What is the difference between high-quality chargers and low-quality chargers?

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.05.12
What is the difference between a certified genuine charging place and a low-quality charger, as their prices often differ by several times? Today, the manufacturer of Kinri Energy chargers will give you a detailed explanation.


240W Sealed Battery Charger

Firstly, the components. A charger contains components such as a transformer, electrolytic capacitor, resistor, diode, switch tube, light-emitting diode, heat sink, voltage regulator, etc. The high-quality charger uses components from major brands, which are automatically mounted, have high performance, high temperature resistance, low loss, high current carrying capacity, and strong thermal stability. The components of the charger are prone to heat generation, unstable performance, and easy detachment, resulting in poor conductivity.

Shell. The quality of the shell also differs greatly between the two. High quality chargers use flame-retardant materials, which are resistant to high temperatures, have good heat dissipation, and have strong toughness. The appearance looks smooth and not rough. Poor quality chargers, in addition to using non flame retardant materials, have poor heat resistance, are prone to damage, and have a rough and unsmooth appearance.

Circuit board. High quality chargers use PCB printed circuit boards that are resistant to high temperatures and flame retardancy. The circuit design can protect components, reduce losses and heat generation, maximize high conversion rates, and also have the function of stabilizing voltage and current. On the other hand, low-quality chargers use fiberglass PCB boards, which are thin and not up to standard in thickness, flammable and easy to break, and have a high circuit loss rate.

Power cord. The high-quality charger adopts national standard pure copper wire, and the plug has good flame retardant and conductivity performance, with relevant authoritative certification. Poor quality chargers generally use non-standard wires, which are thin and easy to heat. The high temperature generated by charging may melt the wires, causing short circuits, spontaneous combustion, or fire.

In addition, certified power supplies and non-standard power supplies not only have differences in material selection, but also have significant differences in their power supply designs. Some non-standard power supplies, due to their low cost and limited use of materials, even lack short-circuit protection, overload protection, and other protective circuit designs. High quality power products, for the safety of consumers, will be designed with more protective measures. Therefore, we can find that more than 90% of accidents caused by short circuits and fires in chargers are caused by the use of inferior chargers. A high-quality power adapter manufacturer can confidently choose Kinri Energy.
