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 little device - and customer service!
**UPDATE** I'm going to keep my original review here as I think it is absolutely worth knowing that this is the risk. HOWEVER, I've got to say Anker have been the absolute best with the whole issue. To give context: I bought the powerbank December 2024. My first one broke whilst mid travel in Australia, sometime around March 2025. The actual powerbank still charged but the attached lead must've had a dodgy connection and failed. I wasn't able to contact Anker until 30th September 2025 as I was still mid travel, however the moment I did, they understandably sent me troubleshooting steps before asking for order number etc. They immediately applied for a replacement order for me and by the afternoon of 1st October 2025, I had received notification that a replacement was being sent out to me. All whilst I kept the damaged one. Since then, I have used the new battery just as hard, also whilst travelling and not had a single issue. I've still got my old one which can still be used with an external lead - which works perfectly as my partner has a phone still with a lightning port, so he now uses that one. The battery on that one is still running strong and charges his phone 2-3 times which is great, and please bear in mind that they have both recently been in use in -20C skiing in Japan. My inital review was not too impressed with the product as I bought it originally for the built in lead, which I still agree is why I went for it in the first place. But considering I've had no issues with this new one at all, despite arguably more challenging conditions, definitely solidifies that it was just a one off faulty case with the initial one. And I can absolutely not fault Anker in the slightest with their customer support. I use their other products and have never had any issues. If this powerbank suits what you're looking for - I'd say go for it. You genuinely cannot go wrong with Anker and their service. -------------------------------------------------------- Okay when it works... I loved it. Was perfect for what I needed it for, which was to come travelling with me. Not incredible amounts of charge in it but good enough for what it was needed for and it's small so you've got to expect that. However, it's practically useless. I chose this specific one due to the inbuilt lead, but that lasted all of 3 months (not of constant use). Now there's a dodgy connection and that lead does not work. You may get it to start charging but you've only got to look at it and it disconnects. I don't like carrying a seperate lead around with me as I feel they get damaged or lost - but now I have to as the one reason I got this particular model was for the built in lead.

Great USB-C power bank
This is a great power bank that is very reliable. The design is good with the built in C cable as well as other ports. You can charge in and out using the cable built in, while not getting too hot when in use. The power bank is well priced and light to carry around in a pocket. It will charge the phone well twice which is as expected for the battery life.

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! 👏

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.

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 👍

Excellent quality and longevity.
I’ve had this for a couple of years now, it’s been fantastic. The dimensions are approx. 105 x 53 x 25mm. The built-in USB Type-C cable is brilliant, it doubles as a handle and the coating used around it makes it quite durable. The biggest advantage of this is not having to carry an additional cable around (unless you need to charge something that doesn’t use USB type-C) It also has a small built-in screen, which is bright, easy to read and also gives a clear indication of how much charge is remaining. The two built-in ports are 1x USB type-A (for connecting other cables to charge from) 1x USB type-C (this is used to charge the power bank itself as well as connecting other cables) Its size makes it easy to carry around in a bag or the pocket of a jacket but it’s fairly thick so I personally don’t like to carry it in a trouser pocket

Useless Battery Pack! :(
Very disappointed with this battery pack, despite it being an Anker - which is a reliable brand, 99% of the time that I’ve used it (I’ve had it 1+ years) instead of charging my phone …..it’s used my phone, to charge itself!! I’d look over at my phone to check how much battery it has gained, and find it’s dead but the battery pack is now 100%! (E.g. the battery pack would start as 80% and my phone on 20%…. After 20 mins the battery pack is 100% and my phone is 0%!) (& yes, I am using the right output and inputs on the side, it doesn’t seem to matter which cord I use, even the one that’s attached to it! #cry) The shape, weight and size is so practical for a handbag, it’s just completely useless as it makes your phone die. Ironic! Maybe I got a lemon 🍋:(

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.

Batterie puissante, maline et stylée
Gros coup de cœur pour cette nouvelle batterie Anker Nano. Les batteries, j’en ai déjà un certain nombre, mais j’avoue avoir craqué pour son look, son écran dissimulé et invisible lorsque la batterie est éteinte, et cette lanière/fil de chargement intégré. C’est ultra pratique et plus besoin de chercher un câble supplémentaire. Ce câble intégré permet la charge de son téléphone ou de son iPad, mais il sert aussi à recharger la batterie lorsqu’on le branche à un chargeur. Vitesse de chargement : batterie dernière génération et ça se sent : c’est du rapide! à la fois pour recharger la batterie en tant que tel, mais surtout pour charger mon iPhone 15 à une vitesse éclair. Elle est très efficace aussi pour mon iPad air. Look : c’est une des raisons pour laquelle je l’ai achetée : super sobre et classe, avec un effet métallisé de toute beauté. Elle respire la qualité et la solidité. Poids : pour une batterie de 10000mAh, il existe plus fin et plus léger, mais ça sera beaucoup moins puissant et rapide à la recharge. Finalement mon seul regret est qu’elle n’est pas assez puissante pour recharger mon PC portable Dell, qui aurait été mon graal (a priori, ça fonctionnerait sur un MacBook). C’est en tout cas une batterie que je recommande chaudement et qui est positionnée à un rapport qualité/prix de tout premier ordre.

Compact and modern battery bank | Many pros, one con
My old and trusty Anker 15,000mAh power bank served me exceptionally well over the last 4 years. However, it’s getting to the point where it could use an additional reliable companion for those longer trips or power-hungry days. I decided to search for a new battery bank that could keep up with the performance of my trusty old one. This 10,000mAh battery bank looked interesting and it arrived within 2 days. It looked like a well-designed compact device, packed with a display and an integrated cable. Here are my impressions after using it for 7 days. Design and Portability: The bank is one of the smallest and compact 10,000 mAh battery out there. The secure loop cable is surprisingly hanging from your fingers. It can be used to charge your devices and charge the bank itself when connected to a source. 3 Ports and Power Delivery: With two bi-directional USB-C ports, and one USB-A port, it supports charging multiple devices at once and delivers up to 30W. You can charge upto 3 devices at once, but 30W will be shared between them, i.e., 10W each. Not bad given just few years ago phones used to charge at 5W speeds. Performance and Charging Experience: Even when nearly full, it continues to charge fast, accepting charge up to 20W even at 99%. Time Display and Accuracy: The digital display shows battery percentage and charging time. This is extremely convenient compared to 4 blinking LEDs. The display can also tell you how long before your phone/device charges to full which was quite accurate in my testing. CON: The only con of the power bank is the lack of pass-through charging, meaning you can't charge devices while the power bank itself is charging. Additional testing: I also compared this bank against one that comes without integrated cable. They are both identical in performance and I didn't notice any difference in initial short testing.
