No. The device will try to draw 700 milliamps which will overload the 300 milliamp adapter most likely causing it to burn out and possibly catch fire.
No, the adapter's power output has to be equal to or greater that the current draw of the device.
No, a power adapter must supply the same voltage, same polarity, and at least as much current as the load requires. Your adapter can only supply 300mA, which is less than the 700mA required by the load.Your game probably will not turn on and the power adapter may be damaged.
No, if the device needs 700mA of current, your power adapter cannot supply adequate current.
Yes, you can use a 300mA adapter on a 1A device, but it may not work properly or could damage the adapter. The device may draw more current than the adapter can provide, leading to insufficient power, potential overheating, or failure of the adapter. It's always best to use an adapter that meets or exceeds the device's current requirements for optimal performance and safety.
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.
I think you mean to ask if one can use a 9v 600mA adapter to power a 9v 300mA appliance. Yes, you can do that. A 9v 600mA adapter will deliver 9v at up to 600mA. A mA is one milli amp, or one thousandth of an amp. 300mA is 300 thousandth of an amp, 300/1000 or 0.3 amps. 600mA is 600 thousandth of an amp, 600/1000 or 0.6 amps, and is twice the current of 300mA.
Using a 12V 500mA power supply instead of a 12V 300mA power supply will likely be fine as long as the voltage matches, but the higher current capacity (500mA) means the power supply can deliver more current if needed by the device. The device will only draw the current it needs, so having a higher current capacity power supply should not cause any issues.
The UA-1506C is an AC adaptor designed to convert 120V AC power from a wall outlet into a lower voltage DC output suitable for powering or charging devices. While it may be used for charging, whether it functions specifically as a charger depends on the device it is intended to power. Always check the device's requirements to ensure compatibility with the adaptor.
Most probably you are using a AC (117V or 220V) to DC 6V converter adapter. If yes, then the answer is no, you cannot use a lower current rating for a device that draws more current. If you plug in a device that needs DC 6V 500 mA to an adapter that can only supply DC 6V 300mA, then the adapter could start sending higher than 6 volts current which may damage your equipment or overheat the adapter. If you are using a higher mA rating adapter, then it's okay. For more technical details, see: http://www.jaycar.com.au/images_uploaded/plugpack.pdf
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.
The amperage rating (800 mA) of a wall power transformer/converter is simply the maximum current that the unit can supply, so the 300 mA device will only pull 300. It's okay to use the 800 mA rating. On the other hand, the device requires 6 V, and the transformer is rated for 5 V. Most of these transformers will give slightly more voltage than they are rated, but don't count on it. It might work and it might not, but it isn't dangerous.On the other hand, you shouldn't use a transformer with higher voltage unless you are willing to risk damaging the device.Of highest importance is to make sure the + and - polarity of the transformer and the device are the same as each other.
The voltage would match but the amount of power would likely not be enough to run the device. Under-power will not likely harm the device, but it won't work correctly. Always use the correct voltage/power for your devices!
