    Bought this just to use occasionally on a cross country road trip and back. It worked great for my iPhone 16 Pro. Was able to get about 2 full charges out of it before it needed charged again itself. Its super light weight and compact. Super easy to slip in a pocket, fanny pack, purse, etc etc. Probably one of the best in this size category for portable chargers. Would definitely recommend.

    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.

    Anker makes great products and this follows that statement. Well made and designed. Fits my pixel fold like it was part of the phone and charges it completely. No screens or crazy thrills but does what it needs to and does it well. Checked and my battery reader states it has 5120mah so your getting more than expected unlike many portable batteries. I would buy it again without hesitation!

    Works as advertised. Will charge quickly. Only flaw is that it’s pretty delicate, so you don’t wanna lift and use your phone while it’s charging or it could disconnect and fall to the floor

    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 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!

    Brought it to recharge my phone on long hikes. Worked great gave me the ability to take pictures on a 12 hour hike. I was also able to keep my garmin bike computer charged on a 160 mile ride. Fit in my bike jersey and hiking pants pocket.

    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.

    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.

    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.
