No
Yes, you can run a 4.3v device with a 5v power adapter as long as the amperage of the 4.3 volt device is under the amperage capacity of the 5 volt adapter.
That appliance might last longer if you use an eight volt adapter rather than a nine volt adapter.
No, get a matching transformer and check the polarity and the milliamps.
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.
No, of course not. The 6v adapter only produces 6v, while the load expects 9v.
No. an AC adapter will not work for equipment that needs DC.
The car adapter is designed to attach it to a 12 volt power source in a car.Other adapters have other purposes.
It sounds like the same thing to me.
better yet get six 9 volt clip outs from radio shack and tie them to a wall adapter that is already on the market. Make sure you get an 9 volt adapter that will supply enought current to power all six devices at the same time.
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.
No, the voltage from the adapter should match the voltage required by the appliance.
No adapter is needed, 110 and 115 volt are interchangeable.
