Adafruit has launched a new addition to their range of electronics this week with the unveiling of the new Adafruit PowerBoost 1000C rechargeable 5V Lipo USB Boost that offers a rechargeable 5V Lipo USB Boost @ 1A – 1000C.
So if you are creating portable project and are looking for a small yet powerful feature rich power supply module and charger for a lithium battery, the PowerBoost 1000C might be the perfect component.
The Adafruit PowerBoost 1000C is equipped with a built-in load-sharing battery charger circuit, enabling you to keep your project running even while re-charging the attached battery.
The boost converter module can be used to powered by any 3.7V LiIon or LiPoly battery, and converts the battery output to 5.2V DC for running your 5V projects, says Adafruit who explains a little more:
“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.”
Features of the new Adafruit PowerBoost 1000C priced at $19.95 include :
– Synchronous operation means you can disconnect the output completely by connecting the ENable pin to ground. This will completely turn off the output
– 2A internal switch (~2.5A peak limiting) means you can get 1000mA+ from a 3.7V LiPoly/LiIon battery. 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 1000mA charge-rate ‘iOS’ data resistors. Solder in the USB connector and you can plug in any iPad, iPhone or iPod for 1000mA charge rate.
– 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)
