This charger is the only one you need to keep all your Lithium Polymer (LiPoly) or Lithium Ion (LiIon) rechargeable batteries topped up. No matter the power source at your disposal! The Adafruit Universal USB / DC / Solar Lithium Ion/Polymer Charger can use USB, DC or Solar power, with a wide 5-10V input voltage range! The charger chip is super smart, and will reduce the current draw if the input voltage starts to dip under 4.5V, making it a perfect near-MPPT solar charger that you can use with a wide range of panels.
Even though Adafruit designed it with solar in mind, it's also great as a plain USB or DC charger - Adafruit like that you can use 5V or 9V chargers without worry, and the high charge rate is great for quickly charging up those large battery packs!
Compared to Adafruit's earlier, MCP73871-based charger this universal charger has some nice improvements:
However...
This charger is a breeze to use for solar projects: pick up any of Adafruit's many 3.7V/4.2V LiIon batteries, and a 6V solar panel. Plug the battery into the BATT port using a 2-pin JST cable and the solar panel into the DC jack using a 2.1mm adapter cable Put the solar panel outside (and keep the battery out of the sun, it needs to be kept cool!) to start charging. You can power another project at the same time by connecting to the LOAD output port, which will never go above 4.4V.
The bq24074 which powers this design is great for solar charging, and will automatically draw the most current possible from the panel in any light condition Even thought it isn't a 'true' MPPT (max power point tracker), it has near-identical performance without the additional cost of a buck-converter. Adafruit's detailed tutorial on how to use this charger includes a design document explaining how it all works.
For use with Adafruit Lipoly/LiIon batteries only! Other batteries may have different voltage, chemistry, polarity or pinout.
Comes with an assembled charger board, and bit of header. Does not come with a Lipoly battery or solar panel but we do have tons available in the shop that work quite well.
