No, a power adapter does not have a one size fits all type scenario. Each power adapter is set to convert a certain amount of volts or watts to enter each specific computer. Each power adapter has a specific power rating, either in volts or watts, that it can handle and output to a certain device.
In many instances, yes. The central function of AC adapters is the conversion of mains current from AC to DC for electronic devices with a rechargeable battery.
The unit for voltage is volt (V), while current ratings end in amps or ampere (A). Power adapters have AC inputs and DC outputs. Depending on the region, AC input can be 110/120V or 220/240V. To make it easier for users to choose an AC adapter, manufacturers usually offer adapters that support both voltages.
Below is the compatibility range:
Voltage Range: The voltage capacity of the adapter should be within 10% of the capacity of the computer.
Wattage Range: The wattages of both the adapter and the computer have to be equal.
Current Range: The current of the power adapter should never be lower than that of the computer.
Standard receptacles will work for DC or AC. You must exercise caution in using both in the same household. Plugging a 12V DC load into a 120V AC socket may fry the load if the circuit breaker/fuse doesn't pop first. ways to handle this situation.
If we connect an AC supply to the DC devices and equipment: The positive and negative voltage will destroy (this is not always the case) some of electronic components such as transistors and electrolytic capacitors. In case of higher AC voltage, they may burn with blast and catch fire.
One way to determine if you have an AC-DC power supply or a DC-DC model is to look at the device itself. Often, the input and output information will appear somewhere on the surface. If the input is AC, you have an AC-DC power supply, and you have a DC-DC model if the input and output both are DC.
12V power supplies can be of two types: 12V regulated power supplies, and 12V unregulated power supplies. 12V regulated power supplies come in three styles: Switching regulated AC to DC, Linear regulated AC to DC, and Switching regulated DC to DC.
