Designed with the Earth in Mind

We created CHARGE as an eco-friendly alternative to the micro:bit Go pack because we saw the need to reduce the environmental and financial burden of disposable battery use in schools. We can do better.

For Example:

A district with 25 schools, each with a class set of 20 micro:bits and disposable battery packs, could spend over $5,000 annually on batteries and send 18,000 batteries into landfills every year.
