Specific Recharge Times of Your Phone

by Agnessa K

Here are some specific recharge times if you haven’t got time to be doing the math.

Here are the 2 popular capacities, 10,000 mAh and 20,000 mAh.

So a 10,000 mAh power bank fully precharged can fully charge your iPhone:

iPhone 7: (10,000×3.7 / 5) x 0.85 / 1960 mAh = 3.2 recharges

iPhone 8: (10,000×3.7 / 5) x 0.85 / 1,821 mAh = 3.4 recharges

iPhone X: (10,000×3.7 / 5) x 0.85 / 2716 mAh = 2.3 recharges

Galaxy S8: (10,000×3.7 / 5) x 0.85 / 3000 mAh = 2 recharges

Galaxy S9: (10,000×3.7 / 5) x 0.85 / 3000 mAh = 2 recharges

So a 20,000 mAh power bank fully precharged can fully charge your iPhone:

iPhone 7: (20,000×3.7 / 5) x 0.85 / 1960 mAh = 6.4 recharges

iPhone 8: (20,000×3.7 / 5) x 0.85 / 1,821 mAh = 6.8 recharges

iPhone X: (20,000×3.7 / 5) x 0.85 / 2716 mAh = 4.6 recharges

Galaxy S8: (20,000×3.7 / 5) x 0.85 / 3000 mAh = 4 recharges

Galaxy S9: (20,000×3.7 / 5) x 0.85 / 3000 mAh = 4 recharges

Note: These examples also work for devices such as tablets and cameras.

As you can see with the 20,000 mAh power bank, it charges the devices twice as fast as the 10,000 mAh power bank. If you have a new device that uses a large battery, you’re going to need a power bank with a large battery capacity.
