Nano Power Bank,5,000mAh Portable Charger, Built-in USB-C Connector

extremely good and convenient portable charger that works well to charge your phone. It hooks to your phone erganomically allowing you to use your phone easily while charging it. It's small and compact allowing it fit in small pockets in your shorts, jeans, and shirts without much weigh down. Only minor drawback is it only has 5000mah meaning it might charge your phone maybe 1.5 times before it's out of juice but for a quick charge on the go, you can't go wrong. If Anker ever releases a 10,000mAh version of this, it will absolutely be worth it to get it if 5000 isn't enough.

I see a bunch of one-star reviews, mostly from people who seem confused about battery capacity, energy, power, voltage, current, etc. People complain that this little pocket-size battery won’t fully charge their iPad. That’s like buying a little one-gallon gasoline can for emergencies, and then complaining that it when you poured it into your truck’s empty gasoline tank it didn’t fill the tank all the way to the top. The cell inside the Anker Nano Power Bank is advertised as having a capacity of 5000 mAh. That means the cell can (for example) supply 5 A for one hour, or 2.5 A for two hours, or 1 A for five hours. Battery engineers like talking about mAh because it is useful for their circuit designs, but for the rest of us it’s not very useful, because knowing the energy in 5000 mAh depends on knowing what voltage we are talking about. For end users, it is more useful to compare batteries based on the energy they store rather than the amount of current they use to deliver that energy. So that means talking about watt-hours (Wh) instead of mAh. For this battery the cell voltage is about 3.6 V, so 5000 mAh gives you 18 Wh. But phones aren’t designed to take power at 3.6 V. Phones require 5 V (or higher). Voltage conversion circuitry is not perfectly efficient. The text on the battery itself claims, “2600 mAh @ 5V x 2.4 A,” which means it can deliver 2.6 x 5 = 13 Wh of energy. This means that the voltage conversion circuitry inside the Anker Nano is about 72% efficient, so the 18 Wh at 3.6 V becomes 13 Wh at 5V (28% of the energy is wasted as heat). In practice, measuring a couple of Anker Nano Power Banks using a USB energy meter, I found they actually deliver 12 Wh (2.4 A @ 5V for one hour). 12 Wh is close to the 13 Wh that Anker claims, but not quite. My iPhone 15 Pro Max has a battery capacity of 17.32 Wh. Charging a battery is also not perfectly efficient — charging makes your phone get warm, and that heat is more wasted energy. If we assume that battery charging is also 72% efficient, then the 12 Wh from the Anker Nano becomes 8.64 Wh in the phone battery, or about half of the my iPhone 15 Pro Max battery capacity. In my experience the Anker Nano does indeed charge my phone from empty to around 50%. Because the Anker Nano supports USB C voltage negotiation, phones that support higher voltages can request up to 10V, allowing the Anker Nano supply up to 22 W for faster charging than a normal USB 5 V supply. The Anker Nano Power Bank is great for unplanned situations where you unexpectedly find your phone battery is drained. The Anker Nano is a small battery that easily fits in a pocket or a bag, and you don’t need to remember to carry a cable with it, because the built-in USB C plug connects directly to the device being charged. If you prefer to use a cable, it also has a USB C socket for that. Last year at the end of a day of skiing I found myself trapped for two hours in a broken-down gondola with four other people. All of their phone batteries were drained, and they were concerned about how they could tell their friends where they were. I pulled the little Anker Nano out of my pocket and passed it around. Within a few minutes everyone had charged their phone 10-15%, enough to call their friends and let them know what was happening.

I’ve got larger power banks (in all senses of the word), but this is the one I reach for when I’m going to be out for a long day using my phone intensively, and I want to make sure my battery doesn’t get too low. It’s small and lightweight, and it’s easy to hold when I’m holding my phone. I get a little less than a full charge from it, but that’s plenty to keep me in the safe zone. It also provides a surprisingly fast charge, so it’s easy to top off my phone quickly. I tried a MagSafe charger from another brand, but it was bulkier, slower, heavier, and more awkward to hold even though it clung to the back of my phone. I choose this one every time.

UPDATE: I've changed my review from 2 stars to 4 stars. Anker seems to be a legitimate honest copy -- they contacted me shortly after my review and offered to refund my money back. They seem to care about their customers, which is a rare thing nowadays with most other companies. So A+ on the customer service! It appears the item I received had a faulty battery. Since Anker stands by their product, and communicates back with the buyer and is honest, I wouldn't hesitate to try buying from this company again. It seems I was one of the rare 3 or 4 people out of a thousand to get a faulty battery. I guess it wasn't my day. OLD: I tested the “Anker Nano Power Bank with built in USB-C connector” and the results were not impressive at all. However, it's possible this maybe because I got a bad charger. Here's what my test showed: Using the power bank charged fully to 100%, I plugged the Anker power bank into my phone. My phone has a 5000mah capacity battery – the same amount of power that Anker claims the Nano can provide. The power bank charged exactly 1 hour and 8 minutes before it died at 0%. My phone was at 27% battery life before charging. After charging my phone with the Anker Nano, it was only able to get my phones battery up to 91% from 27%. So, that’s 27% to 91%. That means this Anker Nano power bank only provided 64% of charge... Doing the math, that means that this is either a bad product; there’s been some false claims, or I received a half functioning dud with a bad battery If the Anker Nano I received isn’t a dud, then that means this power bank is only capable of 3200mah and not the 5000mah power Anker claims or advertises. However, I understand most power banks will be about 10 to 15% off from the mah power that manufactures claim. But since the Anker Nano could only provide my 5000mah phone with 64% juice, that equals out to 36% deficiency in it’s mah power claims. That’s pretty high seeming this is suppose to be a well known and trusted top company. So overall, I’m not impressed at all and feel a little cheated after testing it out. There are several other brand options I could've choose from in around the same price range, so I’m not feeling certain I made the right choice and feel pretty dissapointed. PROS: -It’s compact. It looks nice. CONS: -1 hour and 8 minutes charge time before power bank dies. -Provides only 64% juice to a 5000mah phone battery before it dies. -Doing the math, 64% = 3200mah of power, not 5000mah of power as described by Anker’s description. (...however, it is possible mine may be a dud??) Conclusion: I plan to test some more Anker and other branded products in the future, and I will update once my comparison is complete. I am still searching for a lightweight charging option that works with at least 80% efficiency, as most good power banks do.

I purchased this to use with my Nintendo Switch2; it works great! It charges my switch while I'm playing it. It's very light and fits in my pocket or bag. I really like that the port is bendable and I can use it on the top or bottom of my device. It's a massive bonus that it stays up on it's own and doesn't have a long, dangling chord to mess with. It charges everything really really fast. My only complaint is capacity; it runs out of charge very quickly. It essentially quickly super charges the device and then its dies. The price was really reasonable so I purchased two.

I've used the similar Anker 5,000 mAh power bank (portable battery charger) that has the lightning connector for my iPhone 13, but my newer iPhone 17 has a USB-C port for charging. Therefore I ordered this USB-C power bank. Other than the connector type they seem the same. I like them because the are small and need no cord for attaching to your phone or other device. (They do use a cord when recharging the power bank itself through the port on the side.) The USB-C port on the side can also charge a device through a cord; it is an In/Out C-port. It can therefore charge devices that don't have a C-port as long as your cord has a C-connector on one end and your device's connector type on the other end. At 5,000 mAh this will provide about one full phone charge or top off a few devices. The smaller power capacity allows it to be more compact and lighter. This one charges devices fast and recharges fast, by my standards. Airlines allow power banks of up to 20,000 mAh so this one is well within TSA allowed limits. All power banks must go in carry-on bags, never in checked luggage because of the fire hazard of all lithium-ion batteries. I considered the thin, flat magnetic Anker power bank that sticks to the back of the phone, but decided on this one instead because this one is faster and can also be used to charge my earbuds, Kindle, and Fire tablets. Anker is a brand that is generally trusted for this type of device. A note on the blue colors... My old lightning-connector power bank was a very light aqua-tinted or sky blue, but this one is a truer blue and a little deeper color. Both are pretty colors for my blue iPhones.

Only has enough charge for one charge. Slow charging but on the plus side it’s slim and small

Absolutely love this thing, I've had it for over a year now and it has held up spectacularly well. I mainly used it for days when I went on Pokemon Go but it quickly turned into a must-have in my every day bag. It charges quick, tops up the phone perfectly while letting me still use the phone, and comes in clutch with my iPad mini too in case I forgot to charge it before the gym! It doesn't add much weight to my bag nor is it uncomfortable to hold my phone while it's attached. Of course it makes it a little bottom heavy but the tradeoff is worth it while it charges. 10/10 recommend. I got the purple one and it matches pretty perfectly with my Galaxy Fold 8 in lavender as well, in case that matters :)

Tenho um Poco X7 Pro, essa bateria carregou de 0% → 60% em situação ideal, sem mexer no celular... Usando ele como é pensado pra ser usado, deve carregar perto de 50%, o carregamento que ele proporciona é rápido, mesmo com você mexendo da pra ver que a bateria sobe, não fica estacionada como outras baterias de carregamento mega lento... A fixação é boa, usando normalmente não deve cair nunca, mas como uso o celular no suporte na moto, precisei fazer uma gambiarra na capinha do celular como uma espécie de "cinto de segurança" pra poder usar ela mesmo andando de moto... Eu uso o celular literalmente o tempo todo, trabalho usando o celular e preciso sempre de estar com o brilho no maximo pois uso o celular no sol da manhã entre 8h e 15h na moto, e com bluetooth e 5g sempre ligados... E com essa bateria consigo usar o celular mais de 12 horas, mesmo depois de chegar em casa ainda consigo usar o celular de maneira mais leve até a hora de dormir, quando ponho tudo pra carregar... Sinceramente, me atende muito bem, pra mim serviu perfeitamente pro que eu precisava, fazer a bateria do celular durar o dia todo rodando fazendo entregas, é extremamente compacto relativamente leve, levo no meu bolso quando não estou usando e não me incomoda nenhum pouco, nota 10/10, não tenho pontos a reclamar, valeu cada centavo.

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

Excellent powerbank very compact and light weight enough juice for day to day life

Compré este cargador portátil de Anker buscando algo extremadamente ligero y fácil de llevar, y este modelo de 5000 mAh superó mis expectativas en portabilidad. ​✅ Lo que me encanta ​Ultra-Portátil: La característica que más me gustó es que prácticamente no pesa. Es ideal para meter en el bolsillo o un bolso pequeño sin que se sienta voluminoso. ​Diseño Perfecto: El diseño es compacto y ergonómico. Se adapta muy bien al teléfono mientras está cargando, lo que me permite seguir usando el móvil cómodamente. ​Carga Fiable: Cumple su función principal: carga bien y de forma consistente, dándome la energía extra que necesito para terminar el día. ​⚠️ El único "pero" ​Mi única crítica tiene que ver con la relación capacidad-precio. Siento que, por lo que cuesta, Anker podría ofrecer un poco más de capacidad (quizás 7000 a 10000 mAh) para hacerlo una opción perfecta. ​💡 Conclusión ​Si tu prioridad es la portabilidad absoluta y la confianza de una marca como Anker, este Power Bank es una compra excelente. Si necesitas cargar tu teléfono dos o tres veces al día, quizás debas buscar un modelo de mayor capacidad, pero si solo buscas una carga de emergencia fiable, ¡es perfecto!

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.
