Lithium polymer charger - noob question

by Maineiac on Thu Jun 04, 2020 6:27 pm

Hi all. I'm new to the Ardafruit world and I have a very basic question. I have an Ardafruit Lithium Ion Polymer Battery - 3.7v 500mAh (https://www.adafruit.com/product/1578) and I need a way to charge it, if possible, from a USB wall plug, like those used to charge cell phones. I've been looking at the mini lipo chargers and the micro USB charger (#1304). The micro USB chargers looks neat, but will that work in a wall cube charger? This battery is powering 12 x 12V max 3 mm LEDs. I'm also open to advice if I've miscalculated something. Thank you!

Yes. You can power them from a USB wall plug style phone charger.

This battery is powering 12 x 12V max 3 mm LEDs.

Do you have a voltage boost converter? LEDs designed for 12v are not likely to work with just a 3.7v battery.

Thank you! I guess my forum searches missed this answer. Much appreciated.
