Anker PowerLine II Dura 10' | $10 | Amazon | Promo code ANKER434

With its incredibly durable construction and lifetime warranty, Anker’s PowerLine II Dura might be the last Lightning cable you ever have to buy. For a limited time, you can get the 10' model (in all four colors) for just $10, or about $5 less than usual. I have one of these running behind my couch, and it offers tons of slack so I can lounge while I charge, and it’s tough enough to be repeatedly eaten by the Roomba with no repercussions. Five stars would recommend.
