Within hours of my comments I was contacted by Anker customer support and assured that it would not damage either the face or cable and was even offered two replacement cables. In addition, they asked if I preferred any other solution and offered to ship the cables out immediately. Superb customer service as the product has not failed and the company has taken a proactive position. I have also purchased five of their 40W 5-outlet usb chargers for home business and gifts and found them excellent. Great products from a company with great customer service. BTW. I have decided to decline their generous offer as I believe that they are correct that this will not cause any problems to the housing or the cable and feel reassured by their email that if a problem does arise that they will remedy it as they have an 18 month warranty.
It's rare that I would say unboxing an item is a great experience. The exceptions I've had are usually Apple products. But you can tell Anker put some thought into how this item was packaged. The battery itself is solid and well made. It has some weight to it for sure, but feels nice in your hand. Very sturdy and in no way "cheap". A nice touch is that it includes a drawstring bag/sleeve to protect the battery in your bag or wherever you carry it. Operation is simple. Charge the battery with the supplied micro USB cable. A full charge will take several hours so prepare accordingly if going on a trip. Shake the battery to confirm power (in 10% increments). The LED indicators are easy to read and VERY accurate. You can simultaneously charge up to three devices. Plug them in, give another shake to begin, and they're charging. I've found that my phone and iPad charge at about the same speed as they do when plugged into an outlet. I can get some combo of 3-4 charges out of both before this battery is exhausted.
I would not hesitate to recommend this product to anyone. And, based on my experience, I would also recommend any other Anker battery product. When the time comes I will definitely be purchasing another to replace this pack.
I hope this review was helpful to you. If you have any questions, please post them in the comments and I'll be glad to reply.
