Smart devices are developing day by day, but inconvenience of turning them on to check charging status still exists. Thus, I will propose new charging cable which allows users to check charging status intuitively without turning devices on. Check’n Cable not only shows charging level on display of the cable body to remove necessity of turning smart devices on, but also changes display color according to charging level, so that users recognize intuitively. Charging level is displayed with LED, so that it can be easily found with bare eyes in a dark circumstance.
