How much electricity (to the closest 10 kilowatt-hour) does it take to power your iPhone or Android for a year? 1 kWh? 10 kWh? Or 100 kwh?

How much electricity (to the closest 10 kilowatt-hour) does it take to power your iPhone or Android for a year? 1 kWh? 10 kWh? Or 100 kwh?     The answer: 1 kWh. This is the amount of electricity you’d need to power ten 100-watt incandescent lightbulbs for an hour. Far from anything worth being […]


EPRI Calculates Annual Cost of Charging an iPad at $1.36

EPRI calculations show that the average energy used by all iPads in the market is approximately 590 gigawatt hours (GWh). In a scenario where the number of iPads tripled over the next two years, the energy required would be nearly equivalent to two 250-megawatt (MW) power plants operating at a 50 percent utilization rate. A […]


Considerations for user on battery charging

Avoid charging a battery faster than 1C; a more moderate charge rate of 0.7C is preferred. Manufacturers of electric powertrains are concerned about super-fast charging of 20 minutes and less. Similarly, harsh discharges should be avoided as also this also adds to battery stress. Whether it’s an EV, e-bike, a flying object, a portable device […]
