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.

The Anker Nano Power Bank is a compact and reliable charging solution for on-the-go use. Despite its small size, it delivers fast and efficient charging, thanks to Anker’s PowerIQ technology. Its lightweight design makes it easy to slip into a pocket or bag, perfect for travel or daily carry. While it may not have the highest capacity for multiple full-device charges, it excels as a quick top-up solution for smartphones and small devices. Overall, it’s a sleek, dependable power bank that balances portability and performance.

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.

A pocket‑sized, 100 g power bank with a foldable USB‑C that doubles as a direct Pocket 3 power source and a fast charger for any USB‑C device - ideal for travel. Pros: - Built‑in USB‑C docks straight into Pocket 3 and most phones with slim cases - Up to 22.5 W fast output; dual USB‑C for charging a second device or recharging the bank - ActiveShield 2.0 safety with temperature monitoring - 73% PCR outer shell; compact and light for everyday carry - Truly versatile—better value than a single‑purpose Pocket 3 battery Cons: - Real‑world usable capacity ~2,600 mAh at 5 V from the 5,000 mAh cell - Must hold phone and bank when connected to protect the foldable plug - Not compatible with very thick cases (over 4.9 mm) Verdict: A travel favourite and an easy upgrade over a dedicated Pocket 3 battery. Buy one—or two—for reliable top‑ups to your Pocket 3, phone, and other USB‑C gear without adding bulk.

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.

I have purchased two of these. While they only get occasional use there has not been any noticeable drop in charge held. They charge quickly, hold a reasonable amount of power for their small size. Perfect for carrying in a pocket. They are built well, the folding USB C connector holds in position firmly with no wobble. The C connecter is long so things like phone cases or deeper sockets in devices are no problem. Power level display is simple but works great. For a quick, portable charge that does not require cables these things are great.

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.

I bought this at the same time as a similar non big brand charger that was advertised at 7000 capacity (The anker is 5000. ) However this Anker charger charges my iPhone fully more quickly and doesn’t get hot also it is smaller and lighter
