Before we delve into the specifics, let's start by understanding what a power bank actually is. Essentially, a power bank is a portable charger that stores electrical energy and allows you to recharge your electronic devices on the go. With a power bank in your bag or pocket, you can say goodbye to the anxiety of a drained battery.
Pass-through charging is another feature to consider; with it, you can charge your device and a portable power bank simultaneously. That's convenient if both your phone and backup battery are running on empty.
The number of times a power bank can charge your phone is determined by various factors, including the power bank's capacity and the battery capacity of your phone. To calculate the approximate number of charges, you must first know the capacity of both the power bank and the battery in your phone.
Modern power banks can charge a wide range of devices—not just smartphones. You can power up tablets, e-readers, Bluetooth headphones, smartwatches, portable speakers, cameras, and even some laptops. This versatility makes them an essential accessory for anyone with multiple gadgets.
