How to fast-charge your iPhone

Slow charging is an issue that iPhone users generally face. This problem is encountered by people using iPhones that came before the iPhone X.
Fast-charging the iPhone is possible. One method requires buying another Apple product like Apple USB-C to Lightning cable or any of the 18W, 29W, 30W, 61W, or 87W USB-C power adapters. But there are other workarounds that may help you in charging your iPhone at a fast rate. These methods employ the use of devices that do not require you to cough up money for another Apple device to charge your Apple iPhone relatively faster.
Using 2A power bank
Most of the power banks that are available in the market today come with multiple USB ports. Some of them come with 1A power output while there are others that provide 2A output. To charge your iPhone at a relatively faster rate, using a 2A power bank will help.
