Safety And Reliability Power Adapter

What is the difference between a high quality charger and a poor quality charger?

A genuine certified power supply and cottage charger compared to the price is often several times the difference, so what exactly is the difference between the two? Today the charger manufacturer for you to explain in detail it.

First of all, the components. A charger contains a transformer, capacitors, resistors, diodes, switching tubes, light-emitting diodes, heat sinks, voltage regulators and other components. High-quality chargers use big brand components, automatic patch, high performance, high temperature resistance, low loss, high current-carrying capacity, strong thermal stability. Poor quality charger components are easy to heat, unstable performance easy to fall off, poor conductivity.

Shell. The quality of the shell of the two is also a big difference, high-quality chargers using flame retardant materials, high temperature resistance, good heat dissipation, strong toughness, the appearance looks smooth and not rough. The poor quality charger in addition to the use of non-flame-retardant materials poor heat resistance, poor heat easy to damage, the appearance of rough not smooth.

Circuit board. High-quality charger using high temperature, flame retardant PCB printed circuit board, circuit design can protect components, reduce loss and heat, maximize the high conversion rate to ensure that there is also a role of voltage stabilization and current stabilization, while the low-quality charger using fiberglass PCB boards, thin plates, thickness is not up to standard, flammable and easy to break, circuit loss rate is high.

Power cord. High-quality chargers using national standard pure copper wire, plug flame retardant conductivity, 3C certification, low-quality chargers generally use ordinary non-standard wire, wire thin, easy to heat, charging the high temperature will melt the wire causing short circuit, spontaneous combustion or fire!

In addition to certified power supply and non-standard power supply in addition to the difference in the selection of materials and materials, the two power supply design is also a big difference, like many non-standard power supply due to the low cost of less material, naturally there will not be a short-circuit protection, overload protection, etc., this circuit protection design, and high-quality power supply products, in order to protect the consumer's safety will be designed to provide more protection, so we can find that a fire short-circuit charger occurred So we can find in the charger fire short-circuit accidents, more than ninety percent are caused by the use of poor quality chargers. Choose certified power supply, choose Eahunt, choose safety and reliability.
