How To Distingush Good Phone Charger

Now we will not let the phone run out of power, because many things are bound to our phone, the phone will be very inconvenient if there is no power, so every time when I go out with a dual-port charger, you can charge two phones at the same time. Or charge a mobile phone with a power bank , but buy a charger must buy good one, because this is not only to save money for myself but also for our own safety. How can the two-port charger be distinguished? The quality of a charger is mainly compared with materials and technology.

In terms of materials, we first talk about the outer casing. There are generally two materials of outer casing of the mobile phone charger, PC and ABS. The PC material has good flame resistance and high hardness. At the same time, the toughness is also strong, and has good insulation performance, and the price is relatively expensive; ABS material is relatively soft compared with PC material, flame resistance is not so good, hardness is little worse than PC material, so the price is lower.

Next is the pin of the dual-port mobile phone charger. The pins are divided into iron and copper. The iron is easy to rust. When used, the spark effect is fierce and the spark will be seen. The copper pins are heavy and the spark effect is relative mild, generally invisible. Finally,  the copper wire on the transformer inside the charger, good charger uses three layers of insulated wires, a bad charger usually uses a layer of insulated wire.

In terms of technology, let's first talk about compression molding. After the good pressure molding of the charger is cooled, the surface is smooth, and there is no clench or thorn in addition to the edges and corners. The compression molding technique is not good. There will be burrs on the surface of the charger and it will not be smooth. Finally, it is about safety insurance. There is always a safety barrier for good chargers. This is a guarantee for customers to use. It is indispensable for the safety of users. But there will always be unscrupulous manufacturers to cut corners for decreasing cost.
