YoGenT Charger design and technical advantages:
For power capability and ergonomic design, for operation without fatigue and the most effective charging, three major design innovations have been incorporated:
1. A high power, disk alternator; designed as a very compact, low-profile device in a flat smooth housing. A novel, patented design of the combination of coreless permanent magnet rotor and stator coils, integrated with electronic circuit attached to mechanical transmission providing high power and efficiency of the charger .
2. For ease of use over extended periods of charging, the YoGenT mechanism is a masterpiece of mechanical engineering. To keep the unit flat, simple speed multiplication mechanism is designed instead of complex gear mechanism used in other hand chargers. Further, the alternator rotors are "flywheels", which with built-in ratchet extend the effective generation cycle even after the pulling cycle has ceased.
3. The YoGenT Charger high power capability is complemented by the innovative charging and protection circuit providing proper consumer (e.g. cell-phone) charging and monitoring SOC of internal battery.
Power needs and charging times:
Cellphones: typical talk-transmission power is about 0.5-1W. With the 3.7V lithium-ion batteries, discharge current can reach 130-270mA. Standby current is much lower and when the screen is off it is less than 10mA.
Most available cell-phone batteries are of 750-1300mAh capacity. Typical charging times, with wall chargers, are from 3 to 5 hours, providing up to 400mA. YoGen under intensive operation may supply up to 1 A and thus to provide a tenfold talk time in relative to cord pulling time.
