Thanks to their durable construction I have no doubt that you can bend these cables over 5000 times as Anker claims. Using an inline volt meter I was able to test these cables up to 2.5A of draw, even with the 10ft cable. Included with the three pack are three cables at 3ft, 6ft, and 10ft lengths as well as three Velcro cable ties.
If you own an iOS device that utilizes a Lightning connector, I highly recommend this three pack. They are built to lost, charge fast, and having all three lengths available is extremely convenient.
If you are interested in purchasing these cables, they can be found here.
