In general no, it might do some damage to both the equipment and the power supply. In certain specific cases it might be all right if you are able to measure the current to make sure it is 500 mA or less, and you can also ensure that the appliance can withstand 15 v.
Running 12V DC LED lights with 15V DC is generally not recommended, as the higher voltage can lead to overheating, reduced lifespan, or even damage to the LEDs. Most 12V LED lights are designed to operate within a specific voltage range, and exceeding that can cause them to draw more current than they are rated for. If you must use a 15V supply, consider using a voltage regulator or a buck converter to step down the voltage to a safe level for the LEDs.
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.
Just connect the circuit. It will only draw the amps it needs to operate. It is just like connecting a 100 watt light bulb that draws way less than 1 amp, to a 20 amp household circuit.
yes uou can use but you have to use external battery charger 13.5 v-15 v, 5 amp charger .

input voltage is strictly according to applications. If use 12V dc adapter power 5V dc device, the 5v dc device would be damaged.
Probably not. The other way around would be fine: a device that only needs 750mA will work fine on a 2A power supply, but one that needs 2A will NOT work on only 750mA, which is less than half the current required.
i am not sure, BUT according to the answer in this post:Can_you_use_a_9V_600mA_adapter_on_a_9V_400ma_scanneryou need an adaptor of 9v and AT LEAST 500mA (assuming that the appliance draws 500mA)

Yes, you can use a 500mA charger for a 400mA device. The device will only draw the amount of current it needs (400mA) from the charger, so there is no risk of overloading it. However, ensure that the voltage of the charger matches the device's requirements to avoid potential damage.
Yes.
Almost certainly.
Yes - it will just take a little longer to charge the device.
Yes you can. It will just take a little longer to complete the charge cycle.
You can use any 9v adapter as long as the output amperage is rated higher than the amperage rating of your appliance so yes a 600ma adapter can be used to power a 500ma or 400ma appliance
Yes, you can use a 300mA power supply in place of a 400mA supply, but it may not provide enough current for the device to operate properly. If the device requires 400mA and only receives 300mA, it may underperform, malfunction, or even be damaged due to insufficient power. It's important to ensure that the power supply meets or exceeds the current requirements of the device for safe and effective operation.
No. Your portable radio needs 800mA to operate. Your adapter can only produce 400mA. If you make the connection the adapter will rapidly heat up and probably burn out.
