A 5 V, 3 A supply does not continuously push 3 A into every connected load. The load draws current according to its circuitry, while the source must keep its output within specification up to the current it is designed to provide.</p> <p>The interesting case begins when the device would benefit from more power than the source can supply. Depending on the charger, cable, charging protocol, and device power-management circuit, the result can be slower charging, reduced input voltage, source shutdown, repeated reconnects, or battery discharge even while the charger remains connected.</p>
