Chargie A - Finally A USB Charge Controller With Phone Programmable Charging Parameters

A simple in-line USB A charge controller. Set the parameters you want in the Android (and Apple in the near future) phone ap and then put in-line of the device you want to charge. I've heard that the standard charge Voltage termination is 4.35 on my Galaxy S10. With no Chargie device but with software running on the phone, I can see system Voltage and temp so I'll be able to reduce the "Charge Percentage" / Termination Voltage when I get the back ordered devices. It's nice to be able to back that down to 4.1 or whatever I want. There's a lot more settable parameters in the app. Download it and check it out. Each device is between $20 and $25 depending on how many you buy.

My Galaxy S10 at the moment of 100% charged = 4.334V
