Yes - what matters is the voltage - it has to be the same. The device will only draws 1A as needed - the adaptor with higher amp,i.e, 2A is fine. As long as the adaptor has amps equal to or greater than
those of the device, it will be ok!
the excess 500mA will not be used, hence, it will not damage your device. Just make sure you have the proper voltages.
Yes. As long as the voltage is the same which it is. The 800mA is the capacity that the transformer can produce safely without going into an overload state. Your original adapter was rated at 500mA which means that what ever device was plugged into it draws less that 500mA. You might notice that the new adapter is slightly physically larger. So you are safe to use the new adapter with the higher rating.
Yes it will
No, underpowering will not "power" the device, it will not run. You must get an adapter that is 6V and (2A or higher) will be ok as well.
No the higher voltage could damage the device connected to it.
damage the device, motherboard, or adapter.
You would overload and damage the device and/or the adapter.
It may work,but the phone device will be underpowered and it may not function to its full potential,like range,signal clarity. But on the other hand,your adapter will be overloaded and may heat up,leading to a short life. Rajiv Modi
Yes, the manufacturer specifies what the working voltage of a device will be and that voltage has to be adhered to.
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.
A display ADAPTER is neither. The Display is an output device.
Communication device
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.
