VoltBase.
A modular charging station powered by power-tool batteries: 220V outlets, fast-charging ports, and a monitoring display for autonomy during blackouts.

I realized that people like me, who live in villages and towns, often have cordless power tools and their batteries, which in winter (when blackouts usually start) just sit around unused. So I decided to make an analog of a charging station, but instead of a regular battery, use batteries from power tools. Thanks to this, it will be possible to power devices during blackouts or use mains-powered tools far from an outlet.
How the VoltBase works.
You install from 1 to 4 batteries (depending on the configuration) and get access to 2 outlets, 1 USB port, and 1 Type-C port. There is also a display showing the charge percentage, current, and voltage.
