Eco-Friendly Mission

Each year, 10’s of millions of charging cables and power supplies are thrown into the garbage; thus, the reason why retailers ranging from gas stations to airport stores are able to resell the same accessories over and over.

Most of the models that we develop at myCharge have built-in accessories which eliminates needly e-waste. Eco is in the product’s very DNA. Walking the walk, not just talking the talk.

At myCharge we’ve eliminated all plastics from our packaging – down to the hangtag and sealing label.
