General power adapter wholesale is to get goods from the power supply manufacturers, and then sold in Taobao or exported to foreign countries. Open Taobao Mall, search for mobile phone chargers, you find many unknown "brand" chargers, and the price is still very affordable, many 10W power adapters, the price is not more than 10 yuan. So these merchants got so many cheap goods from there? Is there any guarantee for quality?
Why are the same power adapters, some sell dozens of pieces, and some sell a few pieces, how big the industry is, how many people are curious about these problems, in fact, not as complicated as you think.
You see that some brand chargers such as Apple Samsung sell very expensive, but in fact, the profits of the companies that produce them for OEM are not high. Most of them are brand premium and quality assurance. Although the price is not high, but you still have to admit that the quality of the Apple charger is really good, whether it is the material welding of the shell, or the selection of internal components and circuit design is first-class.
Most of the "cheap" power adapters on Taobao come from small factories that are not certified, do non-standard power supplies, and some from the second-hand market. The price is cheap, the material is naturally discounted, and all aspects can save the province. If you can use it, it is ok. But when you can use it, you won't get angry, it will damage your equipment, or even explode.
There are expensive reasons, cheap and cheap. A penny of goods, in addition to Apple and other brand chargers, most of the production power manufacturers' profits are very low, there may not be a high profit after the wholesale of the power adapter wholesale. In particular, resistance, capacitors and other materials are seriously out of stock. In the case of price increases, many small power plants are unable to support them. Shenzhen Intermodal Electronics still adheres to military quality and escorts electricity for millions of consumers. It is worthy of praise.
