Green Tech industry has participated in the project for the development of power supply device requiring no battery for the first time worldwide to succeed in the massive production, which is environmental-friendly as well as economical.Using the power supply device, we are specialized in massive production of the remote controls for TV, VCR, SAT, CATV, DVD, communications unit and various kind of automatic remote control systems to supply for the domestic as well as overseas markets.Normally, remote control requires a battery as a main power.Recently, a battery without mercury or cadmium is materialized in use since the existing battery causes damage to the environment and the soil when waste batteries are disposed of in, but it is not considered as a proprietory and fundamental measure. That&＃39;s because not only does it cost a great deal due to separate disposal but polluted materials are discharged during manufacturing process.To solve this problem, we combine power generator with charging circuit to insert into the body of remote control so that no recharging battery is required for charging circuit.Our product is to replace batteries used in remote control, so it is environmental-friendly and requires no battery, ensuring economical effect, diminishing trouble factors such as removal or damage of battery cover due to nonexistence of battery cover, and semi-permanent use.
