    Anker powercore 20000 comes with both quick charge and power iq so you can charge both android and iOS devices faster. 20000 mah in this price is amazing.

    I charge that battery once or twice a week and it has a green port for fast charging and a slow one. It"s not too wide perfect for traveling.

    I own several Anker products and they never disappoint. A lot of power for the size. Took this on a fishing trip for a couple days and had plenty of power.

    Works great so far no problems. I do wish it were flatter and wider to fit in my pocket a little better. For the price point and amount of power it has hard to beat!

    Bought this charger for airport to airport trips. Great for use when there are no chargers in the terminal and fits easily in bags and pockets for use in the plane.

    I have an older Samsung phone and the battery just doesn't hold it's charge as long as it used to. This charger works great to eliminate that problem.

    It took a while to charge fully on the first charge. I bought it for a cruise and we all used it for our phones while we were off the boat. Love it!

    I bought this for my SIL as she isn't able to use her car outlets. I wanted to get her something that would last and went to my local store and one of the Sales folks there told me for the money it's the best one. Seemed to be very solid and my SIL has used it a couple of times without issues.

    My son really wanted this charger. He kept reminding me to buy it for him for Christmas. He has no complaint about it so he must be very happy with it.

    The first battery (this model) I got was faulty - the third LED did not light up. So I replaced it with another one, and that one is working well.
