You don't. For battery power you have to install its own separate and isolated system. <><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What else can I help you with?
How do you change over so you can plug a 120V RV plug into a 240V single-phase twist-lock receptacle?
Is the 220V plug 220V only or 110/220V? (The former will have 3 prongs and the former will have 4) If your case is the latter just use the ground, neutral, and one of the hots. This will give you 120V single phase. If the case is the former you can't get 110V off that plug.
How can you plug 2000 watts 240v into a 120v 20 amp breaker with out replacing your breaker and all the plugs on the line?
You cannot safely plug a 2000 watt 240v appliance into a 120v 20 amp breaker without risking damage or fire hazard. To use the appliance, consider installing a step-up transformer to convert the voltage from 120v to 240v before plugging it in. This will ensure the appliance operates correctly without overloading the circuit.
How can you plug in 120V appliances such as a TV and VCR to an old 240V air-conditioning outlet with one white one black and one grounding?
At the breaker box the black and white will be on a double-pole breaker (or maybe even two separate breakers). To convert to 110V attach the black to a single pole 15 amp breaker, the white to the neutral bus bar (like all the other whites in there) and the ground to the grounding bar (like the other grounds). Then replace the receptacle with a regular 15amp 110V.
If you have a 240V 22A welder which has a plug similar but smaller than a dryer plug can you use this in a 120V outlet?
No, a 240V 22A welder requires a 240V outlet for proper operation. Plugging it into a 120V outlet will not provide enough power and could damage the welder or create a safety hazard. It is important to always use the correct voltage and amperage for electrical appliances.
Can you convert an existing 120V plug on an appliance to a 240V plug not speaking of a converter but actually changing the plug so there are no long term effects on the appliance?
If I understand your question, Can you run a 110 appliance off of a 220 volt outlet? You could by only using one leg of the 220. You may also consider changing the outlet. Put in a regular 110 outlet and capping off one leg of the 220 in the wall box. You still have a neutral and a ground to work with. I read this as the questioner doesn't want to modify the outlet. Check the voltage ratings on the device. Many electronic devices nowadays can havdle 120V or 240V as it is cheaper to manufacture one powersupply and sell it everywhere. If your device is rated for 240V, you can put a 240V plug on it. If it only says 120V, no dice. 240V will burn it up.
Can you use a 120V Dewalt battery charger rated 120V 60Hz off of a step down transformer putting out 120V 50Hz?
It will charge the battery a few times, but eventually it will ruin the battery. The problem is the difference in the Hz. The charger is designed to convert power at a specific level to DC power. When the input power is not at the needed pulse rate, in this case 60 Hz, it will not emit the correct DC voltage and slowly reduce the batteries capacity to hold a charge. If you want to continue using the 60 Hz charger, you need to convert the 50 Hz power into 60 Hz by filtering it through a battery. Example: Step down transformer 50 Hz 120v --> Battery supply (Uninterruptable Power Supply that can handle 50 ~ 60 Hz) --> Dewalt 60 Hz battery charger.... Or you can skip the science project and buy a 50Hz Dewalt battery charger. You may need a plug converter depending on the type of outlet you are using and the plug type the charger will come with.
What is the best battery pack for a 120v plug that you would recommend for portable devices?
The best battery pack for a 120v plug that I recommend for portable devices is the Anker Powerhouse 200. It is a high-capacity portable power station that can charge multiple devices simultaneously and is suitable for various electronic devices.
What type of power cord is required for a device that operates on 120V AC power?
The device that operates on 120V AC power requires a power cord with a standard 3-prong plug.
What device will give you time to save your document if there is a power outage?
A UPS (uninterruptible power supply) contains a battery, and an inverter (a device to convert the battery power to AC line current, for running devices that plug into the wall). Or a laptop with a working battery.
Introduction of DC to ac inverter?
A DC to AC inverter takes a DC voltage input to a AC voltage output. So if you have a 12v battery and need to run a 120v AC tool or something. All you need to do is plug a inverter to your battery and plug your 120v tool the the inverter. Takes all there is too it.
Do the power mat chargers plug in?
Yes they plug into a 110v wall plug, they do not need to plug into the phones if you have the battery doors, if you do not have the battery doors you need to plug the "power cube" into the phone witch has a 5" cord
Does the n64 have a battery?
No it has a plug and an power supply
Have Motor designed to run on a 12V battery and want to be able to plug it into a 120V outlet How can you do that?
You can't. At least not directly. You need to pick up a 12 volt power supply. Try Radio Shack, or just GOOGLE it.
How do you change over so you can plug a 120V RV plug into a 240V single-phase twist-lock receptacle?
Is the 220V plug 220V only or 110/220V? (The former will have 3 prongs and the former will have 4) If your case is the latter just use the ground, neutral, and one of the hots. This will give you 120V single phase. If the case is the former you can't get 110V off that plug.
You have 120v photo flash lights - how do you use them with 240v in Oz?
Power adaptors are readily available that plug into Australia's 240v outlets, converting to 120v. Find them in travel, luggage and electronics stores.
How can a desktop PC be operated in a rural area with a car battery as the source of power supply?
The only problem is that you need to convert the power? If so, the answer is an inverter. What this will do is convert the 12v DC power from the car battery to 120V AC (standard household power plug). They can be purchased at almost any auto parts or electronics stores. For a full desktop computer with a CRT Monitor you will probably need at least an 800 Watt inverter, but since the power ratings on most electronics aren't always truthful (or just use different ways of determining it) be prepared to buy a 1000W. http://www.radioshack.com/product/index.jsp?productId=2484365&cp=&sr=1&origkw=inverter&kw=inverter&parentPage=search Many car-part stores sell inverters. You plug one end into a car's cigarette lighter, and on the other end the device presents a normal wall-socket, into which you can plug your desktop PC and its monitor. Other types of inverters are supposed to be wired to a car-battery directly. An inverter converts a car's dc-12V power into the ac-120V that household wall-sockets have.
Is there a battery pack that a wall plug can plug into to have power?
Yes, but the power is limited. Normally used only for lighting when main power is out
