Anker PowerCore 10000, One of the Smallest and Lightest 10000mAh External Batteries, Ultra-Compact, High-speed Charging Technology Power Bank for iPhone X/ 8/7, Samsung Galaxy and More (Black)

Product Information

Conventionally, the average American spends about five hours on the phone. The younger generation spends even more time, as many as eleven hours! Some smartphones boast of an impressive battery life because they have been specifically built to last a long time. For instance, the Realme 7 Pro can last as long as 21 hours on a charge cycle of fifteen minutes. For a brand we're not that familiar with, this INIU charger stood up in 15-minute and 1-hour timed charging (at 22%, 78%), with times that were within 1-2 percentage points ahead of the PowerCore Slim's times. It only failed to beat the Anker to fill a complete phone once, putting up a 2-hour time, four minutes behind the Anker. Both chargers refilled about 2.2-2.25 iPhone 12s, so it's practically a tie. INIU also has a longer warranty: its 3-year plan is twice as long as Anker's 18-month window.

Here is a conversion table converting common values of milliamp hours to amps, over a duration of 1 hour and 1 day. Milliamp Hours (mAh) If you want to do the conversion by hand, here’s the formula behind our Wh calculator: Wh = mAh × V / 1000 For example, let's say you have a 5000 mAh power bank that you want to charge in 2 hours. How much current does your charger need to output to charge it at that rate? 5000 mAh ÷ 2 hrs ÷ 1000 = 2.5 A Undeniably, we rely heavily on our smartphones. At the rate at which we use them, it is only expected that their battery life will reduce over time.

How many volts do power banks have?

So, your device used 6000 milliamp hours of energy. How to Convert Milliamp Hours to Milliamps (mAh to mA) hours, since 380*5=1900. Or for other circuits, it can supply 190mA of current for 10 hours, since 190*10=1900. If you are dealing with a new smartphone, the number of times a 10,000 mAh portable charger will charge this device may differ. This is because they have stronger batteries, which means a longer battery life. So, your 10,000 mAh portable charger will charge your new smartphone about one and a half times. Again, this also depends on the strength of your battery health. How Many Phones Will a 10,000 mAh Power Bank Charge? To calculate milliamp hours from amps and hours, you multiply the number of amps by the number of hours and then multiply the result by 1000. Ten percent also goes to energy loss through charging cables, making your power bank 90 percent efficient instead. When all these are factored together, you are getting 6,600mAh, which is good enough. How Long Does a 10,000 mAh Battery Last?

Since the iPhone 5 has a battery capacity of 1,560mAh, the Anker Astro E5 should be able to recharge the iPhone 5 approximately 10 times Now the same circuit powered by a D cell battery rated at 10,000mAH can power the circuit for 10000mAH/200mA= 50 hours. Thus, the D cell canIn that case, a power bank is a go-to option. A 10,000 mAh power bank can deliver 10 hours of juice to a smartphone that consumes 1,000 mAh. An average smartphone has a 2,000 mAh battery, which means you may be able to get three to four charge cycles because of your power bank’s real capacity. It’s also worth mentioning the fact that if the voltage is smaller than the voltage of your device, charging cannot occur. This is why all power banks come with a step-up voltage converter to produce the 5 Volts required for charging an external device.

So, for example, let's say there is a circuit that consumes 200mA per hour. With a AA battery rated at 2000mAH, it can power the circuit for

LED Light

Please bear in mind that all of these examples are calculated based on the average 3.7V value for standard Li-ion batteries. If you have batteries that have different voltages, you’ll need to redo the calculations using the correct voltage value. These examples work for most power banks, smartphones, and similar devices which generally come with 3.7V batteries. For a smartphone, a power bank with a 12,000 mAh capacity is more than necessary. Even a tablet with an 8,000 mAh battery can be charged. If your laptop has a 10,000 mAh battery, then the ideal choice would be a 20,000 mAh power bank.
