    I have three of these, I have to use these in my line of work where I travel and sometimes don't have power for a couple of days. Charges quick and it's reliable. Recommend getting the Anker charging cables also to get fast charges to your phones and other gadgets. Although avoid Anker nylon cables. Had bad experiences with them. I get their regular cables. That's all I buy now.

    I love anker products, they are really good. I was looking for a portable charger to carry with me for my long runs. Love that it can recharge iphone7 close to 6 times. Very usually for longer travel time too.

    This was recommended to me by one of the Best Buy employees, he said that this is the one he uses. He was right! Took a trip to Disneyland with the family was able to charge my phone which was almost depleted each day the 2 kids phones and the wife’s phone and still had a lot of power in the charger. At the end of each day. (All iPhones. 2 Xs Max and 2 iPhone 7’s)

    I purchased this charger since my phone battery always go low when i use the camera for a long period of time on my trips and this is the best portable charger by far for the price and ability to fast charge 2 phones at the same time. I would recommend this charger to anyone that needs a portable charger and great to take on your trips when wall chargers are not easily accessible.

    I’ve owned other portable chargers and this one is definitely the best I’ve had! I only used it for my phone, but it charged it quickly and I was able to charge my phone for about 4 or 5 nights before having to recharge it. Not including the couple of times I’d charge it in the day. It’s a great backup to have when you don’t have access to an outlet!
