Data lines that can be recharged at any time

With the rapid economic development, the development of science and technology is also changing with each passing day. Nowadays, most of us use smart phones, and smart phones always consume fast power, so carrying data cables with them is very important for smart phone users. For example, when traveling, you can charge your smartphone at any time with your laptop or mobile power. But what if you come across a user who is prone to losing it or is not accustomed to carrying a data cable? At this time, the USB key-shaped data cable will come into full play.

Recently, an ultra-portable data cable called ChargeKey came out. The two ends of the data line are USB interface and Lighting or micro-USB interface respectively. Most particularly, this data cable is also equipped with a curved key-shaped “cable” that can be conveniently placed on the key ring and carried extremely easily. Whenever you want to synchronize your data or charge your smartphone, you can use it anywhere, anytime.

The cost of this ChargeKey is 29 US dollars (about 180 yuan), the price is almost the same with Apple's Lighting interface data line. The device is also officially certified by Apple and can be used on any iOS device. Of course, users can also use the version of the micro-USB interface, which is compatible with any device, not just a smartphone.

It is believed that for most consumers, the most convenient for this ChargeKey device is its excellent portability. No matter what kind of "cockroaches" it passes in your pocket, as long as it is still on your key ring, ChargeKey will not lose it.

In order to improve the portability of such devices, manufacturers can do what they are used to. In addition to the ChargeKey with a key cable, there is a ChargeCard like a ChargeCard. This USB cable is the same size as a credit card, so that the user can place it in the wallet like a credit card, ensuring that it will not be lost.
