As long as the source voltage power supplies capacity is larger than the device's demand then it can be used.

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.
How many amps does a router use?
That depends on your router. The current draw of a router (or any other electrical device) can be calculated by: Amps * Volts = Watts If you know any two, you can calculate the third. If (for example) the router draws 750 Watts, and you know that it plugs into 120 Volts, then you can plug into the formula Amps *120 Volts = 750 Wats OR Amps = 750 Watts/120 Volts OR Amps = 6.25 If you would like the answer in volts it would then be about: 120
Can you use a 12v dc 1a power supply on device that requires 12v dc 3200ma?
No, 3200 ma = 3.2 amps
60 amps is how many watts?
Amps are not directly convertible to horse power, which is a measure of power. Power is current times voltage. Therefore on a 240 v supply, 40 amps equals 9600 watts. One horse power is 746 watts.
Is it a problem to use an adaptor with an output of 4.74 amps and 19 volts when the Laptop's input is 3.42 amps and 19 volts?
No problem whatsoever. As long as Voltage is the same and the supply Amps is greater than the laptop's Amps, all will be well. The Voltage will be supplied no matter what your laptop needs, creating an overload if the supply is greater than the demand. The Amperage will vary automatically depending on your laptop's need. There would be a problem if you used a 19V 2A power supply.
Can you use a power supply with more amps and not fry the unit?
you will need to be allot more specific on what you are trying to do here. what is the difference in amps. what is the device Generally speaking it is good practice to only use the power supply that the device is rated for. the biggest issue you will have is this Power = voltage * current (simple version) if the power supply you had was 12v at 1 amps then you ca supply 12Watts of power if the power supply you had was 12v at 10 amps then you can supply 120Watts of power Just because you can supply 10 amps, and all you need is one, means your power supply is bigger than it needs to be. The device will draw what it is intended to draw. Just make sure the voltage matches.
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.

If 1.8 amps ac is being drawn from a 24 volt DC power supply what would the current draw be in DC amps?
A 24 volt DC power supply provides DC amps, not AC amps. You cannot draw 1.8 amps AC from a DC power supply, without some kind of inverter stage.That is the answer to the specific wording of the question. Now the answer to the question I think was originally intended...If 1.8 amps AC is being supplied to a 24 volt DC power supply, what would the current supplied by the power supply be?Power is volts times amps, so power supplied to the power supply is 120 VAC (assumed) times 1.8 amps, or 216 watts. If the power supply is 100% efficient, then the power input equals the power output, so use the some equation to take 216 watts and divide by 24 volts, and you get 9 amps.Keep in mind, this is ideal state, assuming 100% efficiency, and no real power supply will be that.
Can you use a 1000 MA powersupply for your 1.5 amp router?
No the power supply is too small.
How far can AC-DC converter output volts- amps can diverge from input device volts -amps in other words Is it safe to use a 30V 0.5a ac-dc converter with a 30v 0.83A printer?
It is okay sometimes to use a power supply that allows for more amps than your device. You have a good chance of burning up your converter because the printer wants more amps than the power supply can give.

You have a good chance of burning up your converter because the printer wants more amps than the power supply can give.
Can you use a 9V 850MA power supply on a unit requiring 9V 2100MA?
No. A device that requires 2100 ma or 2.1 amps can not receive enough amperage from a power supply that will only deliver 850 ma or .85 amps.
What voltage is the power supply for a quest 2wire gateway model 2700HG-D?
The 2wire 2700 and 2701 models both use a 5.1 volt power supply rated 2 or 2.2 amps

No, 3200 ma = 3.2 amps
How do you find the current draw of an electrical circuit if you do not know the voltage and wattage of the device?
Basically if you know the Voltage supply and the power used by an appliance then you use the formula for power which is Power = Volts x Amps. Rearrange so Amps (current) = Power / Volts If power was 2400 Watts and Volts was 240 the Current would be 2400 / 240 = 10 Amps
How many amps does a computer draw?
It depends entirely on your type of monitor and power supply, but you can figure on the average of 100 watts per amp (that's a generalization of course). If you have for instance, a 350 watt power supply, that means the power supply can put out 350 watts of power for the computer to use, but that's the low voltage components of the power supply. As an example, I have a CRT type of monitor that uses 2.5 amps but on my power supply, there isn't a rating tag, so I'd approximate it at 1 to 2 amps. People tend to confuse output watts as the draw of power from the AC voltage, but there are other variables that come into play. Yes, those variables are power supply efficiency, PFC but mostly follow ohms law.
