Mobile devices from the turn of the century had incredible battery power. Any Nokia or Motorola device could go uncharged for about a week and then still have 60% battery life left. But their staying power was largely due to their inferior technology when compared to today’s mobile devices.
While the latest iPhone or Samsung Galaxy needs to be charged at least once a day, they also have more computing power than it took to send humans to the moon. Functions such as Wi-Fi, Bluetooth, mobile data, location tracking and powerful cameras can make short work of the battery. If you’re having a busy day and can’t get to a wall socket, the best option is to get a portable charger to keep your phone going.
The physical size of the portable charger (also called a power bank) isn’t as important as what is inside. The capacity determines how much electricity is stored in the charger, and therefore how many devices you can power up or how many times you can recharge a single phone.
A portable charger’s capacity is measured in milliampere-hours, the same measurement used by mobile device makers. For example, the iPhone 13 has an internal battery with a capacity of 3,227 mAh, while the Samsung Galaxy S21 Ultra has a 5,000 mAh battery.
So, simple math can be used to determine if a portable battery’s capacity is sufficient for your needs. A portable charger with a 20,000 mAh capacity can fully recharge the Samsung Galaxy S21 Ultra four times, while it can charge the iPhone 13 about six times.
