Principles of Ro-Charge Technology

Ro-Charge is different than competing fast-charging technologies that only increase charging voltage to achieve results. Ro-Charge controls the charging current, dynamically, to achieve its fast-charging performance while continuously monitoring the battery, adjusting the charging current every second. This provides a seamless synchronization between the charger and the battery.

Ro-Charge fast-charging technology offers advantages in charging speed, safety measures, heat dissipation, and more when compared with other charging technologies in the market. Ro-Charge delivers up to 20% more battery capacity during the first 5 minutes of charging, compared to the similar fast-charging technologies. And, Ro-Charge can charge approximately 83% of a 6000mAh battery in one hour! Typical fast-charging technologies achieve only 58%, and normal charging technologies only achieve 33%.
