A BATTERY CHARGER, or recharger, is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it.

The charging protocol (how much voltage or current for how long, and what to do when charging is complete, for instance) depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging (i.e., continued charging after the battery has been fully charged) and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type. Simple chargers of this type must be manually disconnected at the end of the charge cycle, and some battery types absolutely require, or may use a timer, to cut off charging current at some fixed time, approximately when charging is complete. Other battery types cannot withstand over-charging, being damaged (reduced capacity, reduced lifetime), over heating or even exploding. The charger may have temperature or voltage sensing circuits and a microprocessor controller to safely adjust the charging current and voltage, determine the state of charge, and cut off at the end of charge.

Slow battery chargers may take several hours to complete a charge. High-rate chargers may restore most capacity much faster, but high rate chargers can be more than some battery types can tolerate. Such batteries require active monitoring of the battery to protect it from overcharging.

A POWER BANK is a portable device that can supply power from its built-in battery through a USB port. Power banks are popular for charging USB charged devices. They can also be used as a power supply for various USB powered devices such as lights and small fans. They usually recharge with a USB power supply. The power bank includes a control circuit that both regulates charging of the battery and converts the battery voltage to 5.0 volts for the USB port. Some chargers for cells like 18650s and 26650 can also serve as a power bank. Although it is generally more cumbersome to carry such a charger with cells rather than a conventional power bank, this type of setup has the advantage of being able to charge cells for other uses. It also has the advantage that, when the cells are dead, they can be swapped for fresh cells for immediate use rather than having to be recharged first.
