I thought they weren't working right at first.
Of course hook them up properly or you can burn them out...that wasn't the problem.
They were charging the battery great from all three ports in testing. But it wouldn't charge a phone. It was saying "out" but it wouldn't work.
The alligator clips weren't making enough contact through the teeth to move enough power.
Once I soldered decent wire between the board and the battery, it worked perfectly.

It works, kind of
I was going to make few power banks from 18650 I had laying around and came across these boards. They are pretty simple to use - just make sure that you connect it properly. Button works only to turn in on and off, nothing else. Charge current from a good power supply is around 1-1.5A. If you going to build big power bank with it (like 20000mAh) - it may take ~18-20 hours to fully charge it. Pros: - You can charge batteries with Mini USB, USB-C and Lightning cable. - Board detects charge / discharge. Cons: - What ever they say in specs about quick charge and 2.4A current is a total misinformation. Both USB outputs provide around 0.8-0.9A. Not even 1A. - Indication light is very bright and there no way to turn it off during charging (and I suspect it draws some extra juice from batteries as well). - It does not turn off by itself after charge is done (both ways when you charge it or charge with it). It turned off by itself only after I disconnected phone cable. If you ok with outlined issued it actually works. Just lower your expectations. Update: - Got it output 2A with the resistor load. Update 2: - It turns off display in a while after you start charging something with it; only "out" glows. - It displays 0% while batteries still are 3.65V which is quite weird. "Normal" healthy cut off voltage for most batteries is about 3.2V. It means that this board does not use about 40% of battery capacity OR indication is not correct. Update 3: - I just tried 2 more boards - first one got to 0% on 3.56V, but the second one displayed 13% left with the same battery. Very inconsistent.

My wife is the most laziest woman in this world who never wants to charge her phone in wall and keep asking me to plug it charge for her regardless i am busy or not... okay! Then i found this charger board to get my little project done for her. The most powerful power bank that could charger over 20 times of her phone and more than 10 times of her ipad. Thanks for the QC (quick charge circuit) + USB-C port that would charging the power bank quicker too.
Note:
Seller needs to correct the specs, maximum input: 3-4.2v. Typically that for lithium max voltage but it should be fine to use usb port 5V/2A input to charging the power bank which faster than microUSB 5v/1A. Depends on how many battery you have in parallel.

Got this product in the other day, and it is exactly what I was wanting. It is nice to have the multitude of ports that this product comes with. In the pictures, they do have the positive and negative terminals labeled wrong. Go with what is labeled on the board, and you will be good. The ports are a little tight when you first use them, but after that they work just fine. This was my first time soldering, and working with 18650 cells, and getting the board and bringing it all together was awesome. I am very pleased with my purchase, and would differently buy again.
