What else can I help you with?
Can you use a 12v halogen bulb with a 6v AC adapter - wattage is the same?
No, you cannot use a 12v halogen bulb with a 6v AC adapter. The voltage of the bulb must match the voltage of the adapter for them to work properly. Using a higher voltage bulb with a lower voltage adapter can cause the bulb to burn out or potentially damage the adapter.
Can you use a 13v 2.77 amp ac adapter in place of a 12v 3.0 amp ac adapter?
It is not recommended to use a higher voltage adapter than what is specified for your device. Using a 13V adapter instead of a 12V adapter may damage your device due to overvoltage. It is best to use the adapter with the exact voltage and current specifications that are recommended by the manufacturer.
Can you use 5v ac adapter instead of 4.5v ac adapter?
Yes the voltage is close enough to work. What you have to be cautious about is the milliamp output of the adapter. Make sure that the output of the adapter is higher than the device that plugs into it.
What are the advantages to having a higher wattage ac adapter for a notebook?
You should not use a power adapter with a higher voltage output than the input rating on the computer. It can cause damage to the computer and the battery. You can use a lower voltage. If you do and you are using your computer, it might not charge but it will prolong the time you have before it runs out. If you do not use it, then it will charge but slower than with the correctly rated power adapter.
Can I use a laptop ac adapter with the same volts but higher amps?
Using a laptop AC adapter with a higher amperage rating should be safe, as the laptop will only draw the amount of current it needs. However, using an adapter with a much higher voltage could damage your laptop. Always match the voltage and polarity exactly, and ensure the amperage is equal to or higher than the original adapter.
What is the voltage adapter for use in European countries?
Step down transformer from 220 volts AC to 110volts AC
Ac adapter is it ok to use lower voltage 19v 4.74a ac adapter has died. Can I use a spare I have in the mean time it's output is 12v and 5a?
not unless you want to fry your electronics
Can you use 12v ac 60w instead of 12v ac 2a adaptor?
Probably yes. The 12v 2 amp adapter can put out 12x2=24 watts. The 60w adapter can handle more than twice the power (60 / 12 = 5 amps). However, the voltage of inexpensive adapters may be quite a bit higher under low loads. I'd check and make sure the voltage was not very much greater than 12 volts with a 2 amp load.
High voltage low amp adaptor I have the original power adapter for my laptop. The output rating for the ac adapter is 19v 3.42A. I have a replacement that has a 30v and 2.5A.Can i use it.?
NO!!!!! Find a charger with the same voltage!! If not, you will fry your battery. The only electrical number you can go higher on is the milliwats.
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.
Can you use a 3.7v ac adapter for a digital camera that recommends a 4.3v adapter?
NO! It will fry your device. Use same V and possibly higher amp rated adapter.
What if I Used wrong ac adapter in electronic device?
If the AC adapter gives too little voltage, the electronic device will probably not work. If it gives too high a voltage, you will probably burn out the electronic device, which will have to be replaced or rewired. If the AC adapter is too weak (provides less milli-amperes than the device needs), the AC adapter can burn out. In summary, you need to check: (a) that the adapter should have the correct voltage, and (b) that it provides the required amount of milliamperes (or more) for the device.
