Your quick reference for understanding technical terms used in our reviews and guides.

---

A

Amps (Amperes): The unit of electrical current, representing the flow rate of electrons in a circuit.

G

GaN (Gallium Nitride): A high-performance material used in modern chargers that allows them to be smaller and more efficient than traditional silicon-based chargers.

P

Power Delivery (PD): A fast-charging standard that allows devices to negotiate higher power levels over a USB connection.

V

Volts (Voltage): The electrical potential difference between two points, often described as the “pressure” that pushes electricity through a circuit.

W

Watts (Wattage): The total unit of power, calculated by multiplying Volts by Amps (V x A = W).
