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.

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.

Light weight and small to attach to phone . Good in colour and looks . This replaces a previous Anker product. Battery indicator tells you how much power on charge. Price is ideal for product

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.

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.

It’s good for an emergency and to give you a little power. Quick charger and small and compact, however it doesn’t provide a lot of battery so if you need a lot of charge then this isn’t the charger for you!

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.

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
