Anker Nano Power Bank,5,000mAh Portable Charger, Built-In USB-C Connector

Excellent product. It is so small and easy to carry that I actually keep it plugged into my phone while using it on power-saving mode, running off the power bank instead of my internal battery. It works brilliantly, delivers a reliable charge, and has become an essential part of my daily routine.

I was looking for a small lightweight power bank and I was so pleased when I found this. I love the fact it's cable-free and so easy to use. Whenever I'm travelling, I can top-up my phone whilst still using my phone as it's so compact and lightweight. I love the fact that no cable is required. It has excellent battery life and has light-up dots to indicate how much battery life is remaining. I have never run out of charge when travelling.

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.

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!

This is an neat and well-designed bit of kit. It is lighweight, compact and needs no cables as it plugs direct to your phone with a built-in fold-away USB-C connector. It gave my Samsung S22 a full charge from 0 to 100% in under an hour and still had some power left over. It is much smaller and lighter than my previous power bank and does everything I need it to do.

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.

Pros It's small and easy to carry around in a pocket. It charges up quite quickly. You can fold the USB-C away so it doesn't get damaged while in your pocket or bag. Nice colour. Cons Probably does not hold enough power to charge a phone to 100% The charger does not fit tightly to the bottom of your phone, it leaves a gap. While not the worst thing, it just means you need to extend your hand lower to hold the charger, unless you want to trust the USB to hold it. Conclusion For what I paid this is not a bad product. I am not unhappy and I would probably give 3.5 stars if I could. It's best quality is that it is light and small. However, the low capacity means you need to charge it every time you use it. For most cases I would probably just recommend a full size power bank. It has uses, they are just quite niche.

Don't expect miracles. This will charge your phone once, maybe a little more. And that's why it doesn't get five stars. I wish it did more or lasted longer. But on the plus side it is so easy to add to your phone and even stick in your back pocket. I have it in the care just in case. Get one.

Very handy for charging on the go. Fast

Tenho um Poco X7 Pro, essa bateria carregou de 0% → 60% em situação ideal, sem mexer no celular... Usando ele como é pensado pra ser usado, deve carregar perto de 50%, o carregamento que ele proporciona é rápido, mesmo com você mexendo da pra ver que a bateria sobe, não fica estacionada como outras baterias de carregamento mega lento... A fixação é boa, usando normalmente não deve cair nunca, mas como uso o celular no suporte na moto, precisei fazer uma gambiarra na capinha do celular como uma espécie de "cinto de segurança" pra poder usar ela mesmo andando de moto... Eu uso o celular literalmente o tempo todo, trabalho usando o celular e preciso sempre de estar com o brilho no maximo pois uso o celular no sol da manhã entre 8h e 15h na moto, e com bluetooth e 5g sempre ligados... E com essa bateria consigo usar o celular mais de 12 horas, mesmo depois de chegar em casa ainda consigo usar o celular de maneira mais leve até a hora de dormir, quando ponho tudo pra carregar... Sinceramente, me atende muito bem, pra mim serviu perfeitamente pro que eu precisava, fazer a bateria do celular durar o dia todo rodando fazendo entregas, é extremamente compacto relativamente leve, levo no meu bolso quando não estou usando e não me incomoda nenhum pouco, nota 10/10, não tenho pontos a reclamar, valeu cada centavo.

Działa świetnie, jest bardzo lekki i mały jak na powerbank. Szybko ładuje i bez problemu można korzystać z telefonu, gdy jest podłączony. Polecam!"

Very happy with my Nano power bank, it’s small and you can take it every where with you

Excellent powerbank very compact and light weight enough juice for day to day life
