The Energo Pro Charger emerged from the collective efforts of our team at Energo, comprised of individuals with extensive backgrounds in electronics and sales. Identifying a recurring issue in the market, we observed a growing prevalence of conventional phone chargers succumbing to premature deterioration, compromising both their quality and efficiency. Additionally, the reliance on cables for power bank functionality presented limitations in portability and convenience. In response, we endeavored to develop a solution: a compact, cable-free portable charger tailored for on-the-go use. Thus, the Energo Pro Charger was born, offering unparalleled convenience in a form factor small enough to be conveniently carried on a keychain.
