Adafruit PowerBoost 500 Charger - Rechargeable 5V Lipo USB Boost @ 500mA+ [ADA1944]

Regular price $24.02 Sale

PowerBoost 500C is the perfect power supply for your portable project! With a built-in battery charger circuit, you'll be able to keep your project running even while recharging the battery! This little DC/DC boost converter module can be powered by any 3.7V LiIon/LiPoly battery, and convert the battery output to 5.2V DC for running your 5V projects.

If you need a 1A battery charger, smart load-sharing, and 1A iOS resistors, check out the Powerboost 1000C

Like our popular 5V 1A USB wall adapter , we tweaked the output to be 5.2V instead of a straight-up 5.0V so that there's a little bit of 'headroom' for long cables, high draw, the addition of a diode on the output if you wish, etc. The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB cable resistance.

The PowerBoost 500C has at the heart a TPS61090 boost converter from TI . This boost converter chip has some really nice extras such as low battery detection, 2A internal switch, synchronous conversion, excellent efficiency, and 700KHz high-frequency operation. Check out these specs!

  • Synchronous operation means you can disconnect the output completely by connecting theENable pin to ground. This will completely turn off the output
  • 2A internal switch (~2.5A peak limiting) means you can get500mA+from a 3.7V LiPoly/LiIon battery.We had no problem drawing 1000mA, just make sure your battery can handle it!
  • Low battery indicator LED lights up red when the voltage dips below 3.2V, optimized for LiPo/LiIon battery usage
  • Onboard 500mA charge-rate 'iOS' data resistors. Solder in the USB connector and you can plug in any iPhone or iPod for 500mA charge rate. Not suggested for large iPads.
  • Full breakout for battery in, control pins and power out
  • 90%+ operating efficiency in most cases (
