Good power bank, excellent customer service when it went wrong
This is an really good power bank. When fully charged it easily charges my old Pixel phone twice. The display is useful, its a reasonable size/weight and I like the built-in cable - you can use it as a carrying handle and it has stood up to it so far with no sign of damage! Unfortunately, after 6 months there was a slight problem. After having charged my phone, I laid the battery bank down with nothing connected to it. On returning to it a few hours later, it was extremely hot around the top, and the display had stopped working. Its quite disturbing when something is getting hot and there's nothing you can do to control it. So I took it out to my cold garage, where it fully discharged itself. I didn't take the risk of trying to use it again. I was outside of the Amazon return window, so I phoned the Anker UK support number. A recorded voice said they would call me back, which they did within a few minutes. A real person took all the details, they then emailed me asking for my shipping details. A week later I had a replacement! I did not have to return the old one, they suggested I recycle it. Five stars for excellent customer service, wouldn't it would be great if all companies could be so helpful. The replacement unit works fine. But what happened with my old one along with news media coverage of Li-ion battery fires/explosions over the last year or so has reminded me to use these things with a little more caution now. So, assuming the new one doesn't develop the same problem, it's five stars from me 👍

Perfct little power bank
Perfect little power bank! Very portable size and weight, so extremely easy to transport in a bag/pocket if necessary - obviously depending on what you're wearing. Screen shows remaining charge very clearly - thats all it does, but you don't really need anything else in all honesty. The attached cable is a brilliant quality-of-life feature (one less thing to carry/forget to bring). Can also accommodate a second cable if you think you might need to charge 2 devices at once, though realistically it can top up our mobiles by 50-60% in 30 mins, so if 2 people need it you could just take it in turns very easily. Enough capacity for two full charge cycles near enough, so perfect for a long day or even weekend out and about, but you might want to consider a larger capacity if you're going on a longer trip. No heat issues detected, charging works flawlessly, powerbank charges up itself quickly so is always ready to go - literally perfect for what my son wanted, and I'm about to order another for my own work travels. Great value for money for this quality - Anker has been one of go-to brands for many years now, is known for exceptional customer service and and quite literally never let us down.

Absolute workhorse, but it does not have pass-through charging (newer models do)
This battery basically keeps my family's devices - phones, iPads and laptops - charged (one or two at a time, obviously). With 30w output, it will charge a MacBook (though not a full charge, obviously), and juices up phones and other devices super quickly. it's also a very small unit, which makes it great for travelling, or just lugging around when your device is otherwise out of power. I wasn't sure about the built-in cable at first, but it's survived some pretty significant abuse over the last 6 months, and with a USB-C and USB-A port on there too, even if it did break it would still be a usable unit. The display shows percentage left, which is handy. Unlike newer / larger Anker models, this one doesn't show individual port wattages, but it will give you an estimated time left (be it discharge, or charge) so still very handy. It also seems to be fairly consistently on sale, so at the price I got it at - £26 - it's an absolute steal. the only thing to consider is that the newer version, which comes with an on-board Apple Watch charger too, whilst bulkier, does also come with pass-through charging (where you charge the battery from the wall and devices from the battery at the same time), which you don't realise you need in your life until you're travelling and no one but you in the entire family brings so much as a charging cable. It (the newer version) also has port reporting on watts being consumed which is handy to know, but not really essential. All in all, I can't recommend this battery enough. Anker is a brand I trust, and this battery pack has put the work in already in our house and on our travels, with plenty of life left in it yet.

Great power bank
One of the best power banks on the market. The built-in USBC cable is absolutely amazing. You can hold the power bank via the cable while using it to charge your phone so it comes in very handy. The capacity of the power bank is great for a day trip. There is a very good weight of the product so it doesn’t feel flimsy. Even after numerous drops and quite extensive usage daily for nearly a year it still works perfectly fine. It comes in a range of colours that all look very smart. The best thing about this is also potentially the worst. As the USBC cable is hardwired into the power bank if it breaks, you’re not able to replace it. Considering the price though it is very cheap to replace if this does happen.

Ultra-Compact Powerhouse: Anker's Game-Changer for On-the-Go Charging!
Review for Anker Nano Power Bank, 10,000mAh Portable Charger ⭐️⭐️⭐️⭐️⭐️ I've recently had the pleasure of using the Anker Nano Power Bank, and I must say I'm thoroughly impressed. Right out of the box, its small and compact design appealed to me – perfect for on-the-go individuals who don't want the burden of carrying a hefty charger. The silver color gives it a sleek look, though I'm curious to see how the black version compares. The built-in USB-C cable is a fantastic addition, greatly reducing the need to carry around an extra cable. This feature alone adds a lot of convenience to my daily life. While I appreciate the additional two ports for their versatility, I would love to see Anker incorporate two USB-C ports and perhaps do away with the USB-A. It's a small personal preference as I see the world moving more towards USB-C compatibility. Performance-wise, this power bank doesn't disappoint. It charges rapidly at 30W, and I was pleasantly surprised to find that it also outputs at 30W. This means I can achieve maximum charge speed on my devices, including my iPad Pro and iPhone 15 Pro/15 Pro Max. One minor gripe I have is the paint finish. It seems to be a bit of a fingerprint magnet, which means I find myself wiping it down more often than I'd like. However, this is a small issue compared to the overall functionality and design of the product. In conclusion, Anker has once again proven why they're a leader in the portable charging industry. This power bank is a fantastic product, and I wholeheartedly recommend it to anyone in the market for a reliable and efficient power solution. Well done, Anker! 👏

Great product
Excellent purchase. Practically.. gives a full charge to my iPhone, so great to have at hand as a back up. Stylish design too. Personally, although there’s charge points everywhere these days, I can’t abide carrying charging cables, so this works for me.

Amazing
This charges my phone 3 times on one charge and has lasted me more than a year. The power it holds and the charge speed has not decreased, this also has endured a few drops and continues to work flawlessly. It is small enough to have in a pocket and doesn't take any space as it is compact and light. The automatically attached wire for charging makes it complete and easy to use.

Failed after 25 months; buy something else.
Great while it lasted - which wasn't very long. Very light use, with only a few cycles, and it's dead. Charged it one evening, unplugging it around 95%, and it turned off and remained off. None of the reset instructions had any effect. Clearly it's the circuitry that's failed and not the battery. Anker's AI customer service is not interested in doing anything useful. Lasted a total of 25 months (a month out of warranty) - Anker is meant to be better than the cheap unreliable rubbish that's widely available; very disappointed indeed.

10.000 mAh PowerBank
Ich war auf der Suche nach einer Powerbank, die nicht nur stark genug für mein iPhone 16 Pro Max ist, sondern auch kompakt und unkompliziert in der Handhabung – genau das erfüllt die Anker Nano Powerbank mit Bravour. Das absolute Highlight für mich ist das integrierte USB-C-Kabel: Kein zusätzliches Kabel nötig, kein Suchen in der Tasche – einfach anschließen und laden. Das spart Zeit und macht die Powerbank zum idealen Begleiter für unterwegs, besonders wenn man iPhone und iPad mit USB-C nutzt. Die Ladeleistung ist beeindruckend, ich konnte mein iPhone 17 Pro schnell und mehrfach nachladen. Auch das parallele Laden über USB-A (z. B. für Kopfhörer) funktioniert problemlos. Die Powerbank ist wertig verarbeitet, extrem handlich und passt locker in jede Jackentasche. Das matte Finish sorgt für guten Grip und wirkt gleichzeitig elegant. Weitere Pluspunkte: • LED-Anzeige mit klarer Restladestandsanzeige • 10.000 mAh Kapazität reichen locker für 2–3 volle Smartphone-Ladungen • Schnellladefunktion funktioniert auch am iPad zuverlässig • Ideal für Reisen, Uni oder den Alltag Fazit: Eine der durchdachtesten Powerbanks, die ich bisher genutzt habe. Besonders für alle, die Geräte mit USB-C nutzen, ist sie eine echte Empfehlung. 5 Sterne – klare Kaufempfehlung, insbesondere für iPhone 17Pro Besitzer.
