Description

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.

To make this even more useful, Adafruit added a MicroLipo charger on the other side. The charger circuitry is powered from a microUSB jack, and will recharge any 3.7V/4.2V LiIon or LiPoly battery at 500mA max rate. There's two LEDs for monitoring the charge rate, a yellow one tells you its working, a green one lights up when its done. You can charge and boost at the same time no problem, without any interruption on the output so its fine for use as a "UPS" (un-interruptable power supply) for a low-current draw device. Just be aware that the charge rate is 500mA max, so if you're drawing more than ~300mA continuously from the 5V output side, the battery will slowly drain since the charge rate is less than the dis-charge rate.

Each order comes with a fully assembled and tested PowerBoost 500C + USB jack. Does not come with a Lipoly or LiIon battery, but we do carry one in the shop perfect for your battery needs. Also doesn't come with the nice iPhone or charger cable. 

If you're trying to figure out how much current your project is using, check out the Charge Doctor

  • Synchronous operation means you can disconnect the output completely
  • 2A internal switch (~2.5A peak limiting) means you can get 500mA+ from a 3.7V LiPoly/LiIon battery. 
  • Low battery indicator LED lights up red when the voltage dips below 3.2V
  • 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 (see datasheet for efficiency graphs), and low quiescent current: 5mA when enabled and power LED is on, 20uA when disabled (power and low batt LED are off)
  • Dimensions: 22mm x 37mm x 2mm / 0.9" x 1.5" x 0.08"
  • Height w/ JST: 7mm / 0.3"
  • Weight: 4g
