Charger Model: 21429783 Of course in reality, not all places have a pile of building charging Charging machine suppliers, some charging charger wholesale demand, but suffer from not charge users, the need to address them by what means ? American company called FreeWire Technologies company gives a solution turbine charger factory, they developed a vehicle charging and energy storage set in one mobile charger, charge every day to meet the needs of electric vehicles 5-8, with portable and scalable characteristics, which in fact did not place too much innovation, nothing similar to the phone's charging treasure features, but Americans are still walking in front of us. Charger Model: 3634778 Features frequency machine is simple, there is a problem big a) the size of the input and output transformers; 2) for the elimination of large high harmonic output filter size; 3) transformers and inductors produce audible noise ; charging machine (6) 4) poor load and mains changing dynamic response performance 5) low efficiency; 6) Input no power factor correction, power grid more polluting; high 7) costs, especially for small capacity models, can not be compared with the high-frequency machine charging machine suppliers, faithful electromechanical (certified), charger provided by the Dongguan City, South City Zhongxin Electrical and Mechanical Services Department.
