No, the battery is DC not AC.
No, auto batteries are DC not AC.
Yes, but you are limited to the amount of current draw the 120 volt load can apply to the adapter.
An adapter can be used. Make sure that the adapter that you use is of a capacity that it can produce the amperage that your appliance needs. An adapter too small will burn itself open and will be of no use to anyone. Remember; Watts = Amps x Volts.
There is no remedy but to plug it into a 230 circut.
Cars do not have 120 volt batteries. They are 12 volt DC.
Yes, this can be done. The adapter will handle at 120 volts x 15 amps = 1800 watts. The adapter is just a step up transformer. The maximum 220 volt device that can be connected can only have an amperage rating of 8 amps at 220 volts.
No! and you might have a nasty fire with sulphuric acid spilling everwhere. A battery pack is always DC and it must always be charged with DC. It must also have a device for limiting the charging current, and good chargers also cut the charging current off when the right voltage is reached.
ConverterA converter changes AC house current (120 volt in North America) into 12 volt DC battery power. Current production of Converters are also smart battery chargers to keep your battery up while not over charging it. InverterAn inverter takes 12 volt DC battery power and converts this electricity into 120 volt ac power.
What you will need is a 240 to 120 step down transformer. An adapter might work but it depends on what the current draw of the neon sign is at 120 volts.
If it is a 120/240V receptacle (such as for a dryer), then yes, there are two 120 volt leads and a neutral in the 240 circuit, the adapter is just using one 120 volt lead and the neutral to convert it to a 120 volt circuit.If the circuit is just 240V, then there is no neutral.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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
No, you will need to obtain an adapter to change the 120 volts to 230 volts. The adapter must be sized to the load wattage of the 230 volt appliance. To find the load wattage multiply the amperage times the voltage of the appliance. Once this is assessed, the size of the adapter or transformer will be of equal or greater value than that of the connected appliance. The adapter will be rated in VA or KVA depending on the needed load amperage.
Your question is confusing. First off a battery charger puts out DC voltage not AC. If you are asking if you can run a 120 volt battery charger on a 220 volt circuit the answer is no you cannot. That would destroy the charger.
