At first glance, these chargers seemed durable, after a week when plugged into a phone jack, the first chord literally broke. I dismissed it as a broken wire. I used a second 10ft cable and within 3 days of unplugging the connector the connector broke and got stuck in my tablet. On the third wire, which is bent again at the connection point and does not charge. I would like to return but I threw away the 1st wire. Don't waste money.
