Nano Power Bank, Mini Portable Charger with Built-In Foldable USB-C Connector, 5,000mAh Battery Pack 22.5W, For iPhone 16/15, Samsung S23 Series, Note20 Series, Huawei, iPad, AirPods, and More

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.

Great item, really small and ideal for emergencies

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.

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!

Compact, lightweight, and easy to carry your pocket. Charges a phone to full once, which makes it ideal for day trips or short travel where you just need a reliable backup. Not the right pick if you need multiple charges or are away for several days, but for its size and price, it delivers.

Its a nice form factor. I like that I can plug it into my Pixel 10 Pro with the USB C plug, or I can connect it with a cable. It is small, smooth, and feels sturdy. I just took one with me around India and found that it worked perfectly as a topper upper when I was away from a plug socket, so perfect to give my phone a boost when I was on a train, or catching a flight but it definitively has limitations. I would estimate at best it will charge my phone 50%, and it isn't exactly fast doing so either.. So, if you just want to have that reassurance that you've got an ability to boost your phone charge without carrying a heavy brick, then this is a good buy. If you really do want to get a full charge, or maybe more than a full charge, then this is not for you. One neat feature is daisy chain charging, at night plug it into your phone using the fold out USB C plug on it, and then plug it into a wall with a cable. The power then charges the Anker, which in turn charges the phone. You wake up to a fully charged phone and a fully charged power bank. I guess all do this, thinking about it but it worked really well for me, knowing I had a fully charged power bank ready every morning, as well as a fully charged phone. 4 stars because whilst I knew it wouldn't give me full charge, it actually gives me less than I was expecting.

Batería pequeña, puedes llevarla en el bolsillo y para lo que quería que es para un apuro te carga el móvil perfectamente. Además es bastante rápida la carga y no necesitas cable

Very handy for charging on the go. Fast

Ich habe die Anker Nano Powerbank im November 2025 gekauft und schreibe diese Rezension bewusst erst jetzt, nach gut 6 Monaten intensiver Nutzung. Ich bin der Meinung, dass Rezensionen, die direkt nach dem Auspacken verfasst werden, kaum Aussagekraft haben. Erst der Alltagstest zeigt, was ein Akku wirklich taugt. Hier ist mein ehrliches Fazit nach einem halben Jahr: Das hat mich überzeugt: Der faltbare USB-C-Stecker ist top. Man braucht kein extra Kabel und der Klappmechanismus hält auch nach 6 Monaten noch fest und leiert nicht aus. Die Powerbank ist extrem klein und leicht. Sie verschwindet problemlos in der Hosentasche oder Handtasche und fällt kaum ins Gewicht. Ladegeschwindigkeit: Mit den 22.5W lädt sie mein Smartphone (und sogar das iPad) angenehm flott auf. Für den schnellen Energieschub zwischendurch ideal. Das sollte man vor dem Kauf wissen: Die Kapazität (5000mAh): Man muss sich bewusst sein, was 5000mAh bedeuten. Durch den natürlichen Energieverlust beim Laden reicht eine Ladung im Alltag aus, um ein modernes Smartphone 1-mal vollzuladen. Als "Lebensretter" für den Notfall perfekt, aber für ein langes Wochenende ohne Steckdose ist sie zu klein. Passform mit Hülle: Wenn man eine sehr dicke oder extrem robuste Schutzhülle (z. B. Outdoor-Cases) am Handy hat, kann es sein, dass der Stecker nicht tief genug reingeht. Bei normalen, dünneren Hüllen klappt es aber problemlos. Fazit nach 6 Monaten: Die Powerbank hält qualitativ, was Anker verspricht. Die Leistung hat nach dem halben Jahr nicht nachgelassen. Wer eine ultrakompakte Notfall-Powerbank ohne Kabelsalat sucht, macht hier absolut nichts falsch.

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.

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