Yes, it should work. The device being charged will only take the amount of charge it needs and all the 300 milliamp rating means is that the charger provides an additional 200 milliamps of current.
Be sure though, to make sure the plug polarities match the one of the original and as long as you are sure the voltage rating is the same, you should be OK.
You may find that your device will charge a bit faster than it did. One other thing you need to know though. If the original adapter puts out 9 volts at 100 milliamps DC and the other adapter puts out 300 milliamps AC, they aren't compatible, and will most likely burn out your device being charged.
11-15v from batt.
A: Disregarding the fact of different voltages there is the power to be concerned 9v x 1A = 9W, 15V X .8 = 12W. THE DEVICE WILL BE UNDER POWER.
You will need a regulator circuit that will change the shape of the pulse AND regulate the voltage to 5v.
It depends on the value of the three resistors. If they are equal, then each resistor has 5 volts across it.

Almost certainly.
Yes you can. It will just take a little longer to complete the charge cycle.

No. The machine will notice that it isn't getting all the required voltage and won't run.
A electrical voltage of Fifteen Volts.
it regulates +15v constant at output.

, No. I did it powering a 15V peavey audio mixer using a lead acid 12V battery. But depending of your audio mixer, you may have levels problems. Emmanuel
