The USB-C has been around for quite a while, but there is still a lack of a miniature basic USB-C chargers for LiPo battery. I decided to make my own with as minimal footprint as possible.
Meerkat Supercapacitor Charger is compact and versatile, designed to support common 2.5V and 2.7V EDLC supercapacitors. Wide input voltage ranges from 4.5 V to 16 V and adjustable Maximum Power Point provides the capability to use various power supplies, including solar panels. The charging current and end-of-charge voltage can be easily adjusted with a jumper.
