I bought the Anker Power Bank in November, and it’s quickly become something I carry with me every day. The size is one of the best features it’s small, lightweight, and fits easily in a pocket or small bag without adding bulk. Despite the compact design, it gives my phone a solid boost when I’m out and about and running low on battery. The build quality feels sturdy and well-made, which is what I’ve come to expect from Anker products. The connection is secure, and it starts charging immediately without any fuss. It’s especially useful for travel, busy days out, or times when I know I won’t have access to a plug.

Having already owned several power banks I really did not need more. However, I recently had little choice but to purchase more power banks due to recent changes in certain regulations for travelling through certain destinations due to incidents involving power banks inflight. To meet the criteria of several airlines/regions/countries, this power bank isn’t high capacity but holds enough juice for topping up my phone with its inbuilt usb c connection. It is quick to charge up (2hrs) and has the following countries’ certifications marked on its casing (CCC, CE, KC, BIS,NOM, PSE) as of March 2026. It was surprising how my other anker power banks lacked most of these certifications and also how hard it was to confirm these details online when purchasing power banks. In fact, these information wasn’t even available on the packaging and was only found after unsealing the box. This power bank is very compact and portable, making it a great companion for travel. It does emphasise that the phone case shouldn’t be too thick to prevent connection issues with the phone. It also has the option of connecting a separate usb c to it if the inbuilt usb c connection cable does not work with the case. It charges my phone well, and does not seem to overheat for me. I have bought 2 (apple green and blush pink) as there will not be enough juice in 1 for 2 phones while out and about for the day. Of note, a restriction on the number of power banks one can travel with are being enforced in some countries (2 per pax is seemingly the new norm for some countries). Both are well constructed. There is no strap anchor for attaching any wristlets. I have not had it for long to be able to judge it’s durability, but all my previous anker power banks are still doing their jobs well.

I like that it's small, good quality, and charges fast. But it will charge my Pixel 8 phone to only 75% max., stopping many times in between. (I think the stopping is an issue with the phone, not the power bank.) So read carefully the small print before buying: "Note: 5,000mAh is the battery capacity calculated based on a 3.6V cell element. When powering your devices, the expected capacity is 2,600mAh (5V/2.4A) due to legitimate energy loss during the charging process." I didn't read that and though it's 5,000mAh and would charge my Pixel to full, which it won't. Disappointing. Still, I decided to keep it as it'll be useful for travel. As always - excellent customer service from Anker.

Anker Nano Power Bank. Pink Not Purple., You Will Be Pleased To Learn That. I Have Raised This With Both Anker/ Amazon. Yet Still It Reads Purple. It’s Portable, Compact, Cute, Functional, Lightweight, Suitable For Arthritic Hands. I Found It, Absolutely Vital , In My Recent Stay In Hospital. The Price Is Cheap. So I Wasn’t Expecting Much. I Was Actually Amazed By It . I’m Going To Order More, For My Family. I Personally Would Say Anker, Who Are Also Known As Soundcore Are No1 In Their Products. I’ve Only Had One Rouge Item. Even Then, Their Customer Service Was Outstanding.

This is a lovely very useful power bank, I wanted a pocket sized power bank for my son to easily take in his pocket on a night out. After ordering several other makes and styles which were all were either too big or too heavy, this one was exactly what I wanted. Especially as there is no additional cable needed as it connects directly to the phone when needed and the port folds away neatly when not required. He finds it the perfect size to carry discreetly in his pocket when out and it is a robust durable design with a long battery life. It is great value for money and has given his phone a valuable battery boost on many occasions now. I highly recommend it for peace of mind!

A natty little charger. Very handy to slip into your pocket and give your phone a midday boost. It won't repair a larger power bank but handy when you're a bit low and going out. Bought for skiing where the cold eats battery life quickly. All the lads were boring it to get them up to 20% etc. Can't fault it.

Does exactly what is says, is small, easy to travel with and charged my appliances.

Very nifty; stays attached unaided; is perfectly sized; recessed plug great - an ideal gift otherwise a very essential item. It does get warm - but don’t be put off.

Very handy for charging on the go. Fast

I got both the white and black versions—definitely recommend the black because the white gets dirty really fast. The power bank itself is great: small, charges my iPhone quickly up to 90% or more, and easy to carry in a pocket or bag. Good quality.

batterie de petit format, tres pratique et utile pour dépannage quand la batterie du téléphone et presque vide, permet de récupérer pas mal de charge et de tenir plus longtemps.

Charges great, but after 2months the pack is starting g to come apart. Not sure if it's cells expanding or bad casing. Either way it has to be thrown out for safety.

Es de carga rápida y muy práctica
