What does 7800 mAh mean for a phone power bank charger?

Phone batteries and power banks tend to be rated by capacity usually denoted by mAh.

mAh stands for milliampere-hour or milliamp-hour, depending on where you are from. It is 1000th of an ampere hour (amp hour or Ah) which, simply put, is a measure of the unit of electric charge that can be delivered over time. It describes total amount of electric flow a battery can provide over time or can store at a given time. Yours can store and deliver 7800 milliamp-hour charge over time (one hour).

Note that not all power banks deliver the capacity they claim.
