iPhone 4s charging cable fake or real?

Hello community, recently my charging / data cable got a defect so I bought a new one via ebay. It is stated that it's a new and original Apple product, just without original case. However, I found out that there are a lot copies out there. Now I'm worried that I'm using a fake copy that might damage my beloved old iPhone 4s that I like to take with me when I need something small but want to be reachable. On the Apple site it is only an explanation for a lightning cable [ https://support.apple.com/de-de/HT204566 ] and a video which has only a comparison between a lightning cable and a 30pol cable (for iPhone 4sm iPad.. etc.) [ https://www.youtube.com/watch?v=ETo1LC7NH1A ] the cable I have as exactly the same specification like the ones in the video. the printed label is closer to the USB , the writing is from left side "Designed by Apple Made in China" ( no serial no.) and not from right side and further away. Is there a way to tell that this is a fake or original? The material on the USB does look cheaper than it should. Unfortunately I do not have my old cable to compare since I threw it away. :c
