Although the price is not necessarily proportional to the quality, but a penny. The price is high, the design, processing and materials of the product are naturally better, and the low price also naturally has the cost of stealing it. An experienced buyer will not over-price when negotiating with the supplier, because he knows the price that is forcibly pressed, and the result is likely to be a product that cuts corners. In addition to power supply products with many brand premiums like the Apple Power Adapter, the price of most regular manufacturers' power adapters is relatively transparent.
With the characteristics of the integrated power adapter product and the rules of the market, you know how to choose when purchasing the power adapter.

Inferior power adapters bring not only endless after-sales problems, poor consumer experience, but also unknown security risks. Therefore, the power adapter is more expensive, not bad.
