Youshould not leave your power bank charging longer than necessary. Your manufacturer's instructions should let you know roughly how long it will take to charge. Most power banks charge within 1-2 hours.
A10,000mah power bank is going to last 10 hours on a device that uses 1,000ma an hour. If the device uses 500ma, the power bank is good for about two hours. Power Bank Capacity Explained
4years ago. Updated. The time it takes to recharge your power bank is dependent on a number of factors such as the size of your power bank battery (mAh) and the wall charger you're using. Below is our table that shows approximate charge times for each sized power bank for the different type of wall charger you're using. Withhigher quality components like you find in the Cascade, you can expect to get about 80% of the total charge transferred to your device. That's why we tell our customers to expect the Cascade 10000mAh power bank to recharge their smartphone about three times and the 6000mAh Cascade power bank about two times. Whenit comes to a 10000mAh power bank, it means that the power bank is capable of storing and delivering a total of 10000 milliampere-hours of power. This capacity is quite popular as it strikes a balance between size, weight, and charging capabilities.Agood quality charger or cable can charge your 10000mAh power bank in about 1 hour and 30 mins if the other factors also align. But a faulty or poor-quality cable or charger will take longer than 2 hours.
So this means a 10000mAh power bank can charge 3000mAh smartphone twice. Factors That Affect Real-World Charging Efficiency and Actual Power Delivered. Qualcomm Quick Charge (QC): Qualcomm's fast charging standard reduces charging time by many hours. A QC 3.0 charger with a high capacity can fully charge a 3000mAh battery in less than an 604D.
