The Power Shield is the best way to provide power to your mobile Particle projects. Based around the MCP73871 battery management controller, this shield allows you to simultaneously power a Photon and charge a connected Li-Ion or Li-Po battery. You'll also be able to monitor battery levels using the Photon itself, which makes the Power Shield the best way to untether your wireless project.
Besides the on-board USB port, you can also use an external DC power supply or solar-cell to charge the battery. This shield ships with a 3.7V Li-Po battery and headers. Designed for use with the Photon, backwards compatible with the Core.
Operating Voltage: USB or External DC of 7 to 20V
Current Consumption: 500mA max (USB) & 1.2A max (other DC sources)
