In a statement, the charging time essentially depends on the Portable charger you use. A formula to determine how long to charge a power bank:

 

Charging Time in Hrs. = (Power Bank Capacity in Mah) / (Charging Rate in Ma)

 

Actually, there are two factors will influence the charging rate: Output of charger & Input of Power Bank

 

Currently, maximum BEST POWER BANKS are produced with 5V 2A input model, which stands for the highest amount of flow it can take. Apparently, the Power Bank Charger you use to juice up like an external battery charger should be capable to give 2A current flow which specifically matches the requirements. However, estimating an estimated 15 percent power waste during charging / discharging method, the real input current would be 1700 mA (1.7A).

Using the formula above the Best 20000mah Power Bank rated charging time = 20000 mAh/1700 mA = 11.76 hours

If you apply a 1A rated portable charger, the charging time will be doubled to around 24 hrs, which is not that pleasant.
