If you often forget to carry your backup battery when you need it most, consider a dedicated battery case instead. These cases combine the portability and protection of a case with additional battery capacity to keep your phone topped off at all times. There are several drawbacks. First, they have limited additional. .
These days, "small" portable batteries have a capacity of around 5,000mAh, which means they easily fit into your pocket and still have. .
Generally speaking, you charge the battery itself via USB-C (input). Speeds differ depending on the battery you choose. Many batteries also still include a standard USB-A port (output). This is for plugging in USB-A-to-Lightning or USB-A-to-USB-C cables for. .
Another factor to consider is how quickly a power bank can charge your device. Battery output is measured in voltage and amperage. Amperage (or current) is the amount of electricity. .
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. You shouldn't encounter any safety. [pdf]
