A charger needs to provide a controlled voltage higher than the battery voltage in order to charge it, and also needs to control charging current. Its voltage needs to change as charging progresses. A 12V power supply will provide a constant 12V, and may or may not have a current limit/control feature.

What is the difference between a charger and a power supply?
In short – a Power Supply is intended to provide a constant voltage to static applications, whereas a Charger is designed to provide a continuously regulated current to mobile devices, which have an integrated Battery.
Can a 12V power supply be used as a charger?
Yes, if the 12V supply can be cranked up to deliver 14.4V. If the power supply delivers 12.0V, the car battery will only get charged 40%.
Is a power supply a charger?
A battery charger is a type of power supply. After all, what is required is to convert the AC power to something suitable to charge a battery.
What does 12V power supply mean?
12V power supplies (or 12VDC power supplies) are one of the most common power supplies in use today.Linear regulated 12VDC power supplies regulate the output using a dissipative regulating circuit. They are extremely stable, have very low ripple, and have no switching frequencies to produce EMI.
What are the 3 types of power supply?
There are three subsets of regulated power supplies: linear, switched, and battery-based. Of the three basic regulated power supply designs, linear is the least complicated system, but switched and battery power have their advantages.
What is the difference between a battery charger and a transformer?
The most important difference between these two groups lies with the transformer. The transformer is needed to convert the current from the high network voltage to the low battery voltage.Battery chargers that have transformers with an iron core and copper windings are called traditional battery chargers.
Can a 12V charger overcharge a 12V battery?
A 12V lead-acid battery won’t be damaged by overcharging if the voltage is kept low and the charging current is less than the Ah capacity.
Can I use 12V charger for 12V battery?
no. Your charger is lower than your battery requirement and can’t charge it fully, so while it works a little, you’ve very little charge in the device to work for more than a few minutes. This is a safe outcome. And you’ll know soon enough that’s it’s of no use.
How much voltage is required to charge a 12V battery?
A: A 12V car battery can be safely charged over a range of voltages. It needs at least 12.9 volts to charge, but at this voltage the charge rate of an automobile battery is very slow. A car battery can be charged safely at high voltages as long as the battery is not fully charged.
Will a power supply overcharge a battery?
Yes if it is an unregulated adapter, generally the voltage will rise in excess of 15 volts as the current drops below it’s rated output.
Can I use a phone charger as a power supply?
Yes, USB connectors normally imply 5V, but note that (cheap) USB connected chargers (not “power supplies”) may be unregulated, and when lightly loaded may output more than 5Volt, even 6Volt or more.
Can an AC adapter be used as a charger?
Adapters can sometimes be used as a charger, but a charger will never give you the same energy output as an adapter will. When it comes to some electronic devices such as laptops, your charging cord and your adapter are pretty much the same thing. Adapters will provide electrical current to something such as a laptop.
What uses a 12V power supply?
The 12 Volt Adapter Power Supply is used in: Pads, Laptop computers, lighting, mobile equipment and many more. They are now finding their way into more consumer toys, games and other home goods.
Can I use 12V DC instead of 12V?
As long as the voltage of the “DC Appliance” is not less than the 12 Volt adapter then it will either work or won’t, all in all it’s a bad idea to experiment, actually it’s a bad idea just to even think about doing it, unless you know about what you are about to do, don’t.
What uses 12V plug?
The 12V socket, also known variously as a car cigarette lighter or 12V auxiliary power outlet, is the primary method by which power is delivered to portable electronics in cars, trucks, recreational vehicles, boats, and in a handful of other contexts.
Does it matter what power supply I get?
The more efficient your PSU, the less power it uses, and the less heat it generates. That said, higher efficiency usually means a higher price, so you’ll want to find the balance that works for you. Even the most efficient PSU will still generate heat, however, and most use fans to disperse that heat.
How do I choose the right power supply for my electronics?
Power Supply Voltage
If your device needs 9V, you need a 9V power supply. If your device needs 5V, you need a 5V supply. Also, if your device needs a DC voltage (which is the most common), you need a DC output from your power supply. If your device needs AC voltage, you need an AC output.
What are the 4 types of power supply?
There are three major kinds of power supplies: unregulated (also called brute force), linear regulated, and switching. The fourth type of power supply circuit called the ripple-regulated, is a hybrid between the “brute force” and “switching” designs, and merits a subsection to itself.
Can I use a battery charger as a transformer?
Yes you can but not with any transformer, there are specific transformer which come with multiple output voltage. Otherwise for normal transformer you need some ckt to lower the voltage. Keep in mind transformer only work in AC and tour battery is a DC component. So you will need a ckt to convert into DC.
What is the purpose of a transformer in an charger?
The purpose of a transformer is to convert one AC voltage to another AC voltage. In this case the transformer converts the normal 120 volt AC current in your house down to three volts. The 120 volts comes in on the primary winding on the left.
