Jul 28, 2017 · Input amps/volts don''t matter in the slightest. Only thing that matters is the output and with laptop chargers, if the voltage is correct you can ostensibly move up to as much as
Mar 18, 2025 · When it comes to building or upgrading a PC, one of the most critical components to consider is the power supply unit (PSU). The PSU is responsible for providing power to all
The difference between amps and wattage is fundamental to understanding electricity. While watts measure power consumption, amps measure the flow of current. Both are crucial for managing electrical loads, choosing the right appliances, and maintaining a safe electrical system.
Meanwhile, an appliance with a high amperage rating might require a dedicated circuit to handle the higher current flow without tripping a breaker. The relationship between watts and amps is defined by the equation W = A x V, where W stands for watts, A stands for amps, and V stands for volts (the measure of electrical potential difference).
There is no set number of watts in an amp, as the number is determined by the circuit's voltage. A 12-volt circuit with a 10-amp current produces 120 watts, but a 120-volt circuit with the same 10-amp current produces 1,200 watts. In this example, the voltage is what manipulates the wattage. What is the difference between a watt and an amp?
In a nutshell, the Amps rating on a power supply, charger or adapter explains the maximum amount of current that it can safely provide in an hour. Any amperage of charger rated above what's required for your device is safe to use with your device, providing the PSU voltage is the same as the input voltage or within a tolerance of 1 volt.
Volts (V) measure the pressure pushing electrical current through a circuit. Amps (A) measure how much current flows through the circuit. Watts (W) measure the total power consumed or generated. For example, if you have a device that requires 1,200 watts and your home operates at 120 volts, the current needed would be 10 amps.
What Is an Amp? An ampere (A), or amp, is the unit of electric current that measures the flow of electrons through a circuit. It tells you how much electricity is moving through a wire at any given time. Think of it as the volume of water flowing through a pipe—the higher the amps, the more electricity is flowing.
