement power supply?
No. The amperage describes the total electrical energyeither produced or consumed. Voltage just describes the potential. If the power cable or power supply are only capable of 1 amp and the device consumes 2 amps... sorry, you don't have enough electrical energy available.
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.
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.
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.
What is the use of a power supply?
power supply is a device that supplies electric power to electrical load
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.
