A one amp adapter is the same as a 1000 mA adapter. If your device requires 500 mA to operate then there is ample capacity in the adapter to operate a 500 mA device. Be sure to match the type of voltage AC or DC from the adapter to the driven device. Both have to be the same.
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.
It allows you to use mains power instead of batteries
no because it is not ideal to have it because if you have a computer or game console you will have everything instead of having nothing in pe
i think that cell phones should be allowed in school because you could have everything on your phone and instead of having everything in hand
No, if you use a 6 volts adapter instead of a 9 volts adapter, you will be supplying 3 volts too little to the item that requires 9 volts. Either it may not work properly or it won't work at all. The fact that the 6 volt adapter can supply more current (2000 mA instead of only 1200 mA) won't help solve the problem of having insufficient voltage.
An adapter class is a class that provides a dummy (empty) implementation for an interface. That way someone who wants to implement the interface but does not want or does not know how to implement all methods, can use the adapter class instead, and only override the methods he is interested in.
Not that anyone knows of. Microsoft is pretty firm about wanting you to use ONLY Microsoft products with their systems. Sorry.
Because if that battery should run out of power during the installation, you will have to start over from scratch.
With caution - yes. The higher voltage shouldn't cause any harm to the phone - due to circuitry built into the phone to 'smooth out' the voltage from the original charger. However - don't leave it connected for long periods once it's charged. It will take less time to charge the battery (due to the higher voltage). I've used 'replacement' chargers with phones in the past without any problems.
An airline adapter is for use of modern headphones. Older planes and headphones used 2 mono audio jacks instead of 1 stereo jack. The adapter brings the 2 mono jacks into 1 stereo jack, so that modern headphones can be used on board the plane.
If it is not the proper power adapter then you put both the electronics and the performance at risk. Reducing the available power by 60% isn't a particularly good idea.
