In electricity, a battery is a device consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy.

There are two types of batteries:

  • Primary batteries (disposable batteries), which are designed to be used once and discarded
  • Secondary batteries (rechargeable batteries), which are designed to be recharged and used multiple times. Batteries come in many sizes, from miniature cells used to power hearing aids and wristwatches to battery banks the size of rooms that provide standby power for telephone exchanges and computer data centers.

Will any external battery power a Raspberry Pi?

I am working on a project that needs the Raspberry Pi to work without a mains connection. I have considered buying a 50000mAh USB power bank. Would this power a Raspberry Pi, and if so, would it power it for more than 24 hours?
