Watt-Hour, or Wh, is a more accurate unit to show the power capacity than Amp-. Hour (Ah) that was used before. For example, 4000 mAh at 11.1V means the battery capacity is 4000 mAh x 11.1V = 44.4 Watt-hour (Wh). 4000 mAh at 14.8V means the battery capacity is 4000mAh x 14.8V = 59.2 Watt-hour (Wh).
Accordingly, how many phone charges is 10000mah?
Generally speaking, a good rule of thumb is to divide the mAh of 10000mAh power bank by the mAh of your device battery. So a 10000mAh power bank can “theoretically” charge an iPhone 4s plus from 1-100% 4.1 times (10000 / 1810 = 5.5). --iphone6/6s battery capacity is 1810 mAh.
How long is 20000 mAh?
Your power bank is 20000mAh or in simple terms 20Ah. That means your poer bank can give 2Amp for 10 hours (2*10 = 20) or 1Amps for 20 hours (1*20 = 20). The hour value might change based on the C rating of the battery. No how much time will you need to charge it depends on the charging current.
How many mAh is the iPhone 6?
This is compared to 2915 mAH battery in the iPhone 6 Plus, about a 5% reduction. This mirrors the already-known battery capacity reduction in the 4.7 inch iPhone 6s, which has a 1715 mAH battery. This is also 5% smaller than the 1810 mAH battery in the iPhone 6.
