Can I use a higher amp power supply for my monitor?
4 Answers. The amperage rating on your power supply simply means that the supply can put out up to 2 amps, so as long as the voltage matches (12 volts) you could safely use a higher amp power supply for your device.
Can you interchange AC adapters?
As long as the voltage is the same on the adapter and on the device (also, I have 9V DC and 9V AC adapters, do not mix these up) and be sure the current required is less than the amount that the adapter can source otherwise you risk overloading the power supply.
Can I use a charger that provides the same voltage but a lower amperage?
No, amps do not have to match, but the power supply or charger must be able to supply enough amps as required by the device being powered or charged. In practical terms, that means the amperage rating of a power supply or charger must match or exceed that required by the device it is connected to.
Can I use a higher power adapter for my Device?
Usually, a higher power adapter will be more expensive, so if you have the option just match the device’s power. Your device is unlikely to operate if you have an adapter with a lower A or mAh output then the device, and if it does operate the adapter is likely to get very hot and could be dangerous. Amps and volts what about Watts?
Can I replace an AC adapter with a bigger wattage adapter?
Replacing an AC adapter with one that has double the amperage is fine. Replacing one with 20x the amperage is riskier. Wattage is volts x amps, or the total amount of power available. Often if an adapter tells you amperage, it will omit wattage, or vice versa. You can use one to figure out the other.
What is the difference between voltage and current in power adapters?
Voltage is measured in volts (V), and current is measured in amps (A). (You’ve probably also heard about resistance (Ω), but this doesn’t usually show up on power adapters.) To understand what these three terms mean, it helps to think of electricity as water flowing through a pipe.
What should I look for when buying a power adapter?
Make sure the power adapter is not only the right voltage but is able to handle the needed power to supply your device with enough voltage to operate.
