To run a small 120 volt ac appliance from a car battery you need an an "inverter unit" which is generally how televisions, electric razors, etc. are run in motorhomes or boats.

Shops or online stores which specialize in parts for cars, caravans or boats generally sell inverter units in various sizes to handle increasing amounts of total output power (watts).

Note: If you are thinking of powering a high-powered unit such as a clothes dryer from a battery, remember that power = volts x amps. So a unit that draws 20 amps at 120 volts takes 2400 watts. Apart from the very high cost of an invertor unit capable of handling that amount of power, such an appliance would draw at least 200 amps from a 12 volt car battery. So, at best, a large 100 ampere-hour 12 volt battery would go flat in about half an hour!

What happens if you plug a 120V appliance into a 240V outlet?

You will burn up your appliance!!!!!


Can 120V appliance work with 220V?

120V appliance will not work on 220V. Use an instrument transformer or voltage regulator to adjust the high voltage to the desired level.

How can you convert US 120V or 240V circuit into a single phase 240V circuit to use on a European appliance?

The voltage isn't a problem, you can run 220 from your house and use that to run a European appliance, the problem is whether the appliance is dependant on line HZ. European is 50HZ and US is 60HZ. If the appliance specifies 220/50HZ, it will probably give you trouble here. If it says 220V/50 or 60HZ


Can you buy a 120v appliance and use it with a 220v outlet?

A high voltage will certainly damage a low voltage appliance and perhaps set fire to other things nearby.


Can a kitchen stove be on the small appliance circuit?

No, unless it's a gas range. An electric range requires 240V and 40A while a small appliance will be 120V and Max 15A.


Can a 9V battery power a 120V light bulb?

im not sure if this will work or not but... If you use a 9v battery threw an inverter, then a step-up transformer to convert 9v DC to 120v ac i think it will light the bulb, however current decreases when you do that and i dont know how much a light bulb needs..worth a try, i might actually try it now


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.


Can you plug in a 120v appliance into a socket in UK?

No, the cord ends have different configurations to prevent this sort of thing from happening.

You can buy a converter.


If you use a 120V appliance out of the US will you still be able to use it in the US after?

Of course, unless somehow you destroy it by plugging it into a voltage it can't handle.


Can you use UK appliances in the us?

Not unless the appliance is rated to be used with the two different power supplies. The US uses 120v, 60 Hz if it plugs into a receptacle, and possibly 240v, 60Hz if it is hard wired. The UK uses 240v, 50Hz whether it plugs in or is hard wired. These two power systems are NOT compatible. You may use a US appliance in the UK, and vice versa, only if the appliance is dual rated, i.e. the appliance says 120v/60Hz AND 240v/50Hz on the nameplate. If the appliance only specifies one power supply, it can only be used on that power supply. If this is the case, you may be able to use a travel adapter to operate the appliance.
