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

The media could not be loaded. I used this for my piscore mini arcade project. I tried not to, and wasted a bunch of money because I didn't understand how awesome this is.The thing I learned (I started out with no knowlege on this, so far from an expert) is that battery charging requires a few things...you have to have protection to not overcharge the battery, it's ideal to have 'use while charging' (pass through), it's nice to have a way to switch the power on/off, and it's nice to be able to source enough power off of the batteries. Finally many batteries are at 3.7volts and I wnated something that I could output 5volts from.I tried quite a few different approaches to solve this, using parts from china off of various sites, and alternatives. I always ended up needing another part, and they never worked together well. Also having a way to turn the device fully on/off kept causing me problems...many of the solutions wouldn't do it effectively. I wanted to turn the power from the charging circuit to the game system off, but still be able to charge the system.This does ALL of that. It's super simple...you have a JST connector (two pin with a plastic connector (molex) that makes it easy to connect a battery). They also provide terminals as well. There are terminals for the load, and they have a place to put a 2 or 3 pin switch.Everything is documented very well on adafruits site. I"ve used adafruit stuff for ages, and they have always delivered a quality product. I love their stuff. I never doubted the quality of this, I just thought the price was high. After trying a bunch of differnet solutions, I realized the price of this is correct for having one small board do it all, and do it with quality.In the end, I should've started with this, I just didn't understand how many differnet common charging problems it solves. Most portable builds I see use this, and now I know why. In the end I think I blew 120 USD trying different solutions to beat this, and none of them came close. Great product.

Ordered two. Both released magic smoke in seconds after being plugged into usb. Do not recommend

This thing works great. There are a couple of things: If you don't want your voltage to drop as the battery levels drop (which causes the voltage that it puts OUT to drop...) hook up to the 5V pin. It's on a regulator, and I at least have gotten a nice, steady 5v from it whether it's plugged in or not. For another, it WILL get hot. This is a fairly small part. It runs at LEAST 1000mA when charging. It WILL get hot. Be prepared for that.Other than that, I don't think there's anything shocking. There are a lot of ways to hook this up, and a lot that can be done with it. Wire up a SPDT switch between Vs, EN, and Gnd, and you switch the supply on/off. For charging i-products, solder on the USB header that comes with it. It's chunky, so it's not soldered on for you automatically. Note this will NOT work if just placed. You're going to have to solder it. (Yes, this will charge iPads too)Do you need this? Well, if you're using bigger LiPoly batteries and you don't want them to take forever, then yeah, it'd be nice. If you want to run your project while charging the battery? Then yes. The load-balancing on this thing is great. If you just want to charge a 500mAh LiPoly? No, this is overkill, and will probably kill your battery.

This is a very thought out product. But I only have two vices with it. Just one amp output is not enough. Would like to have one that's at least 3 amps output @ 5 volts. Next is the tiny LED's on the board. Unless this to be an open air build, or mounted within acrylic. The leds are just useless. I have to remove the LED's from the board, wasn't easy. Run wires to some 3 mm leds of corresponding colors to the panel of what I was building. That process required a meter to find polarity of the leds, drawing a diagram to show color and polarity so I don't mess it up. and delicate soldering of small wires. Otherwise a well thought out product for a small niche of applications. Mine used for 5 volt bluetooth stereo speakers. No protection for batteries. It don't have over charge and under charge protection. So do use protected batteries. Unless you monitor the Leds, Things can go bad quickly. I initially bought this for a 5 volt class D amp board. It could not put out enough current to drive it. The switch set up is excellent.

This little board is a great piece for any techie. I was using this board for my first solder job and it was very easy to handle and work with. The simplicity for using this to make gadgets have portable power is just great.

I'm giving 3 starts because I have bought many of this board before and didn't have any issues with it. I bought two recently and both behaved very similarly: the output voltage would drop below 5V (less than 4.5V on occasions) just a few minutes after plugging it in. The circuit draws less than 40mA so this does not make any sense. It took me a week and testing every single component in my design to find the problem. It appears that others have experienced the same issue with modules ordered on Amazon, so I have decided to buy them directly from Adafruit from now on.

I've bought three of these puppies for various projects. They work very well, however, I did accidentally break one when I shorted the USB port on a Raspberry PI. A fuse or some sort of circuit protector might have been a nice addition but it's still a solid product!

I'm using this to power a Raspberry Pi Zero W in my vehicle. With the pinouts on this board, I can shutdown the Pi when the vehicle ignition is turned off and turn the Pi back on when the ignition is turned back on and not worry about brownouts.

Made a potato clock and and now I can recharge it with this, science! Thanks Bill Nye!

A great little device. Using it in a mini arcade hand held. Very easy to use. Some great guides online.

Pieza esecial para proyecto de gameboy con raspberry es un pequeño pero potente cargador de baterias lipo con amplificador del voltaje de la bateria de 3.7v a 5.13v con una corriente de pico maximo de 2.1A a parte de la salida principal tiene otras saidas para poner un interruptor de apagado y salidas de 5v en los laterales aguanta el tiron de arranque de la raspberry pi 3-b con una pantalla y amplificador de audio valido para crear un power bank para cargar movil tablet etc..

Ich war seit geraumer Zeit auf der Suche nach einem Modul, um mein Raspberry Pi Projekt mit einer USV ausstatten zu können. Ich habe einige Boards ausprobiert, u.a. mit TP4056 Chip oder auch ein anderes mit dem MCP73871 Chip, aber jedes hatte hier oder da einen Nachteil. Bei den TP4056 Boards hat aufgrund der konstanten Stromabnahme des Pi die Ladeschlusserkennung überhaupt nicht funktioniert, was die Akkus in kürzester Zeit zerstört, bei dem MCP73871 Board ist irgendwas mit der Schaltung völlig kaputt, denn das nimmt nie mehr als 0,2 A Eingangsstrom an und die anderen Boards haben Last- und Batterieanschluss direkt miteinander verbunden, was nie eine gute Idee ist.Der Powerboost 1000 C legt auf das ganze sogar noch eine Schippe drauf, da er einen 5 Volt Step-Up und eine Akkuladestandswarnung integriert hat, aber trotzdem sehr kompakt gebaut ist. Darüber hinaus erfüllt er das Pflichtprogramm, nämlich eine zuverlässige Ladeschlusserkennung, 1 A Ladestrom und er liefert genügend Strom für den Betrieb meines Raspberry Pi 3.Es handelt sich zweifellos um das Premiumprodukt am Markt für Stromversorgungs- und Akkulademodule, sowohl im Bezug auf Leistung als auch auf den Preis, aber es ist sein Geld wert.Einen Wunsch erfüllt das Modul nicht und das ist ein höherer Ausgangsstrom (insgesamt und im Akkubetrieb). Meine Akkus können deutlich mehr als 1 A liefern, leider nimmt das Board aber nie mehr Leistung ab. Vermutlich handelt es sich um eine Begrenzung im MCP Chip. Mit angeschlossener Netz- und Akkustromversorgung liefert das Board bei bisherigen Tests ca. 1,5 A, ich vermute aber das noch mehr geht und mein Pi nur nicht mehr abnimmt. Laut Datenblättern braucht ein Pi 3 bis zu 2,5 A, das Board liefert jedoch maximal ~ 1,8 A. Soweit meine Recherchen bisher ergeben haben, gibt es kein Board das alle meine Wünsche erfüllt, aber der Powerboost 1000 C ist am nächsten dran und damit zum Mittel der Wahl geworden. (Kein Punktabzug dafür, da es lediglich ein Wunsch von mir ist und kein Mangel am Produkt)
