PowerBoost 1000 Charger - Rechargeable 5V Lipo USB Boost @ 1A -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
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
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 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, we 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 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. This one from Adafruit is ideal and has been tested, 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 1.8A.
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, pick up a 3.5mm 2pin block here and solder to the output spot where the USB jack would go. Or dont solder anything in for a more compact power pack.

Nice for the lips
It is very nice. Second time because it lasts all day!

Nice product
The lip balm feels great, love the “flavor”, but I have to apply it just as often as any other chapstick! And my lips still get dry!

Good but goopy
It's has an amazing taste (think Cinnamon Toast Crunch!), my boyfriend always loves to give me a kiss after I put it on. It's amazing that it's beeswax and tallow, love that. Love that it's a wide size, those are the bet types of chapstick. However.... it's just goopy all the time. It doesnt stay on your lips for that long, either.

Moisturized lips for a great price
Keeps my lips moisturized. Sometimes get a tingling feeling and but be from the cinnamon. I do like the smell. Will first feel kind of greasy so you don’t need much but after a few hours the greasy feeling goes away and you just have moisturized lips. There’s a lot in the tube so will probably last a while.
