This has been the goal of the industry for years, and one big step toward it has been defining USB (Universal Serial Bus) ports. To put it simply, a power bank is a compact battery that has one or more USB ports. The USB port on your phone can also be used to charge it. In theory, this means that all power banks should be able to charge all phones.
Consider a Wireless Charger Option: For maximum convenience, many modern power banks now include Qi wireless charging. If your phone supports it, a power bank that doubles as a wireless charger eliminates the need for cables entirely, offering a simple and universal way to top up your battery on the go.
The circuit has two main functions: charge the power bank's battery when powered through micro USB and charge you phone in case of emergency. In my case I've just a single cell to replace but, in case your charger has more batteries, you only need more cells as the process is the same.
Typically, the power bank with more charge, like 50%, becomes the power Source. It will start topping up the other one with, let's say 20% battery left. If you try connecting two input-only ports, or an output-only port to another port marked "OUT," no current flows.
