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.
No, you should not connect a 12V 50W light directly to a 12V AC 2A adaptor. The light requires a higher wattage than the adaptor can provide, which can damage both the light and the adaptor. You should use an adaptor that can supply the correct voltage and wattage for the light.
No, you cannot use a 12V 0.6A (7.2W) adapter instead of a 12V 1.5A adapter. The 0.6A adapter provides insufficient current for devices that require 1.5A, potentially leading to underperformance or damage to the device due to inadequate power supply. Always match the voltage and ensure the current rating of the adapter meets or exceeds the device's requirements.
If the camera actually uses 700 mA in order to do its job, then the 500 mA adaptor will warm up, then overheat, and eventually fail.
Yes.
No, a 9V 1A router adapter cannot be used for a 12V router. The voltage rating is critical, and using a lower voltage can lead to insufficient power supply, potentially causing the router to malfunction. Additionally, the 1A current rating may not meet the power requirements of the 12V router, risking damage to the device. Always use an adapter that matches the specified voltage and current ratings for optimal performance and safety.
Using a 20V adapter for a 12V machine can potentially damage the machine due to overvoltage. The machine might not be able to handle the higher voltage, leading to malfunctions or even permanent damage. It is important to use the correct voltage adapter to ensure the proper functioning and safety of the machine.
Yes - it will just take a little longer to charge the device.
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)
You can use a wired adaptor if you're using a game boy advance.
A SIM card adaptor will allow you to use a micro SIM in a standard SIM slot.
Yes and No. You have three types of adaptors: constant current with variable voltage output. constant voltage with variable current output. constant voltage with constant current output. What you are talking about is the latter. This means that the adaptor was created for a specific appliance requiring 12V/2A, which it will indeed use. Heavier appliance will not draw enough current/voltage and will malfunction. Lighter appliance will draw too much current/voltage and will overload/shortcircuit.
