Can a 4.5 volt ac adapter be substituted for a 5 volt ac adapter?

Generally speaking the specified voltage is for the rated current so if used at a lower current a higher voltage will be present at the output. You can expect up to a 20% drop in voltage when loaded. So.. a 4.5 volt source rated at an amp could very well still be putting out more then five volts loaded to a few hundred milliamps. More important to consider is when you are using a high current adapter for a low current device you may be burning it up even though the voltage seams to match.
Finally your device should have a voltage range in which it operates, +10,-20% is typical.
This response is for an AC adapter, DC is a little deeper since there are battery eliminators and battery chargers, and of course with both Transformers get warm but smoke and fire is just wrong.

on a certain input voltage, and you're going to run it at 100% overvoltage.

What AC actually means in AC adapter?
Alternating Current ... like in most households.The adapter is either converting DC to AC or vice versa.
Why can't AC be measured by a Volt Ohm Meter?
Typical VOMs can measure both AC and DC.
Is a 360 watt 86 volt halogen light ac or DC?
A halogen bulb works equally well with AC or DC.
Can you use a 9v 300ma ac adapter in 9v 100ma socket its for a micro guitar amp?
yes but the device will not work property or nor work at all <<>> No, the 100 mA adapter will be too small to operate a device that requires 300 mA for its operation. By trying to draw a higher current than the adapter can supply, the adapter will heat up and possibly burn itself open. In other words the adapter will stop working.
How can I convert a DC adapter operated device into one that uses a battery?
A: A DC adapter is basically like a battery except it is conditioned from an AC source. To change over measure the voltage when fully operational then switch to battery that have the same voltage as the adapter. the only concern should be the power required
Can a 9 volt 100mA ac adapter be substituted for a 9 volt DC 300mA adapter?
No. an AC adapter will not work for equipment that needs DC.
Can a 9 volt 1600mA ac adapter be substituted for a 9 volt 300mA?
Yes, a 9 volt 1600 mA AC adapter can be substituted for a 9 volt 300 mA adapter. The mA number represents the highest allowable current to be drawn from the adaptor. The adaptor that you want to replace has only 300 mA maximum capacity. The new adaptor has five time the capacity of the old one which means that devices that draw up to 1600 mA can be connected to it. Depends on what you are pluging into.. if could possible run unit hot..
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.
Can a 4.5 volt ac adapter power a game that says to use 5 volt adapter?
No
Will a 120 volt AC to 12 volt AC adapter charge a 12 volt car battery?
No, the battery is DC not AC.
Will a 120 volt AC to 12 volt AC adapter charge a car battery?
No, auto batteries are DC not AC.
Can a 9 volt 1.3 A ac adapter be replaced with a 9 volt 1.6 A ac adapter?
Yes, this should work fine.AnswerThe rule is that the voltages should match, but the current rating of the adapter must exceed that of the load you intend connecting to it.
Can you run a 12 volt ac water pump with a 12 volt dc adapter?
No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.
Can you replace 12v vdc adapter by 12v vac adapter?
No, 12 volt AC is a different from 12 volt DC. Have a second look at the 12 AC volt adapter's output label. Most adapters contain a bridge rectifier in them that makes a conversion within the adapter. An example of this is in phone chargers.
Can you use a 19 volt 4.5 amp ac adapter to substitute a 19v 4.74 amp adapter?
Yes these voltages are close enough to be interchangeable.
Can I use 12V DC output universal ACDC adaptor with equipment that uses AC adapter 12VAC 2A?
There are many electronics today that run on 12 volt DC power. The good news for anyone who is traveling is that you can use a 12 volt AC adapter 12 VAC 2A.
Can I use a 9 Volt 1 Amp power adaptor in place of a 5 volt 1.2 Amp adaptor?
No, the voltage of the replacement adapter must always be IDENTICAL to the original adapter and the current of the replacement adapter must be the same or larger than the original adapter.Trying to use a 9 Volt adapter to replace a 5 Volt adapter will almost certainly completely destroy the device the moment you plug it in.You did not say whether the adapters provided AC or DC or the polarity if DC. Either way both the replacement adapter and the original adapter must be IDENTICAL in this respect.
