How much mAh charge is enough?
To get a rough idea of how may times your device can be charged by a given power bank, you first need to know the battery capacity of your gadget. For example, an iPhone X has a 2716mAh battery. Double that number (5400) and divide the powerbank capacity by this amount. This gives you a very rough idea of how many full charges you could get. You can inflate this number by working in the highest efficiency zone, recharging your device from no less than 20% to no more than 80% - this will give you the most charge duration overall!
Note: This powerbank device should be charged from a wall charger with 2A or greater output. Charging from computers, laptops or wall chargers with 1A or less will take longer and be less efficient. Disconnect devices once it is fully charged.
