Can a 9 volt 1000 m a adapter replace a 9 volt 200 m a adapter- the polarity is the same-this is not bein used as a charger its being used to power a guitar effect pedal in place of 9volt battery?
Some 9 V adapters rated for 1000 mA will provide 9 V at 1000 mA. If you use it on a 200mA device the voltage may go up to 10-15 V and if that device can not handle the higher voltage, it it could burn out. Better adapters will only put out 9 V exactly and have no problem. Be careful of revere polarity where the positive on one is the negative pin for the other adapter.
Can a 12v dc 500mA adapter be substituted for a 12v dc 200mA ac adapter?
No.If it is AC output, it will blow out the power circuits of the DC device.If it is DC output, it doesn't have enough current capacity for the load of the DC device.If you want to power a DC device with a wall wart, make sure the wart is:DC outputCorrect polarity (some have reversible polarity)Exact same voltage as the deviceGreater than or equal to current rating of the device
I have my 120 volt appliance and in Philippines we have 240 volt. Can a 110 - 250 volt adapter be used?
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.
Can a 12 volt 0.5 amp ac adapter substituted with a 7.5 volt 1 amp adapter?
No, it is not recommended to substitute a 12 volt 0.5 amp AC adapter with a 7.5 volt 1 amp adapter. The voltage and amperage ratings need to match the requirements of the device you are powering. Using a lower voltage adapter may not provide enough power, and using a higher voltage adapter can potentially damage the device.
Will a 9 volt 800 milliamp adapter work with a 9 volt 400 milliamp device?
Yes, the 9 volt 800 milliamp adapter will work with the 9 volt 400 milliamp device. The device will only draw the amount of current it requires, so having a higher amperage rating on the adapter is fine. The voltage should match to ensure compatibility.
Can you use a 9 volt adapter for an 8 volt appliance?
That appliance might last longer if you use an eight volt adapter rather than a nine volt adapter.

How can I convert a 240 volt power source to a 120 volt power source using a 240 volt to 120 volt adapter?
To convert a 240 volt power source to a 120 volt power source using a 240 volt to 120 volt adapter, simply plug the adapter into the 240 volt outlet and then plug your 120 volt device into the adapter. The adapter will step down the voltage from 240 volts to 120 volts, allowing you to safely power your device. Make sure the adapter is rated for the appropriate wattage to avoid damaging your device.
Can a 4.5 volt ac adapter power a game that says to use 5 volt adapter?
No
Can a 12v dc 500mA adapter be substituted for a 12v dc 200mA ac adapter?

Do you have a 230 volt plug adapter for sale?
Yes, we have a 230-volt plug adapter available for purchase.
Can you use a 9v 600Ma adaptor to power a 9v 300Ma appliance?
I think you mean to ask if one can use a 9v 600mA adapter to power a 9v 300mA appliance. Yes, you can do that. A 9v 600mA adapter will deliver 9v at up to 600mA. A mA is one milli amp, or one thousandth of an amp. 300mA is 300 thousandth of an amp, 300/1000 or 0.3 amps. 600mA is 600 thousandth of an amp, 600/1000 or 0.6 amps, and is twice the current of 300mA.
Can a 9 volt 100mA ac adapter be substituted for a 9 volt DC 300mA adapter?
No. an AC adapter will not work for equipment that needs DC.
Can a 6 volt adapter be substituted for a 9 volt adapter?
No, of course not. The 6v adapter only produces 6v, while the load expects 9v.
Can a 6 volt mA adapter be substituted for a 6 volt mA adapter?
It sounds like the same thing to me.
Can I use a 9 Volt 1 Amp power adaptor in place of a 5 volt 1.2 Amp adaptor?
No, the voltage of the replacement adapter must always be IDENTICAL to the original adapter and the current of the replacement adapter must be the same or larger than the original adapter.Trying to use a 9 Volt adapter to replace a 5 Volt adapter will almost certainly completely destroy the device the moment you plug it in.You did not say whether the adapters provided AC or DC or the polarity if DC. Either way both the replacement adapter and the original adapter must be IDENTICAL in this respect.
Can you use a 6 volt adapter on a 4.5 volt appliance?
No, the voltage from the adapter should match the voltage required by the appliance.
