No. If it works at all, it will be underpowered, and possibly damage the speakers.
To power 12V speakers, you have to have an adapter with EXACTLY 12V (no more, no less), and at least 1A. You could hook up a 12V 4A adapter if you wanted to, your speakers would just only draw 1A of power.
Make sure you use a 12V adapter though!!
No, the new adapter will not be able to safely supply enough current.
I wouldn't recommend it ! If the device needs to draw more current than is available - the adapter could overheat, posing a fire risk.
no, it may damage the appliance.1Can_12V_2A_adapter_be_used_for_12V_1A_device, 2a adapter cannot be used for 12v, 1a device if the so mentioned parameters are input parameters of the device.Yes, a 12 volt 2 amp adapter has more that enough capacity to operate a 12 volt 1 amp device. In fact the adapter can operate devices up to a limit of 12 volts 2 amps. A device larger than 2 amps connected will tend to heat the adapter up and eventually cause it to fail.
No.If it is AC output, it will blow out the power circuits of the DC device.If it is DC output, it doesn't have enough current capacity for the load of the DC device.If you want to power a DC device with a wall wart, make sure the wart is:DC outputCorrect polarity (some have reversible polarity)Exact same voltage as the deviceGreater than or equal to current rating of the device
The best wifi adapter for the Nikon D3300 camera is the Nikon WU-1a Wireless Mobile Adapter.
Output: 5V 1A
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.
Using a 7.5V adapter rated for 1A instead of a 7.5V 2.1A adapter is not advisable. The lower amperage adapter may not provide sufficient current for the device, potentially causing it to underperform, malfunction, or overheat. Additionally, if the device attempts to draw more than 1A, it could damage the adapter or lead to instability. It's best to use an adapter that meets or exceeds the required specifications.
A 9V 1A adapter will supply up to 9 Watts of power and a 9V 200mA adapter delivers up to 1.8W of power. The 200mA adaptor may not be able to supply enough power to a device that has been supplied with a 1A adapter. The 1A adaptor should operate equipment that originally used a 200mA adapter. Before using a different power supply, check that the outputs are both DC or both AC. If they are both DC, it is important to check that the polarity at the connector is the same for both. If AC and DC supplies are swapped or the polarity is swapped there is a risk that the equipment will be damaged.
If it were just 12V to 5V we would be talking about a simple regulator. Since we are also talking about 1A to 2A, we are talking about some kind of inverter, perhaps a pulse width modulated power converter.
The battery is more likely to be marked 12 v 1 Ah, meaning 1 amp-hour, so it can supply 1 amp for an hour, or ¼ amp for 4 hours etc.
V = ir i = v/r i = 12/12 i = 1a
