Customer Ratings & Reviews

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!

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 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.

Very useful the size is perfect, you can take it everywhere.

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!

Smallit fits a supcase on a flip 6 just wished had more charge

This is perfect. Small, easy to carry. Powers phone quickly.

Very good portable battery small and good efficient charger always Anker.

Very nice product. Nice design. Handy to have and easy to use. Better than having to use another cable

I love Anker charging products. The Nano is perfect size, not super fast but charges fairly fast. I purchased it in Dec 2025 and for reasons I dont remember purchased the BB warranty. Early May 2026 the Nano stopped taking a charge and can only attribute it to the economy charger plug that I was using to recharge the Nano. BB exchanged the Nano, no problem. Now I only recharge it with a premium charger plug. Let's see what happens in 6 months

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.

Powers up my Samsung 25 quickly. Works so well I bought my wife one too

I was honestly impressed. It's only good for one charge, but it does it quick and it's so much easier to carry

this power bank is compact and attaches nicely a the bottom of your phone. Nothing extra to hold onto.

This was super easy to use and fit great in my backpack! I brought it with to use at Disney World to keep my Samsung Galaxy S23 Ultra charged up during the day since cellular data signal is weak there and the phone spends a lot of time trying to reconnect. The only reason I did not give it five stars is because I had it fully charged and my phone was down to about 15% and it could not charge my phone up to 100% before running out of juice. It was great in a bind though to recharge up to about 85%! Overall I would definitely recommend!

The product itself will get 5 stars. It worked well and did the job. The task of trying to register the product gets zero. The company makes it far to difficult to register as if they do not want you to do it. Finally got it completed after contacting customer service twice. They also wrote to me and said you cannot register it if it was bought as best buy and to sent them a receipt.

Great little power bank that fits in my pocket when my phone ran out of batteries. Came precharged. Super handy..and lightweight.

Great mini power bank to give you that extra boost. It's not intended for multiple recharges. For that you would need to move up to a bigger power bank. I used it at Disney when my Google Pixel 7 Pro was at 15% and got it back to 90% in about 1 hour. Its small so you can keep it in your pocket while charging or use the phone as well. When not in use you could still keep it in your pocket or if in a bag it takes up minimal space with no cord to worry about. At the price point and what my intended use was, its been a great buy so far.

I like it. It is plenty to keep a phone charged up for the day. I got it because I thought it would be great to connect directly to the phone while in its holster. Actually, that is not recommended, and it's likely to put too much stress on the phone's USB-C port. I can directly connect while holding in my hand. But it can also be connected via its other port and a USB-C cable. It's small (pocketable) and lightweight.

Everything works great & awesome. It’s kinda fast. BUT I have to take off my phone case. That’s the only con . Other than that super solid device
