The Micro USB interface is becoming increasingly popular among consumers due to its forward and backward insertion characteristics. However, there are still a large number of MicroUSB devices on the market, and the old devices in users' hands will not be phased out so quickly for a while. There is still a solution to achieve double-sided insertion. Guangjiayuan Electronics has launched an improved MicroUSB plug, which adopts a symmetrical hexagonal design and improves the plug terminals, This way, no matter which side is inserted into the device, it can be used normally. Can withstand a high current of 2.1A and support data transmission up to 480Mbps. The Type-C interface already has the feature of forward and backward insertion, and when paired with the newly designed MicroUSB interface, both ends of this adapter have the function of double-sided insertion. It can be used for ordinary MicroUSB phones and other devices, such as charging with Type-C data cables, reading data from Type-C USB drives, and so on. In the scorching summer, various heatstroke prevention and cooling tools have become popular, and these small fans that can be plugged into mobile phones work using their OTG output function. At present, the opening direction of the MicroUSB interface on some mobile phones and tablets is inconsistent, and the advantage of forward and backward insertion is evident. Regardless of the opening direction, it can smoothly insert and work towards the front of the device. The recommended reason is that the interface of ordinary MicroUSB data cables still needs to distinguish between positive and negative insertion. The spring in the middle of the interface of this coolsell (high view source) data cable adopts a double-sided gold-plated contact design, which not only has the characteristic of double-sided insertion but also greatly reduces the thickness of the interface terminal. About 1.2m long, it is suitable for mainstream MicroUSB devices including the Samsung Galaxy S6. The interface end and MicroUSB end of this data cable both have a double-sided plug design. The wire surface is made of environmentally friendly materials, with a smooth and tensile resistant feel. The socket terminals are made of aluminum alloy material. Supporting the USB2.0 data transmission specification, the MicroUSB end of this data cable also adopts a double-sided plug design, and the cable body adopts a noodle design, which is not easy to wrap and easy to manage. At the same time, it also has overcurrent, overvoltage, and short circuit protection. We have passed CE, FCC, ROHS and other certifications with guaranteed quality. Available in lengths of 1m/2m/3m, compatible with mainstream phone brands such as Samsung and HTC. The A port and MicroUSB port of this data cable both adopt a double-sided plug design. The conductive core is tinned copper wire, and the surface of the cable body is made of PVC material that reaches UL94V-0 flame retardant level. There are protective sleeves made of TPE rubber at both ends, reducing the damage caused by bending when inserting and unplugging the cable, and extending its service life. Available in lengths of 1m and 1.2m.
