How To Plug 12v Into 110v

To properly use the energy from the wall socket, the majority of electronic gadgets require some kind of conversion, whether it’s a straightforward voltage decrease, an AC to DC converter, or both.

While a simple voltage converter can convert a 110-volt power source to a 12-volt power source, if you’re also shifting from AC and DC power, you’ll require more than a simple gadget like this. If you already have little skill with electronics, you could build one yourself, but it’s far more effective (and yet reasonably priced) to purchase one of the many ready-built converters developed just for the job.

AC vs DC Circuits

An essential component of comprehending the difficulty of switching 110 V AC to 12 V DC is knowing the distinction between AC and DC circuits. Short for dc supply and long for ac power, the majority of equipment accepts DC input even if your house receives power in AC form. Due to their widespread use, AC-to-DC converters are actually built into the majority of gadgets, including your laptop.

Direct current travels in one direction while being driven by a constant voltage, making it considerably simpler to comprehend. This kind of steady energy, for instance, is produced by batteries (aside from a reduction in voltage as the battery drains).

But on the other side, alternating current changes in direction while the voltage that drives it oscillates in a sinusoidal waveform through positive and negative values. Because AC is simpler to transfer over large distances, it is utilized for power supply in homes and offices.

Transformers for Voltage

The energy supply’s voltage effectively informs you of the amount of “push” it needs to get the current flowing. If linked to an identical circuit, a greater voltage can generate more current (or anything with the same resistance). Nevertheless, if the voltage you’re utilizing as a power source is higher than the capacity of the object you’re powering, it might hurt the object.

Since they can change voltages between higher to lower levels or vice versa, transformers are utilized in this situation. A transformer is made up of two wire coils one connecting to the power source and the other leading to an instrument, both coiled around in an iron “core.”

With the assistance of the core, the energy from the first coil generates a magnetic field, and this magnetism generates a current in the second coil. The variations in the number of many wraps over each core are what affect how much voltage is given to that output.

Figuring a 110 to 12 Volt Converter

Simply purchase a converter made for the task from an electronic store and online, both of which will offer a wide selection, to transform 110 V AC to 12 V DC. The best recommendation is to identify the input voltage and current of the item you want to power, then purchase a converter whose outputs current and voltage match those figures.

You now understand that this needs to be a 12-V power source, so make sure to check that it is, but also ensure that you double-check the current. Additionally, if you’re searching for a 110-to-12-volt converter, be sure the device can receive the proper voltage from the power outlet, which will be 110 V (listed as the input).

Finally, make sure the polarity is correct on the adapter and the gadget you are charging. Three rings are typically used to represent polarities, with the middle circle containing an inner (mono color) core and an outside (non-circular) curve.

In the outside rings, there seem to be positive and negative signs that are attached to the inner core or the outside curve of the central sign. The positive sign has a positive electrical charge if it is located on the right (and links to the center core), and the negative sign does have a negative polarity if it does the same.

The converter will function as long as you confirm that the polarity, power, and ampere on the adapter and the gadget match, and that the adapter can receive the power level from the outlet. You can start using the devices after connecting them.

Converting 12 Volts To 110 Volts

You can follow these easy steps to learn how to plug 12v into 110v:

Step 1

Find out the product’s wattage, or how much power it consumes. A device’s wattage is frequently displayed on a label attached to the item or in the owner’s handbook. For several devices, sum together all the wattages.

Step 2 

Buy a voltage inverter that can deliver the required amount of watts.

Inverters come in a variety of varieties. Units that connect to a car cigarette lighter are accessible if the power needs are 100 watts or less. Bigger capacity inverters are possible, but they need to be directly attached to your battery.

Step 3

Confirm that the inverter and any connected devices can be powered by your DC power supply.

One amp of DC must be supplied for every 10 watts of electricity consumed as a general rule. Make sure your batteries are capable of supplying this amount of current and also that the fuse or breakers are the right sizes.

Batteries are graded according to their amperage or rated current capacity. The battery supplier will offer this standard. To boost accessible energy, several batteries may be linked in parallel. Wire the positive connections of two batteries together, then do the same with the negative connections to link the cells in parallel.

Step 4

Attach the DC source to the voltage inverter. This may be accomplished by simply attaching the gadget to one or more 12-volt batteries.

Use voltage level connections suited for the sort of batteries you have when connecting to them. At the end of the DC input cables for the power inverter, utilize the wire stripper to reveal one inch of bare copper. Making sure not to mix up the positive and negative connectors, plug each wire into the appropriate battery terminal.

Frequently Asked Questions

Can I Make 12v Work On 110v?

Whereas a basic power inverter can transform a 110-volt power source into a 12-volt power supply, if you’re also changing between AC and DC power, you’ll require more than a basic gadget such as this.

Is A Wall Outlet 12v?

A 12-volt outlet would be any electric socket that produces 12 volts and can be used to relate to: The most well-known example is a cigar light container.


By the use of a power inverter, 12-volt battery-powered electrical systems may be utilized to supply 110-volt AC. These gadgets may generate standard household electricity from several 12-volt DC (direct current) inputs, such as the cigarette lighter in your car. Volt inverters are employed in backup storage for pcs and other electrical devices when paired with a bank of batteries.

It’s important to exercise caution while employing voltage inverters so as not to exceed the limit of the 12-volt circuit delivering the electricity.
