QC-MINI QC 2.0/3.0 USB fast charging board sells for $2

QC-MINI is a USB fast charging board that can take 6V to 32V DC input from a power source such as solar panel, and outputs 3 to 12V via a USB port using QC 2.0/3.0 and other fast charging standards.

The board can be useful to implement fast charging in any project, and it won’t break the bank as I’ve just come accross the module on IC Station for just $1.99.

QC 3.0 charging module

Typical applications would include solar panel to mobile phone charging, car charging retrofit, driving recorder power supply, and “household power supply transformation”. The $2 price tag initially looked really inexpensive to me, but afer looking for QC-MINI on Aliexpress, I failed to find the board there, but realized QC 3.0 car chargers – for example – are equally cheap going for less than $3 shipped. It remains to be seen whether those cheap QC 3.0 hardware platform do work as advertised.
