    Quick Charge, a little heavy!

    Fast charge! Can be used a couple of times. Just wish it was a little lighter. Really weighs down my purse. Needed to find a cord for charging purposes.

    Great power bank to use, but long charging time.

    Only knock I have on this power bank is the time it takes to charge it fully. From empty to full is nearly 8 hours, so this is one you really need to think about putting it on to charge at bed time. Two USB-A ports and a USB-C port, which is used to charge the bank and also charge other devices with quick charge. The size really isn't much bigger than my 10,000 mAh and you get twice the capacity. Also comes with a nice mesh style carrying case. Anker did a nice job on this one.

    This is a truly SUPERB, fast battery charger. I had many over the years and this one is much lighter and charges the phone much faster. I'm an entertainer and I carry it with me on all my trips. HIGHLY RECOMMENDED!

    I used the Anker portable battery charger pack on a recent trip and I was not disappointed. I used it to charge a Samsung 8" Android tablet from about 20% charge to full charge and still had plenty of juice left to charge an iPhone 12, a pair of Sony bluetooth over the ear noise canceling headphones and a pair of Samsung earbuds and still had half capacity left. The single button lets you check how much capacity you have left. The size is roughly that of a smartphone and weighs about the same as a can of soda. You can easily toss it in auxiliary pouches of a backpack or a purse without it taking up too much space. I like the USB C charging port in addition to the 2 USB A ports. The price point is competitive and with its charging capacity, size and simplicity easily makes this my new go to charging pack. Anker products are solid and always a good value. Well done Anker for hitting another one out of the park. Simple is always better!!!

    Charges fast and works great with my Pixel 6. Also includes a nice little travel pouch. We have several Anker products including cables and such and the quality has always been good.

    I just used it while in New York. I like that it’s not too heavy and feels good in your hand. I could charge my phone while in my handbag. Anker makes great products

    It has a lot of power and charges my iPhone really fast, with lots of charging capacity left over. However, it needs a cable that will plug into an iPhone.
