    Great little portable charger. Small and charges fast! This will only charge your phone once so if you’re expecting multiple charges you will need to upgrade to something bigger. This is good for something in a pinch.

    Best charger hands down!!! Love this little guy, so small but powerful. Nice that the phone can just sit on top of the charger. I lost the first one I bought and missed it so much I went and bought another.

    This is the second Anker - Nao Power Bank that we have ordered for our teen daughter. She used the first one on a few different trips and it worked great. She lost the first one on the last school trip that she took. She said that the power bank worked great and is easy to carry around.

    What I like about this charger is that it’s small so it fits anywhere and lightweight. Forget about all those cables or bulky portable chargers! The charging port flips up when you’re using then you flip it down when you don’t need it which is awesome imo. I gave 4/5 stars only because it didn’t get my phone to a full charge. So I would use this most of a boost but I wouldn’t expect it to charge it fully. I would still very much recommend because the pros outweigh my only con.

    This Power Bank is a great solution for those who need a quick power boost while out and about. Its 5000mAh capacity may only provide one full charge for most smartphones, but its incredibly small and portable size makes it super convenient. The foldable USB-C connector means you don't have to worry about carrying extra cables. If you're looking for a compact charger for occasional emergencies, the Anker Nano Power Bank is a great option. Its pocket-sized design and built-in connector make it perfect for staying powered on the go.

    Its exactly what it looks like. I got it because i wanted a nifty little power bank that has no wires and this delivers on that. It charges my Samsung S22 (base version) from 0% - 85% so its good. Hopefully anker improves on this in the future with bigger and better capacity while keeping it small. If you need a full charge or few charges, this definitely is not for that. I need it while im out and about on a trip to the city and just need my phone to not die. I also just didnt want the hassle of remembering wires. Neat thing about this is that you can charge other USB C things like ps5 controllers and headphones. Makes it versatile. The hinge feels firm but a little flimsy so good build quality but nothing amazing.

    This is a handy charger. We love that there is no cord that tethers your phone. It just plugs into the bottom of the phone to charge. Charging well so far.

    Great for carry when outside and you only need recharge once to "make it" to home. Its small enough to carry on the pocket along keys, without needing extra cables. The USB-C tip is a "weak point" for durability but I've no problem with it so far, and also having the option to use cable tells that it was well thought designed.

    I usually charge my Pixel 7 whenever it reaches 20% battery and this bank easily fully charges my phone to 100% and by then I have to charge the bank again. Im okay with that and that's exactly what I need it for. I leave the bank plugged in my phone while its in my pocket and have no trouble pulling it out if I need to. It's Super convenient and compact. It offers 22.5w charging, not the fastest but fast enough in my opinion. It was also an open box item so I saved a few dabloons there.

    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 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.

    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.

    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.”
