    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.

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 was looking for a good portable charger to use while I’m at work. Since I prefer to have my phone by me at all times instead of leaving it somewhere by an outlet. It takes a bit to fully charge since I’m using the Apple block. But it lasts a long time it’s been 5 days since last full charge and it’s still going strong. It doesn’t come with it’s own charging block. The cable is included.

    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!

    I bought this item due to the brand Anker. I read the reviews online from customers who have purchased items from Anker and they were very satisfied with their products. My relative has a smaller portable charger and she is very pleased with it. I also like the idea of the nylon carry bag that allows me to place the charger and cord inside the bag so it will not be damaged.

    I bought this on the recommendation of a BB sales associate and couldn't be happier. I needed to replace a 30k battery pack I've had for years as the ports had finally worn out. Dual USB ports, 1 standard and 1 quick charge. Solid, well made and doesn't take forever to fully charge. It's not small in size but considering its capacity it's not overly large either. Great price as well.
