Consider a power bank with an energy content of 37 Wh and a capacity of 10 Ah. Compared to the residential battery System A with a capacity six times as large, the energy content of the power bank is as much as 264 times smaller. This is due to the difference in internal voltage, as the power bank battery voltage is only 3.7 V.
E = 50 W × 2 hours = 100 Wh = 0.1 kWh. In summary, power represents the rate of energy usage, while energy consumption measures the total amount of energy used over a specific period. Power is the instantaneous value, while energy consumption is the cumulative value over time. 0 like 0 dislike.
