Yes, a 9 volt 1600 mA AC adapter can be substituted for a 9 volt 300 mA adapter.
The mA number represents the highest allowable current to be drawn from the adaptor. The adaptor that you want to replace has only 300 mA maximum capacity. The new adaptor has five time the capacity of the old one which means that devices that draw up to 1600 mA can be connected to it.
Depends on what you are pluging into.. if could possible run unit hot..
No. an AC adapter will not work for equipment that needs DC.
It sounds like the same thing to me.
No, of course not. The 6v adapter only produces 6v, while the load expects 9v.
No the higher voltage could damage the device connected to it.
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.
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.
No adapter is needed, 110 and 115 volt are interchangeable.
Yes there is
Use a universal adapter.
No HP adapter only can used in the HP laptop , as the laptop has its own input volt , only the orginal adapter can offer the right output volt.
