A power bank''s input voltage is the voltage that it requires to charge the battery. Depending on the model, power banks usually require an input voltage between 5V and 20V. It is important to check the specific requirements of your power bank in order to ensure that it is properly charged.
Power efficiency is typically measured as a ratio or percentage of output power to input power. It''s calculated using the formula: Efficiency = (Output Power / Input Power) × 100%. For example, if a motor draws 1000 watts of electrical power and produces 850 watts of mechanical power, its efficiency would be (850 / 1000) × 100% = 85%. 5.

As a thought experiment, if you connected the AC input of the charger to a 140V DC supply and the charger''s output to a load resistor that took 2.1 Adc (10.71 watt load) and assumed the power conversion efficiency in the charger was 80%, you would expect to see about 14 watts taken from the input DC supply of 140V.
This extra power is turned into heat. So, the input power is always larger than the output power. In your example, the power adapter is rated to use a maximum of 58 W (0.24*240), but can output only 5*1.5=7.5 W. So, worse case based on the label, it will use 58 W, but only supply 7.5 W to your device, so about 13% efficient. Efficiency is ...
The charge moves at a drift velocity v d v d so the work done on the charge results in a loss of potential energy, but the average kinetic energy remains constant. The lost electrical potential energy appears as thermal energy in the material. On a microscopic scale, the energy transfer is due to collisions between the charge and the molecules of the material, which leads to an …

For your "Surface" device: If its power adapter says INPUT: 100-240v @ 1A, OUTPUT: 12v, 2.58A, That means the Surface would draw 2.58A maximum. 2.58A is continuous; this does not mean 2.58A per hour, it means 2.58A maximum every second, every minute, every hour. Same thing. But yes, per hour, it would use 2.58Ah (amp-hours, not amps). (Maximum.)
The energy output of a battery cannot be increased beyond its rated capacity. However, proper maintenance and usage can help maintain the battery''s energy output for longer periods.
