I had been wanting to get this and when it went on sale, I jumped on the offer. It’s a great add-on, extends the time of use. I’ve only used it once and that was just to test it and everything worked great and charging it was fast.

Anker customer service is top notch quality and their products are among the best available. I reached out to their customer service team on a couple of occasions and received responses within the hour. Next purchase, I'll bypass Amazon, and order directly from Anker.
