How Long Do Portable Power Banks Take to Charge? For example, if you plan to charge a tablet and smartphone at the same time, be sure to choose a charger that gives you enough juice. For chargers with multiple ports, make sure you are accounting for the total charge needs of your devices. For instance, if you have a mobile phone with a 1000mAh battery, then a power bank with a capacity of 3000mAh should be able to charge it at least twice, while a power bank with a capacity of 6000mAh will provide double that. Portable power packs measure their capacity in milliamps per hour (mAh), and the higher the figure, the larger the capacity. Start by checking the battery of the device you wish to charge.
