In our life, we often hear all kinds of safety accidents caused by improper charging of mobile phones, which are often attributed to "inferior charging heads" So how to judge the original charging head? Let's take a look at the true and false comparison of oppo charging head.

First, the product appearance comparison

Roughly speaking, there is not much difference between the two OPPO 30W chargers. They have the same appearance size, fixed pins and USB-A port output, and the OPPO logo is printed on the interface side. For consumers who don't often touch chargers, the shanzhai version is really confusing.

Second, the interface comparison

In terms of interface, the logo of the original OPPO genuine charger is smaller, the screen printing color is lighter, and the fake version logo is larger and darker, which has a feeling of floating on the surface of the shell. There is also a difference in the color of the rubber core between the two charger interfaces. Genuine color is pure, and the fake version is turquoise.

The genuine charger interface is internally designed with 5 pins, and the pins on both sides are widened.

The interior of the cottage interface is also designed with 5 pins, and the pins on both sides are widened, but the rubber core and pins are not very good in color and lack luster.

Third, OPPO genuine charging logo and pirated logo close-up.

Fourth, look at the charger labeling information.

Judging from the parameter marking information of the two chargers, the font of the genuine charger is thicker and the font of the cottage version is slightly smaller.

Five, the charger side sag contrast

The concave part on the side of the genuine charger has a smooth transition and a smooth feel.

The recessed part of the shanzhai charger feels obviously stepped and the mold is rough.

Comparison of product disassembly of intransitive verbs

Open the two charging shells respectively and take out the internal PCB board. Both chargers have built-in metal plates, but the metal plates of genuine chargers are used for heat dissipation, while the metal plates of shanzhai chargers mainly play the role of counterweight, so "more materials are used".

Authentic PCB components have compact layout, a large number of components, and a large number of glue injection treatments between components. The output end adopts custom interface and dustproof rubber sleeve design. The overall design of the cottage PCB is "very simple", and there are no traces of glue injection inside, which looks very "clean and tidy".

Glue is also injected into the back of the genuine PCB to assist heat dissipation, while the back of the cottage PCB is as clean and concise as ever.
