The phone will never charge.
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 need to convert a 110-volt outlet to 115 volts as they are essentially the same. The slight variation is within the normal tolerance range for electrical systems. If you need to use a device that requires 115 volts, you can safely plug it into a 110-volt outlet without the need for an adapter.
The output of a 12 volt transformer is an alternating current (AC). Your adapter is a 12 volt transformer but it has a built in half wave or, more expensive ones, a full wave bridge rectifier. What this rectifier does is change AC to DC. Bridge rectifiers are cheap to purchase. Connect it to the output of the 12 volt transformer and you will get a DC voltage. Great little project.
No, it is not recommended to use a 19-volt output adapter for a device that requires a 12-volt output. Using a higher voltage adapter can damage the device and potentially create a safety hazard. It is important to always use the correct voltage adapter specified by the manufacturer.
It is not recommended to use a 15 watt converter for a 9 volt appliance as the voltage output may be too high, potentially damaging the appliance. It is best to use a converter that provides the correct voltage output for the appliance to ensure safe operation.
That appliance might last longer if you use an eight volt adapter rather than a nine volt adapter.
No
No, the voltage from the adapter should match the voltage required by the appliance.
Use a universal adapter.
nothing its ok to use it theres is a tolerance of at least 10% meke sure positive and negative match
No.No.
No, the voltage is too high.

No. You should use the adapter specified for the DVD player. Using the wrong adapter can damage the DVD player and/or the adapter and/or cause a fire.
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.
If your equipment is from North America then yes you will need an adapter as the Australians use a 230 volt system.
No, the unit might work but the low voltage will cause unit to stop.
