## 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.
