This little black box charges single-cell lithium polymer batteries with a max rate of 1A. Apply regulated 5V DC input voltage. The charge output is via a 2-pin screw terminal. Top pin is ground, bottom pin is charge pin. Based on the popular Microchip Lithium Polymer charger IC MCP73843-410.
Note: Supplying over 5V is not recommended. Although the the MCP73843 datasheet states that you can supply up to 12V, users have reported destroying this charger even when applying a regulated 7V. Our universal regulated supplies listed below can supply 4.5V, which is the minimum power required by the MCP73843, but at a current of over 1A.
The power connector is a 5.5 × 2.1 mm center-positive barrel.
