//Adafruit 5V 1A Power Booster

Adafruit 5V 1A Power Booster

$14.99 USD

These amazing power boosters will take a voltage as low as 1.8V and output a clean 5V power supply.  We use these quite frequently.  Particularly, we use a single 3.7V 18650 battery and run the power through a power boost and then the 5V power out to our action cameras.  Additional pins allow you to programmatically turn on/off the output power and receive low battery signals.

  • Synchronous operation means you can disconnect the output completely by connecting the ENable pin to ground. This will completely turn off the output
  • 4A internal switch means you can get 1000mA+ from as low as 1.8V, 1500mA+ from 2 NiMH or Alkaline batteries, and at least 2000mA from a 3.7V LiPoly/LiIon battery or 3 NiMH/Alkalines. Just make sure your batteries can actually supply the required 2-4A, OK?
  • Low battery indicator LED lights up red when the voltage dips below 3.2V, optimized for the most common usage of LiPo/LiIon battery usage
  • On-board 1000mA charge-rate ‘Apple/iOS’ data resistors. Solder in the included USB connector and you can plug in any iPhone or iPod for a speedy 1000mA charge rate. Works with iPads, both mini and ‘classic’ type.
  • 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)
