Specific Recharge Times of Your Phone
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.
