    This little power bank is super convenient! The foldable USB-C plug means I don’t have to carry a cable, and it charges my phone fast for its size. Perfect for travel or daily carry when I just need a quick boost. Not meant for multiple full charges, but exactly what I wanted for a compact backup.”

    A little inconvenient for my iPhone, but it works with an additional cord. Good to have in a pinch, but not a ton of charge on it, but enough.

    I love this portable charger, first bought it during a power outage - it now lives in my purse. It's compact, fast charging no more panic that my phone is dead - and have no charging cable, etc. Excellent for train/subway travel charging, et.

    This little thing is so portable and handy. It definitely could carry more of a charge but for the price and size, it does a great job. I would recommend for a small, convenient choice of portable batteries.

    This little guy is pretty alright. Even though it is a 5,000 mah battery it will really only charge about 50-70%, but that’s sort of expected. It’s real purpose is to give juice to your phone in cases where a better power bank would be inconvenient to carry. That’s because it’s pretty tiny, being easily pocketable. If your looking to charge your phone at least a couple of times. Any 20,000 mah power bank should do the trick.

    Pretty good job charging overall. Can get a fully charged battery on iphone 15 pro max but it will drain most of the battery rendering the device useless after about an hour of use. Just remember to charge it after hsing it and its fine. Good for the price too!

    This battery backup is exactly what I wanted. It’s small so it doesn’t take up much space and it’s not heavy. It gives me the security I was looking for should my phone be low on charge while traveling. It only charges to 70%, but that’s really all I need as backup.

    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.

    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 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.

    I purchased this for an upcoming trip mainly because it connects directly to my phone. The charge was quick but my phone and unit did get warm during charging. It comes with a USB type A to C cable--I suggest buying a C-to-C cable for a faster recharge of the unit.

    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.

    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
