If you want to power it off of a 12V supply then what you do depends on if its AC or DC. For a DC power supply: You need to step the voltage down to 4.5V presuming the AA are in series. Make sure your 12V supply is DC. To do that I''d recommend a step-down DC-DC converter, just make sure it works within the voltage range needed.
Are Batteries AC or DC? The Ultimate Explanation
Part 5. How do batteries convert AC power to DC power during charging? An AC-to-DC converter is used when charging a battery from an AC source, such as a wall outlet. This device transforms the alternating current from the outlet into a direct current suitable for charging the battery. The process involves several steps:
Can You Use A Battery Charger As A Power Supply? Differences
Battery chargers are designed to convert electrical energy into a form that can safely charge batteries. They often include components to monitor the charge levels and control the charging process. In contrast, power supplies provide a steady output voltage and current to power devices directly and do not have the same monitoring functionalities.

This converter puts out 12.1V DC.
Wondering if i could use a 12v battery charger as my power supply
My portable air compressor has a dedicated 12VDC output with an inline 10A fuse used to power 12VDC devices however the manual explicitly states that you should not use either the air compressor or the 12VDC power output while recharging the self contained power supply (battery). So while I could use my portable air compressor as a power source
DC Power Sources and Batteries
This symbol indicates a generic DC power supply. It could be a battery, it could be a power supply ''box'' that is plug into a wall outlet to convert AC power of a higher voltage into DC power
How to convert battery operated lights to use electricity?
Get a power only usb cable - or cut an old cable up - and just wire them plus and minus from the cable to the battery wires. That gives 5 volts instead of 4.5, but it will likely be okay. Perfect way. Do the same thing. Measure the current with fresh batteries, then add a resistor in line with the 5v to get the same current as the batteries.
Feed a "solar" charge controller from AC->DC power supply?
In considering a DIY UPS-ish system (small bank of AGM batteries and an inverter), I knew I wanted/needed a charge controller, but most I found were just intended for keeping e.g. car batteries topped off. It has since occurred to me that "solar" charge controllers, of which small 10-30 amp versions are in abundance, run off DC input anyway.
Power a Cell/mobile Phone With External
For the S4 I used a laptop power supply with a 19 volt DC output at 3.5 amps and figured that if it is able to power a laptop with the battery removed it should be able to handle the phone easily.
How do i power a phone without a battery direct with a dc power
Basically you can get an adjustable buck converter that takes input from your dc supply and outputs an adjustable voltage. The input and output voltages will have a range of voltages
how to convert AC device to run on Battery? | All About Circuits
What is important is what comes out of that power supply, I.e., 9V. To run it off a battery, you would not use the AC adapter. You would connect your DC 9V source to a plug identical to the one coming out of the adapter and plug that into the power jack on the tablet. A small 9V battery is not sufficient. Your best bet would be a lithium battery.
Power a Cell/mobile Phone With External
I have also realized that any DC power source like a car, motor cycle, UPS or alarm battery, or DC power supply within the input range of the LM2596S module can be used to power a phone
Can you run a PC off DC power? : r/PcBuildHelp
The 120VAC at the input of a typical PC power supply is immediately rectified into DC. Rectified 120VAC gives you 120 x 1.414 = 170VDC. Inputting 170VDC into a PC power supply would simply get out of the rectifier stage with 170VDC, which is what the power supply in running on. Some of those Power Supply also run on 240VAC.

6 FAQs about [Is it okay to use DC battery to convert mobile power supply]
What happens if you replace a battery with a DC power supply?
If I replace my batteries with a power supply of equal voltage, then the current in the system also stays the same. This project uses this relationship to replace Voltage, V supplied by a battery with voltage supplied by a DC power supply – nothing else is changed.
Can I use a DC power supply instead of a battery?
This toy just sits on the desk, so it’s a good candidate to modify to accept a DC power supply instead of batteries. This idea is not well suited to something like an R.C. Car, but in a pinch, you can use it on the remote control for your TV. Wall outlet power is generally alternating current, or ‘AC’.
Do batteries use AC to DC power?
Batteries are direct current ‘DC’ and only push the current in one direction. An AC to DC power supply can change AC wall power to DC power. Many common devices that have batteries (laptops, smart phones, etc) only accept DC power. They use a AC to DC power supply to allow us to charge the device by plugging it into the wall.
Can I Power my Phone directly from a low voltage supply?
As for powering the phone direct from a low voltage supply you may be able to as long as its a regulated/switching power supply, which most are nowdays. Any voltage between 3.0 and 4.2 should work. Typically you want to aim for 3.6/3.7 though to give you a bit of wiggle room. However that's a bit of a wierd voltage for power adapters.
Can a battery charger be used as a power supply?
A battery charger is effectively a power supply. As long as the battery charger can provide the sufficient amount of voltage and current to the electrical load, it can be used as a power supply. There are some differences and considerations to take into account when using a battery charger as a power supply which shall be discussed in this article.
Should you replace batteries with a power supply?
Check the polarity of your batteries and power supply to ensure they match. There will be more on this in a later step. Before replacing batteries with a power supply, consider where the device or toy is used. Will it be sitting on a desk or near the bathtub? Would your kids put it in the bathtub?
