Understanding the Basics: Voltage, Amperage, and Watts

To grasp the compatibility of chargers, we need to understand the fundamental concepts of electricity. Chargers work by converting AC (alternating current) power from your wall outlet into DC (direct current) power that your devices can use. The key specifications to consider are voltage, amperage, and wattage.

Voltage (v)

Voltage is the electrical potential difference, essentially the ‘pressure’ pushing the electricity through the circuit. Most modern smartphones, including iPhones, operate at a standard voltage of 5V for charging. The voltage output of both iPhone and iPad chargers is typically 5V, ensuring compatibility in this regard.

Amperage (a)

Amperage, or current, is the measure of the flow of electrical charge. It’s the amount of electricity moving through the circuit. The amperage of a charger determines the rate at which it can deliver power. iPad chargers generally have a higher amperage than iPhone chargers, which is a crucial factor in the charging speed.

Wattage (w)

Wattage is the measure of power, calculated by multiplying voltage and amperage (Watts = Volts x Amps). It indicates the overall power output of the charger. A higher wattage charger can deliver more power to the device, potentially resulting in faster charging.

For example, an iPhone charger might be rated at 5V and 1A, resulting in 5W of power (5V x 1A = 5W). An iPad charger, on the other hand, might be rated at 5V and 2.4A, resulting in 12W of power (5V x 2.4A = 12W).
