    The best things about are that it's small, light, comes with usb-c flip-up nub, and can fully recharge a phone at least once from zero. What it says on the tin. Gets you about 3 to 4 recharges for a Samsung A25, do your own math for your phone/device (google milliAmpere-hours). Could be better in a few ways, including some degree of waterproofing or the ability to pass-through data. Get it if you want something that works, is unobtrusive, and wouldn't bother you too much to lose.

    This Anker Nano Power Bank is a lifesaver! It’s super compact, charges my phone fast with its built-in USB-C plug, and I love not needing any cables. Great for travel, commuting, or emergency top-ups. The foldable connector is genius, and it fits right in your pocket. A+ from Anker once again!

    I like how portable this charger is. I prefer to use it with a cable but the built in dongle works fine. Great for trips out or an extra boost and extremely light.

    I purchased this Anker portable charger from Best Buy and couldn’t be happier with it. It’s compact, charges my phone super fast, and holds power for multiple charges. Perfect for travel, work, or long days out. Definitely worth the investment—highly recommend!

    Wanted a power bank that I could easily put in a purse or backpack. AND not have to deal with cords to charge up my phone. Tried it out for the first time and quick charge up to 85%. Still has power remaining in the power bank after charging my phone. Will be taking with me both on the road and on vacation. So far so good.

    Honestly I just love how compact and pocketable it is while still offering fast charging to phones that support it. The battery is on the smaller side but for the price I think it's worth it.

    This is just a simple one. It's small so it can fit in a bag. It's 5000mah so can easily fill up any phone at least once with some change. It has a charging port on the side which can also act as and output in case you need to charge something else that can't be maneuvered onto the main charging port. Not the fastest charging but you can just plug this in and set your phone off to the side and you'll be easily topped up. I would even dare to say you could buy multiples of these and use them through the day and charge them back up once you get to back home or work.

    Amazing battery pack. Always charges quickly and efficiently. Can charge phone and use usb type c to charge something else at the same time. I usually hook up a usb c hub and charge multiple items from this

    Been using this for a while now and love it. Good capacity, and very convenient when you are busy with multiple meetings a day and uses your phone for most of your daily activities. This is my second purchase! Also ANKER products are awesome!

    Does it exactly what it says. Great design, compact, not too heavy, but not cheap feeling. Charges fast in both directions, and the type side connection can charge both ways from one port. Would purchase again.

    This is a great item to have while traveling. It is light weight and can fit well in most pockets or cross body bags. I have a Pixel 6 and it was able to charge my phone roughly to half battery when my power was low. Unfortunately it will not charge my phone all the way but did the job when I was out and about all day and not near any plugs. From my experience traveling abroad, my phone was able to be charged and the battery wasn't too clunky. I could definitely use my phone while charging and put it in my pocket.

    Great Charger for Quick and Fast Charging

    Needed a portable charger for times where I would need a quick charge. Does a great job of quickly charging my phone and other devices. I would say the only set back is that it does not hold power very long and I have to make sure to also charge the portable charger at times. Overall great charger, but lacks holding enough power to last long runs of charging.

    This was essential on our trip to Disneyland where we needed to use the app all day. It attaches easily, is lightweight, and lasts a long time.
