Review: Board to build 1-cell USB power bank. Good assembly quality, shielded SMD inductor. - This board uses FM5324 battery management and boost voltage regulator chip, has good assembly quality and does what is expected. SMD shielded inductor is a plus. The board has charge gage. On the minus side, the board behaves as other power bank supplies: it detects load current and if the current is below 80mA, it turns off the regulator. The current threshold is set in the chip and cannot be changed, and automatic shutdown cannot be disabled.
Review: Does as it says, but with slight modification. - This works as intended and will charge my 21700 battery (slighter larger than an 18650). It has LED's which will indicate if it is charging and also display charge level. The problem is that once you solder the battery to the board there is no way to turn off from the LEDS or the board so it will eventually drain the battery. This was easily fixed by adding a normally open push button between the battery input and the 5v output

## Features

- ❃❃10PCS ( no welding version) Type-C USB 5V 2A Boost Converter Step-Up Power Module Lithium Battery Charging Protection Board LED Display USB For DIY Charger
- ❃❃USB is no welding version
- ❃❃It supports the external key, which is connected to the K point and the output negative pole. Short press to turn on the power display and turn on the 5V output. Two consecutive short presses will turn off the power display and turn off the 5V output.
- ❃❃When the load current is less than 50mA continuously, the output will be turned off.
- ❃❃1; When the charging current drops to 100mA after reaching the final floating charging voltage, the charging cycle will be automatically terminated; 2; When the battery voltage drops below 4.1V, the charging cycle starts again. 3; When the battery voltage is lower than 2.8V, the battery will be pre charged with a current of 180mA.

## Questions & Answers

**Q: Can it charge the battery from the usb-c while also outputting 5v on the usb-a ?**
A: Yes, it can

**Q: After unplugging the usbc power, blue leds continue to all blink , every 10-20 seconds or so for about two minutes.. What is this telling me?**
A: From my experience something is wrong with the battery I connected the battery reversed to see what it would do and the LEDs started blinking like you described

**Q: Is this what i need to convert a device that takes 2 AA batteries over to using an internal lithium battery? Does this have overcharging protection?**
A: Not quite. Yes it will charge a lithium battery safely, with a 4.2v float voltage (works with standard 3.7v nominal lithium ion or lithium poly cells) but the output is boosted to 5v for the load side. 2xAA devices usually want 3v.

You could pair this with a 3v LDO module to drop the output to the voltage you need, though, but really you want a plain charger (no boost) and a 3v LDO as this will be more efficient

**Q: Do the leds turn off on their own? i don't want them draining the battery.**
A: They come on when connected to a charger and turn off soon after disconnected.

### ⭐⭐⭐⭐⭐ Board to build 1-cell USB power bank. Good assembly quality, shielded SMD inductor.
*by D***M on July 15, 2023*

### ⭐⭐⭐⭐⭐ Does as it says, but with slight modification.

### ⭐⭐⭐⭐ Okay as a charger
*by K***R on November 8, 2025*

Update: Change from 2 to 4, because I found a flaw in one of my circuits. Basically an induced reverse current that I failed to see in testing. I don't want to burn up another device so I'm not going to verify as I only have a couple left, but I'm pretty sure my circuit flaw was the cause of my issue with the module. The module is okay as a charger (18650 battery). I'm not sure if my issue with the module is a bad circuit design on my part, but 3 of them burned up after applying a load with less than 1A current draw. I measured the load so am sure about the power draw. I'll use the remaining only for charging, as I don't trust the boost converter to provide 5V without worrying about a possible fire caused by a failed module.
