The output on the first laptop''s power supply is 15.6 V at 8.0 A. The output on the second laptop''s power supply is 15.6 V at 5 A. Clearly the voltages are the same, but the currents are different. I assume the second laptop''s power supply can not be used on the first, because it can''t supply enough power to the laptop.
$begingroup$ I suspect they themselves don''t quite know what they mean by ''drawing'' current. However, a "load" is essentially a device to which power is delivered.Thus, increasing the load on, e.g, a motor, requires the motor to deliver more power and, assuming the voltage to the motor is (more or less) constant, this means an increase in current through the …

Battery Design: The construction and quality of the battery components also play a role. Poorly designed or manufactured batteries may experience voltage irregularities. Age of the Battery: Over time, batteries naturally degrade. An older battery will typically have a lower voltage due to reduced chemical efficacy.
@MrClan Watts (W) literally equal Volts (V) x Amps (A), but Volt-Amps (VA) normally means a slightly different thing. It''s explained pretty well here, but basically VA refers more to how much power is traveling through the wire, and W more to how much power is "consumed"/"used" (dissipated) at the end.As the linked answer states, some of the VA power …
battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power. A 1E rate is the discharge power to discharge the entire battery in 1 hour.
So, for 3-cell, it comes up to 12.6 - 12.9 V of input. The external power supply must provide this headroom, which includes minimum of "drop-out" (or regulation) voltage for switching electronics inside the external power supply and internal charger, 1-2 V per device, give or take. Eventually it comes up to 12.9+4 = ~ 16-17V.
