PowerBoost 1000 Charger - Rechargeable 5V Lipo USB Boost @ 1A - 1000C

by Adafruit

PowerBoost 1000C is the perfect power supply for your portable project!

With a built-in load-sharing battery charger circuit, you'll be able to keep your power-hungry 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 dont need the 1A battery charger, smart load-sharing, or 1A iOS resistors, check out the Powerboost 500C

Adafruit 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 1000C 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 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)

To make this even more useful, they stuck a smart load-sharing Lipoly 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 1000mA 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.

Since the built-in battery charger has load-sharing, it will automatically switch over to the USB power at the Micro USB input when available, instead of continuously charging/draining the battery. This is more efficient, and lets you charge-and-boost at the same time without any interruption on the output so its fine for use as a "UPS" (un-interruptable power supply).

Just be aware that the charge rate is 1000mA max, and there's some inefficiency during the boosting stage, so make super sure that the USB adapter you're using to charge with is high quality, can supply 2A and has thick power wires. Lower quality ones will not act well due to the voltage drop on the wires or droop on the power supply. This is especially true if you're actually drawing 1000mA out of the PowerBoost 1000C, the MCP73871 maxes out at 1.8AYou do have to always have a LiPo plugged into manage the load spikes, it's not optional!

This charger-booster is great for powering your robot, Arduino project, single-board-computer such as Raspberry Pi or BeagleBone! Each order comes with one fully assembled and tested PCB and a loose USB A jack. If you are powering your project from USB, solder the USB A jack in (a 3-minute soldering task). If you would like to use a terminal block, solder a 3.5mm 2pin block to the output spot where the USB jack would go. Or dont solder anything in for a more compact power pack.

Awesome case. Simple to put together, protects well and great value.

so far i'm loving this case, i did try to fit the pi0-2w into my pi0 case and i had to break a piece off the case - much better to get a case designed for the pi0-2w. It has a nice set colours and it shows the pi0-2w in all it's tiny/funcional glory

Didn't read description so surprised about assembly required but ready to put together.

Nice quality with clear instructions. It was pretty easy to get the protective film off and the addition of a thin shim makes the board sit even nicer than in the original Pibow

Quality little case. And it's purple. What more do you need? Well, easy access to the SD card but other than that it's all good.

It's a little fiddly to get together, but it's a very cute case, and it does the job perfect!

Nice little enclosure to keep the Zero out of "shorting range" of other stuff on your desk ;)

It's a case for the Pi Zero 2 W. Like all the Pibow cases - well designed and made. Nothing more to say other than efficient and fast shipping from a reliable supplier.

Fits the Zero perfectly, would be even better if you could access the SD card, however you still gain full access to the GPIO pins, which is a massive plus

Everything is fine, just waiting for a Pi Zero 2 W to come into stock

An excellent, colourful way to protect your Pi Zero 2. Very easy to construct. You do need to take it apart to replace the micro SD card, but that doesn't take long.

Works great, assembly makes sense if you check the website first for instructions!

Great new pibow. With blue and indigo. I really like this pi zerow2 case. I have the 1.2 pi zero bloue pibow; the pibow pi zero 1.3 camera accommodating orange case case and now this beautiful indigo & blue one. These look great!
